Chrysotile Spinning Grade Milled Fibers
Chrysotile spinning grade milled fibers are group 3 asbestos fibers processed to a fine, fibrous consistency suitable for yarn spinning. The milling is a mechanical process that does not alter the mineral structure, keeping it within Chapter 25 as a product of the crude state or simple processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the fibers are in crude form, not milled
Crude asbestos is a separate heading from processed asbestos.
If the fibers are fabricated into yarn or fabric
Once spun into yarn, the product becomes an article of asbestos, classified in Chapter 68.

Import Tips & Compliance
• Verify that the milling process does not involve calcination or mixing, which would exclude it from Chapter 25
• Be aware of Canadian asbestos import restrictions and potential permits required
• Keep records of the fiber grade and processing to support classification
Related Products 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 (Brown Asbestos)
Amosite asbestos, also known as brown asbestos, is a raw amphibole mineral fiber prized for its durability and resistance to acids. Sourced from South African deposits, it is imported in a crude or processed state, such as crushed or fiberized, without undergoing roasting or calcination. This places it under tariff item 2524.90.00, which covers asbestos types not elsewhere specified.
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.
