Frequently asked questions

What is AD/CVD case A-428-807?

A-428-807 is a U.S. antidumping duty (AD) order on sodium thiosulfate from Germany, issued by the U.S. Department of Commerce. It is part of the trade-remedy regime that levies cash deposits at entry on imports found to be sold below fair value (AD) or to benefit from foreign government subsidies (CVD).

What is the deposit rate for A-428-807?

A-428-807 has no published country-wide rate in Tandom's catalog at this time. Cash deposits are still owed at entry — the applicable rate depends on the specific manufacturer/exporter and the most recent administrative review. Check the linked Federal Register notice and the manufacturer rates for this case for the operative number.

Is AD/CVD case A-428-807 still active?

A-428-807 is on the U.S. AD/CVD register and is currently in active status — cash deposits apply at entry on every shipment in scope.

How do I check if my shipment falls within the scope of A-428-807?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (1 flagged); and (2) the product's country of origin — this order applies to imports from Germany. The order's scope text — also on this page — is the legally binding description. When borderline cases arise, importers can request a formal scope ruling from Commerce. Tandom's lookup tool matches your HTS + origin against every active order in seconds.

What HTS codes are covered by A-428-807?

A-428-807 flags 1 HTS code in Tandom's catalog. The full list is shown on this page. HTS coverage alone does not guarantee scope — physical-characteristic exclusions in the scope text may carve out specific products.
