6103.23.00 - Of synthetic fibers

This HTS category, 6103.23.00, specifically classifies knitted or crocheted ensembles for men or boys that are composed of synthetic fibers. An ensemble, in this context, refers to a set of garments that are intended to be worn together as a coordinated outfit. The defining characteristic for inclusion in this subcategory is the primary textile material used in the construction of the ensemble, which must be synthetic fibers.

It is crucial to distinguish this category from its siblings. For instance, HTS code 6103.22.00 covers similar ensembles but exclusively when they are made of cotton. Ensembles classified under the broader 6103.29 heading would encompass those made from "other textile materials" not falling under cotton or synthetic fibers, such as silk, linen, or artificial fibers (excluding those derived from synthetic processes).

This node serves as a pathway to further refine the classification based on the presence of specific natural fibers. The subcategories provided indicate that within ensembles of synthetic fibers, a distinction is made between those containing 23 percent or more by weight of wool or fine animal hair, and "other" ensembles which would then consist solely or predominantly of synthetic fibers without significant quantities of wool or fine animal hair. This allows for precise tariff application based on the fiber composition of these coordinated clothing sets.
