Reading code 8540

The first two digits (85) place this code in chapter 85 — Electrical Machinery and Electronics. 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.

Motors, transformers, batteries, mobile phones (8517), TVs, cables, switches, and LEDs — the electronics trade's home chapter.
