Unroasted iron pyrites
1 declarable lines
Heading 2502 covers unroasted iron pyrites, the iron sulfide mineral mined in crude form and mainly used to make sulfuric acid or recover sulfur. The heading has a single declarable line, 2502.00.00.00, so there is no subheading split based on form, purity or use. Once the pyrites are roasted or burned, they leave this heading.

How to choose the right subheading
- Confirm the material is iron pyrites (iron sulfide mineral), not a copper or other metal ore.
- Confirm the pyrites are unroasted and have not been burned, sintered or heat-treated.
- Confirm the goods are crude mineral, whether lump, crushed or fine, and not a downstream chemical.
- Check for any precious metal content or blending that would move the goods to a different chapter.
