6103.10.90.40 - Subject to wool restraints (443)

This HTS category, 6103.10.90.40, covers men's or boys' knitted or crocheted suits made from textile materials other than cotton or man-made fibers, specifically those subject to wool restraints. These suits are characterized by their ensemble nature, typically comprising a jacket and trousers or shorts designed to be worn together as a matching outfit. The defining feature of this classification is the material content, which falls under wool restraints as indicated by the (443) indicator, distinguishing it from garments made with cotton or man-made fibers.

Unlike its sibling categories, 6103.10.90.50 which applies to suits subject to man-made fiber restraints, and 6103.10.90.80 which covers all other suits not subject to specific fiber restraints, this classification is exclusively for wool-based suits under specific import limitations. The "Other" designation at this level signifies that within the realm of non-cotton, non-man-made fiber suits, those subject to wool restraints are specifically itemized.

As a leaf node, this classification does not have further subcategories. Therefore, the classification hinges directly on the material composition (wool) and the presence of applicable restraints. Importers should ensure they are aware of and comply with any specific quantitative restrictions or documentary requirements associated with wool restraints when classifying goods under this HTS code.
