Anti-Dumping and Countervailing Duties (AD/CVD): A US Importer’s Guide
What Are Anti-Dumping and Countervailing Duties?
Anti-dumping (AD) duties and countervailing (CVD) duties are remedial tariffs imposed by the United States to offset unfair foreign trade practices. They are administered jointly by the International Trade Administration (ITA) within the Department of Commerce and the United States International Trade Commission (USITC).
AD duties remedy dumping (the sale of imported goods at less than normal value, typically below the home market price or the cost of production). CVD duties remedy subsidization (foreign government financial assistance that confers a benefit on producers of the imported goods).
The legal authority is the Tariff Act of 1930 as amended (19 U.S.C. 1671 for CVD and 1673 for AD). Active orders are listed at access.trade.gov (the Commerce ACCESS system) and at usitc.gov/trade_remedy.
How AD/CVD Differs from Other Tariffs
AD/CVD duties differ structurally from Section 232, Section 301, and IEEPA tariffs in several important ways.
Product specificity: AD/CVD orders cover narrowly defined products described in a written scope. Section 232 and 301 cover broad HTS-based product categories.
Country and producer specificity: AD/CVD orders apply to specific countries and frequently set different rates for individual exporters within the same country. Section 232 applies globally; Section 301 applies to all China.
Cash deposit and final liability structure: AD/CVD duties are collected as cash deposits at entry, with final liability determined at administrative review (typically 12-18 months after entry). The final rate can be higher or lower than the cash deposit rate, creating refund opportunities or back-duty liability.
Retroactive scope: Critical circumstances determinations can apply duties to entries up to 90 days before preliminary determination, creating retroactive duty liability.
Stacking: AD/CVD stacks with Section 232, Section 301, IEEPA reciprocal, and the standard MFN duty.
The AD/CVD Investigation Process
AD/CVD investigations begin with a petition filed by a US industry against allegedly dumped or subsidized imports. The process follows statutory deadlines.
Day 0: Petition filed. The domestic industry files identical petitions with Commerce ITA and USITC. Commerce ITA evaluates the petition for sufficiency. USITC begins preliminary injury investigation.
Day 20: Commerce ITA initiation. Commerce determines whether to initiate the investigation.
Day 45: USITC preliminary injury determination. USITC determines whether there is reasonable indication of material injury to the domestic industry. A negative determination ends the case.
Day 140 (CVD) or 160 (AD): Commerce preliminary determination. Commerce calculates preliminary subsidy or dumping margins. If affirmative, importers must begin posting cash deposits at the preliminary rates and CBP suspends liquidation.
Day 215 (CVD) or 235 (AD): Commerce final determination. Final dumping or subsidy margins are calculated. Cash deposit rates are adjusted to final rates.
Day 280 (CVD) or 280 (AD): USITC final injury determination. If affirmative, the AD or CVD order is published. If negative, the case ends and cash deposits are refunded.
Day 287: Order published. The order takes effect from the date of the preliminary affirmative determination, with cash deposits required for all entries from that date forward.
Reading the Scope of an Order
The scope of an AD/CVD order is the precise legal description of products covered. The scope is published in the Federal Register notice imposing the order and is binding on importers.
Critical scope elements:
1. Physical description of the merchandise (dimensions, materials, characteristics)
2. HTS subheadings (informational only; the written scope controls)
3. Excluded products explicitly carved out
4. End-use limitations or product form requirements
5. Country of origin coverage
Why HTS classification alone is not sufficient: Many AD/CVD orders cover products that fall under multiple HTS codes, or only certain product configurations within an HTS code. Conversely, not all products under a covered HTS code are necessarily within scope. Scope rulings issued by Commerce ITA clarify ambiguous cases.
Cash Deposits and Final Liability
AD/CVD duties operate on a deposit-and-review system that creates ongoing liability long after entry.
At entry: Importer posts cash deposit at the applicable rate published by Commerce. Rates can be company-specific (for cooperating foreign producers) or country-wide (for non-cooperating producers and the “all others” rate).
At administrative review: Commerce conducts annual administrative reviews on request. The review calculates the final dumping or subsidy margin for the review period (typically the 12 months ending 30 days before the anniversary month). Final rates can differ substantially from cash deposit rates.
At liquidation: CBP liquidates entries at the final rates determined by Commerce. Importers receive refunds (with interest) if final rates are lower than cash deposits, or owe additional duties (with interest) if final rates are higher. Liquidation can occur 18-30 months after entry.
Common High-Risk Categories
Some product categories are particularly heavily covered by AD/CVD orders. Importers in these categories should perform scope analysis on every shipment.
Steel products: Hot-rolled, cold-rolled, corrosion-resistant, plate, OCTG (oil country tubular goods), pipe and tube products from China, Vietnam, South Korea, India, Brazil, Russia, Turkey, and others.
Aluminum products: Aluminum extrusions, common alloy aluminum sheet, foil, and certain wheels from China and other countries.
Solar products: Crystalline silicon photovoltaic cells and modules from China, Taiwan, Cambodia, Malaysia, Thailand, Vietnam.
Wood products: Hardwood plywood, multilayered wood flooring, wooden cabinets and vanities from China and Vietnam.
Tires: Passenger vehicle and light truck tires from various Asian and South American countries.
Chemicals: Numerous specific chemicals, fertilizers, and petrochemical derivatives.
Fasteners and hardware: Steel nails, threaded rod, certain steel fasteners from China and other origins.
Importer Defense Strategies
Scope ruling requests: If an importer believes a specific product is outside the scope of an order, a scope ruling can be requested from Commerce ITA. Scope rulings are precedential and binding on CBP. The process takes 4-12 months.
Substantial transformation analysis: If goods of a covered country are processed in a third country, the importer can argue substantial transformation occurred and the goods are properly attributed to the third country. CBP and Commerce apply rigorous substantial transformation tests, particularly for covered steel and aluminum products.
Administrative review participation: Importers can request review of specific exporters or self-certify. Active participation in reviews can establish individual exporter rates that are lower than the country-wide rate.
Annual rate forecasting: Sophisticated importers model expected final review rates and adjust pricing or sourcing decisions throughout the year, rather than treating cash deposits as final cost.
EAPA: Anti-Circumvention Enforcement
The Enforce and Protect Act (EAPA) of 2015 created a CBP procedure to investigate evasion of AD/CVD orders through trans-shipment, misclassification, or false country-of-origin declarations.
EAPA investigations can result in:
1. Imposition of AD/CVD cash deposits on entries previously declared as non-covered
2. Reliquidation of past entries with back-duty assessment plus interest
3. Civil penalties under 19 U.S.C. 1592 for negligence, gross negligence, or fraud
4. Criminal referral for willful violations
EAPA cases have grown rapidly since 2018, with hundreds of cases per year focused on solar products, hardwood plywood, aluminum extrusions, and steel products. Suspicious indicators include sudden trans-shipment patterns, unusually low declared values, and producer name changes.
Frequently Asked Questions
Are AD/CVD duties refundable?
Cash deposits become final at liquidation. If the administrative review final rate is lower than the cash deposit, the difference is refunded with interest. If higher, additional duty plus interest is owed. Drawback is generally not available for AD/CVD duties on most products.
How do I know if my product is covered?
Check the active orders list on Commerce ACCESS. Read the scope language in the original Federal Register order, not just the HTS list. When in doubt, request a scope ruling.
Do AD/CVD duties stack with Section 232 and Section 301?
Yes. All four (or more) tariff programs can apply to the same shipment. Total duty exposure on covered Chinese steel and aluminum products frequently exceeds 200% ad valorem.
What is the difference between AD and CVD?
AD remedies dumping (selling below normal value). CVD remedies subsidies (foreign government assistance). Many cases involve both AD and CVD investigations on the same product.
How long do AD/CVD orders remain in effect?
Orders are reviewed every 5 years in a sunset review. If revocation would lead to recurrence of dumping or subsidization and material injury, the order is continued for another 5 years. Many orders have been in effect for decades.
