U.S. imports of electrolytically zinc-plated flat iron or nonalloy steel, 600mm or wider (HS 721030) totaled $1.3M in April 2026, traded with 7 countries.
Importers of Electrolytically Zinc-Plated Flat Iron or Nonalloy Steel, 600mm or Wider paid $643K in duties in April 2026 — an effective duty rate of 50% on $1.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Electrolytically Zinc-Plated Flat Iron or Nonalloy Steel, 600mm or Wider imports of $1.3M in April 2026 ran 45% above the year-to-date monthly average of $888K.
Last updated: April 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.
