6203.41.30.10 - Men's (447)

This HTS category specifically classifies men's trousers made from worsted wool fabric, where the wool yarn used has an average fiber diameter of 18.5 microns or less. This precise definition focuses on the material quality and construction of the trousers, ensuring accurate tariff application for high-quality woolen garments. The "worsted" process refers to a method of preparing wool fibers for spinning, resulting in a smooth, strong yarn that gives the fabric a fine, crisp finish, and the low micron count indicates exceptionally fine wool, characteristic of premium apparel.

Distinguishing this category from its sibling, "Boys' (447)," is straightforward: this category exclusively applies to adult men's trousers, whereas the sibling covers similar garments for boys. The classification is therefore based on the intended wearer. As a leaf node, this category does not have further subcategories. Therefore, the primary focus for classification within this code remains on the stringent criteria of worsted wool fabric and the specified average fiber diameter of the constituent yarn, ensuring that only the most specific types of men's worsted wool trousers are captured here.
