The first two digits (31) place this code in chapter 31 — Fertilisers. 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.
