SITCSection 6
U.S. imports of zinc-plated or coated flat-rolled iron & nonalloy steel (nes), 600mm wide or more (SITC 67413) totaled $44.7M in April 2026, traded with 27 countries.
Importers of Zinc-Plated or Coated Flat-Rolled Iron & Nonalloy Steel (NES), 600mm Wide or More paid $18.3M in duties in April 2026 — an effective duty rate of 50% on $36.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataZinc-coated flat-rolled nonalloy steel in widths of 600 mm or more that does not qualify as electrolytically plated — including hot-dip galvanized, zinc-alloy coated (such as Galvalume or Galfan), and other non-electrolytic processes — falls under this residual 'not elsewhere specified' heading. Hot-dip galvanized wide coil is a dominant input for roofing, structural framing, and HVAC ductwork in the US construction sector. Section 232 tariffs apply broadly, and antidumping or countervailing duty orders on hot-dip galvanized steel from several origins are active, making supplier-origin verification a critical pre-import step.

The NES heading captures all zinc-coating methods other than electrolytic deposition — most importantly hot-dip galvanizing, as well as zinc-alloy coatings like Galvalume (zinc-aluminum) and Galfan (zinc-aluminum-magnesium). The coating process must be identified on the mill certificate; if the certificate is ambiguous, the importer should obtain a written process confirmation from the mill to support the correct classification.
Active antidumping and countervailing duty orders on hot-dip galvanized flat-rolled steel exist against multiple countries of origin. Importers should query the CBP ADD/CVD portal and USITC order database by specific origin before shipment, as scope rulings and suspension agreements can change the duty liability significantly.
