The importation of asbestos-containing articles is subject to EPA regulation under TSCA, which has progressively restricted the use and import of asbestos products. Importers must evaluate whether the specific article is covered by an EPA prohibition or reporting requirement before shipment. Given the complexity and evolving regulatory landscape, consultation with a licensed customs broker and environmental counsel is strongly advised before attempting entry.

This heading covers fabricated asbestos in textile or mixed forms — thread, woven fabric, clothing, and similar articles — but explicitly excludes asbestos-cement products (which are classified under cement-product headings) and asbestos friction materials (classified under 66382). The distinction matters because each category carries different regulatory treatment and classification criteria.
