U.S. imports of chromium oxide-coated flat iron or nonalloy steel, 600mm or wider (HS 721050) totaled $18.1M in April 2026, traded with 13 countries.
Importers of Chromium Oxide-Coated Flat Iron or Nonalloy Steel, 600mm or Wider paid $9.0M in duties in April 2026 — an effective duty rate of 52% on $17.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Chromium Oxide-Coated Flat Iron or Nonalloy Steel, 600mm or Wider imports of $18.1M in April 2026 ran 33% below the year-to-date monthly average of $26.8M.
Last updated: April 2026 dataChromium-coated flat-rolled steel — including tin-free steel (TFS) used in food can ends and closures — is classified across three 10-digit lines under 7210.50, with 7210500020 covering a narrower width band (600–1050 mm) and 7210500090 capturing wider material. The chromium or chromium-oxide coating provides corrosion resistance and lacquer adhesion without the tin layer, making it a cost-competitive alternative to tinplate in certain packaging applications. Canada and Japan lead US supply, and all entries are subject to Section 232 tariffs.

Tin-free steel uses a chromium/chromium-oxide coating instead of tin, placing it under HTS 7210.50 rather than 7210.11 or 7210.12. The coating distinction is the classification driver. Commercially, TFS offers better lacquer adhesion and is often used for can ends and closures where direct food contact with the coating is limited, while tinplate remains preferred for can bodies requiring solderability.
The narrower width band in 7210500020 reflects a specific tariff line created to capture a commercially distinct width range — likely corresponding to standard coil widths used in particular packaging applications. Material outside that range but still within the heading falls into the NESOI line 7210500090. Importers should confirm the actual coil or sheet width on mill documentation to select the correct 10-digit line.
