Industrial Spinning Chrysotile Group 3 Milled Fibers
Industrial spinning chrysotile group 3 milled fibers are high-grade asbestos fibers processed for spinning into heat-resistant yarns. The milling is a mechanical operation that preserves the mineral's identity, placing it under tariff item 2524.90.00 as other asbestos.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the fibers are not milled and are in crude form
Crude asbestos is classified separately from milled asbestos.
If the fibers are spun into yarn
Spun yarn is an article of asbestos, not a raw mineral.

Import Tips & Compliance
• Document the milling process to show it is mechanical only, not chemical
• Be prepared for potential health and safety inspections due to asbestos content
• Verify if the product qualifies for any duty relief programs for industrial inputs
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.
