SITCSection 6
U.S. imports of chromium oxide or chromium/chromium oxide-coated flat-rolled iron & nonalloy steel, 600mm wide or more (SITC 67442) totaled $18.1M in April 2026, traded with 13 countries.
Importers of Chromium Oxide or Chromium/Chromium Oxide-Coated Flat-Rolled Iron & Nonalloy Steel, 600mm Wide or More 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 or Chromium/Chromium Oxide-Coated Flat-Rolled Iron & Nonalloy Steel, 600mm Wide or More imports of $18.1M in April 2026 ran 33% below the year-to-date monthly average of $26.8M.
Last updated: April 2026 dataElectrolytic chromium-coated steel (ECCS) — also known commercially as tin-free steel (TFS) — is flat-rolled nonalloy steel coated with chromium metal and chromium oxides rather than tin, offering a cost-effective alternative to tinplate for can ends, easy-open lids, and aerosol components where lacquer adhesion and corrosion resistance are prioritized over solderability. The chromium and chromium-oxide dual-layer structure is the defining technical characteristic of this heading, distinguishing it from both tinplate and chrome-plated decorative steel. Section 232 tariffs apply, and importers should verify whether any antidumping or countervailing duty orders cover ECCS from the specific country of origin.

ECCS offers superior lacquer adhesion due to its chromium oxide surface layer, which bonds more effectively with organic coatings than tin. It is also generally lower in cost than tinplate because it uses less precious coating metal. The trade-off is that ECCS cannot be soldered, limiting its use to applications where mechanical seaming or adhesive bonding is used rather than soldered side seams.
ECCS/TFS has a very thin, functional chromium and chromium-oxide coating (measured in milligrams per square meter) applied for corrosion resistance and lacquer adhesion in packaging applications. Decorative chrome plating is a much heavier, bright-finish coating applied for aesthetic purposes and classified under articles-of-metal headings rather than flat-rolled steel. The mill certificate for ECCS will specify coating weight in mg/m² and reference packaging-grade standards, clearly distinguishing it from decorative plating.
