6106.90.30 - Other

This HTS category, 6106.90.30, encompasses women's or girls' blouses and shirts, knitted or crocheted, that are not made from wool, fine animal hair, or silk. The crucial differentiator here is the material composition; if the garment is primarily constructed from these specific fibers, it would fall under a different HTS subheading. This category serves as a catch-all for knitted or crocheted blouses and shirts made from any other textile materials, such as cotton, man-made fibers (like polyester, nylon, or rayon), or blends not predominantly of wool, fine animal hair, or silk.

The purpose of this broader classification is to provide a structured way to track trade in knitted or crocheted shirts and blouses based on their material origins, allowing for differentiated customs treatment and statistical reporting. It acts as a broader grouping before more specific sub-classifications are applied, which are often driven by import quotas, trade agreements, or other specific regulatory requirements.

Within this category, further distinctions are made based on potential trade restraints. The subcategories - 6106.90.30.10, 6106.90.30.20, and 6106.90.30.30 - indicate specific classifications for goods that are subject to cotton, wool, or man-made fiber restraints, respectively. The final subcategory, 6106.90.30.40, captures all remaining items within this "other textile materials" group that do not fall under those specific restraint categories. These subdivisions are critical for compliance with import regulations.
