HS Code for Chlorite

Chlorite, in its natural mineral form, is classified under HS code 2530.10. This classification falls within Chapter 25, which covers salt, sulfur, earths and stone, plastering materials, lime, and cement. Heading 2530 is a residual heading for mineral substances not elsewhere specified or included. Subheading 2530.10 specifically groups vermiculite, perlite, and chlorites, provided they are unexpanded. Chlorite is a group of phyllosilicate minerals, often found in metamorphic rocks. According to the Chapter 25 notes, products of this chapter may be washed, crushed, ground, or screened, but they cannot be roasted, calcined, or mixed together. Therefore, natural chlorite that has undergone basic mechanical processing remains in 2530.10. This classification is distinct from chemical chlorites, which are manufactured salts of chlorous acid.

Products Included

• Natural chlorite mineral
• Unexpanded chlorite schist
• Chlorite-rich clay minerals
• Crushed or powdered natural chlorite

Common Misclassification

The most common misclassification is with HS code 2828.90, which covers chemical chlorites (like sodium chlorite). While they share a name, 2530.10 is for the natural earth mineral, while 2828.90 is for inorganic chemicals. Another error involves HS code 6806.20, which covers exfoliated (expanded) vermiculite and similar expanded mineral materials. If the chlorite has been heat-treated to expand, it moves from Chapter 25 to Chapter 68.
