6203.39.10.10 - For suits described in Note 3(a) (443)

This classification pertains to men's or boys' suit-type jackets and blazers crafted from artificial fibers, specifically those containing 36 percent or more by weight of wool or fine animal hair. These garments are designed as part of a suit or ensemble and are not knitted or crocheted. The presence of a substantial wool or fine animal hair content, meeting or exceeding the 36% threshold by weight, is the defining characteristic for inclusion in this specific subcategory.

Distinguishing this category from its sibling, 6203.39.10.20 "Other," hinges on the precise material composition. While both are suit-type jackets and blazers of artificial fibers, this classification is exclusively for those with a significant wool or fine animal hair component. The sibling category would encompass jackets and blazers made from artificial fibers where the wool or fine animal hair content is less than 36% by weight.

As this classification represents a terminal node within the HTS structure, there are no further subcategories to introduce. Therefore, classification within 6203.39.10.10 is final based on the established criteria of garment type, textile material (artificial fibers), and the specific minimum percentage of wool or fine animal hair by weight.
