Heading

Reading code 2508

The first two digits (25) place this code in chapter 25 — Salt, Sulphur, Earths, Stone, Cement. 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.

Salt, natural stone, sand, gypsum, lime, and cement. Cement attracts the 28% slab — a major line item for construction businesses.
