Direct answer: To check whether your supplier is subject to AD/CVD, identify your product's HTS code and country of origin, find any active antidumping or countervailing duty order that covers that product-and-country, and then confirm whether your specific exporter has its own rate or pays the order's all-others rate. The data is public; the final call belongs to your customs broker.
The four steps
1. Get the HTS code and country of origin
AD/CVD orders are organized by product and by country. You need both: the Harmonized Tariff Schedule (HTS) classification of your goods and the country where they were produced (origin, not the shipping point). The same product from two different countries can be covered by one, both, or neither.
2. Find any active order that covers it — but read the scope
Use the HTS code to surface candidate orders, then check the order's written scope. This is the step importers most often get wrong. Commerce orders list HTS subheadings for the convenience of U.S. Customs, but the narrative product description is what legally governs — the written scope, not the HTS number, is dispositive (the scope-ruling framework lives in 19 CFR 351.225). So an HTS match is a signal, not a verdict: goods can fall inside a scope even under an unlisted HTS code, and an HTS match can fall outside a narrowly-written scope. Read the scope language, and when in doubt, your broker can request a formal scope ruling from Commerce.
3. Find your exporter's rate
A single order contains multiple rates, and they are exporter- or producer-specific. Match your supplier to one of three categories:
| Your exporter's status | Rate that applies |
|---|---|
| Individually investigated and named | That exporter's own rate |
| Cooperating but not individually examined | All-others or separate rate |
| Not established / non-market-economy entity | Country-wide rate (often the highest) |
The all-others rate is set by statute as a blended figure:
"the estimated all-others rate shall be an amount equal to the weighted average of the estimated weighted average dumping margins established for exporters and producers individually investigated, excluding any zero and de minimis margins, and any margins determined entirely under section 1677e of this title" — 19 U.S.C. 1673d(c)(5)(A)
A named exporter's rate is frequently far below the all-others rate, so identifying your supplier precisely can change the duty by a wide margin.
4. Confirm with your customs broker
A screen narrows the question and shows you the source; it is not a binding determination. The operative cash-deposit rate at the moment of entry — and the final scope call — must be confirmed with your licensed customs broker or, for certainty, a Commerce scope ruling.
Why the exporter matters as much as the product
Two importers bringing in the identical product from the identical country can owe very different duties depending on which exporter shipped the goods. A named exporter might carry a low-single-digit rate while an unnamed supplier falls to a double-digit all-others or country-wide rate. That gap is the single largest lever an importer controls — and it's why a screen that stops at "covered: yes/no" is not enough; it has to resolve the rate down to your exporter.
Do it in seconds
ImportSentry's free Exposure Screener runs exactly these steps against the active AD/CVD universe: enter an HTS code or product and the country of origin (and, optionally, your supplier), and it returns the order, the exporter-specific or all-others rate, the effective date, and the primary Federal Register citation — with the broker-verify fence built in. Then confirm with your broker before you rely on it.
