6101.30 - Of man-made fibers:

This HTS category, 6101.30, specifically encompasses men's or boys' outerwear garments that are knitted or crocheted and primarily constructed from man-made fibers. These articles include a variety of items such as overcoats, carcoats, capes, cloaks, anoraks (including ski jackets), windbreakers, and similar protective or fashion outerwear. The defining characteristic here is the use of synthetic or artificial fibers as the predominant textile material.

Unlike its sibling category 6101.20, which covers similar garments made of cotton, or 6101.90 for other natural or man-made textile materials not specified, 6101.30 is exclusively for articles where man-made fibers are the principal component. This distinction is crucial for accurate customs declarations, as different textile compositions can trigger varying duty rates.

Within 6101.30, further subdivisions exist to refine the classification. The subcategory 6101.30.10.00 addresses items that, despite being primarily man-made fibers, also contain 25 percent or more by weight of leather. The subsequent "Other" category then covers all remaining knitted or crocheted men's or boys' outerwear of man-made fibers that do not meet the leather content threshold. This detailed breakdown ensures precise identification based on material composition.
