Products classified under Tariff item 2524.90.00
Actinolite Asbestos Raw Fiber
Actinolite asbestos raw fiber consists of green amphibole fibers extracted from metamorphic rock deposits, presented in raw unprocessed bundles. This product is in a crude state, having undergone only mechanical separation, and is not subjected to any processing beyond that permitted by Chapter 25 Note 1. It is classified under tariff item 2524.90.00 as 'other asbestos' since it is not a more specifically named type.
Amosite Asbestos Fibers
Amosite asbestos fibers are loose fibrous amosite asbestos separated from ore, with fiber lengths typically 1-5 cm, suitable for industrial blending. The product has undergone mechanical separation but is not further processed, remaining in a crude state. It is classified under tariff item 2524.90.00 as 'other asbestos' since amosite is not separately named in the tariff.
Amosite Asbestos Mine Concentrate
Amosite asbestos mine concentrate is concentrated amosite fibers from ore dressing processes, containing 70-90% amphibole content without chemical treatment. This intermediate crude form has undergone mechanical concentration (e.g., flotation or magnetic separation) which is permitted under Chapter 25 Note 1. It is classified under tariff item 2524.90.00 as 'other asbestos'.
Amosite Asbestos Ore
Amosite asbestos ore is a raw mineral ore containing long, coarse brown fibers of the amphibole mineral grunerite, sourced from mining operations. The product is in its natural state, not milled or processed beyond extraction, and is therefore classifiable as crude asbestos. It falls under tariff item 2524.90.00 as 'other asbestos' since amosite is not separately named in the tariff.
Amosite Asbestos Rock Fines
Amosite asbestos rock fines are crushed amosite-bearing rock containing amphibole fibers, with particle size under 2 mm, from mining operations. The product has undergone crushing and screening, which are mechanical processes permitted under Chapter 25 Note 1. It is classified under tariff item 2524.90.00 as 'other asbestos' since amosite is not specifically named.
Anthophyllite Asbestos Mineral
Anthophyllite asbestos mineral is a gray-brown amphibole asbestos occurring as cleavage fragments in raw ore, typically from deposits in Finland or the USA. The product is in a crude state, having undergone only mechanical extraction without further processing. It is classified under tariff item 2524.90.00 as 'other asbestos' because anthophyllite is not specifically named in the tariff schedule.
Chrysotile Asbestos-Bearing Serpentine Rock
Chrysotile asbestos-bearing serpentine rock is natural serpentine rock containing embedded chrysotile asbestos fibers in crude, unseparated state from mining operations. The product is in its crude state, not processed beyond extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'. It is not specifically named in the tariff.
Chrysotile Asbestos Fiber
Chrysotile asbestos fiber is a naturally occurring serpentine mineral fiber extracted from deposits in regions like Quebec or Russia. This raw fiber material is in a crude state, not milled or processed beyond initial extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'. It is the most common form of asbestos and is not separately named in the tariff.
Crocidolite Asbestos Rock
Crocidolite asbestos rock is a fibrous amphibole mineral mined primarily from South Africa and Australia, appearing as blue needle-like fibers in rock matrix. The product is in its crude state, not processed beyond extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'. However, crocidolite is specifically named in the tariff, so it may fall under a different tariff item if presented separately.
Crude Chrysotile from Open-Pit Mining
Crude chrysotile from open-pit mining is chrysotile asbestos crude extracted via open-pit methods, delivered as large ore fragments without screening or fiber opening. The product is in its crude state, not processed beyond extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'. It is not specifically named in the tariff.
Raw Amosite Asbestos Ore
Raw amosite asbestos ore is natural amosite asbestos ore extracted from deposits, consisting primarily of grunerite amphibole mineral in fibrous form. The product is in its crude state, not processed beyond extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'. It is not specifically named in the tariff, so it falls under the residual category.
Raw Chrysotile Asbestos Ore
Raw chrysotile asbestos ore is unprocessed chrysotile asbestos in its crude ore form, extracted directly from serpentine rock deposits, containing fibers embedded in host rock. The product is in its crude state, not subjected to any processing beyond extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'.
Serpentine Chrysotile Crude Lumps
Serpentine chrysotile crude lumps are lump-form crude chrysotile asbestos from serpentine deposits, uncrushed and retaining natural ore structure without fiber extraction. The product is in its crude state, not processed beyond extraction, and is classifiable under tariff item 2524.90.00 as 'other asbestos'.
Tremolite Asbestos Powder
Tremolite asbestos powder is a white amphibole mineral in powdered form, obtained by crushing and milling raw tremolite-actinolite deposits. The product has undergone mechanical processing (crushing and milling) which is permitted under Chapter 25 Note 1, but no chemical treatment or further processing has occurred. It is classified under tariff item 2524.90.00 as 'other asbestos' since tremolite is not specifically named.
Unpurified Amosite Asbestos Splittings
Unpurified amosite asbestos splittings are roughly split laminae of amosite asbestos from ore veins, not further processed beyond initial splitting. This mechanical process is permitted under Chapter 25 Note 1, and the product remains in a crude state. It is classified under tariff item 2524.90.00 as 'other asbestos'.
