Antidumping & Countervailing Duties (AD/CVD)
Antidumping (AD) and countervailing duty (CVD) orders are the most frequently used U.S. trade remedies — legal mechanisms to protect American industries from foreign goods sold at unfairly low prices or subsidized by foreign governments. Under 19 U.S.C. §§ 1671–1677n (the Tariff Act of 1930, as amended by the Trade Agreements Act of 1979 and the Uruguay Round Agreements Act), the Department of Commerce investigates whether foreign goods are "dumped" (sold in the U.S. below fair market value) or subsidized by foreign governments, and the U.S. International Trade Commission (ITC) independently determines whether those imports materially injure a U.S. industry. When both agencies make affirmative findings, CBP begins collecting additional duties — often 20–300% on top of normal tariff rates — that can fundamentally reshape import economics. As of 2026, over 400 active AD/CVD orders cover products ranging from solar panels and steel to shrimp and wooden furniture. China is the most common subject, with AD margins routinely in the triple digits, but orders exist against products from over 50 countries. The combined duty burden on some products subject to both an AD order and a CVD order from the same country can be staggering: Chinese solar cells, for instance, face base MFN duties plus Section 301 tariffs (50%) plus CVD rates (variable) plus AD margins (50–250%+), often totaling well over the product's commercial value. Importers who export goods subject to AD/CVD orders can potentially recover duties paid through customs duty drawback.

Legal Authority
- 19 U.S.C. § 1671 — Countervailing duties (CVD): when Commerce determines that a foreign government is providing a countervailable subsidy (financial contribution conferring a benefit) to exporters, and ITC determines that U.S. industry is materially injured or threatened, Commerce issues a CVD order directing CBP to collect duties equal to the subsidy rate
- 19 U.S.C. § 1673 — Antidumping duties (AD): when Commerce determines that foreign merchandise is being sold in the U.S. at less than "normal value" (i.e., dumped), and ITC determines material injury or threat, Commerce issues an AD order directing CBP to collect duties equal to the dumping margin
- 19 U.S.C. § 1677a — Export price / constructed export price: defines how Commerce calculates the U.S. sale price for dumping margin purposes — the "export price" is the FOB price charged to the first unrelated U.S. buyer; adjustments include brokerage, freight, and import duties
- 19 U.S.C. § 1677b — Normal value: defines how Commerce calculates the fair market comparison price — normally the home market price (or third-country price, or constructed value if the home market is not viable); the difference between normal value and the export price is the dumping margin
- 19 U.S.C. § 1675 — Administrative reviews (ARs): after an order is issued, Commerce conducts annual administrative reviews to recalculate dumping margins for the most recent period; updated margins replace the prior rate for each reviewed exporter; importers pay cash deposits at the order rate and receive refunds or pay additional duties after the AR is complete
- 19 U.S.C. § 1675(c) — Sunset reviews: five years after an order is issued, Commerce and the ITC conduct sunset reviews; the order is revoked unless both agencies determine that revocation would likely lead to continuation or recurrence of dumping/subsidies and material injury
How It Works
An AD/CVD case begins when a U.S. industry (producers representing at least 25% of domestic production) files a petition with both Commerce and the ITC; within 20 days both agencies decide whether to initiate. ITC's preliminary determination (45 days) requires only a reasonable indication of injury — a low bar. Commerce is the accounting engine: for antidumping, it compares the exporter's U.S. sale prices against home-market prices for identical or similar products (19 U.S.C. § 1677a, § 1677b), with complex adjustments for physical differences, selling expenses, and credit terms. Foreign producers who don't cooperate with Commerce's questionnaires (which run hundreds of pages) receive adverse facts available (AFA) rates — typically punitive levels set to deter non-cooperation, routinely reaching 100–400% against Chinese respondents. The ITC independently determines whether imports materially injure or threaten the U.S. industry, analyzing import volumes, price effects, and impact on domestic employment, production, and financial performance (19 U.S.C. § 1671); a tied commissioner vote is treated as affirmative.
Once a preliminary determination is made, CBP begins collecting cash deposits — estimated duty payments at the rate Commerce calculated per exporter, with unknown importers paying an "all others" rate (19 U.S.C. § 1675). After each annual administrative review, Commerce publishes final rates; CBP liquidates entries, charging or refunding the difference between the cash deposit rate and the final rate — creating substantial accounting complexity since importers may owe additional duties from entries years earlier, or receive significant refunds. AD/CVD orders are frequently circumvented by transshipping goods through third countries (completing final assembly in Vietnam or Malaysia to avoid a China-specific order); Commerce investigates circumvention allegations and can extend orders to cover transshipped goods, and the ENFORCE and Protect Act (EAPA) gives CBP additional authority to investigate duty evasion at the border.
How It Affects You
If you are a U.S. manufacturer that believes foreign imports are injuring your industry: Filing an AD/CVD petition is your most powerful tool for lasting protection — an order once issued can remain in place indefinitely through successive sunset reviews. The process is real: over 400 orders protect industries from steel to shrimp to solar panels. Hire specialized trade counsel; the petition filing is technical (you need to provide data on the respondents' prices, your industry's financial performance, and estimated dumping margins). Coalition-building is critical — you need to represent a sufficient share of domestic production, and Commerce/ITC respond favorably to petitions with broad industry support. The American Iron and Steel Institute and the Solar Energy Manufacturers for America (SEMA) are examples of industry groups that have organized successful petition efforts. Commerce's and ITC's questionnaire responses (filed publicly at Commerce's EAIS system and ITC's EDIS system) are public records — review prior cases in your industry before filing to understand what to expect.
If you import goods subject to an AD/CVD order and want to manage your exposure: Your cash deposit rate is set per-exporter at the time the order is issued, but administrative reviews reset it annually — the rate you pay today may not reflect the rate you'll ultimately owe at liquidation. High-risk importers ask their customs broker to pull each entry's liquidation status from CBP's ACE system. If your supplier has never participated in an AD administrative review, they're likely paying the "all others" rate (often high); you can request that Commerce include your supplier in the next annual review — if the supplier cooperates and demonstrates low/no dumping, the rate comes down and you get a refund for the review period. On CVD, check whether your supplier can obtain an "exclusion" from the order for specific product specifications Commerce hasn't covered. AD/CVD orders are scope-defined by product description and HTS code — a legitimate product redesign that falls outside the order's scope is a complete defense.
If you are a foreign exporter selling to the U.S. subject to an AD/CVD order: Participate fully in administrative reviews — non-cooperation results in AFA rates that make exporting to the U.S. economically unviable. Build the capacity to respond to Commerce's enormous questionnaires (they cover all home-market sales, cost of production, U.S. sales, and corporate structure). Hire U.S. trade counsel; domestic and foreign parties respond to the same Commerce questionnaire but under entirely different strategic frameworks. Consider whether a price undertaking (suspension agreement) might be available — Commerce sometimes agrees to suspend investigations if the foreign government commits to eliminating the subsidy or raising prices. The U.S.-Mexico tomato suspension agreements are a long-running example.
If you are a consumer or downstream manufacturer that uses imported products covered by an AD/CVD order: Apply for tariff exclusions through Commerce's product exclusion process if available. Alternatively, work with importers or buy from non-covered-country sources. The downstream effects of high AD/CVD duties are real — steel fabricators have complained that steel AD/CVD orders raise their input costs while protecting upstream mills. Commerce's exclusion process (where domestic supply is insufficient to meet demand) is the relief valve; document the case carefully.
State Variations
AD/CVD law is exclusively federal. No state variations.
Implementing Regulations
- 19 CFR Part 351 — Commerce antidumping and countervailing duty regulations (petitions, investigations, reviews, scope, circumvention)
- 19 CFR Part 207 — ITC antidumping and countervailing duty injury investigations (procedures, hearings, determinations)
- 19 CFR Part 159 — CBP liquidation (duty payment and collection upon liquidation of AD/CVD entries)
Pending Legislation
- Multiple exclusion process reform bills — Several members of Congress have proposed making AD/CVD exclusion processes more transparent and binding on Commerce.
- WTO reform discussions — The U.S. has blocked WTO Appellate Body appointments for years over disputes about AD/CVD methodology, leaving WTO appellate review of U.S. AD/CVD determinations effectively paralyzed; legislative reform proposals are pending.
Recent Developments
- In early 2026, Commerce continued AD/CVD orders on carbon and alloy steel wire rod from multiple countries; issued preliminary CVD findings on crystalline silicon photovoltaic cells from India, Indonesia, and Laos; and initiated new investigations on large-diameter graphite electrodes from China and India
- UFLPA enforcement has intersected AD/CVD orders on solar panels — Xinjiang polysilicon enters panels that are then subject to both forced labor restrictions and existing CVD/AD orders, creating layered admissibility challenges for importers
- The ITC self-initiated investigations in March 2026 on the effects of revoking China's Permanent Normal Trade Relations (PNTR) status, which would dramatically escalate AD/CVD and other duties on Chinese imports to Column 2 (Smoot-Hawley) rates
- Commerce's "adverse facts available" methodology for Chinese non-market economy respondents has been upheld by U.S. courts but challenged repeatedly at the WTO, creating ongoing legal uncertainty for importers
- Annual administrative reviews for major orders (steel, aluminum, solar panels, furniture) routinely produce rate changes affecting billions of dollars of imports and generating significant retrospective duty bills and refunds
