Antidumping and countervailing duty orders add large extra duties on specific products from specific countries, on top of normal tariffs, and they can apply to goods already in a product line. This guide explains how AD and CVD orders work and how importers check their exposure.
Antidumping duties answer pricing: the foreign producer sold into the US below the price it charges at home or below its cost, injuring US producers. Countervailing duties answer government support: subsidies that gave the foreign producer an unfair edge. Many products carry both orders at once, each with its own rate, calculated per foreign producer where the data allows.
Rates are set per exporter, not per product in the abstract. One supplier may carry a low rate because it cooperated and proved fair pricing, while another faces a punitive country wide rate. That makes supplier choice a duty decision: switching factories or countries can move an importer between rates, or into an order's scope entirely.
An order covers goods described in its written scope, which does not always match the tariff codes importers expect. A product can sit outside the listed codes and still be in scope by description, or inside a code and excluded. Importers who check only the tariff schedule miss orders; the scope text, plus scope rulings for edge cases, is the document that decides.
New orders also arrive on products a company already imports. A petition filed this year can produce cash deposit duties next year on a long standing product line, and the importer learns about it from their broker or from an assessment, whichever finds them first. Monitoring petitions in your product space is part of duty watching, not legal trivia.
At entry, importers deposit estimated AD and CVD duties at the rate in force. The final liability is settled later, often much later, through administrative reviews that recalculate rates for the review period. The deposit is an estimate, and the difference arrives as a bill or a refund with interest, which makes these duties a contingent liability finance teams should not treat as settled at the border.
That long tail changes buying maths. A supplier price that looks cheap with a low deposit rate can become expensive after review. Contracts in exposed categories increasingly address who carries review risk, and importers track their entries by order and period so a rate change announcement can be translated into an exposure number quickly.
List your products against current orders by scope description and country, confirm each supplier's individual rate status, and check whether any petitions are pending in adjacent product areas. Your broker can pull order coverage, but the product knowledge about what your goods are and where they are made has to come from you.
Where exposure is real, model it before the next purchase order: deposit cost in landed cost, a reserve for review movement, and an alternative sourcing option with its own duty picture. AD and CVD surprises are rarely small, and the importers hurt worst are the ones who discovered the system existed from their first assessment notice.

Antidumping duties respond to foreign producers selling below fair value. Countervailing duties respond to foreign government subsidies. Both are added on top of normal tariffs under specific orders covering defined products and countries, often at the same time.
Investigations calculate rates per exporter based on their pricing and subsidy data. Cooperative producers with fair pricing can receive low rates, while non cooperative or unexamined producers may face high country wide rates, making supplier choice a duty cost decision.
No. Entry payments are cash deposits at an estimated rate. Administrative reviews later recalculate the actual rate for the period, and importers receive bills or refunds for the difference, sometimes years after the goods arrived.
By reading the order's written scope against the product's description and origin, not just its tariff code, and by checking for scope rulings and pending petitions in the product area. Brokers can confirm coverage, but product facts come from the importer.
