2524.10.00.00 - Crocidolite (Blue) 🖩

This HTS classification, 2524.10.00.00, specifically designates crocidolite, also known as blue asbestos. This fibrous mineral is characterized by its blue coloration and its specific crystalline structure. It falls within Chapter 25, which broadly covers salt, sulfur, earths, stone, and plastering materials, under Section V: Mineral Products. Crocidolite, like other forms of asbestos, is historically valued for its heat resistance and insulating properties, though its use is now heavily regulated due to health concerns.

This category is distinguished from its sibling, 2524.90.00 (Other), by its precise identification of crocidolite. The "Other" category would encompass any other forms of asbestos not specifically enumerated, such as chrysotile (white asbestos) or amosite (brown asbestos), based on their distinct mineralogical and physical properties. Therefore, classification into 2524.10.00.00 is determined by the definitive identification of crocidolite as the primary component.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is solely based on the definitive identification of the material as crocidolite. Customs officials will rely on laboratory analysis, physical characteristics (color, fiber morphology), and mineralogical identification to ensure accurate classification under this specific code, differentiating it from other asbestos types.
