6203.39.90.30 - Subject to man-made fiber restraints (633)

This HTS category, 6203.39.90.30, specifically classifies men's or boys' suit-type jackets and blazers that are not knitted or crocheted, and are made from "other textile materials" beyond cotton or wool. The key defining characteristic for this sub-classification is that the garments are subject to man-made fiber restraints, indicated by the reference (633). These restraints are crucial for import and export compliance, often related to trade agreements or quotas.

This category distinguishes itself from its siblings by its material composition and the specific restraints applied. While 6203.39.90.10 covers similar garments subject to cotton restraints and 6203.39.90.20 covers those under wool restraints, this category specifically addresses articles made predominantly or entirely of synthetic or man-made fibers, such as polyester, nylon, or rayon, when such fibers are subject to specific trade limitations. The residual category, 6203.39.90.60, covers similar jackets and blazers made from other textile materials not falling under cotton, wool, or man-made fiber restraints.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification within 6203.39.90.30 depends solely on the accurate identification of the garment as a men's or boys' suit-type jacket or blazer, its construction from textile materials other than cotton or wool, and crucially, that it is subject to the specified man-made fiber restraints. Importers and exporters must consult the relevant trade regulations and tariff schedules to confirm the applicability of these restraints for accurate customs declaration.
