6203.33.10.30 - For suits described in Note 3(a) (443)

This HTS classification covers men's suit-type jackets and blazers specifically designed for men, constructed from synthetic fibers. The defining characteristic of this category is that these garments must contain 36 percent or more by weight of wool or fine animal hair. This blend of materials, where synthetic fibers are present in significant quantities alongside wool or fine animal hair, is crucial for determining correct classification.

Distinguishing this category from its sibling, 6203.33.10.40 "Other," relies on the precise material composition. While both fall under suit-type jackets and blazers of synthetic fibers containing a substantial amount of wool or fine animal hair, this specific code is reserved for suits described in Note 3(a) (443). The sibling category would encompass other garments fitting the broader description but not meeting the specific criteria outlined in Note 3(a) (443).

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification under 6203.33.10.30 requires careful examination of the garment's material content to confirm the presence of synthetic fibers in conjunction with 36% or more wool or fine animal hair, and to ensure it aligns with the requirements of Note 3(a) (443). Examples would include men's blazers and suit jackets made from a blend of polyester and wool, where the wool content meets or exceeds the specified percentage.
