Overview

This HTS category, 2509.00.10.00, specifically covers crude chalk. Crude chalk refers to naturally occurring calcium carbonate in a raw, unrefined state, typically mined directly from geological deposits. It is characterized by its chalky texture and generally white or off-white color. This classification is applied before any significant processing, such as grinding, purification, or formation into specific products.

Distinguishing this category from its sibling, 2509.00.20.00 "Other," is crucial. While both fall under the broader heading for chalk, this "Crude" classification is reserved for the raw, unprocessed material. The "Other" category would encompass chalk that has undergone some form of processing, such as being ground into powder, compacted, or treated for specific industrial applications, even if the material is still largely calcium carbonate.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification relies solely on identifying the material as naturally occurring, unrefined calcium carbonate. Examples of goods falling under this code would include mined chalk deposits still in their rough form, intended for further processing or direct use in applications where purity or specific particle size is not a primary concern.
