5212.23.10 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category, 5212.23.10, specifically classifies dyed 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. This means the fabric is primarily cotton, but a significant portion of its weight is comprised of wool or other fine animal fibers, and it has undergone a dyeing process. These fabrics are considered "other" woven cotton fabrics, distinguishing them from more specific cotton fabric classifications.

Within this category, the distinction is made based on the preparation of the cotton component. The subcategories are 5212.23.10.10 for fabrics where the cotton is not combed, and 5212.23.10.20 for fabrics where the cotton has been combed. Combing is a process that aligns and removes short fibers from cotton, resulting in a smoother, stronger yarn, and therefore a fabric with different characteristics. The choice between these subcategories hinges on whether the cotton fibers used in the blend have undergone this preparatory combing step.
