Legally operative description of covered merchandise from the Federal Register
C-580-910 is a U.S. countervailing duty (CVD) order on seamless carbon and alloy steel standard, line, and pressure pipe from South Korea, 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).
The country-wide cash deposit rate for C-580-910 is 1.78%. This rate applies to importers of non-listed manufacturers/exporters from South Korea. 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.
C-580-910 took effect on July 2, 2021 and is currently in active status — cash deposits apply at entry on every shipment in scope.
Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (37 flagged); and (2) the product's country of origin — this order applies to imports from South Korea. 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.
C-580-910 flags 37 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.
The official Federal Register citation for C-580-910 is 2021-18188. 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.
C-580-910 has a companion case at A-580-909. 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.
