Overview

This HTS category, 2530.90.10.00, specifically classifies natural cryolite and natural chiolite. These are naturally occurring fluoride minerals that are primarily composed of sodium aluminum fluoride. They are characterized by their crystalline structure and are sought after for their unique chemical properties, particularly in the production of aluminum.

Distinguishing this category from its siblings, 2530.90.20.00 covers natural micaceous iron oxides, which are iron oxides with a flaky or platy structure, distinct from the crystalline fluoride composition of cryolite and chiolite. The remaining sibling category, 2530.90.80, encompasses all other mineral substances not elsewhere specified or included within Chapter 25, that do not fall under the specific definitions of cryolite, chiolite, or micaceous iron oxides.

As this is a leaf node, there are no further subcategories under 2530.90.10.00. Classification within this code relies on the definitive identification of the material as naturally occurring cryolite or natural chiolite, based on its mineralogical composition and origin. Exclusions would include synthetic cryolite or chiolite, which are classified elsewhere.
