6103.39.80.20 - Subject to wool restraints (433)

This HTS category, 6103.39.80.20, specifically classifies knitted or crocheted men's or boys' suit-type jackets and blazers made from textile materials other than those primarily composed of cotton, man-made fibers, or wool subject to specific restraints. These garments are designed to be part of a suit ensemble or can be worn as blazers, falling under the broader umbrella of men's or boys' suits and suit-type jackets. The "other textile materials" designation is key here, meaning materials not explicitly covered by cotton or man-made fiber classifications at this level.

This particular classification is distinguished from its siblings by its specific application of wool restraints, indicated by the "(433)" notation. While 6103.39.80.10 covers items subject to cotton restraints, and 6103.39.80.30 deals with man-made fiber restraints, this code applies when wool is a component and falls under a defined restraint program. The sibling category 6103.39.80.60 serves as a residual for items of "other textile materials" not subject to these specific restraint conditions.

As this is a leaf node, there are no further subcategories within 6103.39.80.20. Classification at this point relies on the accurate identification of the textile material composition and the presence of applicable wool restraints. Importers and exporters should consult the specific tariff schedule for the exact definition and scope of the wool restraint program referenced to ensure correct classification.
