6107.29.20.00 - Of wool or fine animal hair (459)

This HTS classification covers men's or boys' nightshirts and pajamas that are knitted or crocheted and made of textile materials other than those explicitly specified in sibling categories. The defining characteristic of this category is the primary textile composition. For instance, it would encompass garments made from materials like cotton, linen, synthetic fibers (e.g., polyester, nylon), or artificial fibers (e.g., rayon, modal), as long as they meet the general requirements of the parent heading.

It is crucial to distinguish this category from its siblings. Specifically, HTS code 6107.29.50.00 pertains to nightshirts and pajamas where silk or silk waste constitutes 70 percent or more by weight. Therefore, any garments not meeting this high silk content threshold, even if they contain some silk, would fall under this broader "other textile materials" classification. The distinction is based solely on the dominant material composition by weight.

As a leaf node, this classification does not have further subdivisions. The classification process for this category relies on identifying that the garment is a nightshirt or pajama, is knitted or crocheted, and its primary textile material does not fall into the specific silk category. The "of wool or fine animal hair" description provided at this node is an example of the specific material focus within the broader "other textile materials" grouping, indicating that such garments, when made from wool or fine animal hair, are classified here.
