Reading code 3810

The first two digits (38) place this code in chapter 38 — Miscellaneous Chemical Products. 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.

Insecticides, disinfectants, biodiesel, and other chemical products and residuals not classified elsewhere.
