2526 - Natural steatite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape; talc:

This HTS category, 2526, encompasses natural steatite and talc. Natural steatite, also known as soapstone, is a metamorphic rock characterized by its softness, smoothness, and greasy feel. This classification includes steatite that has been roughly trimmed or simply cut into blocks or slabs of a rectangular or square shape. Talc, a hydrous magnesium silicate mineral, is also covered here, whether in its raw form or processed into blocks or slabs.

Category 2526 is distinct from other mineral product classifications within Chapter 25. Unlike categories focused on basic minerals like salt or sulfur, or processed materials like lime and cement, this chapter specifically addresses natural stones and earths with particular properties. Its siblings, such as live animals in Chapter 01, are entirely unrelated and highlight the hierarchical structure of the HTS, moving from living organisms to inanimate mineral substances.

Within Category 2526, further subclassification is made based on the physical processing of the steatite or talc. Subcategory 2526.10.00.00 covers material that has not undergone crushing or powdering, meaning it remains in larger block or slab form. Conversely, 2526.20.00.00 is designated for steatite or talc that has been crushed or powdered, indicating a finer particle size suitable for different industrial applications. This distinction is crucial for determining the appropriate tariff treatment based on the commodity's readiness for use.
