Reading code 2912

The first two digits (29) place this code in chapter 29 — Organic 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.

Bulk organic chemicals and intermediates, including the API building blocks of India's pharmaceutical industry.
