Last updated: April 2026 dataHot-dip galvanized corrugated sheet — classified under 7210410000 — is a construction staple for roofing, wall cladding, and agricultural buildings, where the corrugated profile adds structural rigidity and the zinc coating provides long-term corrosion protection. Section 232 tariffs apply, and antidumping or countervailing duty orders on galvanized steel from certain origins may also be relevant depending on supplier. South Korea and Costa Rica lead US imports under this subheading, with Mexico, China, and India also present.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Flat-rolled steel products from China have been subject to antidumping and countervailing duty orders covering various galvanized steel categories. Importers should check the current scope of any active AD/CVD orders with CBP or the Department of Commerce before importing, as scope rulings can determine whether a specific corrugated product is covered.
Mill test certificates and product data sheets that specify the coating process and coating weight (in g/m² per side) are the standard supporting documents. Hot-dip coatings are generally identified by spangle appearance and heavier coating weights, while electrolytic coatings are smoother and lighter. CBP may request these records to verify the correct subheading.
