6104.33 - Of synthetic fibers:

This category, HTS 6104.33, specifically covers women's or girls' suit-type jackets and blazers that are knitted or crocheted and made of synthetic fibers. These garments are designed for a formal or semi-formal look, forming part of a suit ensemble or worn as standalone blazers. The key defining characteristic is their construction from man-made fibers, such as polyester, nylon, or acrylic.

It's crucial to distinguish HTS 6104.33 from its siblings. While 6104.31 covers similar jackets and blazers made of wool or fine animal hair, and 6104.32 pertains to those constructed from cotton, this category focuses exclusively on synthetic materials. The subcategory 6104.39 addresses suit-type jackets and blazers made of *other* textile materials not specified in the preceding categories.

Within HTS 6104.33, further subdivisions exist to refine classification based on material composition. Subcategory 6104.33.10.00 applies to jackets and blazers containing 23 percent or more by weight of wool or fine animal hair, indicating a blended textile composition where synthetic fibers are predominant but animal fibers are present in a significant proportion. The remaining synthetic fiber suit-type jackets and blazers fall under the broader 'Other' subcategory, 6104.33.20.00.
