Most asbestos-containing articles face severe import restrictions under EPA's TSCA regulations. Crocidolite (blue asbestos) articles are subject to the strictest prohibitions. Any importer must file a TSCA certification and may need to demonstrate compliance with applicable rules or exemptions. Legal counsel and a licensed customs broker should be engaged before attempting importation.

Heading 6813 specifically covers friction materials — brake linings, clutch facings, and similar articles — whether or not they contain asbestos. Asbestos-containing friction materials that are unmounted classify under 681320 within 6813, not under 6812. Heading 6812 captures other fabricated asbestos articles, textiles, and clothing not covered by the more specific friction-material heading.
