Chapter 73 classification notes

Heavily subject to trade defense measures. US Section 232 tariffs (25%) apply to most steel imports. EU safeguard quotas in effect. Anti-dumping duties common on Chinese, Indian, and Turkish steel.

Frequent misclassification in this chapter

Stainless steel articles should be classified under the specific stainless steel headings, not general iron/steel. Alloy steel has its own subheadings.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
