EPA regulations under the Toxic Substances Control Act (TSCA) impose severe restrictions on asbestos-containing articles imported into the US. Most categories are effectively banned, and importers must be prepared to demonstrate compliance. CBP coordinates with EPA on admissibility, and shipments found to contain regulated asbestos forms may be refused entry or require destruction.

Millstones, grindstones, and grinding wheels of stone or agglomerated abrasives classify under heading 6804 in this chapter. Abrasive powders or grains applied to a textile, paper, or other flexible backing classify under 6805. Abrasive tools that are integral parts of a specific machine may be classified with that machine, but standalone abrasive articles generally remain in chapter 68.

Panels and boards made from vegetable fiber, straw, or similar materials bonded with cement, plaster, or other mineral binders fall under heading 6808. If the board is made from cellulose fiber cement without asbestos, it classifies in 6811. The distinction between 6808 and 6811 turns on whether the fiber component is vegetable/straw-based or a manufactured cellulose fiber; asbestos-cement articles also fall in 6811 but face the import restrictions noted above.
