A-549-840 took effect on December 13, 2019 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 (5 flagged); and (2) the product's country of origin — this order applies to imports from Thailand. 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.
