5407.91.05 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category encompasses woven fabrics manufactured from synthetic filament yarn, where the fabric is specifically characterized by a substantial wool or fine animal hair content, comprising 36 percent or more by weight. These fabrics are classified under the broader heading for woven fabrics of synthetic filament yarn, further refined to "other woven fabrics" that do not fall into more specific categories based on their construction or yarn type. The primary defining characteristic here is the significant presence of wool or fine animal hair blended with synthetic filaments.

Distinguishing this subcategory from its sibling, 5407.91.10.00 ("Other"), is crucial. While both are classified as "Unbleached or bleached" and "Other woven fabrics," this specific node (5407.91.05) is exclusively for those fabrics where the blend with wool or fine animal hair is a defining characteristic and meets the minimum 36% threshold. The sibling category would encompass other "unbleached or bleached" woven fabrics of synthetic filament yarn that do not meet this specific wool/fine animal hair content criterion or are otherwise not specifically classified.

Within this category, a further distinction is made based on the processing of the wool or fine animal hair component. Subcategory 5407.91.05.10 covers fabrics where the wool or fine animal hair is "Not combed," meaning it has undergone less processing. Conversely, subcategory 5407.91.05.20 applies to fabrics where the wool or fine animal hair has been "Combed," indicating a more refined and potentially smoother yarn, influencing the final fabric's texture and appearance. This refinement level is a key differentiator for accurate classification within this group.
