Chapter 73 classification notes
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.
