US AD/CVD case lookup (China-origin)
Catch the AD/CVD order on your supplier before the cash deposit hits the CBP entry.
An AD/CVD order does not show up on the supplier pro forma. It shows up on the CBP entry summary three days before the vessel arrives, as a cash-deposit rate against the manufacturer of record on the bill of lading, per the case-number scope. On a container of HS 7616.99 aluminium extrusions from a Chinese exporter under the A-570-967 plus C-570-968 pair, that combined cash deposit can wipe out the entire imported margin on one entry. The container clears. The wire to Customs and Border Protection does not bounce back.
Search the index of 154 active and recent ITA case numbers by product, HS classification, case number, or order type. Each row returns the case identifier (A-570-XXX, C-570-XXX), the product scope as paraphrased from Commerce, indicative HS subheadings, and the inline URL back to the legacy scope-rulings index plus the ACCESS case-file portal where the binding cash-deposit rate for a specific manufacturer-of-record on a specific entry date can be verified.
Important. Read before using.
The cash-deposit rate at the border is the only number that matters for CBP entry, and it is the only number this dataset deliberately does not assert. Every row duty_rate_text reads "verify per case file on access.trade.gov before invoicing" because the rate varies by manufacturer of record, by entry date, and by the most recent administrative-review or changed-circumstances review. Commerce reviews rates annually; rates change between the date an order was first imposed and the date your container arrives at the wharf.
Use the lookup to find the case file for your supplier and product, then click through to the ACCESS portal to read the current administrative-review final results for the exporter-specific cash-deposit rate. The tool is positioned as a fast indexing layer over the ITA case index, not a substitute for it. Engage US trade counsel before structuring an entry against an unfamiliar case.

Worked example: aluminium extrusions from a Foshan supplier
A Texas distributor is quoting a project that needs 22 metric tonnes of aluminium extrusions from a Foshan supplier. HS classification 7604.21. Supplier quotes USD 3.85 a kilo FOB Yantian, which on the surface beats the domestic fabricator on landed cost. The buyer accepts the quote, the supplier ships, the container arrives at Long Beach, and the broker entry summary flags two cash deposits against the consignment: A-570-967 for anti-dumping and C-570-968 for countervailing, both at the China-wide rate because the supplier never applied for separate-rate status.
The lookup catches this earlier. Search "aluminium extrusions" in the box above and the result panel returns both case files. The duty_rate_text is the hedge "verify per case file on access.trade.gov before invoicing", and the source URLs link to the legacy scope-rulings index where the Foshan exporter can be cross-checked against the cooperative-exporter list. The buyer clicks through, finds the most recent administrative-review final results for the Foshan exporter on the bill of lading, reads the actual cash-deposit rate against that exporter, and now has a real number to slot into the landed-cost calculator alongside the freight, marine insurance, and merchandise processing fee lines. The quote either survives the rebuild or it does not, but the decision happens before the wire instructs, not after the entry posts.
The fix is the supplier-qualification call. Before agreeing terms with any new manufacturer in a sector with an active Commerce order (steel, aluminium, certain chemicals, plywood, solar, tires), pull the case file and confirm the supplier name on the cooperative-exporter list with its specific rate. Suppliers that have responded to the Section A questionnaire and passed verification typically receive a separate rate that is materially below the China-wide entity rate. Suppliers that did not establish separate-rate status land at the punitive figure. The conversation is two minutes; the difference at the border is months of margin.
Frequently asked
What triggers a US AD/CVD order?
A US industry petitions Commerce alleging that imports are sold here below their fair value in the exporter home market (anti-dumping) or are subsidised by a foreign government (countervailing). Commerce investigates, calculates margins, and if the determination is affirmative and the USITC finds material injury, an order is issued. The result is a cash-deposit rate at the border, set per manufacturer of record, per case number. The case number format A-570-XXX covers anti-dumping orders against China; C-570-XXX covers countervailing orders against China; 731-TA-XXXX is the USITC injury investigation number that accompanies the order.
Why does the lookup say cash-deposit rates are not asserted?
The published investigation rate is the rate at the moment of the original determination. Commerce runs annual administrative reviews and changed-circumstances reviews; rates get varied per exporter, per entry date. The number that actually applies to a CBP entry depends on the manufacturer of record on the bill of lading, the date of entry, and the most recent administrative-review final results for that exporter. Only the live ACCESS case-file dossier on access.trade.gov gives the binding cash-deposit rate. This dataset deliberately holds the duty_rate_text as a hedge pointing back to the case file for every row.
How do I get an exporter-specific rate rather than the China-wide rate?
During the original investigation and subsequent administrative reviews, exporters can be selected as mandatory respondents or apply for separate-rate status. Cooperative exporters that respond to the Section A questionnaire and pass Commerce verification typically receive a separate rate calculated specifically for their dumping margin. Non-cooperative exporters and exporters that did not establish separate-rate status receive the China-wide entity rate, which is usually significantly higher (often above 100 percent). The cooperative-exporter list is on the case file.
What is the difference between A-570-XXX and C-570-XXX case numbers?
A-570 is the country prefix for anti-dumping orders against China (570 is the Commerce country code for the People Republic of China). C-570 is the same country prefix for countervailing orders. The two run as separate cases even when they cover the same product (the 967 / 968 pair on aluminium extrusions, the 029 / 030 pair on cold-rolled steel). At the border, CBP collects two cash deposits per entry where both orders are in effect. The dataset keeps the two case numbers as separate rows so the broker entry-note match remains unambiguous.
How do I challenge or reduce a duty on an entry that has already cleared?
Three live mechanisms. First, request an administrative review of the order for the period of review that covers your entry; if the actual dumping margin during that period was lower than the cash deposit, Commerce will issue a refund. Second, file a scope-ruling request if the merchandise is plausibly outside the order scope. Third, on sunset-review years, importers can file substantive responses arguing that revocation is appropriate. Each route is procedure-heavy; engage trade counsel before drafting.
