Serpentine Chrysotile Crude Lumps
Lump-form crude chrysotile asbestos from serpentine deposits, uncrushed and retaining natural ore structure without fiber extraction. HTS 2524.90.00.30 applies to this raw material stage for mills producing asbestos yarn or sheets. Particle size typically exceeds 50mm with visible rock matrix.

Import Tips & Compliance
• Lab test for asbestos type confirmation; chrysotile vs amphibole affects subheading
• File advance TSCA import certifications 14 days prior for asbestos minerals
Related Products under HTS 2524.90.00.30
Raw Chrysotile Asbestos Ore
Unprocessed chrysotile asbestos in its crude ore form, extracted directly from serpentine rock deposits, containing fibers embedded in host rock. Classified under HTS 2524.90.00.30 as crude chrysotile asbestos, not subjected to any mechanical separation, cleaning, or fiber extraction processes. Primarily used as feedstock for milling into fiber products.
Chrysotile Asbestos-Bearing Serpentine Rock
Natural serpentine rock formations containing embedded chrysotile asbestos fibers in crude, unseparated state from mining operations. Falls under HTS 2524.90.00.30 as crude chrysotile asbestos, distinguished by lack of fiber liberation or processing. Sourced from deposits in regions like Quebec or Russia for industrial fiber production.
Crude Chrysotile from Open-Pit Mining
Chrysotile asbestos crude extracted via open-pit methods, delivered as large ore fragments without screening or fiber opening. Specifically classified in HTS 2524.90.00.30 for unmilled chrysotile crudes used in downstream asbestos textile or friction material production. High rock content differentiates from purified fiber imports.
Unmilled Chrysotile Asbestos Rough
Rough, crude chrysotile asbestos material as mined, consisting of ore lumps with intact fiber veins not separated or carded. HTS 2524.90.00.30 covers this unprocessed form before milling into commercial fibers for reinforcement uses. Typical moisture content and rock matrix distinguish it from processed grades.
