6112.19.10.40 - Women's or girls' (639)

This HTS classification, 6112.19.10.40, specifically covers women's or girls' shirts that are part of a track suit, and are knitted or crocheted from artificial fibers. These shirts, when classified under this subheading, are distinct from similar garments based on their intended use as a component of a track suit ensemble and their specific material composition. The "women's or girls'" designation is crucial, differentiating them from men's or boys' garments.

The "Of other textile materials" parent category indicates that these shirts are not made from cotton or synthetic fibers, but rather from artificial fibers like rayon or acetate. The preceding "Track suits" level confirms their inclusion within coordinated sets designed for athletic or leisure wear. This specific subheading serves as a detailed classification point for these women's and girls' track suit shirts.

As this is a leaf node, there are no further subcategories under 6112.19.10.40. Therefore, classification at this level is definitive for women's or girls' knitted or crocheted track suit shirts composed of artificial fibers. When classifying, it is important to verify the garment's intended use as part of a track suit and the precise fiber content to ensure accurate customs reporting.
