Chapter 25 classification notes

Chapter 25 covers bulk industrial materials; most are duty-free under MFN. Specialty salts (Himalayan, Maldon) face the same tariff classification as industrial table salt.

Frequent misclassification in this chapter

Worked marble / granite goes to Chapter 68 (articles of stone) not 25; raw blocks stay in 25.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
