Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If actinolite/tremolite asbestos
Other amphibole asbestos types like actinolite have separate statistical reporting codes.
If non-agglomerated chemical preparations
Prepared chemical additions of asbestos shift to Chapter 38 chemical products.
If incorporated into refractory bricks
Refractory bricks containing asbestos are classified by end ceramic product form.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Include XRF spectrometry reports verifying amosite mineralogy to distinguish from tremolite/actinolite
• Budget for bonded warehouse storage as direct release prohibited without EPA approval
• Train customs brokers on asbestos statistical suffixes to prevent erroneous Chapter 25 entries

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.
