No — the HTS classification under 7210610000 is based on the coating composition (aluminum-zinc alloy) and physical form, not the brand name. Whether the product is sold as Galvalume, Zincalume, or an unbranded equivalent, it falls under the same tariff line provided it meets the coating specification. Brand documentation may be relevant for licensing or quality purposes but does not affect customs classification.
Both Taiwan and South Korea have been named in antidumping and countervailing duty proceedings covering certain coated flat-rolled steel products in the US market. Importers should verify the current status of any active orders or suspension agreements with the Department of Commerce and CBP before placing orders, as scope and duty rates can change following administrative reviews.
