Defense Primer: Acquiring Specialty Metals and Sensitive Materials
Some metals and metal alloys, as well as strong permanent magnets known as rare earth magnets, are critical to U.S. Department of Defense (DOD) operations. These are frequently integrated into components (e.g., integrated circuits, electrical wiring, or optoelectronic devices) or structures (e.g., aircraft fuselages or ship hulls) of numerous military platforms and weapon systems. There are few, and, in some cases, no known alternatives for these materials, which often have unique physical properties (such as high material strength coupled with resistance to corrosion or low density). In addition, the existing sources for many of these are very limited and, sometimes, located in adversarial countries. As a result, Congress has established sourcing requirements and restrictions relating to specialty metals and other sensitive materials, that may ensure continued or expanded U.S. access for defense purposes.
A rare earth element is one of 17 chemical elements, including the 15 metallic chemical elements with atomic numbers 57 through 71, as well as the chemically similar elements scandium and yttrium. These materials are considered rare in spite of their relative abundance throughout the Earth’s crust, as the extraction and production of such materials can be difficult and costly. Rare earth magnets produced using rare earth elements are the strongest known permanent magnets.
Title 10 §4863 United States Code requires that some items that incorporate certain metals and metal alloys (i.e., specialty metals) generally be produced or manufactured in the United States. Other statutory prohibitions establish that some items that incorporate other sensitive materials may not be acquired from specified sources.
Acquiring Specialty Metals
Domestic sourcing restrictions for DOD acquisition of specialty metals first appeared in the FY1973 DOD appropriations bill (P.L. 92-570) as an expansion of domestic content restrictions on departmental purchases of food, clothing, and other goods. These restrictions are commonly known as the Berry Amendment. The Berry Amendment sourcing restrictions were included in annual DOD appropriations legislation from 1941 until 2002, when they were permanently codified by the FY2002 National Defense Authorization Act (NDAA, P.L. 107-107). In 2006, the FY2007 NDAA (P.L. 109-364) separated the
specialty metal-related provisions into a new section of the U.S. Code (10 U.S.C. §4863).
Applicability of Restrictions The specialty metals domestic sourcing restrictions apply to all DOD prime contracts and subcontracts. For the purposes of the restriction, 10 U.S.C. §4863 defines a specialty metal as any of the following metals or metal alloys:
• Steel with a maximum alloy content exceeding one or more of
the following limits: manganese, 1.65%; silicon, 0.60%; copper, 0.60%; or containing more than 0.25% of any of the following elements: aluminum, chromium, cobalt, niobium (columbium), molybdenum, nickel, titanium, tungsten, or vanadium.
• Metal alloys consisting of nickel, iron-nickel, and cobalt base
alloys containing a total of other alloying metals (except iron) in excess of 10%.
• Titanium and titanium alloys. • Zirconium and zirconium base alloys.
DOD uses the foundry location where the final melting or similar production of a specialty metal takes place to determine its origin. For example, titanium sponge— unwrought titanium that has not been melted—that has been manufactured in Kazakhstan, shipped to the United States, and melted into ingots at a foundry in Ohio would be considered compliant with the specialty metals domestic sourcing mandate. Under the specialty metals restrictions, DOD generally may not acquire certain military platforms or weapon systems—or components of these platforms and systems—that contain any amount of a specialty metal that was not melted or produced in the United States.
The restriction applies to aircraft; missile and space systems; ships; tank and automotive items; weapon systems; and ammunition. DOD and its prime contractors are also prohibited from directly acquiring any specialty metal (e.g., metal sheets, rods, plates) if it was not melted or produced in the United States.
Exceptions Law and policy provide a number of exceptions to the specialty metals sourcing mandate, including the following selected examples:
• circumstances where the Secretary of Defense or a secretary of
a military department determines that compliant specialty metal of satisfactory quality and sufficient quantity, and in the required form, cannot be procured as and when needed;
• acquisitions outside the United States in support of combat
operations or contingency operations;
• acquisitions for which the use of other-than-competitive
procedures has been approved when the need for materials or end items is of an unusual and compelling urgency;

• acquisitions where the prime contract is at or below the
simplified acquisition threshold (generally $250,000);
• situations where an acquisition furthers an international
agreement (e.g., trade or offset agreements) with a qualifying country;
• purchases of electronic components, such as diodes or
integrated circuits, unless the Secretary of Defense, pursuant to a recommendation of the Strategic Materials Protection Board, determines that the domestic availability of a particular electronic component is critical to national security;
• covered items incorporating specialty metals that were not
melted in the United States if the total amount of noncompliant specialty metals in such an item does not exceed 2% of the total weight of specialty metals in the item;
• commercially available off-the-shelf (COTS) items containing
specialty metals, except in certain circumstances;
• acquisitions of some commercially available items (e.g.,
fasteners, high-performance magnets);
• acquisition of commercial derivative military articles in certain
circumstances; and
• items containing noncompliant materials if the acceptance of
such items is necessary to the national security interests of the United States.
Acquiring Sensitive Materials
DOD sourcing restrictions for the acquisition of sensitive materials first appeared in the FY2019 NDAA (P.L. 115- 232). In contrast to the specialty metals restrictions, 10 U.S.C. §4872 establishes that these materials, or finished products containing these materials, may not generally be sourced from four countries: the Democratic People’s Republic of Korea, the People’s Republic of China, the Russian Federation, or the Islamic Republic of Iran. These sourcing prohibitions apply only to DOD.
In an explanatory statement accompanying the FY2022 NDAA, Congress expressed concern that the aforementioned countries were attempting to circumvent these prohibitions and directed DOD to provide certain congressional committees with a briefing on the matter, to include proposals for countering such attempts.
Applicability of Prohibitions The sourcing prohibitions for sensitive materials apply to all DOD prime contracts and subcontracts at any tier. Covered materials include
• samarium-cobalt magnets; • neodymium-iron-boron magnets; • tungsten metal powder; • tungsten heavy alloy or any finished or semi-finished
component containing tungsten heavy alloy; and
• tantalum metals and alloys.
Under these sourcing prohibitions, DOD generally may not directly acquire sensitive materials that were mined, refined, separated, or melted in the four specified countries, or military platforms or weapon systems containing sensitive materials melted or produced in the four specified countries. The prohibitions apply to aircraft, missile and space systems, ships, tank and automotive items, weapon systems, and ammunition.
DOD is also generally prohibited from selling covered materials from the National Defense Stockpile to the
specified nations or to any third party reasonably believed to be acting as a broker or agent for a covered nation or an entity in a covered nation. The National Defense Stockpile was established by Congress in 1939 (50 U.S.C. §§98 et seq.) to acquire and retain strategic and critical materials to decrease or prevent the potential dependence of the United States on foreign sources for supplies of these materials in times of national emergency.
Exceptions Law and policy provide limited exceptions to these prohibitions, applicable to
• circumstances where the Secretary of Defense determines that
compliant materials of satisfactory quality and quantity, in the required form, cannot be procured as and when needed at a reasonable price;
• procurement or sale of covered materials, or end items
containing such materials, outside of the United States for use outside of the United States;
• acquisitions at or below the simplified acquisition threshold; • purchase of a COTS end item containing covered materials,
barring COTS end items that are composed of 50% or more of covered sensitive materials by weight, or mill products (e.g., metal sheets) that have not been incorporated into an end item or component;
• purchase of electronic devices containing covered materials,
unless the Secretary of Defense, pursuant to a recommendation of the Strategic Materials Protection Board, determines that the domestic availability of a particular electronic device is critical to national security; or
• purchase of an end item containing a neodymium-iron-boron
magnet manufactured from recycled material if the milling of the recycled material and sintering of the final magnet takes place in the United States.
