5407.91.10.00 - Other (624)

This HTS classification, 5407.91.10.00, encompasses "Other" woven fabrics of synthetic filament yarn that are unbleached or bleached and are mixed mainly or solely with wool or fine animal hair. The key differentiator for this category is the presence of a significant proportion of wool or fine animal hair in combination with synthetic filament yarn, where the wool or fine animal hair constitutes less than 36 percent by weight. These fabrics are typically characterized by their construction from synthetic filaments and the inclusion of these natural animal fibers, resulting in a blend that influences their texture, drape, and insulation properties.

This classification is specifically distinct from its sibling category, 5407.91.05, which covers similar woven fabrics but requires the presence of 36 percent or more by weight of wool or fine animal hair. Therefore, 5407.91.10.00 applies to blends where the synthetic filament yarn is the dominant component by weight, and wool or fine animal hair is present in a lesser, though still significant, proportion. The "Other" designation at this level indicates that these fabrics do not fit into more specific subdivisions within the broader classification of woven fabrics of synthetic filament yarn, unbleached or bleached, mixed with wool or fine animal hair.

As a leaf node in the HTS structure, this category does not have further subcategories. Classification within 5407.91.10.00 relies on a precise determination of the weight percentage of wool or fine animal hair relative to the synthetic filament yarn. Importers and exporters must ensure that the composition of the woven fabric meets the criteria of being unbleached or bleached, primarily constructed from synthetic filament yarn, and containing less than 36 percent by weight of wool or fine animal hair to correctly assign this HTS code.
