First enacted in 1938, the Federal Food, Drug, and Cosmetic Act (FD&C Act), as amended, empowers the Food and Drug Administration (FDA) to regulate various products affecting public health, including food, drugs, medical devices, cosmetics, and tobacco products. By FDA's estimate, the products it oversees in 2025 were valued at $4.1 trillion and accounted for about 21 cents of every dollar spent by U.S. consumers. In general, the FD&C Act prohibits the distribution of a covered product in interstate commerce that is "adulterated" or "misbranded," and defines, for each product type, the circumstances and standards under which that product is "adulterated" or "misbranded." Additional statutory or regulatory provisions often further refine the specific federal requirements that apply to specific subsets or components of a product type. Some subsets of drugs, devices, and tobacco products, for instance, must be reviewed by FDA before they can be lawfully marketed, while food and cosmetic products (with the exception of certain ingredients) generally are not subject to premarket review.
States have historically regulated many products covered by the FD&C Act based on their general police power to provide for the public health and safety of their residents. State regulation of such products might include statutes specific to certain products, along with more general consumer protection and products liability laws. State consumer protection and products liability laws provide mechanisms by which consumers allegedly injured by a relevant product may challenge the product's promotion, manufacture, design, and/or warning, on the grounds that the defendant manufacturers should have taken a different course of action with respect to those activities—some of which may be regulated by the FD&C Act and its implementing regulations.
Under the U.S. Constitution's Supremacy Clause, federal law supersedes (preempts) conflicting state law and can do so expressly—through explicit preemption provisions specifying the scope of preempted state law—or impliedly—where a state law is displaced because it conflicts with federal law or because federal law so thoroughly occupies the regulatory field as to leave no room for state activity. Over the FD&C Act's nearly 90-year history, Congress has amended the law to include provisions that expressly preempt certain state laws that address areas specifically regulated by the FD&C Act, such as state laws imposing requirements on the safety and efficacy of medical devices, labeling requirements for food and cosmetic products, and requirements on certain standards for tobacco products. In other instances, Congress has not spoken specifically to preemption, as is the case for FD&C Act provisions governing prescription drugs.
Courts—including the Supreme Court—have frequently considered the preemptive scope of the FD&C Act on state statutes and causes of action—an inquiry the Court has sometimes described as focused on discerning the intent of Congress. In practice, courts often look to the text, structure, and contextual background of the relevant FD&C Act provisions to determine their preemptive scope. This report provides an overview of the courts' FD&C Act preemption jurisprudence, focusing on the following FDA-regulated products: food products, prescription drugs, medical devices, cosmetics, and tobacco products. Generally speaking, these cases illustrate that while the FD&C Act's enforcement scheme impliedly preempts a particular type of state fraud claim (i.e., one alleging that an applicant made misrepresentations to FDA during a premarket review process), context-specific analyses are usually required to assess whether other state laws or claims are preempted. In these analyses, courts typically undertake a case-specific, often granular, comparative analysis of what an applicable federal law requires or permits and whether and to what extent the relevant state requirements conflict with federal requirements. The courts' nuanced approach often results in the preservation of at least some state claims or requirements—a result that arguably reflects the courts' recognition of states' long-standing, concurrent role in the regulation of these products. State requirements are most likely to survive preemption where Congress is silent on the interaction of federal and state law, but courts have sometimes understood the FD&C Act's express preemption provisions as leaving room for certain state requirements. At the same time, courts may be more likely to construe relevant FD&C Act provisions to have broader preemptive effect on certain aspects of product regulation that are not historically regulated by states. These considerations may inform Congress's decision on whether to modify existing express preemption provisions, add additional express preemption provisions, and consider the appropriate degree of specificity of any such provisions.
Under the United States' federalist system, the federal government and states share regulatory authority over public health matters, with states traditionally exercising the bulk of the authority pursuant to their general police power.1 This inherent power enables states, within constitutional limits, to enact laws "to provide for the public health, safety, and morals" of the states' inhabitants.2 At the same time, the federal government shares certain concurrent authority in this area emanating from its enumerated powers in the Constitution.3 The regulation of products implicating public health—including food, drugs, biologics, medical devices, cosmetics, and tobacco products—reflects this overlapping authority.
Since 1906, Congress has enacted laws regulating products affecting public health, relying on its authority under the Commerce Clause to regulate persons or things in or affecting interstate commerce.4 The Pure Food and Drug Act of 1906 prohibited the sale of misbranded or adulterated food and drugs in interstate commerce.5 In 1938, Congress replaced that law with the Federal Food, Drug, and Cosmetic Act (FD&C Act, or the Act).6 As amended over the years, the FD&C Act provides the federal legal framework governing the regulation of food, drugs, cosmetics, medical devices, tobacco, and other products. By the Food and Drug Administration's (FDA's) own estimate, the products it oversees in 2025 were valued at $4.1 trillion and accounted for about 21 cents of every dollar spent by U.S. consumers.7
Under its general framework, the FD&C Act prohibits the distribution of a covered product in interstate commerce that is "adulterated" or "misbranded."8 The Act then defines, for each product type, the circumstances and standards under which that product is "adulterated" or misbranded."9 Some regulated products are required to be reviewed by FDA before they can be lawfully marketed while other products are not. The 1938 law, for example, transformed the regulation of new drugs from a regime that removed harmful drugs off the market after the fact, to a regime that mandates premarket approval of new drugs—that is, a regime under which manufacturers of new drugs must demonstrate the products' safety before they can be sold on the market.10 Over time, that premarket approval regime expanded to include a determination of efficacy in addition to safety.11 Congress also applied the premarket review framework—with different product-specific standards—to the regulation of other products, including certain medical devices12 and tobacco products.13 Other products, such as food and cosmetic products, are generally (with the exception of certain ingredients)14 not subject to premarket review but are subject to other federal requirements.15
Meanwhile, states maintain a role in the regulation of these products, often through a diverse set of laws that reflect the piecemeal approach to regulation that began in the 1800s.16 For instance, while a majority of states have adopted the Uniform State Food, Drug, and Cosmetic Act based on the 1938 FD&C Act, significant variations remain among the food and drug laws of the different states because not all states have adopted all parts of the Uniform Act or incorporated all amendments to the federal FD&C Act.17
In addition to state statutes that specifically address products regulated by the FD&C Act, states have also enacted general consumer protection statutes that prohibit, to varying degrees, deceptive or unfair business practices.18 These state consumer protection laws provide a mechanism for consumers allegedly harmed by a relevant product to seek redress for such harm if it stems from a prohibited practice.19
Finally, state tort law—developed through judicial decisions—applies to FD&C Act-regulated products.20 State tort law, and in particular, products liability law, provides an avenue for individuals harmed by a product to assert claims challenging the manufacture, design, or warning of the product.21
The interaction between these sometimes overlapping federal and state laws implicates the preemption doctrine. Under the Constitution's Supremacy Clause,22 federal law supersedes (preempts) conflicting state laws.23 The Supreme Court has identified two general types of preemption: express and implied preemption. Federal law expressly preempts state laws when a federal statute or regulation contains explicit preemptive language.24 Even when Congress is silent on a federal statute's preemptive effect, a state requirement can be impliedly preempted where it conflicts with federal law or where federal law so thoroughly occupies the regulatory field as to leave no room for state regulation.25
The FD&C Act implicates both express and implied preemption. Over the years, Congress has amended the Act to expressly preempt certain regulated products or topics, but sometimes there is uncertainty regarding these provisions' scope.26 In other instances, Congress has not spoken directly to the preemptive effect of the FD&C Act's regulation of a particular matter, leaving it to courts, in disputed cases, to determine when or whether a state requirement is impliedly preempted.27 Both express and implied preemption questions can arise when states regulate products or issues addressed directly by the FD&C Act, or when state law provides a cause of action (e.g., through products liability or consumer protection laws) for injuries allegedly caused by an FDA-regulated product.28
This report provides an overview of the courts' FD&C Act preemption jurisprudence, focusing on certain FDA-regulated products. It begins with an overview of the preemption doctrine, and then examines the doctrine as applied to the FD&C Act's general enforcement scheme as well as to the Act's product-specific regulatory schemes for the following categories of FDA-regulated products: (1) food products; (2) prescription drugs; (3) medical devices; (4) cosmetics; and (5) tobacco products.29 For each product type, the discussion first highlights the relevant FD&C Act provisions, including any express preemption provisions, and then analyzes how courts have interpreted those provisions to determine their preemptive scope. The report concludes with selected observations and considerations for Congress.
The U.S. Constitution's Supremacy Clause provides that "the Laws of the United States . . . shall be the supreme Law of the Land" notwithstanding "the Constitution or Laws of any State to the Contrary."30 As interpreted by the Supreme Court, this Clause forms the basis of the federal preemption doctrine, under which federal law supersedes state laws if state laws "interfere with, or are contrary to federal law."31 In describing the inquiry into whether—and to what extent—a federal law preempts state law, the Court has at times said that discerning congressional intent is the "ultimate touchstone" in the analysis.32 In practice, the Court has, to varying degrees, considered the text, structure, purpose, and contextual background of a federal statute when considering its preemptive effect.33
Federal law can preempt state law either expressly or impliedly. Express preemption occurs when a state law is displaced by explicit preemptive language—often called an express preemption provision—contained in a federal statute or regulation.34 In those instances, determining the scope of the preemption clause is largely a matter of statutory construction.35 The Supreme Court has instructed that Congress's intent with respect to express preemption is discerned "primarily" from a statute's text, but the Court has also often looked to the larger context and purpose of the particular statutory scheme, particularly in the context of discerning the preemptive scope of the FD&C Act.36
Even where a federal law's express preemption provision does not preempt a state law or where a federal law lacks an express preemption provision altogether, the federal law can still impliedly preempt state law when Congress's preemptive intent is implicit in the relevant federal law's structure and purpose.37 The Supreme Court has identified two types of implied preemption: field preemption and conflict preemption.38 Field preemption occurs when Congress has evidenced a desire to occupy the entire field of regulation, such that there is "no room for the states to supplement it."39 Given states' traditional role in regulating the products subject to the FD&C Act, courts have often declined to apply field preemption in areas covered by the Act.40 However, in certain discrete contexts—such as drug importation—some courts have concluded that the relevant FD&C Act provisions evidenced an intent by Congress to occupy the regulatory field.41
The other type of implied preemption is the doctrine of conflict preemption, for which the Supreme Court has recognized two subcategories: impossibility preemption and obstacle preemption.42 Impossibility preemption can occur when it is "impossible for a private party to comply with both state and federal requirements."43 In addition to considering the relevant statutory text, context, and history, courts analyzing impossibility preemption tend to focus on a comparative analysis of the specific implementation of the federal law versus relevant state law.44 The Supreme Court has seldom invoked impossibility preemption45 and has described it as a "demanding defense" when used to defeat the effect of a state law.46 At the same time, the Court has twice relied on the doctrine to hold that federal labeling requirements for generic drugs preempt state law claims that would require generic drug manufacturers to provide different or additional warnings in the drugs' labeling.47
Obstacle preemption can occur if the implementation of state law "stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress."48 The Supreme Court has said that "[w]hat is a sufficient obstacle [for purposes of obstacle preemption] is a matter of judgment to be informed by examining the federal statute as a whole and identifying its purpose and intended effects."49 While obstacle preemption has played an important role in the Court's preemption jurisprudence since the mid-20th century, and has been invoked by the Court in the FD&C Act context to preempt certain state-law claims,50 some Justices have called the doctrine into question. In particular, they criticize the doctrine for "invalidat[ing] state laws based on perceived conflicts with broad federal policy objectives, legislative history, or generalized notions of congressional purposes that are not embodied within the text of federal law."51
An area of potential uncertainty is whether and under what circumstances should a canon of statutory construction known as "presumption against preemption" apply.52 This canon, rooted in principles of federalism and respect for state sovereignty, generally instructs that courts should not construe a federal law to preempt a state law implicating the state's historic police powers "unless that was the clear and manifest purpose of Congress."53 In preemption cases, the Supreme Court has at times applied this canon and described it as one of the "cornerstones" of its preemption jurisprudence.54 Other times, however, the Court has resolved preemption questions without referencing the canon.55 The Court's FD&C Act preemption cases reflect this inconsistency.56 As discussed further below, the Court has, for instance, relied on the canon to hold that the FD&C Act did not preempt a state-law claim alleging that a brand-name prescription drug manufacturer failed to provide adequate warning of a drug's risks.57 At the same time, the Court, without referencing the presumption, has also held that the FD&C Act preempted state-law claims alleging similar failure-to-warn claims against a generic manufacturer.58 Lower courts have also disagreed over whether the presumption applies when a case involves the interpretation of an express preemption clause.59
Over the FD&C Act's nearly 90-year history, Congress has significantly expanded the scope of products subject to the law. The original 1938 FD&C Act regulated drugs, food, medical devices, and cosmetics,60 but over time, Congress amended the law to add or refine the products—such as food additives, dietary supplements, and tobacco products—subject to FDA regulation.61 Despite its expansion, the FD&C Act's general structure and framework from 1938 remains.
At its heart, the FD&C Act prohibits the distribution of a covered product in interstate commerce that is "adulterated" or "misbranded."62 The Act then defines, for each product type, the circumstances and standards under which that product is "adulterated" or "misbranded."63 The law provides FDA with a range of administrative tools to enforce the Act, including warning letters, import alerts, recalls, debarments, and civil money penalties.64 The scope of some of these administrative tools differs between product types.65 For all product types, however, a violation of the FD&C Act can subject a person to civil or criminal enforcement actions before a federal court.66 With limited exceptions for certain actions that may be brought by a state, the FD&C Act generally requires "all such proceedings for the enforcement, or to restrain violations of [the FD&C Act]" to be "by and in the name of the United States," precluding a private plaintiff from suing to enforce an FD&C Act requirement.67 Courts have considered both the preemptive effect of the FD&C Act's general enforcement scheme, as well as the preemptive effect of FD&C Act's product-specific provisions.
The FD&C Act's general enforcement scheme, the Supreme Court has held, impliedly preempts certain state-law claims based on the theory that a regulated entity made misrepresentations to FDA during a premarket review process to obtain FDA approval. In Buckman v. Plaintiff's Legal Committee, plaintiffs with injuries resulting from the use of orthopedic bone screws sued a consulting company that had assisted the screw manufacturer in obtaining FDA clearance to market the devices.68 The plaintiffs, asserting state tort law claims, alleged that the manufacturer committed fraud on the FDA by giving the agency misleading information in order to obtain this clearance.69 The plaintiffs argued that had the proper information been provided to the agency, FDA would not have cleared the devices and the plaintiffs would not have been injured.70
Relying on implied preemption principles—and more specifically, obstacle preemption principles—the Court held that the plaintiffs' state-law "fraud-on-the-FDA" claims were preempted because they conflicted with the federal scheme for enforcing the FD&C Act.71 In the Court's view, given that the FD&C Act "leaves no doubt that it is the Federal Government rather than private litigants who are authorized to file suit for noncompliance with the medical device provisions,"72 state-law fraud-on-the-FDA claims "inevitably conflict with the FDA's responsibility to police fraud consistently with the Administration's judgment and objectives."73 The Court observed that where a regulated product is subject to a comprehensive premarket review scheme like the medical device at issue, "complying with the FDA's detailed regulatory regime in the shadow of 50 States' tort regimes will dramatically increase the burdens facing potential applicants."74 In the Court's view, such burdens were "not contemplated by Congress" when it enacted the FD&C Act and the Act's amendments governing medical devices.75
While Buckman specifically involved a medical device subject to a premarket review process known as the section 510(k) clearance process,76 the Court's reasoning—premised on the FD&C Act's enforcement scheme that applies across product types—suggests that state-law "fraud-on-the-FDA" claims related to other products subject to FDA premarket review could be similarly impliedly preempted under Buckman.77 Subsequent case law, however, shows that this analysis can depend on the specific structure and operation of applicable state laws. Several states, for example, have enacted state statutes that generally insulate drug manufacturers from certain tort claims so long as FDA approved the product at issue.78 These state laws, however, also contain an exception that preserves tort liability if the manufacturer withheld or misrepresented information that would have altered FDA's approval decision.79 In other words, under these state statutes, a plaintiff must provide evidence of fraud-on-the-FDA not as part of asserting such a claim, but as a prerequisite to asserting an underlying products liability claim.80 Several lower courts have considered whether state tort claims asserted under this type of statutory exception were impliedly preempted under Buckman, and they have reached different conclusions. At least two appellate courts concluded that because the applicable state law "ultimately requires the plaintiff to prove that the drug manufacturer defrauded the FDA, it conflicted with the FDA's duties and was preempted" under Buckman.81 Another appellate court, however, concluded that under the relevant state law, the plaintiffs "[were] not pressing 'fraud-on-the-FDA' claims" subject to preemption under Buckman, but rather, they were "asserting claims that sound in traditional state tort law."82 Because the plaintiffs' claims, in the court's view, were "premised on traditional duties between a product manufacturer and . . . consumers" and were not "derive[d] from, or . . . based on, a newly-concocted duty between a manufacturer and a federal agency," such claims were not preempted under Buckman.83
More broadly, lower courts have also considered whether state-law claims based on state laws that incorporate or mirror FD&C Act requirements are impliedly preempted under Buckman. The courts that have considered this question have generally concluded that such claims were not preempted.84 In Davidson v. Sprout Foods, Inc., consumers of certain baby food products sued the product maker, alleging that the relevant product labels violated California's Sherman Law, which incorporates by reference all federal food labeling requirements.85 The defendant argued, and the district court agreed, that the plaintiffs' state claims were preempted under Buckman because "Sherman Law depends upon and adopts the [FD&C Act] and regulations as state law," and thus the claims amounted to an impermissible attempt to privately enforce the FD&C Act.86 Reversing the district court, the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) held that the plaintiffs' claims based on the Sherman Law were not impliedly preempted because the FD&C Act "did not . . . purport to limit enforcement of . . . parallel state laws in any way."87 The Ninth Circuit observed that unlike Buckman, in which the plaintiffs' state-law claims were premised solely on violations of FD&C Act duties, the Davidson plaintiffs' claims were based on violations of state-law duties, which happened to impose identical standards as federal law.88 The U.S. Court of Appeals for the Fifth Circuit (Fifth Circuit) applied similar reasoning in Zyla Life Sciences, L.L.C. v. Wells Pharma of Houston, L.L.C.89 The Fifth Circuit held that a drug manufacturer's claims against a competing compounding pharmacy based on state unfair competition law that incorporated federal standards were not impliedly preempted.90
While the core structure and general enforcement scheme of the FD&C Act has remained the same since 1938, the law's product-specific provisions and standards have evolved over time and vary based on a particular product type's nature and risk profile. Over the years, Congress—in addition to amending the product-specific standards and provisions—has also added express preemption provisions in certain parts of the FD&C Act. The Act had no express preemption provisions until 1976, when Congress enacted the Medical Device Amendments (MDA).91 The MDA includes a provision that preempts state laws imposing additional or different requirements related to the safety and efficacy of medical devices.92 Since 1976, Congress has added several preemption provisions that apply to specific product categories or topics, including with respect to food labeling,93 cosmetics labeling and packaging,94 and certain tobacco product standards.95
Courts, including the Supreme Court, have weighed in on the preemptive scope of these product-specific FD&C Act provisions on many occasions. Many of these cases focus on the extent to which the FD&C Act preempts state tort or consumer protection law claims.96 Because the products regulated by the FD&C Act are generally consumer products, injuries allegedly caused by such products implicate both state tort law—specifically, state products liability law97—and state laws protecting consumers from unfair or deceptive practices.98 In suits that alleged products liability claims, the plaintiffs often asserted that the manufacturer had defectively manufactured or designed the product at issue, or failed to provide adequate warning of certain risks.99 Had the manufacturers differently manufactured or designed the product, or provided certain different or additional warnings, the plaintiffs typically alleged, they would have avoided the injuries.100 With respect to consumer protection claims, the plaintiffs often alleged that the manufacturers deceptively or unfairly marketed the relevant products in a manner that harmed the plaintiffs.101 In addition to these tort and consumer protection claims, some courts have also considered whether and to what extent the FD&C Act preempted certain state statutes enacted to address certain products or topics also regulated by the Act.
The sections below provide an overview of the preemptive scope of the FD&C Act's product-specific provisions for food products, prescription drugs, medical devices, cosmetics, and tobacco products. For each product type, the discussion begins with an overview of selected FD&C Act provisions and continues with an analysis of relevant case law regarding the provisions' preemptive scope.
The original 1938 FD&C Act prohibited the introduction of misbranded or adulterated food in interstate commerce.103 Under the law, such food products were misbranded if, for instance, their labeling included false and misleading statements; such products were adulterated, for instance, if their content did not comply with established mandatory food standards called standards of identity.104 Over the years, Congress amended the FD&C Act's food provisions on many occasions to impose additional requirements.105 For example, while most food products do not need to undergo premarket review before they can be lawfully marketed, Congress, under the Food Additives Amendment of 1958106 and the Color Additive Amendments of 1960,107 created a system of premarket review of certain food ingredients. In 1990, Congress also enacted the Nutrition Labeling and Education Act (NLEA), which amended the FD&C Act to establish uniform labeling requirements for food sold in interstate commerce.108
Under current law, food products must comply with various labeling requirements. For instance, a food label must bear,109 if applicable, the name of the food specified in the relevant standard of identity, which defines the mandatory or optional ingredients and characteristics of a food.110 If there is no relevant standard of identity, the food label must bear the common or usual name of the food.111 A food is deemed misbranded under the Act if the food's label represents the product as a food for which a standard of identity has been issued, and the product does not conform to the definition.112
Labels of food in package form must also bear nutrition information, including the serving size, the number of servings per container, and the amounts of nutrients in each serving size.113 This information must appear on an "information panel," or the part of the label immediately to the right of the package's principal display that is most likely to be shown to consumers in retail sale.114 In addition, FDA regulations set out requirements for nutrient content claims that may be included on food packages.115 A nutrient content claim characterizes the level of a nutrient in a product.116 If a manufacturer chooses to include a nutrient content claim on a product's label,117 the claim must meet the applicable regulatory requirements.118 For example, FDA regulations define many terms, including "more," "fortified," "enriched," "high potency," "light ," "free," and "low" and specify the conditions under which manufacturers may use these terms on their labels.119
In addition to labeling requirements, FDA must approve the use of certain food ingredients called food additives as safe before they can be used in products.120 Food containing any food additive that has not been approved as safe is deemed to be adulterated and may be subject to FDA enforcement.121 The FD&C Act defines food additive as "any substance the intended use of which results or may reasonably be expected to result, directly or indirectly, in its becoming a component or otherwise affecting the characteristics of any food" if the substance is not generally recognized as safe (GRAS).122 A substance is GRAS—and therefore not a food additive subject to premarket review—if "experts qualified by scientific training and experience to evaluate its safety" generally recognize the intended use of the substance to be safe.123 According to this statutory definition, qualified experts must base their view of a general recognition of safety on either (1) scientific procedures or (2) common use of a substance in food prior to January 1, 1958.124 FDA has promulgated regulations recognizing certain ingredients as GRAS, which is sometimes called the GRAS list.125 This list, however, is not comprehensive because it "is impracticable to list all substances that are [GRAS]."126
Recognizing the role that states and localities traditionally play in food regulation, Congress has directly addressed the interplay between the FD&C Act and state and local law through several express preemption and "no preemption" provisions. For example, section 416 of the FD&C Act directs FDA to promulgate regulations that generally require those engaged in the transportation of food to use sanitary transportation practices prescribed by the agency.127 Subsection (e) of section 416 generally preempts state or local requirements "concern[ing] the transportation of food" if complying with both federal and state/local requirements is impossible or if complying with state/local requirements presents an obstacle to carrying out the federal requirements.128 On the other hand, other FD&C Act provisions, under the heading of "No preemption," expressly preserve any non-federal requirements.129 FD&C Act section 418(i)(6), for example, expressly preserves any "non-Federal law regarding the safe production of food."130 Similarly, section 419(f)(5) preserves any "non-Federal law regarding the safe production, harvesting, holding, transportation, and sale of fresh fruits and vegetables."131
With respect to food labels, the FD&C Act, as amended by the NLEA, also includes an express preemption provision, entitled "National Uniform Nutrition labeling," that forbids states and localities from establishing any requirement that is "not identical to" specified federal requirements related to food labeling.132 This labeling preemption provision (FD&C Act section 403A) states the following:
(a) Except [in certain circumstances], no State or political subdivision of a State may directly or indirectly establish under any authority or continue in effect as to any food in interstate commerce—
(1) any requirement for a food which is the subject of a standard of identity established under section [401] of this title that is not identical to such standard of identity or that is not identical to the requirement of section [403(g)] of this title, except [in certain circumstances],
(2) any requirement for the labeling of food of the type required by section [403(c), 403(e), 403(i)(2), 403(w), or 403(x)] of this title that is not identical to the requirement of such section, except [in certain circumstances],
(3) any requirement for the labeling of food of the type required by section [403(b), 403(d), 403(f), 403(h), 403(i)(1), or 403(k)] of this title that is not identical to the requirement of such section, except [in certain circumstances],
(4) any requirement for nutrition labeling of food that is not identical to the requirement of section [403(q)] of this title, except [in certain circumstances], or
(5) any requirement respecting any claim of the type described in section [403(r)(1)] of this title made in the label or labeling of food that is not identical to the requirement of section [403(r)] of this title, except [in certain circumstances].133
This preemption provision cross-references numerous requirements or prohibitions of the FD&C Act's misbranded food section under section 403.134 The cross-referenced provisions include, for instance, labeling requirements related to a food's standard of identity, nutritional information, and nutrient content claims, limiting states' ability to establish requirements that are "not identical" to these federal requirements.135
The NLEA also contains a savings clause that limits FD&C Act section 403A's preemptive effect and expressly preserves certain types of state laws or remedies.136 The clause provides that "[the NLEA] shall not be construed to preempt any provision of State law, unless such provision is expressly preempted under FD&C Act section 403A."137 It further states that section 403A "shall not be construed to apply to any requirement respecting a statement in the labeling of food that provides for a warning concerning the safety of the food or component of the food."138 The provision also clarifies that section 403A "shall not be construed to affect" the preemptive scope of any other provision of the FD&C Act.139
To date, courts that have considered the preemptive effect of the FD&C Act provisions governing food products have primarily considered whether and to what extent FD&C Act section 403A expressly preempts consumers' state-law claims regarding a food label. These consumer claims generally involve state consumer protection or tort claims alleging that a food label is misleading or does not adequately warn of the risks associated with a food product.140 In addition, at least one court has considered the preemptive effect of FDA's GRAS determination on a state statute prohibiting that substance.141
Case Law on the Preemptive Scope of FD&C Act Section 403A on Food Labeling
Although the U.S. Supreme Court has not addressed the scope of FD&C Act section 403A, lower courts have opined on the extent to which consumer state-law claims are preempted by the clause. Generally, lower courts have held that state-law claims that were interpreted to impose additional or different labeling requirements from what applicable FDA regulations require were preempted because such state claims sought to impose labeling that was "not identical" to federal requirements under FD&C Act section 403A.142
For example, in Pardini v. Unilever United States, the Ninth Circuit considered the plaintiffs' allegations that the "I Can't Believe It's Not Butter! Spray" product's label misrepresented its fat and calorie content.143 The plaintiffs alleged that the front of the product's label, which claimed that it has 0 calories and 0 grams of fat, was misleading because the 12-ounce bottle of the product contains 1160 calories and 124 grams of fat.144 The defendant argued that the plaintiffs' claim that the label was misleading was preempted because the label's claims complied with FDA regulations that specifically governed "zero fat" claims and that the plaintiffs were seeking to impose different labeling requirements.145 The court agreed with the defendant. In particular, the court observed that under applicable FDA regulations, for products categorized as a "spray type," their amount of fat and calories must be expressed in terms of a prescribed serving size of 0.25 grams.146 When the amount of fat and calories in a designated serving size was below a certain threshold (5 calories and 0.5 grams of fat), the regulations also required the product to reflect that the product has zero calories or fat per serving on the label's information panel.147 The court concluded that because the defendant properly categorized the product as a "spray type," its nutrition labeling complied with the relevant requirements, which allowed for the defendant to round the amount of calories and fat down to zero.148 Accordingly, the court held that the plaintiffs' claim—which would have required the defendant to label the product differently from what FDA regulations required—was expressly preempted.149
Courts have also held that state-law claims seeking to impose additional disclosures beyond what FDA regulations require would impose a requirement that is "not identical to" the FD&C Act requirements and are therefore preempted.150 For example, in Turek v. General Mills, the manufacturer of a "chewy bar" included claims on the front of its label that the product contained "35% of your daily fiber" and called it "Fiber Plus."151 The plaintiff alleged that the product contained "non-natural fiber" which provided fewer of the benefits of consuming fiber, may cause stomach problems in some people, and may be harmful to women who were pregnant or breastfeeding.152 The plaintiff argued that the product's label was misleading because it did not disclose that the product used an inferior form of fiber that was not "natural" and may be harmful to some.153 The U.S. Court of Appeals for the Seventh Circuit (Seventh Circuit) held that the labeling claims challenged by the plaintiff were compliant with all applicable FDA regulations related to dietary fiber.154 Because the disclaimers the plaintiff sought to add to the label "[were] not identical to the labeling requirements imposed on such products by federal law," they were expressly preempted.155
In contrast, courts have generally held that two kinds of state-law claims are not preempted by FD&C Act section 403A: (1) state claims that allege as false or misleading certain labeling claims that a defendant is not specifically required or permitted to include by FDA regulations;156 and (2) state claims that seek to impose requirements interpreted to be identical to what federal law requires.157
Courts have generally held that claims focused on additional labeling claims not specifically required or permitted by FDA regulations that a defendant chose to include were not preempted by FD&C Act section 403A.158 For example, in Hawkins v. Kroger Company, the Ninth Circuit held that a plaintiff's claim—that a bread crumb product's front label stating that the product had "0g Trans Fat per serving" was misleading because the product did have small amounts of trans fat—was not preempted.159 The court observed that while FDA regulations required the amount of trans fat per serving to be stated on the information panel on the side of the label and required such amount to be expressed as zero "[i]f the serving contains less than 0.5 gram," these requirements did not apply to nutrient content claims—which can only be made if they were not "false or misleading in any respect"—on the front of the label.160 The court further observed that FDA had "explicitly decided not to authorize a 'No Trans Fat' nutrient content claim in light of a lack of scientific information."161 Accordingly, the court held that because FDA regulations did not "authorize the contested statement," the state-law claims were not preempted.162
Similarly, in Bell v. Publix Super Markets, the Seventh Circuit held that certain consumers' state-law claims—that a product's label stating it was "100% Grated Parmesan Cheese" was misleading because the product contained cellulose powder and potassium sorbate to prevent the grated cheese from caking and getting moldy—were not preempted by federal law.163 Under federal law, grated cheese is subject to an FDA standard of identity that allows products labeled as "grated cheese" to include cellulose powder and potassium sorbate,164 and the defendant argued that because it had complied with the standard, the plaintiffs' claims were preempted because they sought to impose different standard-of-identity requirements.165 The Seventh Circuit rejected this argument, reasoning that because the standard-of-identity regulation does not address whether products may be labeled with an additional modifier such as "100%," a state-law claim seeking to prevent its use in certain circumstances did not establish a new requirement different from the standard of identity.166 Because the plaintiffs were seeking to "stop defendants from voluntarily adding deceptive language to the federally permitted label,"167 the court concluded that the state-law claims based on defendant's use of the "100%" modifier were not preempted.168
A second category of state-law claims that courts have held are not preempted by FD&C Act section 403A are those that seek to impose requirements interpreted to be identical to those set out in FDA regulations.169 For example, in Lilly v. ConAgra Foods, the Ninth Circuit concluded that a plaintiff's claim under state law—that defendant's sunflower seed label misrepresented the amount of sodium content of the sunflowers—was not preempted by federal law.170 The plaintiff alleged that the sunflower seed label declared the amount of salt in the sunflower seed but did not include the amount of salt that was in the coating on the sunflower shell.171 The defendant argued that under federal law, manufacturers need not include the amount of sodium on inedible components like the shell, and therefore the plaintiff's claim imposed requirements that differed from federal requirements and thus was preempted.172 Siding with the plaintiff, the court observed that applicable FDA regulations required declaration of the amounts of nutrient and food component content to be "based on only the edible portion of food, and not bone, seed, shell, or other inedible components."173 The court reasoned that, even though the sunflower seed shell is not meant to be consumed, the coating on the shell is edible and therefore must be included in the sodium declaration on the food's label.174 The court concluded that because the "plaintiff's state-law claims, if successful, would impose no greater burden than those imposed by federal law, her state-law claims [were] not preempted."175
Case Law on the Preemptive Scope of FDA's GRAS Regulation
While the majority of courts that have considered the preemptive effect of the FD&C Act's food provisions have focused on section 403A, at least one court has considered the implied preemptive effect of the FD&C Act's food additive and GRAS regulations on state statutes that restrict the use of certain substances in food.176 Concerns over the safety of certain food ingredients have led several states to enact legislation that would prohibit the use of certain food substances.177
In Marrache v. Bacardi, the U.S. Circuit Court for the Eleventh Circuit (Eleventh Circuit) considered a Florida law that banned adding certain substances to liquor and held that the state law was not preempted.178 The Florida law at issue banned the use of, among other things, grains of paradise, a botanical that was used in one of the defendant manufacturer's gin products.179 Grains of paradise, however, is included on the non-exhaustive list of GRAS substances promulgated by FDA and expressly identified by the agency as "generally recognized as safe."180 A consumer sued the defendant manufacturer, asserting that the defendant violated state consumer protection laws by selling products containing an ingredient banned under state law.181 In response, the defendant argued, among other things, that the plaintiff's claims were preempted because the underlying state law conflicted with applicable federal regulations because it prohibited the use of a food substance FDA had specifically found to be GRAS.182
The court rejected the defendant's argument, concluding that the state law was not preempted because it was not impossible for the defendant to comply with both state and federal law, nor did the Florida law frustrate the purposes of the Food Additives Amendment.183 The court first concluded that compliance with both laws was possible because while FDA had determined grains of paradise to be GRAS, permitting them to be included in food or alcohol, neither the FD&C Act nor its implementing regulations required foods with grains of paradise to be sold in all states.184 Thus, the court reasoned, the defendant may comply with both federal and state law "by selling [its product] without grains of paradise in Florida while selling [its product] with grains of paradise in other states."185 The court next concluded that the Florida law did not frustrate Congress's purpose in enacting the Food Additives Amendment.186 Congress's purpose in enacting the Food Additives Amendment—"as derived from the statutory text—was to prohibit unsafe food additives from being included in food and alcohol to protect the health and safety of the public."187 The court reasoned that the statute does not indicate that Congress intended to require states to allow the sale of GRAS substances.188
Since the original FD&C Act was enacted in 1938, there has been a federal system of premarket review of new drugs in the United States.189 The initial system, however, was more akin to a notification system. The process required a manufacturer to submit a new drug application, including evidence of the drug's safety, to FDA for review but generally allowed the application to take effect after 60 days unless FDA could show that the drug was not safe for use as labeled.190 In 1962, Congress enacted the Kefauver-Harris Drug Amendments (Drug Amendments) in response to incidences of birth defects caused by thalidomide in other countries, revamping the drug preapproval process.191 The Drug Amendments not only require FDA to affirmatively approve a new drug application before a drug could be marketed, shifting the burden to prove safety from FDA to the manufacturer, but also require that a manufacturer demonstrate that a new drug is both safe and effective for its intended use.192
Under current law, to market a new drug, a manufacturer must file with FDA a New Drug Application (NDA), which must include, among other things, "full reports" of investigations into the drug's safety and effectiveness; a list of the drug's components; and "specimens of the labeling proposed to be used for such drug."193 The FD&C Act directs FDA to deny an NDA if it finds, for example, the reports of testing show that the drug is unsafe or ineffective or if the "proposed labeling" does not make the drug "safe for use under the conditions prescribed, recommended, or suggested."194 Where "necessary to ensure that the benefits of the drug outweigh the risks," FDA may also approve a drug subject to a risk evaluation and mitigation strategy, or REMS.195 A REMS is a drug safety plan that mitigates the risks of a drug using strategies beyond FDA-approved labeling.196 Such strategies may include dissemination of additional patient information, development of a communication plan with health care providers, and restrictions on distribution (e.g., by requiring dispensing entities to obtain special certifications).197
Once FDA has approved an NDA, the agency places the drug at issue on a public list of approved drugs.198 The drugs on this list are known as listed drugs.199 The law requires post-market surveillance of the drug by FDA, and requires the agency to withdraw approval of a new drug if it finds that the drug is unsafe, or that there is a lack of substantial evidence that the drug is effective.200 The manufacturer must also comply with certain post-approval requirements, including reporting "adverse events" to FDA and periodically submitting any new information that may affect the FDA's previous conclusions about the safety, effectiveness, or labeling of the drug.201 While the manufacturer generally cannot make changes to the drug, including "[c]hanges in labeling," without obtaining FDA approval for the change,202 FDA's "Changes Being Effected" regulations permit a manufacturer to add or strengthen a warning without prior approval by FDA.203
If a manufacturer wants to market a generic version of an already-approved brand-name drug, the manufacturer can file an abbreviated new drug application (ANDA) to show that the generic drug is therapeutically equivalent to a brand-name drug (i.e., a listed drug).204 An ANDA generally must include "information to show that the new drug is bioequivalent to the listed drug,"205 and "information to show that the labeling proposed for the new drug is the same as the labeling approved for the listed drug."206 The generic applicant is not required to conduct its own safety and effectiveness testing, but is permitted to rely upon the safety and effectiveness evidence presented in the NDA for the listed drug.207 The FDA may withdraw approval of an ANDA for a generic drug if it finds that the labeling for the generic drug "is no longer consistent with that for the listed drug."208 The current NDA holder of a brand-name drug may change a drug's labeling, but a generic drug manufacturer cannot and generally must ensure that its labeling remains the same as the labeling for the listed drug.209
Drugs manufactured in foreign countries that are imported into the United States for commercial distribution must comply with the same FD&C Act requirements as domestically manufactured drugs, including premarket approval.210 Foreign-made drugs that have not undergone premarket approval, even if made with the same active ingredient as an FDA-approved drug, are generally considered unapproved new drugs that cannot be introduced into the U.S. market.211 FD&C Act section 801(d)(1)(B) explicitly prohibits the importation of unapproved prescription drugs for commercial use, with two exceptions: (1) when authorized by the Secretary of Health and Human Services (HHS) pursuant to a drug shortage, and (2) pursuant to an FDA-authorized drug importation program under FD&C Act section 804.212
Added to the FD&C Act in the early 2000s,213 section 804 authorizes FDA to promulgate regulations to establish a drug importation program under which pharmacists and wholesalers could import certain unapproved prescription drugs from Canada into the United States.214 In order for the program to become effective, the HHS Secretary must certify that the program would pose no additional risk to the public's health and safety and would offer "significant reduction in the cost" to U.S. consumers.215 The HHS Secretary made the requisite certification for the first time in 2020, and issued a final rule implementing the importation program.216 Under the program, states and Indian Tribes may submit proposals to FDA to, on a time-limited basis,217 import Canada-approved versions of certain FDA-approved prescription drugs.218 Section 804(j) grants FDA the authority to waive the importation requirements for certain cases of importation for personal use that are consistent with FDA guidance.219
The FD&C Act's prescription drug provisions do not contain an express preemption provision.220 Because prescription drugs are often the subject of state products liability lawsuits, courts are frequently confronted with questions regarding whether and to what extent the FD&C Act's elaborate premarket approval scheme for drugs impliedly preempts state-law claims that allege that a drug manufacturer inadequately warned of the risks of, or defectively designed, a drug. In addition to the premarket approval scheme, some courts have also considered how other aspects of the FD&C Act's prescription drug regulation—such as the Act's importation and REMS restrictions—impliedly preempt related state laws.
Case Law on the Preemptive Scope of Prescription Drug's Premarket Approval Scheme
With respect to the FD&C Act's preemption of state tort law claims, the Supreme Court has weighed in on these questions on multiple occasions, describing the preemption issues presented as "difficult . . . questions" that have "repeatedly vexed the Court."221 In several cases, the Supreme Court considered the circumstances under which the FD&C Act preempts state claims alleging that a drug manufacturer failed to provide adequate warnings about the risks of a drug.
In Wyeth v. Levine, the Court held that certain state claims that sought to strengthen the warnings of a brand-name prescription drug were not preempted as long as there was no "clear evidence" that FDA would deny approval of the warnings sought.222 Because the brand manufacturer was allowed under FDA regulations to add warnings without obtaining FDA approval, the Court reasoned, it may have been possible for the manufacturer to comply with both federal law and a state-law duty to strengthen warnings, so long there was not any "clear evidence that the FDA would not have approved" the change to the drug's label.223 Complying with a state-law duty to strengthen warnings also would not have obstructed the "purposes and objectives of federal drug labeling regulation."224 Congress, the Court observed, chose not to "provide a federal remedy for consumers harmed by unsafe or ineffective drugs in the 1938 statute or in any subsequent amendment."225 This choice, the Court reasoned, supported the application of the presumption against preemption and reflected Congress's "determin[ation] that widely available state rights of action provided appropriate relief for injured consumers" and perhaps the "recogni[tion] [that] state-law remedies further consumer protection by motivating manufacturers to produce safe and effective drugs and to give adequate warnings."226 More recently, in Merck Sharp & Dohme Corp. v. Albrecht, the Court clarified that "clear evidence" that FDA would have denied approval of warnings sought "is evidence that shows the court that the drug manufacturer fully informed the FDA of the justifications for the warning required by state law and that the FDA, in turn, informed the drug manufacturer that the FDA would not approve a change to the drug's label to include that warning."227
In PLIVA v. Mensing228 and Mutual Pharmaceutical v. Bartlett,229 the Supreme Court held that similar state claims seeking to strengthen the warnings of generic prescription drugs were preempted. Unlike brand manufacturers who were permitted to add warnings, the Court observed that relevant FDA regulations prohibited the defendant generic manufacturers from "independently changing" a generic drug's label, which must be the same as the reference listed drug.230 Accordingly, the Court concluded—without referencing the presumption against preemption—that it was impossible for the generic manufacturers to both comply with a state tort duty "to change the label" while simultaneously adhering to their "federal-law duty to keep the label the same."231 This conflict, the Court held, was not diminished by the fact that the generic manufacturer could ask FDA for assistance in changing the corresponding brand-name label.232 In Bartlett, the Court further rejected the argument that a generic manufacturer could avoid the conflict by choosing to "stop selling" its product, reasoning that "if the option of ceasing to act defeated a claim of impossibility, impossibility pre-emption would be 'all but meaningless.'"233
Applying Levine, Mensing, and Bartlett, lower courts have also considered whether and to what extent the FD&C Act's premarket approval scheme for prescription drugs preempts state claims alleging that a drug had been defectively designed. In general, courts that have considered design defect claims with respect to generic drugs have held that such claims were preempted under Mensing and Bartlett.234 These courts reasoned that because a generic drug must be "identical in active ingredients, safety, and efficacy" as its reference listed drug, the federal duty of "sameness" made it impossible for a generic manufacturer to simultaneously comply with a state-law duty to change a drug's design.235
Whether design-defect claims against brand manufacturers are preempted is less settled. Lower courts have generally agreed that a state-law claim was preempted if it sought to impose a duty on a brand manufacturer to adopt, post-FDA approval, an alternative design for a drug.236 Such a state-law duty, in the courts' view, "clearly" conflicted with federal law since FDA regulations prohibited a manufacturer from making any major changes to the "'qualitative or quantitative formulation of the drug product, including active ingredients, or in the specifications provided in the approved application.'"237 Courts, however, have disagreed over whether the FD&C Act preempted state claims alleging that relevant state law imposed a duty on a brand manufacturer to adopt a safer alternative design before seeking FDA approval.238 Under this theory, the plaintiffs argued, the state claim was not preempted because "there is no federal law that would have prohibited [the brand manufacturers] from designing a different drug in the first instance."239
In Yates v. Ortho-McNeil-Janssen Pharmaceuticals, Inc., the U.S. Court of Appeals for the Sixth Circuit held that a claim based on a brand manufacturer's pre-approval duty to adopt alternative design was preempted because the claim was premised on a state-law duty that was too speculative, requiring a court to assume that the alternative design would have been approved by FDA.240 Absent a basis for such an assumption, the court concluded that it was "unable to conceive of any coherent pre-approval duty that [the manufacturers] would have owed to [the plaintiff] when it was developing [the drug]," leaving the post-approval duty as the only viable duty, but one that is preempted by FDA regulations restricting major design changes.241
Since Yates, some district courts in other circuits confronting similar claims have disagreed. These courts observe that under Yates, an injured plaintiff "can never bring a defective design claim against a [brand] drug manufacturer."242 This result, in these courts' view, is inconsistent with Levine, which recognized that Congress "determined that widely available state rights of action provided appropriate relief for injured consumers"243 and indicated that "FDA is not the be-all-end-all in drug regulations."244 Congress, in these courts' view, did not intend to shield brand manufacturers from liability "if their drug causes harm due to a defect in design simply because the FDA said the drug was safe."245
Case Law on the Preemptive Scope of Other FD&C Act Prescription Drug Requirements
Other than state tort law claims, a few courts have also considered whether and to what extent the FD&C Act's prescription drug requirements preempt state requirements imposed by state legislatures or agencies.
In Ouellette v. Mills, a district court considered a challenge filed by Maine pharmacists against provisions of a Maine statute that waived certain pharmacy licensure requirements and authorized state residents to receive mail-order prescription drugs for personal use from licensed retail pharmacies located in Canada, the United Kingdom, Australia, or New Zealand.246 Ruling in favor of the pharmacists, the court held that the Maine statute was preempted because it was "contrary to clear Congressional intent to occupy the field of pharmaceutical importation."247
In applying field preemption principles, the Ouellette court concluded—based on legislative history of the state law stating that it was intended to provide residents access to cheaper prescriptions—that the relevant field of regulation was not the field of pharmacist licensure, but the field of "importation of foreign pharmaceuticals."248 Congress, the court observed, had created a complex regulatory scheme covering the importation of pharmaceuticals into the United States under the FD&C Act and has legislated explicitly with respect to the importation of drugs from Canada under FD&C Act section 804.249 In the court's view, these actions evidenced an intent by Congress for the FD&C Act to "occup[y] the field of importation of pharmaceuticals from foreign countries."250 By singling out certain countries from which prescription drugs may be imported, the court concluded, the state law "compromises the tightly regulated structure set up by the [FD&C Act] and the federal government's ability to 'speak with one voice' when it regulates foreign commerce."251
In addition to importation, several courts have also considered whether state laws that restrict access to certain FDA-approved drugs are preempted. In Zogenix, Inc. v. Patrick, a district court examined a Massachusetts emergency order, issued during the opioid crisis, that generally barred the prescribing and dispensing of a then-newly-FDA-approved opioid medication based on concerns about diversion, overdose, and abuse.252 Applying obstacle preemption principles, the district court issued a preliminary injunction against the implementation of the order, holding that the order was preempted by the FD&C Act.253 In the court's view, Massachusetts's ban on the drug was an "obstruction" that undermined FDA's authority to make "drugs available to promote and protect the public health."254 When the state later imposed certain prescribing and dispensing restrictions on the opioid medication short of a ban, the district court conducted a fact-specific analysis to consider the impact of the restrictions and whether they amounted to a de facto ban on the medication.255 The court preliminarily enjoined certain prescribing restrictions because they "would severely frustrate [the medication's] availability," but declined to enjoin other dispensing restrictions because the record did not sufficiently show that the restrictions would cause pharmacies not to carry the drug.256
Several courts have also considered whether the FD&C Act preempts state restrictions on medication abortion. Following the Supreme Court's decision in Dobbs v. Jackson Women's Health Organization, which overruled Roe v. Wade and held that the U.S. Constitution does not confer a right to an abortion,257 numerous states enacted laws aimed at restricting access to abortion, including medication abortion.258 Mifepristone, a drug used in medication abortion, was approved by FDA and subject to a REMS that imposes certain controls over the drug's distribution.259 The most recent REMS, updated in 2023, requires health care professionals who prescribe the drug to be certified; meet specified qualifications (e.g., the ability to assess the duration of a pregnancy accurately); and ensure that patients receive and sign a patient agreement form relating to mifepristone use.260 This version eliminated a prior REMS control that required an in-person office visit to health care providers in specified health care settings,261 allowing patients to obtain the drug through the mail from certified prescribers or pharmacies.262
Lower courts in at least two cases have considered challenges that certain state laws limiting access to medication abortion are preempted by FDA's regulatory controls for mifepristone. In Bryant v. Stein, the court considered a physician's challenge against North Carolina's medication abortion regulations, which included numerous requirements, including an in-person 72-hour advance consultation to review the consent form; use of an ultrasound; blood-type testing; prescription by physicians only; in-person prescribing, dispensing, and administering; and scheduling of an in-person follow-up appointment.263 After closely examining the evolution of FDA's REMS requirements for mifepristone and the nature of the state requirements, the court concluded that some of the state requirements—such as physician-only prescription; in-person prescribing, dispensing, and administering; and an in-person follow-up appointment—"impose[d] safety restrictions on the distribution of [mifepristone]" that FDA had "expressly considered and rejected."264 Accordingly, those state requirements, in the court's view, "stand as an obstacle to the congressional objective of providing a comprehensive regulatory system for the use and distribution of higher-risk drugs under the direction and supervision of the FDA."265 However, the court held that other state requirements—such as the in-person advance consultation, ultrasound, and blood-type testing requirements—were not preempted because they concerned regulation of "general patient health and safety, informed consent to the termination of pregnancy, and regulation of the medical profession," which pertained to issues that were "beyond regulating the safe use of mifepristone."266
In GenBioPro v. Sorsaia, a manufacturer of generic mifepristone challenged certain West Virginia laws that generally prohibit abortion (including access to mifepristone) except under limited circumstances and bar health care providers from prescribing medication abortion drugs via telemedicine.267 Affirming the district court, the U.S. Court of Appeals for the Fourth Circuit (Fourth Circuit), after first determining that the presumption against preemption applied, held that West Virginia's abortion ban as applied to mifepristone use was not preempted by FDA actions that authorized and regulated the sale of the drug.268 In authorizing FDA "to establish minimum safety rules for administering drugs like mifepristone where they may be legally prescribed," the Fourth Circuit reasoned, the FD&C Act's REMS provision "did not create a right to utilize any particular high-risk drug."269 Because the REMS provision did not reflect an intent "to guarantee nationwide access to mifepristone," it was not impossible for the manufacturer to comply with both FDA regulations and the state ban, nor [did] the state ban pose an obstacle to the REMS provision's goal of ensuring drug access.270 The appellate court, however, also noted that the district court's conclusion with respect to the state's separate telemedicine restriction was not at issue in the appeal.271 With respect to the state telemedicine restrictions on mifepristone, the district court held that the restriction was "unambiguously preempted by the 2023 REMS," which "reflects a determination by the FDA that when mifepristone is prescribed, it may be prescribed via telemedicine."272 The state telemedicine restrictions, the courts reasoned, made it impossible for a licensed medical professional prescribing mifepristone to comply "with both the access determination made by the FDA and the access determination made by West Virginia as to telehealth."273
In addition to drugs, the original 1938 FD&C Act also subjected medical devices to FDA regulation. Unlike for new drugs, however, the 1938 law did not authorize FDA to conduct premarket review of new medical devices.274 Instead, FDA's authority over medical devices was primarily limited to seizing or obtaining an injunction against medical devices that were misbranded or adulterated, after the devices were already on the market.275 FDA began to focus its regulatory efforts on medical devices around the 1960s, after developments in the relevant industries—including electronics, plastics, and design engineering—led to the invention of sophisticated devices—such as heart pacemakers, defibrillators, and surgical implants—used to address critical medical conditions.276 After several high-profile reports of safety concerns in the early 1970s related to various devices, including the Dalkon Shield, several cardiac pacemakers, and certain intraocular lenses,277 Congress enacted the Medical Device Amendments of 1976 (MDA).278
The MDA amended the FD&C Act to establish a regulatory regime that oversees medical devices based on the risk posed to the consumer. Specifically, the MDA, as amended, established three classes of devices based on the degree of regulatory control needed to provide assurance of a device's safety and effectiveness. Class I medical devices, considered low risk, are subject to general controls that include manufacturer registration and listing of manufactured devices.279 Class II devices, considered moderate risk, are subject to general controls as well as certain "special controls" deemed necessary by FDA to reduce or mitigate risk.280 Special controls may include, for instance, special labeling requirements, mandatory performance, and post-market surveillance.281 Class III devices are considered the highest risk, because the devices are used to support or sustain human life, are important in preventing impairment of human health, or present a potential, unreasonable risk of illness or injury.282 Class III devices, with certain exceptions, are subject to general controls and premarket approval (PMA) by FDA before they can be lawfully marketed.283
The PMA process is the most stringent approval pathway that FDA can require.284 Under this process, an applicant must submit a PMA application that includes, among other things, information regarding proposed labeling, foreign and U.S. marketing history, summary of clinical and nonclinical studies, conclusions drawn from such studies, and information regarding the components, ingredients, and operating principles of the device.285 After a device has received premarket approval, the manufacturer generally cannot make, without FDA approval, changes to the device—including changes in labeling, indication, performance, or design specifications—that would affect the device's safety or effectiveness.286
The most commonly used premarket approval pathway for medical devices, however, is the premarket notification pathway, commonly referred to as the 510(k) clearance.287 Under this pathway, through which most Class II devices are made available,288 a device manufacturer must submit a 510(k) notification at least 90 days prior to marketing the device.289 The submission must demonstrate that the device proposed to be marketed is substantially equivalent to a certain device already on the market (i.e., a predicate device).290 A device is "substantially equivalent" to a predicate device if it has (1) the same intended use and the same technological characteristics as the predicate device, or (2) the same intended use, different technological characteristics, and information and data that demonstrate safety and effectiveness, and does not "raise different questions of safety and effectiveness than the predicate device."291 So unlike a PMA application, which must include safety and efficacy data concerning the device at issue, a 510(k) submission is focused instead on information comparing the device at issue to a predicate device.292
When Congress enacted the MDA in 1976, at least 13 states had specific statutes or rules regulating medical devices.293 To define the federal and state roles in regulating medical devices, the MDA added an express preemption provision at FD&C Act section 521.294 Subsection (a) of the provision states the following:
[N]o State or political subdivision of a State may establish or continue in effect with respect to a device intended for human use any requirement—
(1) which is different from, or in addition to, any requirement applicable under this chapter to the device, and
(2) which relates to the safety or effectiveness of the device or to any other matter included in a requirement applicable to the device under this chapter.295
Subsection (b) carves out an exception to the scope of preemption under subsection (a). Under subsection (b), FDA may, upon application by a state or its political subdivision, exempt state or local device requirements that are either (1) "more stringent" than federal ones; or (2) "required by compelling local conditions" and where "compliance with the requirement would not cause the device to be in violation of any applicable requirement" under the FD&C Act.296 FDA's implementing regulations related to section 521 also provide that the provision does not extend to "[s]tate or local requirements of general applicability [whose] purpose . . . relates either to other products in addition to devices."297
Courts have evaluated the scope of MDA's express preemption provision on numerous occasions, primarily in the context of considering whether and to what extent the provision preempts state tort law claims alleging manufacturing, design, and/or warning defects related to certain medical devices. In the context of hearing aids, courts have also considered the extent to which the provision preempts state-enacted device requirements.
The Supreme Court has twice considered the scope of the MDA preemption provision (FD&C Act section 521) as applied to state tort law claims, in Medtronic v. Lohr298 and Riegel v. Medtronic.299 In these cases, the Supreme Court generally held that the extent to which section 521 preempts state claims depends in part on how that device received marketing approval from FDA. The Court's reasoning in these cases indicates that the preemptive scope of section 521 is broadest for devices approved through the PMA process, the most rigorous approval pathway, limiting the types of claims a plaintiff may assert based on alleged injuries resulting from the use of such devices.300 The preemptive scope of section 521 for devices cleared through 510(k) notification, on the other hand, is narrower.301
In Lohr, the Supreme Court considered the preemptive scope of section 521 as applied to state claims alleging manufacturing, design, and labeling defects regarding a pacemaker that was cleared for marketing under the 510(k) notification process.302 A majority of the Court agreed that section 521 did not preempt these particular state tort claims, but no majority of Justices agreed on the extent to which the provision preempts state-law tort actions in general.303
In Lohr, the plaintiffs sued a pacemaker manufacturer after a component of the device, implanted in one of the plaintiffs, allegedly failed and caused her to suffer a heart block requiring emergency surgery.304 The plaintiffs asserted various tort claims alleging that the pacemaker was defectively designed and manufactured, and that the manufacturer failed to provide adequate warnings and labels regarding the risk of the device.305 According to the Court, analyzing the preemptive scope of section 521 "require[s] a careful comparison between the allegedly pre-empting federal requirement and the allegedly pre-empted state requirement to determine whether they fall within the intended pre-emptive scope of the statute and regulations."306
The Court held that section 521 did not preempt the plaintiffs' defective design claims because the 510(k) clearance process does not impose federal design requirements related to the "safety" and "effectiveness" of the device.307 Because the 510(k) process merely established that the pacemaker was "substantially equivalent" to a device already on the market, the Court reasoned, FDA "did not 'require' [defendant's] pacemaker to take any particular form for any particular reason," nor did the agency "formally review[]" the device "for safety or efficacy."308 The Court similarly held that the plaintiffs' manufacturing and labeling/warning defect claims were not preempted.309 In the Court's view, "the allegedly pre-empting federal requirement" at issue—certain labeling and "Good Manufacturing Practices" requirements set forth in FDA regulations that are generally applicable to devices and their manufacturers—were not sufficiently specific to the pacemaker to constitute federal requirements "applicable to the device" under section 521 to have preemptive force.310
While a majority of Justices in Lohr agreed that the plaintiffs' state-law tort claims were not preempted under section 521, a different majority of Justices also expressly indicated that "the MDA will sometimes preempt a state-law tort suit."311 This open question regarding the circumstances under which state-law tort claims are preempted led to continued litigation in the lower courts.
In Riegel v. Medtronic, the Supreme Court resolved some aspects of the open questions when it held that certain state-law tort claims based on alleged injuries related to a medical device approved through the PMA process were preempted under section 521. In Riegel, the plaintiffs sued a catheter manufacturer after the catheter, used in a coronary angioplasty procedure for one of the plaintiffs, ruptured during the procedure and caused the patient to develop a heart block, requiring emergency coronary bypass surgery.312 The plaintiffs alleged that the catheter was defectively designed, labeled, and manufactured in a manner that violated applicable state common law.313 Siding with the defendant, the Court affirmed the dismissal of the plaintiffs' claims as preempted.314
In reaching this conclusion, the Court first concluded that the PMA process—unlike the 510(k) notification process and the generally applicable labeling and manufacturing requirements at issue in Lohr—imposes device-specific federal requirements.315 Unlike the 510(k) notification process—which focuses on a device's substantial equivalence to an already marketed device and does not require a device to "take any particular form for any particular reason"—the PMA process, the Court observed, "is federal safety review."316 Under the PMA process, an approved device must "be made with almost no deviations from the specifications in its approval application, for the reason that the FDA has determined that the approved form provides a reasonable assurance of safety and effectiveness."317 The Court then held that a state's "requirements" subject to preemption under section 521 "include[] its common-law duties."318 In so concluding, the Court rejected the plaintiffs' argument that section 521 "exclud[es] common-law duties from the scope of pre-emption" and preempts only state regulatory law or state requirements specific to the device.319 Accordingly, because the plaintiffs asserted that the catheter device "violated state tort law notwithstanding compliance with the relevant federal requirements"—such that the applicable common law duties imposed requirements beyond federal requirements—the Court held that their state claims were preempted.320
At the same time, the Court acknowledged that section 521 does not preempt all state claims related to a device approved under the PMA process.321 Specifically, the Court observed that even if state common-law duties impose relevant state safety and efficacy "requirements," they are preempted under section 521 "only to the extent that they are 'different from, or in addition to' the requirements imposed by federal law."322 In other words, state requirements that "parallel" federal requirements are not preempted.323 In Riegel, however, the Court observed that because the plaintiffs did not argue that they had asserted parallel state claims, it declined to consider, in the first instance, whether the plaintiffs had raised parallel claims, and affirmed the dismissal of their claims.324
Following Riegel, lower courts have generally concluded that for devices approved through the PMA process, Riegel, combined with the Court's decision in Buckman,325 leave a "'narrow gap' through which a state-law claim must fit to escape preemption by the [FD&C Act]."326 In general, lower courts have held that state-law claims related to PMA-approved devices avoid preemption only if they rest on a state-law duty that parallels a federal-law duty.327 As a practical matter, this means that many design or manufacturing defect claims—to the extent that they assert that a PMA-approved device should have been designed or manufactured differently from the specifications FDA had approved—are preempted.328 Some parallel state claims, however, have been found to escape preemption. For example, several courts have concluded that certain state-law failure-to-warn claims were not preempted to the extent that they alleged that a defendant failed to report serious injuries and malfunctions of the device as required by both applicable FDA regulations and applicable state tort law duty to provide "adequate warnings or instructions."329
In addition to cases that considered the preemptive scope of FD&C Act section 521 as applied to state tort claims, several lower courts have also considered section 521 as applied to device-specific requirements enacted by states, particularly with respect to hearing aids.330
At least one state, for example, had sought to invoke the preemption exemption process under section 521(b) for the state's hearing aid requirements. Specifically, in 1978, Massachusetts enacted a state law regulating the sale of hearings aids in that state.331 The state requirements were more stringent than the then-applicable FDA hearing-aid regulations in two respects: (1) the state law required all consumers—with the exception of those with a religious waiver—to obtain a medical evaluation from a physician before purchasing a hearing aid, while FDA regulations generally permitted adults who had been provided with specified warnings to waive the medical evaluation requirement; and (2) the state law, unlike the FDA regulations, also required a "hearing test evaluation" by a physician or audiologist.332 After FDA denied Massachusetts's application for exemption following a public hearing and receipt of comments, the state sued to challenge the denial.333 The U.S. Court of Appeals for the First Circuit, in Massachusetts v. Hayes, upheld FDA's denial of exemption.334 In doing so, the court rejected the state's argument that section 521(b) required FDA to grant an exemption "whenever state regulations are 'more stringent' and do not unduly burden interstate commerce."335 In the court's view, FDA's "statutory authority to grant exemption from preemption is plainly discretionary."336 The court further concluded that FDA's denial of exemption was not arbitrary and capricious, given the agency's review of evidence related to the predictive value of audiological testing and its conclusion that "audiological evaluation is not necessary to provide reasonable assurance of the safety or effectiveness of hearing aids."337
For state hearing aid requirements not subject to exemption from preemption, several courts have considered the extent to which they were preempted by section 521(a). Several courts have held, for instance, that state laws which required hearing aid purchasers to undergo presale "fitting and testing" services by specified licensed professionals were preempted by then-applicable federal regulations.338 In the courts' view, because applicable federal regulations generally required purchasers to undergo an auditory evaluation or provide a signed waiver, an auditory examination was effectively optional; thus, a state law requiring presale fitting and testing imposed a safety and efficacy requirement "in addition to" federal requirements and was preempted.339 In contrast, another court held that a state's general licensure requirements for hearing aid dispensers, which were not tied to the state's separate pre-sale testing requirements, were not expressly preempted by section 521(a).340
The FD&C Act, since its initial enactment in 1938, prohibits the marketing of adulterated or misbranded cosmetics (i.e., cosmetics that are unsafe or mislabeled).341 A cosmetic is deemed adulterated, for instance, if it contains any substances that are poisonous, putrid, or unsanitary, or otherwise contain a "substance which may render it injurious to users."342 A cosmetic is deemed misbranded, for instance, if its "labeling is false or misleading in any particular."343 In 1966, Congress enacted the Fair Packaging and Labeling Act (FPLA), which authorized FDA to issue regulations governing the labeling and packaging of many cosmetic products.344 In 1970, Congress additionally enacted the Poison Prevention Packaging Act of 1970 (PPPA) to require special packaging to protect children from injury or illness from handling or ingesting household substances, including cosmetics.345 Cosmetic products that do not comply with FPLA and PPPA requirements are deemed misbranded under the FD&C Act.346 These authorities governing cosmetics, which generally do not need to undergo premarket review,347 remained largely unchanged until Congress enacted the Modernization of Cosmetics Regulation Act of 2022 (MoCRA).348 MoCRA expanded FDA's regulatory authority over cosmetics in several respects. While cosmetic products generally still are not subject to premarket review, MoCRA requires cosmetics manufacturers to report serious adverse events, register their facilities and list cosmetic products with FDA, and substantiate the safety of their products.349 MoCRA also expanded the labeling requirements for cosmetics, including requiring product labels to identify each fragrance allergen contained in the product.350
With respect to cosmetics, the FD&C Act contains two express preemption clauses that reflect Congress's recognition of states' concurrent role in regulating these products. FD&C Act section 752, enacted in 1997, states the following:
[N]o State . . . may establish or continue in effect any requirement for labeling or packaging of a cosmetic that is different from or in addition to, or that is otherwise not identical with, a requirement specifically applicable to a particular cosmetic or class of cosmetics under [the FD&C Act], the Poison Prevention Packaging Act of 1970 . . . , or the Fair Packaging and Labeling Act . . . .351
At the same time, section 752(d) specifically states that this preemption clause "shall [not] be construed to modify or otherwise affect any action or the liability of any person under the product liability law of any State."352 Section 752(e) further states that the section does not "apply to a State requirement adopted by a State public initiative or referendum enacted prior to September 1, 1997."353
In 2022, MoCRA added a second preemption clause at FD&C Act section 614. The provision states, in relevant part, the following:
No State . . . may establish or continue in effect any law, regulation, order, or other requirement for cosmetics that is different from or in addition to, or otherwise not identical with, any requirement applicable under [the FD&C Act] with respect to registration and product listing, good manufacturing practice, records, recalls, adverse event reporting, or safety substantiation.354
Section 614 also explicitly preserves state laws in several respects. To preserve state regulation of cosmetic ingredients, the provision clarifies that section 614 should not be "construed to prevent any State from prohibiting the use or limiting the amount of an ingredient in a cosmetic product," nor should section 614 be construed to prohibit a state from continuing in effect any state requirement that directed the reporting of a cosmetic ingredient to the state that was in effect at the time of MoCRA's enactment.355 In addition, section 614 includes a savings clause stating that no MoCRA provision or any of its implementing regulations "shall be construed to modify, preempt, or displace any action for damages or the liability of any person under the law of any State, whether statutory or based in common law."356
To date, courts that have considered the preemptive scope of the FD&C Act's cosmetics provisions appear to have addressed only the preemptive scope of FD&C Act section 752.357 In these cases, the plaintiffs' claims generally involved state-law claims alleging that a cosmetic product's label was misleading or did not adequately warn of the risks associated with the product.358
When considering whether these claims were preempted, courts have generally held that state-law claims interpreted to impose labeling requirements identical to those required by the FD&C Act were not preempted by section 752.359 For example, in Astiana v. Hain Celestial Group, the plaintiffs brought claims under California's unfair competition and false advertising laws and for common law fraud alleging that a cosmetic labeled "all natural" or "pure natural" duped consumers seeking natural products into buying products that were full of artificial and synthetic ingredients.360 The court considered whether the state-law claims imposed a requirement that was "different from or in addition to, or that is otherwise not identical with" a cosmetics requirement in the FD&C Act.361 The court concluded that they did not.362 If the label stating the product was "all natural" and "pure natural" was misleading as the plaintiffs claimed, the court reasoned, it would also violate the FD&C Act, which prohibits cosmetic labeling that is "false or misleading in any particular."363 The Ninth Circuit therefore held that the plaintiffs' claims were not preempted because they would impose requirements identical to those imposed by the FD&C Act.364
On the other hand, courts have concluded that certain state claims that sought to add additional disclaimers not required by applicable federal requirements were preempted.365 In Critcher v. L'Oreal USA, Inc., consumers who had purchased liquid cosmetic products alleged that they were unable to dispense a portion of the product from the containers.366 They asserted state-law claims based on allegations that they were duped "into buying more of the cosmetics than they could use" and that the product labels should have disclosed that the products could not be fully dispensed from their containers.367 The plaintiffs, however, conceded that the packaging complied with federal packaging requirements and that the labels accurately stated the amount of product contained in each package.368 The U.S. Court of Appeals for the Second Circuit held that the plaintiffs' claims were preempted because the FD&C Act does not impose obligations to include supplemental disclosures regarding the amount of accessible product, which would impose labeling requirements "in addition to" those mandated by the FD&C Act.369
The original 1938 FD&C Act did not expressly authorize FDA to regulate tobacco products. Before 1996, FDA generally took the position that it lacked jurisdiction under the FD&C Act to regulate tobacco products.370 As evidence of tobacco manufacturers' knowledge regarding the health effects of their products mounted,371 however, FDA promulgated a final rule in 1996 that would have imposed several restrictions on the sale, distribution, and advertisement of tobacco products.372 FDA asserted that it had jurisdiction to regulate tobacco products based on its determination "that nicotine is a 'drug' and that cigarettes and smokeless tobacco are 'drug delivery devices[.]'"373 A group of tobacco manufacturers, retailers, and advertisers sued to challenge the rule.374 In 2000, the Supreme Court held in FDA v. Brown & Williamson Tobacco Corp. that "[c]onsidering the [FD&C Act] as a whole, it is clear that Congress intended to exclude tobacco products from the FDA's jurisdiction."375 In the Court's view, under the FD&C Act's regulatory regime, "FDA may not . . . conclude that a drug or device cannot be used safely for any therapeutic purpose and yet, at the same time, allow that product to remain on the market,"376 yet Congress had "foreclosed the removal of tobacco products from the market" in other tobacco-specific legislation.377 Given that tobacco products "cannot be used safely for any therapeutic purpose [yet] they cannot be banned," the Court reasoned that these products "simply d[id] not fit" within the FD&C Act's regulatory scheme.378
In 2009, Congress enacted the Family Smoking Prevention and Tobacco Control Act (TCA), which amended the FD&C Act to expressly authorize FDA to regulate tobacco products as a category separate from food, drug, devices, and cosmetics.379 The TCA establishes the central federal regulatory regime for the manufacture, marketing, and distribution of tobacco products.380 In establishing this regulatory regime, the TCA aims to balance competing interests in protecting the public's health against the harmful effects of smoking and youth tobacco use, while preserving access to lawfully marketed tobacco products for adult consumers.381
Among other requirements, the TCA requires all new tobacco products—i.e., those not commercially marketed in the United States prior to February 15, 2007—to receive prior authorization from FDA before being marketed to the public.382 In particular, the TCA requires FDA to deny an application seeking authorization for a new tobacco product if the agency finds that "there is a lack of a showing that permitting such tobacco product to be marketed would be appropriate for the protection of the public health."383 In addition, the TCA, based on Congress's recognition that flavors can make tobacco products more appealing to youth and expose users to additional carcinogens or other toxic constituents,384 also expressly prohibits the manufacture and sale of cigarettes or cigarette components with flavors other than tobacco or menthol.385 The same provision, at FD&C Act section 907(b), further authorizes FDA to adopt, through notice-and-comment rulemaking, additional tobacco product standards if the agency finds that such a standard "is appropriate for the protection of the public health."386 FDA may also promulgate restrictions on the sale and distribution of a tobacco product—including restrictions on the access to, and the advertising and promotion of, the tobacco product.387 Additionally, the TCA imposes certain labeling requirements388 on top of those already required under then-existing federal law.389
While the TCA explicitly applies to cigarettes, cigarette tobacco, roll-your-own tobacco, and smokeless tobacco, the statute also authorizes FDA to deem other tobacco products subject to the law.390 In 2016, FDA invoked this authority and promulgated what is known as the Deeming Rule, which subjected certain electronic nicotine delivery system products—products commonly known as e-cigarettes or vapes—to the TCA's regulatory regime.391 Under the rule, entities seeking to legally market their e-cigarettes that were on the market as of August 8, 2016, or any new e-cigarette products, were generally required to submit a premarket tobacco product application and receive marketing authorization from FDA.392
As of the date of this report, FDA has authorized 35 tobacco-flavored e-cigarettes and 6 menthol-flavored e-cigarettes for lawful marketing.393 With respect to those products, the agency generally concluded that they were "appropriate for the protection of public health" because they can benefit adult smokers by helping them switch to less harmful tobacco products.394 FDA has not authorized any dessert-, candy-, or fruit-flavored (sweet-flavored) e-cigarettes for lawful marketing. According to FDA, the applications for such products to date "lacked sufficient evidence that the benefit to adult smokers who used the flavor products would overcome the public health concern posed by the well-documented and considerable appeal of the products to youth."395
The TCA also included a provision, at FD&C Act section 916, that addresses the interaction of federal and state/local laws. Prior to the TCA's enactment in 2009, federal laws regulating tobacco products were primarily focused on certain labeling requirements and advertising restrictions for certain tobacco products.396 Accordingly, before 2009, states and localities played a key role in regulating the sale and use of tobacco products within their respective jurisdictions. For instance, states and localities, to varying degrees, mandated smoke-free indoor and outdoor spaces,397 prohibited the sales of cigarettes in vending machines and near schools,398 and imposed excise taxes on tobacco products.399 Section 916, entitled "Preservation of State and local authority," addresses the interaction of the TCA and relevant state and local laws in three parts.400
The first part of section 916, at subsection (a)(1), is often referred to as the preservation clause.401 It generally states that, subject to the preemption clause at subsection (a)(2)(A), nothing in the TCA and its implementing rules shall be construed to limit the authority of a federal agency, state, locality, or tribe to enact or promulgate "any law, rule, regulation, or other measure with respect to tobacco products that is in addition to, or more stringent than, requirements established under [the TCA]."402 Subsection (a) specifies that such additional requirements include those "relating to or prohibiting the sale, distribution, possession, exposure to, access to, advertising and promotion of, or use of tobacco products by individuals of any age, information reporting to the State, or measures relating to fire safety standards for tobacco products."403
The second part of section 916, at subsection (a)(1)(A), is a preemption clause.404 It states that
No State or political subdivision of a State may establish or continue in effect with respect to a tobacco product any requirement which is different from, or in addition to, any requirement under the provisions of [the TCA] relating to tobacco product standards, premarket review, adulteration, misbranding, labeling, registration, good manufacturing standards, or modified risk tobacco products.405
The third part of section 916, at subsection (a)(1)(B), is a savings clause that qualifies the preemption clause.406 It states that the preemption clause "does not apply to requirements relating to the sale, distribution, possession, information reporting to the State, exposure to, access to, the advertising and promotion of, or use of, tobacco products by individuals of any age, or relating to fire safety standards for tobacco products."407
Section 916(b) clarifies that "no provision of [the TCA] relating to a tobacco product shall be construed to modify or otherwise affect any action or the liability of any person under the product liability law of any State."408
As states and localities continue to play a role in the regulation of tobacco products, lower courts have considered the preemptive scope of FD&C Act section 916 on several occasions, primarily in the context of e-cigarette regulation. Even though no sweet-flavored e-cigarettes have received FDA authorization for lawful marketing to date, such products continue to be widely available.409 To address the availability of unauthorized flavored e-cigarettes, some states and localities have, for instance, restricted or banned the sale of such products within their jurisdictions.410 In addition, state and local governments, consumers, and/or competing e-cigarette manufacturers have also sued certain e-cigarette manufacturers and other defendants, alleging that the defendants, in violation of applicable state unfair or deceptive acts or other related laws, unlawfully marketed or distributed certain unauthorized or defectively designed e-cigarettes, or engaged in a false and deceptive marketing campaign related to certain e-cigarettes.411 Several lower courts have considered the preemptive scope of section 916 as applied to local ordinances that restricted or banned the sale of all flavored e-cigarettes and to state consumer protection or tort law claims.
Case Law on the Preemptive Scope of FD&C Act Section 916 As Applied to Local Ordinances Restricting Sale of Flavored E-Cigarettes
At least three appellate courts have considered whether FD&C Act section 916 preempts local ordinances that restrict or ban the sale of flavored e-cigarettes (i.e., sweet- or menthol-flavored e-cigarettes) within the relevant locality.412 In each case, the relevant ordinance either limited the sale of such products to specially licensed establishments (i.e., tobacco bars) or banned their sale altogether.413 In response, affected e-cigarette manufacturers filed suits to challenge the ordinances, arguing that the applicable sales restriction or ban was preempted by section 916 because the flavor restriction or ban constituted a "tobacco product standard[]" and imposed a requirement "different from, or in addition to" federal requirements.414 In each case, the court held that section 916's preemption clause did not expressly preempt the relevant sales restriction or ban, and that even if the sales restriction or ban were subject to the preemption clause, they were saved from preemption under the savings clause.415
In these cases, the courts generally recognized section 916 to be composed of three parts. The first part, the preservation clause, generally "broadly preserves state, local, and tribal power to enact any regulation concerning tobacco products that is 'in addition to or more stringent' than those promulgated by the TCA."416 The preemption clause, according to these courts, immediately follows the preservation clause to carve out certain exceptions or define its limits.417 Relevant to the ordinances restricting or banning the sale of flavored e-cigarettes is the preemption clause's limit that "[n]o State or political subdivision of a State may establish . . . with respect to a tobacco product any requirement which is different from, or in addition to, any requirement under [TCA] relating to tobacco product standards."418 These courts held that the applicable sales restriction or ban did not constitute a product standard subject to preemption because those standards "pertain[] to the production or marketing stages up until the actual point of sale."419 In the courts' view, "[a] local sales regulation"—which operates on a finished product and "does not clearly infringe on the FDA's authority to determine what chemicals and processes may be used in making tobacco product"—"is therefore not preempted."420
The courts, however, also recognized that "[t]he line between regulating the sale of a finished product and establishing product standards will not always be easy to draw."421 "'Flavored tobacco products,'" one court observed as an example, "can arguably be described either as a category of finished product or as products that are manufactured with ingredients that impart a flavor."422 Accordingly, these courts further held that even if the ordinances were construed as establishing a tobacco product standard subject to preemption, they were "saved" from preemption by the savings clause, which "except[s] . . . from preemption . . . 'requirements relating to the sale . . . of[] tobacco products [to] individuals of any age.'"423 The savings clause, according to the courts, reinforces what is first established in the preservation clause—"that the regulation and prohibition of tobacco product sales falls squarely within the purview of states, localities, and tribal entities."424 In the courts' view, section 916's three-part structure "reserves regulation at the manufacturing stage exclusively to the federal government, but allows states and localities to continue to regulate sales and other consumer-related aspects of the industry in the absence of conflicting federal regulation."425
Case Law on the Preemptive Scope of FD&C Act Section 916 As Applied to State Tort and Consumer Protection Law Claims
Local governmental entities, as well as certain consumers and other private parties, have also filed suit against certain e-cigarette manufacturers, often alleging claims based on state consumer protection and/or tort laws. These suits have alleged, for instance, that the defendant e-cigarette manufactures, in violation of state consumer protection laws, marketed certain unauthorized e-cigarettes, or engaged in certain misleading or deceptive conduct—including through product designs that appealed to youth and statements on product labels and websites—with respect to certain e-cigarettes.426 Some suits have also alleged that the defendant e-cigarette manufacturers failed to adequately warn of the products' risks in violation of state tort laws.427 In response, the defendant e-cigarette manufacturers have argued that such claims were preempted by FD&C Act section 916.428 With the exception of certain claims based on product labeling, lower courts that have considered the preemption question have generally held that section 916 did not preempt these state-law claims.429
In In re: JUUL Labs, Inc., Marketing, Sales Practices, and Products Liability Litigation, for instance, a county government, several school districts, and certain consumers sued an e-cigarette manufacturer and its distributors and retailers, alleging that the defendants violated applicable state consumer protection and products liability laws.430 In particular, the plaintiffs alleged that the manufacturer defendant designed its e-cigarettes to maximize addiction and to appeal to youth while further promoting the products, with the assistance of the distributor and retailer defendants, by targeting youths.431 Among other claims, the plaintiffs alleged that (1) the manufacturer defectively designed their e-cigarettes in its choice of the products' nicotine yields, ingredients, and flavorings as well as their "sleek easily concealable design"; (2) the manufacturer defendant provided misleading or inadequate warnings on its product labels by failing to disclose the greater addictiveness of its products; and (3) the defendants engaged in false and misleading advertising of the manufacturer's e-cigarettes by promoting the products as "a fun and safe alternative to cigarettes that would help smokers quit."432 In response to defendants' argument that these claims were expressly preempted by section 916, the court held that only the plaintiffs' labeling claims based on inadequate disclosures regarding nicotine addiction were preempted, given that FDA had specified the precise language and placement of the nicotine warning label.433 The other claims, the court reasoned, were not expressly preempted because FDA had not yet promulgated "any actual design or product standards for [e-cigarettes]"434 and section 916's exception clause under subsection (a)(2)(B) expressly "preserves state requirements regarding the 'exposure to, access to, the advertising and promotion of, or use of, tobacco products.'"435
Similarly, in NJOY, LLC v. Imiracle (HK) Ltd., an e-cigarette manufacturer with products authorized by FDA sued its competitors and their retailers for violations of the applicable state consumer protection law.436 The plaintiff alleged that the defendants unlawfully sold unauthorized flavored e-cigarettes and deceptively marketed those products—including through packaging, labels, and website representations—as lawful.437 In response to defendants' argument that the plaintiff's claims were preempted, the court held that plaintiff's claims were preempted to the extent they were based on "deficiencies in the inclusion or omission of information on [the e-cigarettes'] labels."438 In the court's view, such claims imposed "additional or different labeling requirements" than what FDA requires.439 At the same time, the court held that the plaintiff's claims were not preempted to the extent they "relie[d] on conduct or practices unrelated to labeling," including claims related to misleading website representations and violations of the state's ban of flavored e-cigarettes.440
Both Congress's amendments of the FD&C Act over the years addressing preemption and the courts' jurisprudence on FD&C Act preemption reflect the recognition of states' long-standing role in concurrently regulating the products subject to the FD&C Act.
Congress has chosen to include express preemption provisions for some FD&C Act product-specific provisions but not others. Until the Medical Device Amendments of 1976 (MDA), the FD&C Act did not include provisions that expressly preempt state law.441 The FD&C Act's prescription drug provisions—which set up the earliest regulatory framework for premarket review of a product in the original 1938 FD&C Act—still does not include an express preemption provision.442 Where Congress has included express preemption provisions, their scope is generally tethered to the scope of the applicable federal regulation. For instance, when the MDA subjected certain medical devices to premarket review by FDA for safety and efficacy, the express preemption provision (FD&C Act section 521) preempts state laws that impose different or additional safety and effectiveness requirements.443 For food and cosmetic products subject to federal labeling requirements, the applicable express preemption provisions preempt non-identical labeling requirements to promote national uniformity in labeling.444 Depending on the relevant status of state regulation, Congress sometimes further calibrated the scope of preemption to specifically preserve certain application of state law. FD&C Act section 916, which addresses the interaction of federal and state law for tobacco products, for instance, sandwiched the express preemption provision between both a preservation clause and a savings clause that qualify the express preemption clause by preserving certain state requirements, including those relating to the sale and promotion, or use, of tobacco products by individuals of any age.445
The courts' FD&C Act preemption jurisprudence reflects a similar recognition of states' role in the regulation of these products. With the exception of a particular type of fraud claim that the Supreme Court has found to be impliedly preempted by the FD&C Act's general enforcement scheme,446 courts considering FD&C Act preemption questions frequently undertake a case-specific, often granular, comparative analysis of what federal law requires or permits and whether and to what extent the relevant state requirements conflict with federal requirements.447 The case law indicates that courts may be especially reluctant to find the existence of a conflict where Congress has not spoken directly with respect to preemption.448 For instance, with respect to brand prescription drugs, the Supreme Court in Wyeth v Levine, relying in part on the presumption against preemption, rejected the argument that state-law claims seeking to strengthen a brand-name drug's risk warnings are generally preempted, even though such warnings are subject to FDA regulatory requirements.449 Instead, the court held that such failure-to-warn claims may survive preemption as long as there was no "clear evidence that FDA would not have approved."450 In addition, although courts appear to generally agree that the premarket approval scheme preempts state-law claims seeking to impose an alternative design for drugs post-approval, some lower courts have held that not all design defect claims against brand-name drugs are necessarily preempted by the fact of FDA approval.451 At the same time, in at least one discrete instance, a lower court interpreted the FD&C Act's prescription drug provisions to have broader preemptive scope with respect to drug importation—an aspect of drug regulation not historically subject to state regulation.452
Where Congress has included express preemption provisions in the FD&C Act, courts have typically interpreted the provisions' preemption of "additional," "different," or "non-identical" state requirements addressing particular areas subject to federal regulation to mean that state laws or claims seeking to impose requirements that parallel federal requirements are not preempted.453 Here, too, courts often analyze the state requirements a plaintiff seeks to impose, the applicable federal requirements and their degree of regulation, and whether the state requirements may be construed to impose identical obligations as federal regulations.454 As interpreted by courts to date, even the MDA's express preemption provision for medical devices—arguably the broadest preemption provision discussed in this report—has not been interpreted to preempt all state claims asserted against a medical device subject to the most stringent form of premarket review.455 Where a case raises difficult preemption questions, courts have also explicitly looked to historical regulatory roles of the states on a topic to parse a carefully calibrated express preemption provision.456 These nuanced analyses often lead to few bright-line results and the preservation of at least some state requirements at issue in a particular case.457
The case law on FD&C Act preemption suggests that courts may be likely to give effect to state requirements where possible, particularly given courts' recognition of states' long-standing role in the regulation of products subject to the FD&C Act. State requirements may be most likely to survive preemption where Congress is silent on the interaction of federal and state law. Existing express preemption provisions have also been interpreted to leave room for certain state requirements. At the same time, there is some indication that courts may be more likely to construe relevant FD&C Act provisions to have broader preemptive effect on certain aspects of product regulation that is not historically regulated by states. These considerations may inform Congress's decision on whether to modify existing express preemption provision, add additional express preemption provisions, and consider the appropriate degree of specificity of any such provisions.

State tort law originates in common law and provides a mechanism, through case-by-case litigation, for a person injured by the wrongful or injurious actions of another to recover damages. Products liability is a subset of tort law that permits a plaintiff injured by a defective product to recover damages from the manufacturer of that product.

Other products subject to FDA regulation include other subcategories of food and drug products—such as dietary supplements (which are a subset of "food" under the FD&C Act), over-the-counter drugs, and animal drugs—as well as biological products. See 21 U.S.C. §§ 343(s), 355h, 360b; 42 U.S.C. § 262. Biological products, or biologics, are a diverse category of products (including vaccines and blood products) used to diagnose, prevent, and treat diseases and conditions; they are made from living organisms and are generally large, complex molecules. See 42 U.S.C. § 264(i)(1); see also CRS Report R44620, Biologics and Biosimilars: Background and Key Issues, by Hassan Z. Sheikh (2019). Unlike other FDA-regulated products, biological products are subject to the Public Health Service Act (PHSA) rather than the FD&C Act, but the relevant PHSA provisions incorporate by reference many FD&C Act provisions that apply to prescription drugs. See, e.g., 42 U.S.C. §§ 262(a)(2)(B); 262(a)(2)(D); 262(h); 262(j). A discussion of the preemption jurisprudence pertaining to these other products is beyond the scope of this report. |

To the extent some Justices have cast doubt over obstacle preemption in general, as discussed above, such doubt raises a potential question as to Buckman's validity, should the Supreme Court revisit its obstacle preemption jurisprudence. However, even if the Supreme Court reconsiders its obstacle preemption jurisprudence, any narrowing or elimination of the obstacle preemption doctrine may not end the preemption analysis in a given case. Other relevant FD&C Act provisions may have preemptive effect under other preemption principles. In Buckman, for instance, a lower court concluded that the state claims were also preempted by the express preemption provision that applies to medical devices. See 531 U.S. 341 at 347. |

21 U.S.C. § 343(g). |
| 110. |
Id. § 341; 21 C.F.R. §§ 131.3–169.182 (2025) (standard of identity regulations). The FD&C Act directs FDA to promulgate standards of identity whenever "such action will promote honesty and fair dealing in the interest of consumers." 21 U.S.C. § 341. |

Id. § 101.72. The FD&C Act also imposes requirements on health claims, which are claims that link the consumption of a nutrient to a disease or health-related condition. 21 U.S.C. § 343(r)(1)(B). For example, a label for a product that is high in calcium (such as milk) may state that consuming the product may reduce the risk of osteoporosis. 21 C.F.R. § 101.72 (2025). The FD&C Act allows a manufacturer to include a health claim on a food's label only when FDA has promulgated a regulation approving the health claim, based on a determination that there is "significant scientific agreement" among qualified experts that the claim is supported. 21 U.S.C. § 343(r). To date, FDA has promulgated regulations approving 12 health claims. See 21 C.F.R §§ 101.72–101.83 (2025). FDA has also opted to exercise enforcement discretion to allow the use of certain so called "qualified health claims" that do not meet the statutory criteria with the use of an appropriate disclaimer. See Guidance for Industry: FDA's Implementation of Qualified Health Claims: May 2006, FDA (Sep. 20, 2018), https://www.fda.gov/regulatory-information/search-fda-guidance-documents/guidance-industry-fdas-implementation-qualified-health-claims [https://perma.cc/Z6TZ-N523]. |

The FDA's standard of identity . . . does not demand a warning about dental fluorosis." (quoting 21 C.F.R. § 100.1(c)(4)). |

Hawkins v. Kroger Co., 906 F.3d 763, 767, 773 (9th Cir. 2018). |

Id. at 770 (internal quotations omitted). See also id. ("'Information that is required or permitted by § 101.9 . . . and that appears as part of the nutrition label, is not a nutrient content claim . . . . If such information is declared elsewhere on the label . . . it is a nutrient content claim and is subject to the requirements for [such] claims.'" (alteration in original) (quoting 21 C.F.R. § 101.13(c))). Unlike in Pardini, in which a challenged nutrient content claim on the front label was explicitly permitted by applicable FDA regulation, see 21 C.F.R. § 101.62(b), the challenged nutrient content claim in Hawkins was not subject to applicable FDA regulation.

See Bell, 982 F.3d at 483–84. |

Id. The court noted that the NLEA preemption clause does not include the FD&C Act's general prohibition of "false or misleading" labeling, and therefore the preemption clause "does not expressly preempt state-law prohibitions on deceptive statements that sellers add voluntarily to their labels or advertising." Id. (quoting 21 U.S.C. § 343(a)). |
| 168. |
Id. at 485. The court also briefly addressed the argument that the FD&C Act impliedly preempted the plaintiff's claims, concluding that impossibility preemption did not apply because it was possible to comply with applicable state and federal requirements. Id. at 486. |

Marrache, 17 F.4th at 1092–97. At least one other court has considered a challenge of another state law restricting the use of certain substances in food. In International Ass'n of Color Manufacturers v. Singh, the district court considered a West Virginia law banning "'any added substance or ingredients which are poisonous or injurious to the health'" including several color additives. No. 2:25-cv-00588, 2025 WL 3721864, at *2 (S.D.W. Va. Dec. 23, 2025) (quoting W. Va. Code § 16-7-2(b)(7)). The court preliminarily enjoined the state from enforcing the law after determining that the plaintiff was likely to succeed on the merits of its claim that the phrase "poisonous or injurious to the health" is "unconstitutionally vague" and "leaves the door open for arbitrary enforcement." See id. at *10–11. The plaintiff in Singh did not argue that the West Virginia ban was preempted by the FD&C Act. See id. at *3–12. |

The Drug Amendments of 1962 included a provision stating that "[n]othing in the amendments made by this Act . . . shall be construed as invalidating any provision of State law . . . unless there is a direct and positive conflict between such amendments and such provision of State law." Pub. L. No. 87-781, § 202, 76 Stat. 780, 793. In Wyeth v. Levine, the Supreme Court described this provision as a "saving clause" and observed that "when Congress enacted an express pre-emption for medical devices in 1976, it declined to enact such a provision for prescription drugs." 555 U.S. 555, 567 (2009) (citations omitted)). |

FDA regulations governing hearing aids changed significantly after the agency, pursuant to section 709 of the FDA Reauthorization Act of 2017, Pub. L.

(citation omitted) (quoting 21 U.S.C. § 379s(a))). Lower courts have also grappled with how to interpret FD&C Act section 752's savings clause that explicitly preserves state products liability claims. In at least one case, the court held that the plaintiffs' non-products-liability claims (e.g., negligent misrepresentation and breach of warranty claims) were not preempted, to the extent they were based on the same allegations as plaintiffs' products liability claims.

U.S. Smokeless Tobacco Mfg. Co., 708 F.3d at 434. See also Cnty. of L.A., 29 F.4th at 555 (stating that section 916's three-part structure "reveals a careful balance of power between federal authority and state, local, and tribal authority, whereby Congress has allowed the federal government to set the standards regarding how a product would be manufactured and marketed, but has left states, localities, and tribal entities the ability to restrict or opt out of that market altogether"); City of Edina, 60 F.4th at 1177 (holding that interpreting the ordinance to be "rescued by the Savings Clause" is a result compelled by the federalism canon because the ordinance implicated the states' traditional police powers to protect public health and safety, which has been invoked by state and local authorities to enact "public health measures directed at the dangers of tobacco use" since the early 1900s). |
