6103.41 - Of wool or fine animal hair:

This HTS category, 6103.41, specifically covers men's or boys' trousers, bib and brace overalls, breeches, and shorts that are knitted or crocheted and made from wool or fine animal hair. This distinction is crucial for accurate customs declaration, as it requires the primary fiber content to be derived from sheep's wool, cashmere, mohair, alpaca, llama, vicuña, or similar valuable animal fibers.

Unlike sibling categories such as 6103.42 (cotton) or 6103.43 (synthetic fibers), the defining characteristic here is the material composition. Goods classified under 6103.41 must predominantly consist of wool or fine animal hair to be correctly identified. This category falls under the broader classification of men's or boys' knitted or crocheted garments, specifically those in the lower body apparel and workwear segments.

Within 6103.41, further subdivisions exist to refine classification. Subcategory 6103.41.10 encompasses trousers, breeches, and shorts made from wool or fine animal hair, while 6103.41.20.00 specifically addresses bib and brace overalls constructed from these same luxurious fibers. These subcategories allow for more granular reporting and potential tariff differentiation based on the specific garment type.
