2509.00.20.00 - Other

This HTS category, 2509.00.20.00, encompasses "Other" chalk. It specifically refers to chalk that does not fit the definition of crude chalk. This typically includes chalk that has undergone some degree of processing or refinement beyond its natural state but prior to being shaped into specific forms like sticks or blocks for writing. Examples might include finely powdered chalk, chalk that has been screened or sifted to remove impurities, or chalk that has undergone minor chemical treatment for purification.

The key distinction between this category and its sibling, 2509.00.10.00 (Crude), lies in the level of processing. Crude chalk is generally understood as chalk extracted directly from the earth with minimal or no intervention. This category, however, covers chalk that has been subjected to operations that alter its physical form or purity, making it distinct from the raw, unadulterated mineral.

As this is a leaf node within the HTS classification, there are no further subcategories. Therefore, the classification criteria for 2509.00.20.00 rely entirely on differentiating it from "Crude" chalk based on the extent of any processing or refinement applied to the chalk mineral.
