Last updated: July 2026 dataNon-electrolytic zinc coatings — including hot-dip galvanizing and other thermal or chemical processes — applied to narrow flat-rolled iron or nonalloy steel strip are classified here, distinguishing them from the electrolytic process of heading 721220. The US schedule subdivides this heading by width (under 300 mm vs. 300–600 mm) and coil diameter, with tariff lines 7212301030, 7212301090, 7212303000, and 7212305000 capturing the principal commercial forms. The United Arab Emirates leads US import supply under this heading, an unusual sourcing pattern that can signal transshipment risk and warrants careful country-of-origin documentation.

CBP may request mill certificates, steel producer affidavits, and a detailed manufacturing process description to confirm that substantial transformation occurred in the declared country of origin. Given that the UAE is the leading declared supplier of this product, importers should be prepared for heightened scrutiny and should retain complete chain-of-custody records from the steel mill through the coating facility.
The US tariff lines under 721230 split first by width — under 300 mm versus 300 mm and above — and then by coil inside diameter (under or over 51 mm) and thickness for the narrower widths. Accurate measurement of the finished coil dimensions at the time of importation is essential to selecting the correct 10-digit HTS line.
