Reading code 2828

The first two digits (28) place this code in chapter 28 — Inorganic Chemicals. 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.

Industrial inorganic chemicals — acids, alkalis, oxides, and salts — plus compounds of precious and rare-earth metals.
