Products classified under HTS 2524.90.00.10
Raw Amosite Asbestos Ore
Natural amosite asbestos ore extracted from deposits, consisting primarily of grunerite amphibole mineral in fibrous form. Classified under HTS 2524.90.0010 as amosite, a specific type of asbestos other than crocidolite, in its raw unprocessed state. Used historically in insulation and fireproofing materials before regulatory bans.
Amosite Asbestos Fibers
Loose fibrous amosite asbestos separated from ore, with fiber lengths typically 1-5 cm, suitable for industrial blending. Falls under HTS 2524.90.0010 as unprocessed amosite asbestos distinguished from other amphibole types. Historically applied in cement reinforcement and friction materials.
Amosite Asbestos Rock Fines
Crushed amosite-bearing rock containing amphibole fibers, particle size under 2 mm, from mining operations. HTS 2524.90.0010 applies to this crude form of amosite asbestos as defined in the asbestos heading. Intended for specialized processing or geological study.
Unpurified Amosite Asbestos Splittings
Roughly split laminae of amosite asbestos from ore veins, not further processed beyond initial splitting. Specifically identified as amosite under HTS 2524.90.0010 within the 'other' asbestos category excluding crocidolite. Used in legacy applications like high-temperature gaskets.
Amosite Asbestos Mine Concentrate
Concentrated amosite fibers from ore dressing processes, containing 70-90% amphibole content without chemical treatment. HTS 2524.90.0010 covers this intermediate crude form of amosite asbestos. Primarily for historical industrial or research utilization.
