Antidumping and Countervailing Duty Exposure in Sourcing Plans

What is antidumping and countervailing duty exposure?

According to CBP's page on the Enforce and Protect Act, antidumping and countervailing duties are intended to offset dumping and subsidization for injured domestic industries. In the Commerce Department's FAQ on new investigations, an antidumping (AD) case asks whether goods are dumped and a countervailing duty (CVD) case whether they are subsidized, and a CVD case also questions the exporting government. In this guide, exposure is the deposits, assessment differences and interest those duties add.

How does an investigation timeline reach landed cost?

In the same Commerce FAQ, the International Trade Commission (ITC) makes its preliminary injury decision within 45 days of the petition, and a negative decision ends the investigation; Commerce's preliminary determination is due 140 days after initiation for AD and 65 days for CVD, unless extended. According to the FAQ's answer on duty collection, cash deposits normally start once both agencies' preliminary findings are affirmative, from the date Commerce publishes its determination.

According to the FAQ's answer on critical circumstances, duties can reach entries made up to 90 days before the preliminary determination if both agencies find critical circumstances, which petitioners may allege until three weeks before the final determinations. In this guide's view, buying ahead of a preliminary determination is a cost to model, not a safe hedge.

On the ITA's statutory timeline page, Commerce's final AD determination comes 215 days after initiation, the ITC's final 45 days after an affirmative Commerce final, and the order 7 days later, unless extended. Under the same page, an order needs affirmative final determinations from both agencies.

Under a 2011 Commerce rule on provisional measures, the security posted after an affirmative preliminary determination is normally a cash deposit, for a provisional period of at most six months. In the same rule's reading of the statute, the difference is refunded if the final margin is lower and disregarded if it is higher.

In this guide's view, turn those dates into a cash plan for each supplier route, with deposits at the preliminary rate and then at each later final rate, and re-run it whenever a deadline moves.

According to the abstract of a 2024 peer-reviewed study by Wang and Ng, which used US customs data and a difference-in-differences design for US imports from China, antidumping measures had substantial trade-dampening effects at the product level and raised import prices by more than the cost increases the duties caused. In this guide's view, plan for price effects beyond the deposit when goods fall within an order, without assuming that finding holds elsewhere.

Why is the cash deposit not the final duty?

Under 19 CFR 351.212, Commerce's assessment rule, the United States assesses retrospectively: final AD and CVD liability is set after import, generally in a review of a discrete period. Where no review is requested, entries are assessed at the latest completed review's rate or, failing that, the deposit rate at entry, according to the same rule.

In Commerce's administrative review rule, 19 CFR 351.213, an importer may request a review of an exporter or producer whose goods it imported, in the order's anniversary month, and an AD review normally covers the preceding 12 months. Under the rule's time limits, Commerce's preliminary results are due within 245 days after that month and final results within 120 days after them, extendable to 365 and 180 days.

In Commerce's final results notice of June 12, 2026 for cold-drawn mechanical tubing from India (A-533-873), the review covered entries from June 1, 2023, to May 31, 2024, and its deadlines had moved through shutdown tolling of 47 and 21 days and a 52-day postponement. According to the same notice, Commerce's assessment instructions go to CBP no earlier than 35 days after publication. In this guide's reading, June 2023 entries from the reviewed exporters waited roughly three years for final assessment.

Under the assessment rule's deposit cap, for entries before the ITC's final injury notice, any excess of the final duty over the provisional duty is disregarded, and a lower final duty is assessed instead. Under its interest provision, interest on over- or underpayments for entries after the order's publication runs from the deposit date to liquidation.

In this guide's view, carry two figures for each open entry, the deposit paid and a planning range for the final duty, until it liquidates, and do not budget a lower rate from the latest review for entries in periods that review did not cover.

Which supplier and origin facts decide the rate?

Under Commerce's cash deposit instructions in the tubing notice, a reviewed company gets its new margin, an exporter covered in an earlier segment keeps its latest company-specific rate, an unreviewed exporter whose producer was reviewed takes the producer's rate, and all others deposit at the all-others rate, 5.87 percent ad valorem in that June 12, 2026 notice for A-533-873. In this guide's view, the producer and exporter pair, not just the country, sets the deposit rate.

In a 2021 client alert by the law firm Arent Fox, which predates later rule changes, goods completed or assembled in a third country may still owe US AD/CVD duties even if their origin differs from the order's country, and Commerce and CBP origin tests occasionally reach different conclusions. According to the same alert, supplier evasion is attributed to the US importer regardless of the importer's knowledge.

Under the Enforce and Protect Act process that CBP describes, an interested party can allege that an importer is evading AD/CVD duties, and CBP may collect information from that party, the importer, the foreign producer or exporter and its government. In the Arent Fox alert's account, CBP typically follows an allegation with a CF-28 asking the importer about origin and supply chain.

In this guide's view, origin evidence is a sourcing record first: ask each affected supplier to name the producer and plant and show where order-country inputs enter its bill of materials. Inquiry responses and scope questions belong with a licensed customs broker or trade counsel.

How should contracts treat duty changes and reimbursement?

Under 19 CFR 351.402(f), Commerce's reimbursement rule, Commerce deducts from the export price any AD or CVD duty that the exporter or producer paid for the importer or reimbursed to it, and the importer must certify to CBP before liquidation whether it has been reimbursed or has any agreement for payment or refund. Under the rule's presumption clause, Commerce may presume reimbursement when no certificate is filed. In this guide's reading, a supplier that absorbs the duty lowers the export price Commerce uses and can raise the duty, so it rarely helps the importer.

In the tubing notice's reminder to importers, a missing certificate could lead Commerce to presume reimbursement and assess double antidumping duties. In CBP's protest ruling HQ 229859 of December 31, 2003, double antidumping duties on Chinese-origin castings from a Canadian supplier were upheld because the importer filed no certificates before liquidation.

In this guide's view, settle three commercial questions with trade counsel before signing: who is importer of record and funds deposits, how a new deposit or final rate reaches future prices, and what each party may do when a case starts. Any term under which a supplier pays or refunds these duties can be an agreement of the kind covered by the certification rule, and whether a specific term is one is a question for trade counsel.

What should a trade remedy exposure map contain?

The map below lists fields to review for each affected supplier route after each new notice; it is a planning aid, not a compliance determination.

In the Journal's guide library, related guides cover next steps: test a second source with the readiness checks in the dual sourcing guide before moving volume, and if a case reopens the choice of country, compare locations with a nearshoring total-cost model.
