6211.39.30.10 - Trousers (447)

This HTS classification, 6211.39.30.10, specifically covers men's or boys' trousers that are not knitted or crocheted, and are made from textile materials other than those specifically enumerated in preceding subheadings. The defining characteristic is the material composition; these trousers are constructed from wool or fine animal hair, distinguishing them from garments made of other natural or man-made fibers. The term "trousers" in this context refers to garments extending from the waist to the ankles, covering each leg separately.

The sibling category, 6211.39.30.20, encompasses "other" garments under the "Other garments, men's or boys': Of other textile materials: Other:" subheading. The key distinction lies in the specific material of the garment. While 6211.39.30.10 is exclusively for trousers made of wool or fine animal hair, the sibling category would include other types of garments (not trousers) or trousers made from different "other textile materials" that do not fall under wool or fine animal hair.

As this is a leaf node within the HTS classification system, there are no further subcategories to introduce. Classification at this level is final for trousers of wool or fine animal hair. For practical classification, customs officers will focus on verifying the material composition (wool or fine animal hair) and the garment type (trousers) to ensure accurate duty assessment.
