5408.31.05 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category encompasses woven fabrics manufactured from artificial filament yarn, specifically those containing a significant proportion of wool or fine animal hair. According to the parent context, these are "Other woven fabrics" that are either "Unbleached or bleached" and "Mixed mainly or solely with wool or fine animal hair." The defining characteristic for classification within 5408.31.05 is the presence of 36 percent or more by weight of wool or fine animal hair within the fabric's composition.

Distinguishing this category from its sibling, 5408.31.10.00 (Other), is crucial for accurate classification. While 5408.31.10.00 would cover woven fabrics of artificial filament yarn that do not meet the specific wool or fine animal hair content threshold of 36 percent or more by weight, this category exclusively deals with those that *do*. The primary distinguishing factor, therefore, is the quantitative measure of wool or fine animal hair content.

Within this classification, further distinctions are made based on the processing of the wool or fine animal hair component. The subcategories 5408.31.05.10 and 5408.31.05.20 divide these fabrics based on whether the wool or fine animal hair has been "Not combed" or "Combed," respectively. This distinction relates to the preparation of the animal fibers prior to their incorporation into the yarn and subsequent weaving, impacting the final texture and appearance of the fabric.
