Reading code 9020

The first two digits (90) place this code in chapter 90 — Optical, Medical, and Precision Instruments. 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.

Medical and surgical instruments, diagnostic equipment, meters, lenses, and precision instruments — much of it at concessional 12%.
