- Describe the merchandise from engineering and purchasing records before searching. Avoid relying on the marketplace title alone.
- Verify a current US HTS candidate in the US HTS workflow, but label it as a search input rather than a scope conclusion.
- Search the Commerce AD/CVD system by product, country, case number, and HTS candidate. Review both orders in place and relevant proceedings.
- Open the order or notice and read the complete scope, including physical descriptions, technical thresholds, exclusions, and any scope rulings that match the product facts.
- Search CBP AD/CVD messages for current deposit instructions. Match the producer, exporter, case, and effective date rather than copying the first rate shown.
- Record uncertainty explicitly. When the product sits near a scope boundary, use the responsible Commerce contact, broker, counsel, or formal scope path.
- Create a paid Classification Case when the product will be imported repeatedly so facts, sources, risk review, and exports remain together.
- Recheck before entry when the supplier, producer, product specification, origin, HTS candidate, or effective date changes.
Guide
How to Check AD/CVD by HTS Code and Country of Origin
A source-backed workflow for screening US antidumping and countervailing duty exposure by product, HTS candidate, country, case number, scope language, and entry date.
Answer Summary
Preparation checklist
AD/CVD orders are administered separately from ordinary HTS duty rates. A normal tariff lookup can be complete and still omit an AD/CVD cash-deposit issue.
An HTS number is a useful search key, but scope language, product characteristics, country, producer or exporter, case status, and entry date control the review.
Do not convert an investigation-wide or “all others” rate into a product quote until the applicable order, party, date, and CBP instructions have been checked.
Required fields or decision table
Fields to prepare before the document draft
| Field or decision | What to prepare |
|---|---|
| Physical product identity |
|
| HTS candidate | Record the full US HTS candidate, source edition, and reasoning. Use it to search, not as a substitute for reading scope language. |
| Country facts | Keep country of manufacture and substantial-transformation evidence separate from ship-from country, seller address, and warehouse location. |
| Producer and exporter | Record the legal producer and exporter names exactly. Rates and instructions can be party-specific, and a supplier brand may not identify the producer of record. |
| Case and order identifiers | Capture AD or CVD case number, order title, product country, investigation or review status, and links to the Commerce record. |
| Scope language | Save the scope text and identify the product facts that appear to include, exclude, or leave uncertainty. Do not paraphrase away technical qualifiers. |
| Deposit instruction | Check the current CBP AD/CVD message for the relevant case, producer/exporter, rate, effective date, and instruction type. |
| Entry context | Record anticipated entry date, importer, customs value, quantity, and broker handoff. Final liability can differ from the cash deposit collected at entry. |
Step-by-step preparation
How to prepare the draft
Ecommerce example
How this looks in a seller workflow
A marketplace seller imports metal shelving from a trading company in a third country. The invoice identifies the ship-from country, while manufacturing records identify a different production country. The supplier provides one HTS number but no producer name.
The seller first records dimensions, steel grade, assembly condition, finish, intended use, manufacturer, and origin evidence. Commerce search results are filtered by the manufacturing country and product terms; the HTS number is used only as another search route.
If an order appears relevant, the seller retains the scope text, case number, producer/exporter information, current CBP message, and unresolved questions in one case record before asking the broker to confirm treatment.
- Product facts before keywords.
- Manufacturing country before ship-from country.
- Scope text before rate.
- Producer/exporter match before party-specific deposit.
- Dated evidence before landed-cost approval.
Verification checklist
Review the record before it enters a shipment or filing workflow
- The physical merchandise is described beyond its sales title.
- The HTS candidate has a current source and is not treated as scope proof.
- Manufacturing origin is supported independently.
- Producer and exporter legal names are known.
- The order, scope text, case number, and status are retained.
- The deposit instruction matches party and date.
- Cash deposit and final duty liability are not presented as identical.
- Uncertainty has an escalation owner.
- The result is rechecked after material product or supplier changes.

Common mistakes
What to avoid
- Treating the ordinary HTS rate as the complete duty result.
- Treating an HTS match as proof that an order covers the product.
- Searching the ship-from country instead of manufacturing origin.
- Ignoring producer and exporter identity.
- Copying a rate from an old message or a different review period.
- Calling a cash deposit the final duty liability.
- Using a generic marketplace description that hides scope facts.

FAQ
Common questions
Are AD/CVD duties listed in the HTS?
No. USITC explains that AD/CVD is separate from ordinary HTS tariffs.
Can I search AD/CVD by HTS code?
Yes, as one search route. Also search product, country, case, producer, and exporter.
Does an HTS match prove that an order applies?
No. Scope language and the actual merchandise facts must be reviewed.
Which country should I use in the search?
Use the supported country-of-origin or manufacturing facts, not merely the dispatch country.
Why does the producer or exporter matter?
Instructions and rates can identify specific companies or an all-others category.
Is the cash-deposit rate the final duty?
Not necessarily. Final liability can be determined later through the administrative process.
What if the scope language is unclear?
Preserve the uncertainty and use the listed Commerce contact or qualified review path.
When should a saved case be rechecked?
Recheck when product facts, supplier parties, origin, classification, or entry date changes.
