Reading code 903190

The first two digits (90) place this code in chapter 90 — Optical, Medical, and Precision Instruments. Heading 9031 groups the product family, and the remaining digits pin down this specific 6-digit classification. 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%.
