6117.90.90.20 - Of cotton (339)

This HTS category, 6117.90.90.20, specifically covers knitted or crocheted parts of blouses and shirts that are made of cotton. These parts would include elements such as collars, cuffs, plackets, or even entire sleeves that are intended for incorporation into cotton blouses or shirts. The key defining characteristic is the material composition being 100% cotton, and the fact that these are discrete components designed to be assembled into the final garment.

When classifying parts of blouses and shirts, it is crucial to differentiate based on material. This category, "Of cotton," stands distinct from its siblings: "Of wool or fine animal hair" (6117.90.90.25), which applies to parts made from these animal fibers; "Of man-made fibers" (6117.90.90.30), for parts made from synthetic or artificial fibers; and "Other" (6117.90.90.35), which serves as a residual category for parts composed of materials not otherwise specified. The determination of whether a part is primarily of cotton will dictate its placement within this specific sub-heading.

As this is a leaf node within the HTS structure, there are no further subdivisions under 6117.90.90.20. Therefore, the classification hinges solely on confirming that the knitted or crocheted part is indeed intended for a blouse or shirt and is predominantly composed of cotton fibers. This ensures accurate tariff application based on the finished garment's primary textile material.
