Chrysotile (white asbestos) and other non-crocidolite asbestos varieties are classified here, with the US schedule distinguishing milled chrysotile fibers of spinning grade (2524900040), other chrysotile (2524900055), and a residual NESOI line (2524900000). EPA's TSCA framework governs admissibility, and the agency's final rule banning chrysotile asbestos effectively eliminates lawful commercial import pathways. Germany and China appear as recorded source countries in trade data, likely reflecting analytical samples or legacy shipments rather than active commercial flows.

Under TSCA, importers must file a TSCA certification with CBP at entry. Given EPA's ban on chrysotile, any import claim of a permissible use (e.g., a narrow research exemption) requires advance coordination with EPA's Office of Pollution Prevention and Toxics. Consult a licensed customs broker and environmental counsel before attempting any such shipment.
The distinction reflects fiber length and processing quality: spinning-grade chrysotile (Group 3 or equivalent) consists of longer, finer fibers suitable for textile or friction-material manufacturing, while shorter or lower-grade chrysotile was used in cement products and insulation. The separate tariff lines allow statistical tracking of fiber quality even though commercial trade has effectively ceased.
