Reading code 8409

The first two digits (84) place this code in chapter 84 — Machinery and Mechanical Appliances. 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.

The biggest goods chapter: engines, pumps, compressors, ACs, refrigerators, computers and laptops (8471), and industrial machinery of every kind.
