Legally operative description of covered merchandise from the Federal Register
C-523-816 is a U.S. countervailing duty (CVD) order on aluminum foil from Oman, 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-523-816 is 2.15%. This rate applies to importers of non-listed manufacturers/exporters from Oman. 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-523-816 took effect on September 9, 2025 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 (17 flagged); and (2) the product's country of origin — this order applies to imports from Oman. 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-523-816 flags 17 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-523-816 is 2021-24858. 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-523-816 has a companion case at A-523-815. 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.
