Anthophyllite Asbestos Fiber
Anthophyllite is a less common amphibole asbestos mineral with moderate heat resistance, typically extracted as byproduct from talc deposits. It qualifies under HTS 2524.90.00.60 for other raw asbestos not statistically tracked separately. Applications include low-grade fillers and specialty refractories.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for industrial friction material preparation
Asbestos prepared specifically for brake linings or clutch facings classifies as worked millboard or felt.
If flux-calcined and flux-grade
Processed to chemical-grade purity shifts classification to felspar and similar fluxes.

Import Tips & Compliance
• Document mining origin; anthophyllite often co-occurs with talc requiring separation proof for Chapter 25 status
• Label packages with UN 2212 hazardous material designation per DOT/IMDG regulations
• Budget for specialized sampling; customs may require microscopic fiber identification

Chrysotile Asbestos Fiber
Chrysotile, the most common form of asbestos, is a naturally occurring silicate mineral fiber extracted from serpentine rock deposits. This white asbestos is classified under HTS 2524.90.00.60 as 'other' asbestos not specifically enumerated elsewhere in the heading. It is typically used in industrial applications requiring heat resistance.
Crocidolite Asbestos (Blue Asbestos)
Crocidolite, known as blue asbestos, is a rare amphibole mineral with high tensile strength and heat resistance, mined primarily in South Africa and Australia. It falls under HTS 2524.90.00.60 as 'other' asbestos types beyond the statistical breakout for unworked chrysotile. Historically used in high-performance insulation despite health risks.
Amosite Asbestos (Brown Asbestos)
Amosite, or brown asbestos, is an amphibole mineral valued for its durability and acid resistance, sourced from South African deposits. Classified in HTS 2524.90.00.60 as unspecified asbestos, it represents raw fiber separated from ore but not further processed. Used traditionally in pipe lagging and fireproofing.
Tremolite Asbestos Raw Splittings
Tremolite asbestos consists of magnesium-rich amphibole fibers separated from metamorphic rock formations. This raw material enters HTS 2524.90.00.60 as 'other' asbestos, distinguished from crude ore by mechanical fiber liberation but lacking further fabrication. Primarily destined for research or legacy industrial blending.
