6203.41.30.20 - Boys' (447)

This HTS classification, 6203.41.30.20, specifically designates boys' trousers that are made from worsted wool fabric. The defining characteristic of this category is the wool yarn used, which must have an average fiber diameter of 18.5 microns or less. This specification ensures a finer texture and higher quality of the finished garment.

This category is distinct from its sibling, 6203.41.30.10, which covers men's trousers meeting the same material specifications. The primary differentiation lies in the intended wearer, with this code exclusively for boys' apparel. Therefore, when classifying trousers made of worsted wool fabric with the specified fiber diameter, the age and gender designation of the wearer are the critical factors for accurate classification.

As a leaf node in the HTS structure, this classification does not have further subdivisions. All trousers fitting the description of boys' garments made from worsted wool yarn with an average fiber diameter of 18.5 microns or less will fall directly under this code. Classification hinges on confirming the material composition, the worsted wool fabric, and the boys' sizing.
