6109.90.10.75 - Thermal undershirts (652)

This HTS classification, 6109.90.10.75, specifically covers thermal undershirts that are knitted or crocheted and made from man-made fibers. These garments are designed to provide an additional layer of insulation, often worn beneath other clothing to retain body heat. The key distinguishing factor for this subcategory is its primary function as a thermal garment.

While this category falls under the broader heading for T-shirts, singlets, tank tops, and similar knitted or crocheted garments of other textile materials, it is distinct from general-purpose T-shirts or tank tops. Unlike the sibling categories which may encompass a wider range of everyday tops, 6109.90.10.75 is precisely for items whose design and material composition are optimized for thermal regulation. The ".75" subheading signifies a specific type within the "Of man-made fibers" group for women's or girls' garments.

As this node is a leaf node, there are no further subdivisions. Therefore, the classification hinges on the precise identification of the garment as a thermal undershirt made of man-made fibers, intended for women or girls, and knitted or crocheted. Classification at this level requires careful examination of the item's construction and intended use to differentiate it from other similar knitwear.
