Using HTS 5403.39.90 correctly
A ten-digit HTS number has three parts: the four-digit heading, the six-digit international subheading shared by every WTO member, and the two-digit US statistical suffix. 5403.39.90 is a US national line — the same product may carry a different suffix in the EU TARIC or in another country's tariff.
Classification is determined by the General Rules of Interpretation, not by what the product is called on the invoice. If your goods could fall in two headings, GRI 1 sends you to the heading with the most specific description; GRI 3 breaks ties by essential character. A GRI 3(b) mistake is the single most common reason an entry gets reclassified and billed for unpaid duty plus interest.
