Last updated: April 2026 dataAluminum-zinc alloy coatings — commercially known as Galvalume or Zincalume — combine zinc's galvanic protection with aluminum's barrier resistance, producing a flat-rolled product widely used in metal roofing, building panels, and appliance back panels. Classified under a single line, 7210610000, this product is subject to Section 232 tariffs and has historically been the subject of antidumping proceedings from multiple origins. Taiwan and South Korea are the leading US suppliers, with Indonesia and New Zealand also present in the import stream.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
