2517.41.00.00 - Of marble

This HTS category, 2517.41.00.00, specifically covers granules, chippings, and powder derived from marble, which falls under heading 2515. These materials are typically the result of processing marble, a metamorphic rock characterized by its crystalline structure and often distinctive veining. The key defining characteristic for classification here is the origin from marble.

This category is distinguished from its sibling, 2517.49.00.00, which encompasses "Other" granules, chippings, and powder of stones of heading 2515 or 2516. While 2517.41.00.00 is exclusively for marble-based products, the "Other" category would include similar processed forms of other stones classified under headings 2515 (which covers marble, travertine, and alabaster, and articles thereof) and 2516 (which covers granite, basalt, sandstone, and other monumental or building stone). Therefore, the specific mineral composition, in this case marble, is the critical factor for proper classification.

As a leaf node in the HTS classification, 2517.41.00.00 does not have further subcategories. Classification within this specific code depends entirely on the material being identifiable as derived from marble. This would include various sizes and finishes of marble powder, marble chips, or marble granules, regardless of whether they have undergone heat treatment. Their intended use, while often for concrete aggregates, road construction, or ballast, does not alter the classification as long as the base material is marble.
