6108.39.10.00 - Of wool or fine animal hair (459)

This HTS category, 6108.39.10.00, specifically classifies knitted or crocheted women's or girls' nightdresses and pajamas that are exclusively or predominantly made from wool or fine animal hair. This includes garments such as sleep shirts, pajama tops, and pajama bottoms designed for sleepwear, provided the primary textile component by weight is wool or fine animal hair (e.g., cashmere, angora, mohair, alpaca).

This classification is distinguished from its sibling categories by its precise material composition. For instance, it is separate from 6108.39.40.00, which covers nightdresses and pajamas containing 70 percent or more by weight of silk or silk waste. It also differs from 6108.39.80.00, the "other" category, which would encompass nightdresses and pajamas made from textile materials not specified in the other subcategories of 6108.39. As this is a leaf node, there are no further subcategories. The defining characteristic for classification here is the presence of wool or fine animal hair as the principal constituent of the garment.
