CHAPTER

In plain English

This category covers dolomite that has been roughly trimmed or cut into rectangular blocks or slabs, regardless of whether it has been heated or not. The goods are split into two groups based on their treatment. One group includes dolomite that has not been calcined or sintered. The other group includes dolomite that has been calcined or sintered.

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.
