5108.10.80.00 - Other (400)

This HTS classification, 5108.10.80.00, pertains to yarns of fine animal hair that have been carded but not combed, are not wound onto spools or presented in retail packaging, and do not fall under the specific categories of Angora rabbit hair or mohair. The "Other" designation signifies that it captures all remaining carded fine animal hair yarns not otherwise specified. This broadly includes yarns spun from the fine animal hair of sheep (excluding merino, which has its own specific classification), goats (excluding mohair), and potentially other fine animal hair sources when carded and prepared for manufacturing purposes.

Crucially, this category differentiates itself from its siblings by the material composition of the yarn. Specifically, 5108.10.30.00 covers carded yarns derived from Angora rabbit hair, while 5108.10.40.00 is for carded yarns made from mohair, which is a type of hair from the Angora goat. Therefore, 5108.10.80.00 serves as a residual category for other fine animal hair yarns meeting the carded, not combed, and not retail-ready criteria.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under this code hinges on confirming that the yarn is indeed made from fine animal hair, has undergone the carding process (a mechanical process that aligns fibers in a loose, parallel arrangement), has not been combed (a more intensive process that further straightens and separates fibers), and is intended for industrial or manufacturing use rather than direct sale to consumers.
