6101.90.90.30 - Subject to man-made fiber restraints (634)

This HTS code, 6101.90.90.30, classifies knitted or crocheted overcoats, carcoats, capes, cloaks, anoraks, windbreakers, and similar outerwear for men and boys, specifically when made from "other textile materials" that are not cotton or wool. The critical defining characteristic for this subcategory is that the goods are subject to specific man-made fiber restraints, often indicated by a numerical suffix like (634) in the official tariff database, which dictates import limitations based on the origin of the material.

This classification is distinct from its siblings due to the material composition and associated trade restrictions. While 6101.90.90.10 covers similar garments subject to cotton restraints and 6101.90.90.20 pertains to those under wool restraints, this code specifically addresses articles made from man-made fibers. The sibling category 6101.90.90.60, "Other," would generally encompass knitted or crocheted outerwear under heading 6101 that does not fall under cotton, wool, or man-made fiber restraints.

As a leaf node, this classification does not have further subcategories. Therefore, accurate classification hinges on the precise identification of the textile material as a man-made fiber and confirmation that the garment is subject to the specific import restraints denoted for this code. Examples would include knitted anoraks or windbreakers crafted from polyester, nylon, or acrylic yarns, imported from countries where such limitations are in effect.
