The country-wide cash deposit rate for C-570-046 is 2.4%. 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.
C-570-046 took effect on December 1, 2022 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 (1 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.
