5212.21.10 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS classification, 5212.21.10, pertains to unbleached woven cotton fabrics that weigh more than 200 grams per square meter and contain 36 percent or more by weight of wool or fine animal hair. These fabrics are specifically designated as "other" woven cotton fabrics, meaning they do not fall into more narrowly defined categories within Chapter 52. The key distinguishing factor for this subcategory is the significant presence of wool or fine animal hair alongside the cotton base.

Within the scope of "Other woven fabrics of cotton, weighing more than 200 g/m², Unbleached," this category is distinguished from its sibling, 5212.21.60, which covers any other unbleached woven cotton fabrics exceeding the weight threshold that do not meet the specific composition criteria of this heading. Therefore, the defining characteristic here is the blend of cotton with a substantial proportion of wool or fine animal hair.

The subcategories under 5212.21.10 further refine the classification based on the processing of the cotton component. 5212.21.10.10 applies to fabrics where the cotton has not been combed, retaining a coarser texture. Conversely, 5212.21.10.20 covers fabrics where the cotton has undergone a combing process, resulting in a finer, smoother yarn and a higher quality fabric. This distinction is crucial for determining the exact tariff treatment of these specialized woven cotton blends.
