U.S. sets preliminary AD rate on Chinese tin mill products
Commerce preliminarily found that tin mill products from China are sold, or likely to be sold, in the U.S. at less than fair value and that critical circumstances exist. No Chinese company qualified for a separate rate, so all exporters fall under the China-wide entity: a 136.52% margin and a 130.17% cash deposit rate from September 21, 2026. The period of investigation is October 1, 2025, through March 31, 2026.
What changed
The scope covers flat-rolled steel coated or plated with tin (tinplate) or with chromium or chromium oxides (tin-free steel), in coils or cut sheets; chromium-coated tape for fiber optic and telecom cables is excluded only if it meets all seven listed tests.
Named HTSUS lines are 7210.11.0000, 7210.12.0000, 7210.50.0020, 7210.50.0090, 7212.10.0000, 7212.50.0000, 7225.99.0090 and 7226.99.0180, but the written scope controls. Because of critical circumstances, suspension of liquidation also reaches unliquidated entries made on or after the date 90 days before publication.
The 130.17% deposit is offset for subsidies found in the companion CVD case; if CVD provisional measures expire first, CBP collects the unadjusted 136.52%. Although the title mentions extending provisional measures, the text sets the final determination within 75 days of the September 16, 2026 signature. If it is affirmative, the ITC decides injury; its hearing is set for December 4, 2026.
What an import team should check
- Check the producer and exporter on each invoice: no Chinese company earned a separate rate, and a third-country exporter takes the rate of the Chinese supplier behind it.
- List unliquidated tin mill entries made in the 90 days before September 21, 2026 and ask your customs broker how the retroactive suspension of liquidation applies to them.
- Compare coating, alloy content and HTSUS line with the written scope and the seven-part tape exclusion, and diary the final determination due within 75 days of September 16, 2026.
