6103.39.80.30 - Subject to man-made fiber restraints (633)

This HTS classification, 6103.39.80.30, specifically designates men's or boys' suit-type jackets and blazers, knitted or crocheted, that are constructed from "other textile materials" and are subject to specific man-made fiber restraints. These restraints are a crucial determinant for classification under this heading, indicating that the fabric composition primarily involves man-made fibers, such as polyester, nylon, or acrylic, and that quotas or other trade limitations may apply to these materials. The garments classified here are typically designed for formal or semi-formal wear, characterized by their tailored construction and resemblance to traditional suit jackets.

This category is distinguished from its sibling categories by the nature of the textile material and the applicable restraints. Specifically, 6103.39.80.10 covers garments subject to cotton restraints, while 6103.39.80.20 pertains to those under wool restraints. The "Other" sibling category, 6103.39.80.60, would encompass similar knitted or crocheted suit-type jackets and blazers made from "other textile materials" that are not subject to these specific man-made fiber, cotton, or wool restraints, or are subject to different, less restrictive trade measures.

As a leaf node, 6103.39.80.30 does not have further subcategories. Therefore, the precise classification hinges on confirming the garment's knitted or crocheted construction, its suitability as a suit-type jacket or blazer, and critically, that its man-made fiber content aligns with the specific trade restraints referenced by the code (633). Importers must carefully verify the fiber composition and consult relevant trade agreements or U.S. Customs and Border Protection (CBP) guidance to ensure accurate application of these restraints.
