Reading code 1004

The first two digits (10) place this code in chapter 10 — Cereals. 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.

Wheat, rice, maize, barley, and other cereals. Unbranded cereals are exempt; pre-packaged and labelled cereals attract 5% GST.
