6203.33 - Of synthetic fibers:

This HTS category, 6203.33, specifically covers suit-type jackets and blazers for men or boys that are made predominantly or entirely from synthetic fibers. These garments are designed to be part of a suit ensemble or are blazers intended for formal or semi-formal wear. The classification hinges on the primary textile material being synthetic, aligning with the broader scope of Chapter 62 for non-knitted or crocheted apparel.

Distinction from sibling categories is based solely on fiber content. While 6203.31 falls under wool or fine animal hair, and 6203.32 under cotton, 6203.33 is reserved for articles where synthetic fibers constitute the principal component. Category 6203.39 encompasses suit-type jackets and blazers made from other textile materials not otherwise specified.

Within 6203.33, further subclassification is provided to differentiate based on the presence of other fibers. Subcategory 6203.33.10 is for garments containing 36 percent or more by weight of wool or fine animal hair, indicating a blended composition where synthetic fibers still dominate but with a significant wool component. The residual category, 6203.33.20, covers all other suit-type jackets and blazers made of synthetic fibers that do not meet the criteria for the 6203.33.10 subcategory.
