Reading code 7309

The first two digits (73) place this code in chapter 73 — Articles of Iron or Steel. As a 4-digit heading it groups a whole product family; 6 and 8-digit codes underneath it get more specific. Remember: you can never invent a shorter code by truncating a longer one — only codes that exist in the official tariff are valid.

Pipes and tubes, structures, fasteners, utensils, and every fabricated iron or steel article — one of the highest-traffic HSN chapters.
