Agriculture in the WTO: Limits on Domestic Support

Summary
Omnibus U.S. farm legislation—referred to as the farm bill—is renewed about every five years.
Farm income and commodity price support programs have been a part of U.S. farm bills since the
1930s. Each successive farm bill usually involves some modification or replacement of existing
farm programs. A key question likely to be asked of every new farm proposal or program is how
it will affect U.S. commitments under the World Trade Organization’s (WTO’s) Agreement on
Agriculture (AoA) and its Agreement on Subsidies and Countervailing Measures (SCM).
The United States currently is committed, under the AoA, to spend no more than $19.1 billion
annually on those domestic farm support programs most likely to distort trade—referred to as
amber box programs and measured by the aggregate measure of support (AMS). The AoA spells
out the rules for countries to determine whether their policies—for any given year—are
potentially trade-distorting, and how to calculate the costs.
An additional consideration for WTO compliance—the SCM rules governing adverse market
effects resulting from a farm program—comes into play when a domestic farm policy effect spills
over into international markets. The SCM details rules for determining when a subsidy is
“prohibited” (e.g., certain export- and import-substitution subsidies) and when it is “actionable”
(e.g., certain domestic support policies that incentivize overproduction and result in significant
market distortion—whether as lower market prices or altered trade patterns). Because the United
States is a major producer, consumer, exporter, and/or importer of most major agricultural
commodities, the SCM is relevant for most major U.S. agricultural products. As a result, if a
particular U.S. farm program is deemed to result in market distortion that adversely affects other
WTO members—even if it is within agreed-upon AoA spending limits—then that program may
be subject to challenge under the WTO dispute settlement procedures.
Designing farm programs that comply with WTO rules can avoid potential trade disputes. Based
on AoA and SCM rules, U.S. domestic agricultural support can be evaluated against five specific
successive questions to determine how it is classified under the WTO rules, whether total support
is within WTO limits, and whether a specific program fully complies with WTO rules.
1. Can a program’s support outlays be excluded from the AMS total by being placed
in the green box of minimally distorting programs?
2. Can a program’s support outlays be excluded from the AMS total by being placed
in the blue box of production-limiting programs?
3. If amber, will support be less than 5% of production value (either product-
specific or non-product-specific) thus qualifying for the de minimis exclusion?
4. Does the total, remaining annual AMS exceed the $19.1 billion amber box limit?
5. Even if a program is found to be fully compliant with the AoA rules and limits,
does its support result in price or trade distortion in international markets? If so,
then it may be subject to challenge under SCM rules.

Agriculture in the WTO: Limits on Domestic Support

Introduction
Omnibus U.S. farm legislation—referred to as the farm bill—is renewed about every five years.
Farm income and commodity price support programs have been a part of U.S. farm legislation
since the 1930s.1 Each successive farm bill usually involves some modification or replacement of
existing farm programs.
Most agricultural provisions of the current omnibus farm bill, the Food, Conservation, and
Energy Act of 2008 (P.L. 110-246), expired on September 30, 2012, or are expiring with the 2012
crop year.2 Ultimately the current farm bill will either be replaced with new legislation,
temporarily extended, or allowed to lapse and be replaced with “permanent law”—a set of
essentially mothballed provisions for the farm commodity programs that date from the 1930s and
1940s. Whatever emerges as new farm policy in 2014 will include a farm safety net with some
form of farm commodity price and income supports.
WTO Commitments May Influence U.S. Farm
Policy Choices

A potential major constraint affecting U.S. agricultural policy choices is the set of commitments
made as part of membership in the World Trade Organization (WTO), with its various agreements
governing agriculture and trade, including dispute settlement.3 With respect to disciplines
governing domestic agricultural support, two WTO agreements are paramount—the Agreement
on Agriculture (AoA)4 and the Agreement on Subsidies and Countervailing Measures (SCM).5
In general, domestic policies or programs found to be in violation of WTO rules may be subject
to challenge by another WTO member under the WTO dispute settlement process. If a WTO
challenge occurs and is successful, the WTO remedy likely would imply the elimination,
alteration, or amendment by Congress of the program in question to bring it into compliance.
Since most governing provisions over U.S. farm programs are statutory, new legislation could be
required to implement even minor changes to achieve compliance.6 As a result, designing farm
programs that comply with WTO rules can avoid potential trade disputes.
This report provides a brief overview of the WTO commitments most relevant for U.S. domestic
farm policy. A key question that policy makers ask of virtually every new farm proposal is, how
will it affect U.S. commitments under the WTO? The answer depends not only on cost, but also
on the proposal’s design and objectives, as described below.

Agriculture in the WTO: Limits on Domestic Support

Agreement on Agriculture (AoA)
Under the AoA, WTO member countries agreed to general rules regarding disciplines on
domestic subsidies (as well as on export subsidies and market access). The AoA’s goal was to
provide a framework for the leading members of the WTO to make changes in their domestic
farm policies to facilitate more open trade.
The WTO’s AoA categorizes and restricts agricultural domestic support programs according to
their potential to distort commercial markets. Whenever a program payment influences a
producer’s behavior it has the potential to distort markets (i.e., to alter the supply of a
commodity) from the equilibrium that would otherwise exist in the absence of the program’s
influence. Those outlays that have the greatest potential to distort agricultural markets—referred
to as amber box subsidies—are subject to spending limits.7 In contrast, more benign outlays (i.e.,
which cause less market distortion) are exempted from spending limits under green box, blue box,
de minimis, or special and differential treatment exemptions.8
The AoA contains detailed rules and procedures to guide countries in determining how to classify
its programs in terms of which are most likely to distort production and trade; in calculating their
annual cost, measured by the Aggregate Measure of Support (AMS) index; and in reporting the
total cost to the WTO. Specifically, the WTO uses a traffic light analogy to group programs.
Green Box programs are minimally or non-trade distorting and not subject to any
spending limits.
Blue Box programs are described as production-limiting. They have payments
that are based on either a fixed area or yield, or a fixed number of livestock, and
are made on less than 85% of base production. As such, blue box programs are
also not subject to any payment limits.
Amber Box programs are the most market-distorting programs and are subject to
a strict aggregate, annual spending limit. The United States is subject to a
spending limit of $19.1 billion in amber box outlays subject to certain de minimis
exclusions.9
Prohibited (i.e., Red Box) programs include certain types of export and import
subsidies and non-tariff trade barriers that are not explicitly included in a
country’s WTO schedule or identified in the WTO legal texts.10
These AoA classifications are described in more detail below in the section entitled, “Questions
for Evaluating WTO Compliance of Domestic Farm Spending.” The most recent U.S. notification
to the WTO of its domestic farm program spending is provided in the Appendix.

7 These spending and subsidy commitments are detailed in each Member’s country schedule. For more information, see
CRS Report RL32916, Agriculture in the WTO: Policy Commitments Made Under the Agreement on Agriculture.
8 WTO special and differential treatment exemptions are reserved for “developing” countries and are thus not relevant
for evaluating U.S. domestic farm policy.
9 Non-commodity-specific support that is below 5% of the value of total agricultural production is deemed sufficiently
benign that it does not have to be included in the amber box. Similarly, commodity-specific support that is below 5% of
that specific commodity’s value of production is deemed sufficiently benign that it does not have to be included in the
amber box.
10 The term “Red Box” is not actually used by the WTO, but is included here to complete the traffic light anology.

Agriculture in the WTO: Limits on Domestic Support

Agreement on Subsidies and Countervailing Measures (SCM)
To the extent that domestic farm policy effects spill over into international markets, U.S. farm
programs are also subject to certain rules under the Agreement on Subsidies and Countervailing
Measures (SCM).11 The SCM details rules for determining when a subsidy is “prohibited” (as in
the case of certain export and import-substitution subsidies) and when it is “actionable” (as in the
case of certain domestic support policies that incentivize overproduction and result in significant
market distortion—whether as lower market prices or altered trade patterns).12
The key aspect of SCM commitments is the degree to which a domestic support program
engenders market distortion. Based on precedent from past WTO decisions, several criteria are
important in establishing whether a subsidy could result in significant market distortions:
• the subsidy constitutes a substantial share of farmer returns or covers a
substantial share of production costs;
• the subsidized commodity is important to world markets because it forms a large
share of either world production or world trade; and
• a causal relationship exists between the subsidy and adverse effects in the
relevant market.
The SCM evaluates the “market distortion” of a program or policy in terms of its measurable
market effects on the international trade and/or market price for the affected commodity:
• did the subsidy displace or impede the import of a like product into the
subsidizing member’s domestic market;
• did the subsidy displace or impede the exports of a like product by another WTO
member country other than the subsidizing member;
• did the subsidy (via overproduction and resultant export of the surplus) result in
significant price suppression, price undercutting, or lost sales in the relevant
commodity’s international market; and
• did the subsidy result in an increase in the world market share of the subsidizing
member?
For any farm program that is challenged under the SCM, a WTO dispute settlement panel will
review the relevant trade and market data and make a determination of whether the particular
program being challenged resulted in a significant market distortion.
Under WTO rules, challenged subsidies that are found to be prohibited by a WTO dispute
settlement panel must be stopped or withdrawn “without delay” in accordance with a timetable
laid out by the panel; otherwise the member nation bringing the challenge may take appropriate
countermeasures. Similarly, actionable subsidies, if successfully challenged, must be withdrawn
or altered so as to minimize or eliminate the distorting aspect of the subsidy, again as laid out by a
WTO panel or as negotiated between the two disputing parties.

Agriculture in the WTO: Limits on Domestic Support

WTO Dispute Settlement Understanding (DSU)
The WTO Understanding on Rules and Procedures Governing the Settlement of Disputes (DSU)
provides a means for WTO members to resolve disputes arising under WTO agreements. WTO
members must first attempt to settle their dispute through consultations, but if these fail, the
member initiating the dispute may request that a panel examine and report on its complaint. The
DSU provides for Appellate Body review of panel reports, panels to determine if a defending
member has complied with an adverse WTO decision by the established deadline in a case, and
possible retaliation if the defending member has failed to do so.
As of December 23, 2013, 474 complaints have been filed under the DSU, with nearly one-half
involving the United States as a complainant or defendant. The Office of the United States Trade
Representative (USTR) represents the United States in WTO disputes.13
Questions for Evaluating WTO Compliance of
Domestic Farm Spending

The United States currently is committed, under the AoA, to spend no more than $19.1 billion per
year on amber box trade-distorting support. The WTO’s AoA procedures for classifying and
counting trade-distorting support are somewhat complex; however, four questions might be asked
to determine whether a particular farm measure will cause total U.S. domestic support to be
above or below the $19.1 billion annual AMS limit. A subsequent fifth question may be asked to
ascertain whether AoA-compliant outlays are also SCM-compliant.
1. Can the measure be classified as a “green box” policy—one presumed to have
the least potential for distorting production and trade and therefore not counted as
part of the AMS?
2. Can it be classified as a “blue box” policy—that is, a production-limiting
program that receives a special exemption and therefore is also not counted as
part of the AMS?
3. If it is a potentially trade-distorting “amber box” policy, can support still be
excluded from the AMS calculation under the so-called 5% de minimis exemption
(explained later in more detail) because total support is no more than 5% of
either:
a. the value of total annual production if the support is non-product specific, or
b. the value of annual production of a particular commodity if the support is
specific to that commodity?
4. If such support exceeds the de minimis 5% threshold (and thus cannot be
exempted), when it is added to all other forms of non-exempt amber box support
is total U.S. AMS still beneath the $19.1 billion limit?
5. If a program is fully compliant with the AoA rules and limits, does its support
result in price or trade distortion in international markets that, in turn, cause

Agriculture in the WTO: Limits on Domestic Support

adverse effects upon another WTO member? If so, then it may be subject to
challenge under SCM rules.
Question 1: Can This Measure Be Placed in the Green Box?
No limits are placed on green box spending, since it is considered to be minimally or non-trade
distorting. To qualify for exemption in the green box, a program must meet two general criteria,
as well as a set of policy-specific criteria relative to the different types of agriculture-related
programs.14 The two general criteria are:
1. It must be a publicly funded government program (defined to include either
outlays or forgone revenue) that does not involve transfers from consumers.
2. It must not have the effect of providing price support to producers.
In addition, every green-box-qualifying program must comply with at least one of the following
criteria and conditions specific to the program itself.
• A “general service” benefitting the agricultural or rural community in general
cannot involve direct payments to producers or processors. Such programs can
include research; pest and disease control; training, extension, or advisory
services; inspection services, including for health, safety, grading, or
standardization; marketing and promotion services, including information advice
and promotion (but not spending for unspecified purposes that sellers could use
to provide price discounts or other economic benefits to purchasers); and
generally available infrastructure like utility, transportation, or port facilities,
water supply facilities, or other capital works construction.
• Public acquisition (at current market prices) and stockholding of products for
food security must be integral to a nationally legislated food security program
and be financially transparent.
Domestic food aid is to be based upon clearly defined eligibility and nutritional
criteria, be financially transparent, and involve government food purchases at
current market prices.
“Decoupled” income support is to use clearly defined eligibility criteria in a
specified, fixed base period; not be related in any way after the base period to (a)
domestic or world prices, (b) type or volume of crop or livestock production, or
(c) factors of production; and, further, not be contingent on any production in
exchange for payments.
• Government financial participation in an income insurance or income safety
net program should define eligibility as agricultural income loss exceeding 30%
of average gross income (or equivalent in net income terms) in the preceding
three-year period (or preceding five-year period, excluding the highest and
lowest years—the so-called Olympic average), with such payment compensating
for less than 70% of the income loss in year of eligibility, and payments based
solely on income, not production, price, or inputs. Total annual payments under

14 The so-called green box is actually Annex 2 of the AoA, WTO Legal Texts.
Congressional Research Service
5

Agriculture in the WTO: Limits on Domestic Support

this and natural disaster relief (see next paragraph) cannot exceed 100% of a
producer’s total loss.
• Payments (whether direct or through government crop insurance) for natural
disaster relief are to use eligibility based on formal government recognition of
the disaster. Payments are to be determined by a production loss exceeding 30%
of production in the preceding three-year (or five-year Olympic average) period,
apply only to losses of income, livestock, land, or other production factors, and
cannot exceed the total replacement cost or require types/quantities of future
production. Total annual payments under this and the income insurance or safety
net measure cannot exceed 100% of a producer’s total loss.
Structural adjustment through producer retirement shall tie eligibility to
clearly defined criteria in programs to facilitate producers’ “total and permanent”
retirement from agricultural production or their movement into nonagricultural
activities.
Structural adjustment through resource retirement shall be determined
through clearly defined programs designed to remove land, livestock, or other
resources from marketable production, with payments (a) conditioned on land
being retired for at least three years and on livestock being permanently disposed;
(b) not contingent upon any alternative specified use of such resources involving
marketing agricultural production; and (c) not related to production type/quantity,
or to prices of products using remaining productive resources.
Structural adjustment provided through investment aids must be determined
by clearly defined criteria for programs assisting financial or physical
restructuring of a producer’s operations in response to objectively demonstrated
structural disadvantages (and may also be based on a clearly defined program for
“re-privatization” of agricultural land). The amount of payments (a) cannot be
tied to type/volume of production, or to prices, in any year after the base period;
(b) shall be provided only for a time period needed for realization of the
investment in respect of which they are provided; (c) cannot be contingent on the
required production of designated products (except to require participants not to
produce a designated product); and (d) must be limited to the amount required to
compensate for the structural disadvantage.
Environmental program payments must have eligibility determined as part of a
clearly defined government environmental or conservation program, and must be
dependent upon meeting specific program conditions, including conditions
related to production methods or inputs. Payments must be limited to the extra
costs (or loss of income) involved with program compliance.
Regional assistance program payments shall be limited only to producers in a
clearly designated, contiguous geographic region with definable economic and
administrative identity, considered to be disadvantaged based on objective,
clearly defined criteria in the law or regulation, which indicate that the region’s
difficulties are more than temporary. Such payments in any year (a) shall not be
related to or based on type/volume of production in any year after the base period
(other than to reduce production) or to prices after the base period; (b) where
related to production factors, must be made at a degressive rate above a threshold
level of the factor concerned; and (c) must be limited to the extra costs or income
loss involved in agriculture in the prescribed area.

Agriculture in the WTO: Limits on Domestic Support

In summary, the above measures are eligible for placement in the green box (i.e., exempted from
AMS) as long as they (1) meet general criteria one and two, above; and (2) additionally comply
with any criteria specific to the type of measure itself. If these conditions are satisfied, no further
steps are necessary; the measure is exempt.15 However, if not, then the next step is to determine
whether it qualifies for the blue box exemption.

Question 2: Can This Measure Be Placed in the Blue Box?
No limits are placed on blue box spending, in part because it contains safeguards to prevent
program incentives from expanding production. To qualify for exemption in the blue box,16 a
program must be a direct payment under a production-limiting program,17 and must also either:
• be based on fixed areas and yields, or
• be made on 85% or less of the base level of production, or,
• if livestock payments, be made on a fixed number of head.
If these conditions are satisfied, the measure is exempt. However, if not, then it is considered to be
an amber box policy, and the next step is to determine whether spending is above or below the
5% de minimis rate (see below).

Question 3: If Amber, Will Support Exceed 5% of Production Value?
The AoA states that developed country members (including the United States) do not have to
count, when calculating their total AMS, the value of amber box programs whose total cost is
small (or benign) relative to the value of either a specific commodity, if the program is
commodity-specific, or the value of total production, if the program is not commodity-specific.18
In other words, “amber box” (i.e., potentially trade-distorting) policies may be excluded under the
following two de minimis exclusions.
Product-specific domestic support, whereby it does not exceed 5% of the
member’s “total value of production of a basic agricultural product during the
relevant year.” Support provided through all of the measures specific to a
product—not just a single measure in question—is tallied to determine whether
the 5% level is exceeded. For example, 5% of the value of the 2011 U.S. corn
crop was $3.8 billion compared with corn-specific AMS outlays of $13.4 million.
As a result, the entire $15.1 million was exempted from inclusion under the AMS
limit for the marketing year 2011. In contrast, U.S. sugar support of $1.416

15 For examples of U.S. outlays on various green box programs, see the Appendix of this report which contains the
most recent U.S. notification to the WTO of its domestic farm program spending.
16 Article 6.5, AoA, WTO Legal Texts.
17 An example of a production-limiting program is the now-abandoned U.S. target-price, deficiency-payment program
that linked payments to land set-aside requirements. The target-price, deficiency-payment program was first established
under the 1973 farm bill (the Agricultural and Consumer Protection Act of 1973; P.L. 93-86), and was terminated by
the 1996 farm bill (The Federal Agriculture Improvement and Reform Act of 1996; P.L. 104-127). As a result, the
United States only notified blue box payments under this program for the year 1995.
18 Article 6.4, AoA, WTO Legal Texts.
Congressional Research Service

Agriculture in the WTO: Limits on Domestic Support

billion for 2011 easily exceeded its 5% product-specific de minimis of $165.9
million and, therefore, was counted against the AMS limit.
Non-product-specific domestic support, whereby it does not exceed 5% of the
“value of the Member’s total agricultural production.” All non-product-specific
support—not just a single measure—is tallied to determine whether the 5% level
is exceeded. For example, the value of 2011 U.S. agricultural production was
notified to the WTO as $380.8 billion. As a result, the 5% threshold for non-
product-specific support was calculated as $19 billion. The United States notified
outlays of $9.2 billion for non-product-specific support in 2011. As a result, the
entire $9.2 billion was exempted from inclusion under the AMS limit.
These provisions are known as the so-called de minimis clause. To reiterate, it is not enough to
determine whether a single amber box measure (i.e., one not classified as either green or blue) by
itself may be beneath the 5%-of-production-value trigger. Its level of support must be added to
the support provided by other non-exempt (amber box) measures. If the cost of any particular
measure effectively boosts the total support above 5%, then all such support must be counted
toward the U.S. total annual AMS.

Question 4: Does Total Annual AMS Now Exceed $19.1 Billion?
Finally, all support that fails to qualify for an exemption is added for the year.
• If total U.S. AMS does not exceed $19.1 billion, the WTO commitment is met.
• If it does exceed $19.1 billion, the WTO commitment is not met.
Through 2011, the most recent year for which the United States has made notifications to the
WTO, the United States has never exceeded its AMS limit. The closest approach was in 2000,
when the United States notified a total AMS of $16.8 billion.
Question 5: Does Domestic Support Result in Significant Market
Distortion in International Markets?

An additional consideration for WTO compliance—the SCM rules governing adverse market
effects resulting from a domestic farm support program—comes into play when a domestic farm
policy effect spills over into international markets. This is particularly relevant for the United
States because it is a major producer, consumer, exporter, and/or importer of most major
agricultural commodities, but especially of temperate field crops (which are the main
beneficiaries of U.S. farm program support). If a particular U.S. farm program is deemed to result
in market distortion that adversely affects other WTO members—even if it is compliant with all
AoA commitments and agreed-upon spending limits—then that program may be subject to
challenge under the WTO dispute settlement procedures (Brazil’s WTO case against U.S. cotton
programs is a prime example of this).19

Agriculture in the WTO: Limits on Domestic Support

Conclusion
The AoA’s structure of varying spending limits across the amber, blue, and green boxes is
intentional. By leaving no constraint on spending in the green box while imposing limits on AMS
spending, the WTO implicitly encourages countries to design their domestic farm support
programs to be green-box-compliant.20 Negotiations to further reform agricultural trade within the
context of the WTO—referred to as the Doha Round of multilateral trade negotiations—began in
2001.21 They are not expected to be completed in the near future. As lawmakers consider policy
options, other countries will be evaluating not only whether, in their view, these options will
comply with the U.S. commitments under the AoA, but also how they reflect on the U.S.
negotiating position in the Doha Round of talks.
The U.S. objective is for negotiations to result in substantial reductions in trade-distorting support
and stronger rules that ensure that all production-related support is subject to discipline, while
preserving criteria-based “green box” policies that can support agriculture in ways that minimize
