U.S. exports of Electrolytically Zinc-Plated Flat Iron or Nonalloy Steel, 600mm or Wider (HS 721030) totaled $5.8M in August 2026.
Importers of Electrolytically Zinc-Plated Flat Iron or Nonalloy Steel, 600mm or Wider paid $183K in duties in August 2026, an average duty rate of 50.66% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Electrolytically Zinc-Plated Flat Iron or Nonalloy Steel, 600mm or Wider imports of $361K in August 2026 ran 51% below the year-to-date monthly average of $742K.
Last updated: August 2026 dataElectrolytic galvanizing deposits a precisely controlled zinc layer on flat-rolled nonalloy steel, producing a smooth, paintable surface favored by automotive body panel and appliance manufacturers. The US schedule divides this heading between high-strength grades (7210300030) and standard grades (7210300060), a distinction that matters for automotive supply chains where advanced high-strength steel specifications are increasingly specified. Section 232 tariffs apply, and South Korea and Germany are the leading suppliers, with Japan and Mexico also significant.

Classification into the high-strength line requires the steel to meet specific yield or tensile strength thresholds defined in the HTS schedule notes. Mill test certificates showing mechanical properties (yield strength in MPa or ksi) are the primary documentation used to support the high-strength designation; importers should retain these for CBP review.
Electrolytically plated zinc (heading 7210.30) produces a thinner, more uniform coating applied in a continuous electroplating line, while hot-dip zinc coatings (headings 7210.41 and 7210.49) involve immersion in molten zinc and typically yield a thicker, spangle-patterned surface. The application method — not just the coating metal — determines which subheading applies.
