6203.39.10 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category, 6203.39.10, specifically classifies suit-type jackets and blazers for men and boys that are made of artificial fibers and contain 36 percent or more by weight of wool or fine animal hair. These garments are designed as part of suits or as standalone blazers, falling under the broader heading for men's and boys' suits and suit-type jackets. The defining characteristic is the blend of artificial fibers with a significant proportion of wool or fine animal hair, distinguishing them from garments made solely of artificial fibers or other textile materials.

It is important to differentiate this category from its sibling, 6203.39.20, which covers suit-type jackets and blazers of other textile materials that do not meet the wool or fine animal hair content requirement specified here, or are of mixed materials where artificial fibers are not the dominant component with the specified wool/hair blend.

Within this classification, further subdivisions exist to refine the classification. Subcategories 6203.39.10.10 and 6203.39.10.20 exist to provide more granular distinctions based on specific notes within the tariff schedule, likely relating to the intended use of the suit or other specific content criteria beyond the primary material composition. These subcategories allow for precise classification of garments based on detailed end-use or construction features.
