AD/CVD: the duty risk that arrives years later
Antidumping duties offset foreign goods sold below normal value; countervailing duties offset foreign subsidies. If your product and origin fall under an AD/CVD order, what you pay at entry is only a cash deposit of estimated duties — final liability is set retrospectively, and importers can receive bills (plus interest) years after the goods sold, with duties doubled if the required non-reimbursement statement is missing. There is no 'typical rate' worth quoting: rates are order- and producer-specific. The check is free and official: search your product and origin in CBP's public AD/CVD database before you commit to inventory.
Why this is a sourcing decision, not a customs formality
AD/CVD scope is written around product descriptions, not HS codes alone — orders on categories sellers actually touch (hardware, furniture components, aluminum goods, solar, steel articles and more, frequently China-origin) can capture goods you didn't expect. The asymmetry is the point: a covered product can turn a healthy margin into a retroactive loss on inventory you already sold, because the final rate lands ~years later. If the official search shows your category near any order's scope, that's a professional-review moment with a broker before the purchase order, and often a reason to source the same product from an uncovered origin.
Common questions
- My supplier says their goods aren't covered. Enough?
- No — scope rulings bind, supplier assurances don't, and the importer of record carries the liability. Check the official database yourself and get a broker's read for anything close.
Official sources behind these numbers
- Dumping occurs when a foreign producer/exporter sells a product in the US below 'normal value'; subsidization is government financial assistance benefiting production or export. Antidumping and countervailing duties are intended to offset the value of the dumping and/or subsidization, leveling the playing field for injured domestic industries U.S. Customs and Border Protection · verified 2026-07-22
- To determine whether a product+origin is subject to AD/CVD, review the scope of AD/CVD orders: the public AD/CVD Search of Commerce instructions and case/rate data is at https://trade.cbp.dhs.gov/ace/adcvd/adcvd-public/#, Commerce Federal Register notices are at https://access.trade.gov/public/FRNoticesListLayout.aspx, and interested parties may request a binding scope ruling from Commerce.

- AD/CVD paid at entry are cash deposits of estimated duties; final duty liability is set retrospectively when Commerce completes an administrative review. The final amount may increase, decrease, or stay the same; CBP bills the importer for any increase plus interest (or refunds overpayment plus interest). The process from importation to final assessment takes approximately three years on average U.S. Customs and Border Protection · verified 2026-07-22
