6204.33.40 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category specifically covers suit-type jackets and blazers for women or girls that are of synthetic fibers and contain 36 percent or more by weight of wool or fine animal hair. The classification hinges on both the material composition of the garment, requiring a significant wool or fine animal hair content alongside synthetic fibers, and its intended use as a jacket or blazer within a suit ensemble.

It is crucial to distinguish this category from its siblings. While all fall under "Of synthetic fibers," the defining characteristic here is the high percentage of wool or fine animal hair. Sibling categories may cover garments with substantial silk or flax content (6204.33.10 and 6204.33.20 respectively), or those that do not meet the specific material requirements of this or the other sibling categories (6204.33.50). Therefore, precise weighing of the constituent fibers is essential for correct classification.

This category is further subdivided based on the intended wearer. The subcategories 6204.33.40.10 for "Women's" and 6204.33.40.20 for "Girls'" allow for a more granular classification, recognizing potential differences in sizing, cut, or styling that may distinguish apparel intended for adult women versus young girls. This distinction is important for trade statistics and specific import/export regulations.
