6812.80 - Of crocidolite:

This category, HTS 6812.80, specifically addresses fabricated asbestos fibers and mixtures with a basis of asbestos, including those with magnesium carbonate. It encompasses a wide range of articles manufactured from these asbestos-based materials, such as thread, woven fabric, clothing, headgear, footwear, and gaskets. The defining characteristic is the presence of crocidolite, a blue asbestos mineral, as a primary component in these goods. This heading excludes articles classified under heading 6811 or 6813, which may cover different forms of asbestos or asbestos-cement products.

Distinguishing this category from its sibling, "Other" (which would likely fall under a broader asbestos material classification), is the explicit mention of "crocidolite" as the specific type of asbestos fiber. This indicates a narrower focus on products where crocidolite is the dominant or defining asbestos component. The parent category, 6812, provides a broader framework for various asbestos-based articles, and this sub-heading isolates those specifically utilizing crocidolite for specialized applications or historical uses.

Within HTS 6812.80, further subdivision occurs to provide more granular classification. The subcategories, 6812.80.10.00 and 6812.80.90.00, differentiate based on the specific end-product. "Footwear" specifically captures any shoes or articles worn on the feet made from crocidolite-based materials, while the "Other" subcategory serves as a residual catch-all for all remaining crocidolite-based articles not explicitly defined elsewhere, ensuring comprehensive coverage under this crocidolite-specific heading.
