Frequently asked questions

What is AD/CVD case C-570-173?

C-570-173 is a U.S. countervailing duty (CVD) order on vanillin from China, 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 C-570-173?

The country-wide cash deposit rate for C-570-173 is 27.33%. This rate applies to importers of non-listed manufacturers/exporters from China. Individual exporters and producers may have lower (or higher) case-specific rates from Commerce administrative reviews — see the manufacturer rates linked from this page where available.

When did C-570-173 take effect, and is it still active?

C-570-173 took effect on July 28, 2025 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 C-570-173?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (2 flagged); and (2) the product's country of origin — this order applies to imports from China. 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 C-570-173?

C-570-173 flags 2 HTS codes 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.

Where is the official Federal Register notice for C-570-173?

The official Federal Register citation for C-570-173 is 2025-14213. The link is on this page; clicking it opens the canonical FR document on federalregister.gov, which carries the legally operative text — scope, rates, exclusions, and effective dates.

What is the companion case for C-570-173?

C-570-173 has a companion case at A-570-172. AD orders frequently run alongside a CVD order on the same product/country (or vice versa). Both deposits stack on top of base duties — importers pay the full sum of both rates at entry where both orders apply.
