6203.12 - Of synthetic fibers:

This HTS category, 6203.12, specifically covers suits for men or boys that are constructed primarily from synthetic fibers. Within the broader classification of men's or boys' suits, ensembles, and separates, this subheading narrows the focus to garments where synthetic fibers constitute the principal component by weight. These are formal or semi-formal attire designed for wear by men and boys, excluding swimwear.

It is crucial to distinguish this category from its siblings. HTS code 6203.11 pertains to suits made of wool or fine animal hair, while 6203.19 encompasses suits made from any other textile materials not falling under the previous two headings. Therefore, the defining characteristic of 6203.12 is the exclusive use or predominant presence of synthetic fibers in the suit's construction.

Under this heading, subcategories exist to further refine the classification based on the presence of other textile materials. Specifically, 6203.12.10.00 deals with suits containing a significant proportion (36% or more by weight) of wool or fine animal hair, indicating a blend where synthetic fibers are still dominant but wool or fine animal hair is also a substantial component. The remaining category, 6203.12.20, covers all other suits classified under 6203.12 that do not meet the specific criteria for wool or fine animal hair content outlined in the preceding subheading.
