5515.22.05 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category, 5515.22.05, covers woven fabrics manufactured from synthetic staple fibers, specifically those containing a significant proportion of wool or fine animal hair, at 36 percent or more by weight. These fabrics are distinct from other synthetic staple fiber woven fabrics due to this substantial inclusion of natural animal fibers. The classification emphasizes the material composition as the primary determinant for inclusion.

Within the broader group of "Other woven fabrics of acrylic or modacrylic staple fibers" and further refined as "Mixed mainly or solely with wool or fine animal hair," this specific code distinguishes fabrics based on the processing of the wool or fine animal hair component.

The subcategories under 5515.22.05 differentiate based on whether the wool or fine animal hair has undergone a combing process. Category 5515.22.05.10 applies to fabrics where the animal hair is not combed, while category 5515.22.05.20 covers fabrics where the animal hair has been combed. This distinction in fiber preparation impacts the final texture, appearance, and quality of the woven fabric, and is a key factor for precise tariff classification.
