Crocidolite Asbestos Rock
Crocidolite, or blue asbestos, is a fibrous amphibole mineral mined primarily from South Africa and Australia, appearing as blue needle-like fibers in rock matrix. Classified under HTS 2524.90.00 as 'other asbestos,' it is the most hazardous form due to its carcinogenicity. Historically used in insulation but now strictly controlled.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crude or unworked state resembling pebbles
Chapter notes prioritize heading 2517 for unworked pebbly rocks; asbestos in crude form may shift there if not distinctly fibrous.
If made into asbestos-cement sheets
Combinations of asbestos with cement for construction materials are classified under fabricated articles of Chapter 68.
If prefabricated asbestos panels
Articles like asbestos-cement pipes or sheets are specifically covered in heading 6811.

Import Tips & Compliance
• Secure special permits from customs and environmental agencies; crocidolite faces additional WHO/IARC restrictions
• Label shipments as 'carcinogenic material' per UN dangerous goods regulations (Class 9)

Chrysotile Asbestos Fiber
Chrysotile, the most common form of asbestos, is a naturally occurring serpentine mineral fiber extracted from deposits in regions like Quebec or Russia. This raw fiber material is classified under HTS 2524.90.00 as 'other asbestos' not specifically enumerated elsewhere in heading 2524. It is used in industrial applications requiring heat resistance, though imports are heavily regulated due to health risks.
Amosite Asbestos Ore
Amosite, or brown asbestos, is an amphibole mineral ore containing long, coarse brown fibers, sourced from South African mines. It falls under HTS 2524.90.00 as 'other asbestos' in its raw ore form before milling. Known for acid resistance, formerly used in chemical plant linings.
Tremolite Asbestos Powder
Tremolite asbestos is a white amphibole mineral in powdered form, obtained by crushing and milling raw tremolite-actinolite deposits. Classified under HTS 2524.90.00 as 'other asbestos' when not further processed. Used in specialty fillers despite regulations.
Actinolite Asbestos Raw Fiber
Actinolite asbestos consists of green amphibole fibers from metamorphic rock deposits, typically in raw unprocessed bundles. It is categorized under HTS 2524.90.00 as unspecified 'other asbestos.' Less common but shares similar regulatory burdens.
Anthophyllite Asbestos Mineral
Anthophyllite is a gray-brown amphibole asbestos mineral occurring as cleavage fragments in raw ore from Finland or USA deposits. Classified as HTS 2524.90.00 'other asbestos' in crude state. Rarely imported due to low commercial value.
