Pick the subheading that describes your product. A subheading marked “n.e.c.” (not elsewhere classified) or “other” covers only what the subheadings before it do not. Click a code to copy it.
The first 6 digits are the same in every country that uses HS 2022. Each country adds 2–4 more digits and sets the duty in its own tariff, and the section and chapter notes can include or exclude products, so check the destination’s official tariff before you put the code on the invoice.

Can I write 1604 on a commercial invoice?
Customs usually need at least the 6-digit subheading (for example 1604.11), and the import declaration uses the destination country’s full code of 8 to 10 digits. Use the subheading that matches your product, and confirm the national digits with the buyer, the customs broker or the official tariff.
