Antidumping and countervailing duties (AD/CVD) are extra US duties on a specific product from a specific country, set case by case to offset dumping, meaning sales below normal value, or foreign government subsidies. The Department of Commerce sets the rates and the scope of each order, the US International Trade Commission decides whether US industry is injured, and CBP collects cash deposits at entry. Deposits can run far above the regular duty: Chinese exporters of wooden bedroom furniture without their own rate deposit 216.01%. Rules as of 30 October 2026. ## How does an AD/CVD order come about? An AD/CVD order starts with a petition from a US industry to both Commerce and the ITC. Commerce investigates whether the goods are dumped or subsidized and by how much, while the ITC investigates whether the US industry is materially injured or threatened. An order is issued only when both final determinations are affirmative. Duties can start before the order. When Commerce makes its first affirmative determination, usually the preliminary one, it tells CBP to suspend liquidation of entries and collect cash deposits from the date it's published. These provisional measures lapse after 120 days, extendable to 180 days in antidumping cases, and resume when the order issues. If Commerce finds critical circumstances, meaning a surge of imports during the investigation, deposits can reach back up to 90 days before suspension of liquidation began. ## What are AD/CVD case numbers and deposit rates? An AD/CVD case number identifies one order: "A" for antidumping or "C" for countervailing, followed by a country code and a case code, as in A-570-890 for wooden bedroom furniture from China. Each producer or exporter with its own rate has a 10-digit company case number under that 7-digit case, and everyone else pays the all-others rate. For China and other non-market economies, exporters that haven't shown independence from the state are part of a country-wide entity with a single rate. In Commerce's August 2026 review of A-570-890, for example, eleven companies were placed in the China-wide entity at 216.01%, and non-Chinese exporters of Chinese furniture without their own rate take the rate of their Chinese supplier. A product can be under both an AD and a CVD order, and they are separate cases with separate rates. The deposit paid at entry is only an estimate. Commerce sets the final duty later, in an administrative review that any interested party can request in the order's anniversary month, and CBP then liquidates the entry at that rate. The final duty can be higher, lower or the same, and CBP bills any increase. The importer of record carries that risk for years after the sale. ## How do you know if a product is covered? Whether a product is covered by an AD/CVD order depends on the written scope of the order, not on its HTSUS code. Orders list HTSUS codes for convenience, but CBP says the scope description is dispositive: a product under a listed code can be outside the order, and one under an unlisted code can be inside it. To check a product before you ship it: 1. Find the product's HTSUS code with the [HS code lookup](https://border.bot/tools/hs-code-lookup), then search CBP's [AD/CVD Search](https://trade.cbp.dhs.gov/ace/adcvd/adcvd-public/) by country, product, HTSUS number or case number; it holds Commerce's instructions to CBP since 1992. 2. Read the scope in the latest Commerce notice for the case in the Federal Register, and check ITA's case list on trade.gov. 3. Find your supplier's own rate, if it has one, and its 10-digit company case number. Without it, the all-others or country-wide rate applies. 4. If the scope is unclear, ask Commerce for a scope ruling. You must deposit AD/CVD while the ruling is pending, and get the deposits back if Commerce rules the product out. An import specialist at CBP's Centers of Excellence and Expertise can give advice, but only Commerce decides what an order covers. If CBP applies an order you think doesn't cover your goods, you can protest within 180 days after liquidation. ## Which online goods face AD/CVD orders? Some AD/CVD orders cover consumer goods an online seller ships, not only industrial inputs. Commerce notices published in 2026 show orders still active on wooden bedroom furniture and ceramic tile from China, mattresses from Poland, wood mouldings and millwork from China, and paper plates from China, where Commerce preliminarily found circumvention in July 2026. Goods under an AD/CVD order are entered with the order's case number, on a type 03 entry when entered formally, and by mail they can't use the postal informal entry process: they need a formal entry. AD/CVD applies on top of the regular duty and the chapter 99 duties, including Section 232, Section 338 and the forced labor duty, whose notes keep antidumping and countervailing duties in place. Continuing the nightstand from the [Section 301 guide](https://border.bot/docs/guides/countries/united-states/section-301): a $1,000 solid wood nightstand from China owes $375 in Section 301 duties. If it falls within the scope of A-570-890 and the exporter has no separate rate, the entry also needs a cash deposit of 216.01%, $2,160.10, bringing duties and deposits to $2,535.10 before fees. ## How does border.bot handle AD/CVD? border.bot's quotes don't include AD/CVD cash deposits today, and no quote warns that an order may apply. The page below explains what the [landed cost calculator](https://border.bot/tools/landed-cost-calculator/united-states) and the API return for goods that may be under an order, and how to add the deposit yourself. - [How border.bot handles AD/CVD](https://border.bot/docs/guides/countries/united-states/ad-cvd/how-border-bot-applies-it): What border.bot's quotes include for US antidumping and countervailing duties today, what they leave out, and how to add an AD/CVD deposit yourself. ## Common questions ### What is the difference between antidumping and countervailing duties? Antidumping duties offset sales below normal value by a foreign producer. Countervailing duties offset subsidies a foreign government gives that producer. The same product can be under both. ### Do AD/CVD duties apply to small parcels? Yes. An order applies to the goods it covers whatever the shipment's value, and mailed goods under an order need a formal entry. ### Can I get AD/CVD deposits back? If Commerce's administrative review sets a final rate below the deposit, CBP refunds the difference when it liquidates the entry. If a scope ruling puts the product outside the order, Commerce normally tells CBP to refund the deposits. ## Sources - [Antidumping and Countervailing Duties (AD/CVD) Frequently Asked Questions](https://www.cbp.gov/trade/priority-issues/adcvd/antidumping-and-countervailing-duties-adcvd-frequently-asked-questions), U.S. Customs and Border Protection, updated 2026-10-16 - [Antidumping and Countervailing Duties](https://www.cbp.gov/trade/priority-issues/adcvd), U.S. Customs and Border Protection, updated 2026-10-23 - [AD/CVD Search](https://trade.cbp.dhs.gov/ace/adcvd/adcvd-public/), U.S. Customs and Border Protection, checked 2026-10-30 - [AD/CVD Proceedings](https://www.trade.gov/data-visualization/adcvd-proceedings), International Trade Administration, checked 2026-10-30 - [File a Scope Ruling Application](https://www.trade.gov/file-scope-ruling), International Trade Administration, checked 2026-10-30 - [Wooden Bedroom Furniture From the People's Republic of China: Final Results of Antidumping Duty Administrative Review; 2024](https://www.federalregister.gov/d/2026-16446), International Trade Administration, Federal Register, 2026-08-12 - [Ceramic Tile From the People's Republic of China: Continuation of Antidumping Duty and Countervailing Duty Orders](https://www.federalregister.gov/d/2026-04120), International Trade Administration, Federal Register, 2026-03-02 - [Mattresses From Poland: Preliminary Intent To Rescind Antidumping Duty Administrative Review](https://www.federalregister.gov/d/2026-20382), International Trade Administration, Federal Register, 2026-10-05 - [Wood Mouldings and Millwork Products From China: Continuation of Antidumping Duty Order and Countervailing Duty Order](https://www.federalregister.gov/d/2026-13103), International Trade Administration, Federal Register, 2026-06-30 - [Certain Paper Plates From China: Preliminary Affirmative Determination of Circumvention](https://www.federalregister.gov/d/2026-13974), International Trade Administration, Federal Register, 2026-07-10 - [Indefinite Suspension of the De Minimis Exemption for Mail Shipments and New Postal Informal Entry Process](https://www.federalregister.gov/d/2026-12669), Federal Register, 2026-06-24 - [Harmonized Tariff Schedule, 2026 Revision 21, chapter 99, U.S. notes 16, 51 and 52](https://hts.usitc.gov/reststop/file?release=currentRelease&filename=Chapter%2099), U.S. International Trade Commission, effective 2026-10-09
