6201.40.10.00 - Containing 15 percent or more by weight of down and waterfowl plumage and of which down comprises 35 percent or more by weight; containing 10 percent or more by weight of down (653)

This HTS classification specifically covers men's or boys' outerwear garments, such as overcoats, carcoats, capes, cloaks, anoraks, windbreakers, and similar articles, that are constructed from man-made fibers. A critical defining characteristic for classification under this code is the filling material: the garment must contain 15 percent or more by weight of down and waterfowl plumage, with down itself comprising at least 35 percent of that filling. Alternatively, it can be classified here if it contains 10 percent or more by weight of down, as indicated by the "(653)" notation, suggesting a specific regulatory note or further detail is associated with this threshold. These garments are distinguished from those of heading 6203, which typically refer to suits, ensembles, and separate garments for men and boys.

This particular subcategory falls under "Of man-made fibers" and further refines the "Overcoats, carcoats, capes, cloaks and similar coats" grouping. Its existence acknowledges that the presence and quantity of down and waterfowl plumage are key differentiators for specific types of outerwear, impacting duty rates and import regulations. The "Other:" sibling category at this level would encompass similar garments of man-made fibers that do not meet the stringent down and feather content criteria outlined here.

As this is a leaf node within the HTS, there are no further subdivisions to introduce. Classification is definitive based on the material composition (man-made fibers) and the specified thresholds for down and waterfowl plumage content. Examples of goods that would fall here include high-performance down-filled ski jackets, insulated anoraks, and heavy parkas designed for cold weather, provided they are made primarily from man-made fibers and meet the precise weight percentages for down and feather fill.
