Reading code 3911

The first two digits (39) place this code in chapter 39 — Plastics and Articles Thereof. 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.

Polymers, plastic sheets, pipes, packaging, and household plastic articles — one of the busiest chapters for traders and manufacturers, mostly at 18%.
