6310.90.10.00 - Of wool or fine animal hair

This HTS category, 6310.90.10.00, specifically covers rags and scrap textile materials that are made *of wool or fine animal hair*. This includes items such as discarded woolen garments, worn-out carpets made from fine animal hair, or frayed remnants of textiles composed of these luxurious fibers. The key defining characteristic for classification under this heading is the primary material composition.

This category is distinguished from its sibling, 6310.90.20.00 ("Other"), by its exclusive focus on wool and fine animal hair. While the "Other" category would encompass rags and scrap materials made from cotton, synthetic fibers, or other textile materials not falling under the specific exclusion for wool and fine animal hair, this category is narrowly defined by its material content. Therefore, any article that is primarily composed of wool or materials like cashmere, alpaca, or angora would fall here, provided it meets the general description of rags or scrap textile articles.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level requires a careful assessment of the material composition of the worn or discarded textile article. It is crucial to confirm that the dominant textile fibers are indeed wool or fine animal hair to ensure correct entry under 6310.90.10.00.
