6203.43.13.40 - Other (647)

This HTS classification covers boys' shorts made from synthetic fibers, specifically those not fitting into more narrowly defined categories. These shorts are intended for general wear rather than specialized athletic performance, differentiating them from categories of recreational performance outerwear. The "Other" designation indicates a residual category for boys' synthetic shorts that do not meet the criteria for specific sub-classifications within Chapter 6203.

This category is distinct from its sibling, 6203.43.13.35, which is specifically designated for shorts imported as parts of playsuits. While both are boys' shorts of synthetic fibers, the critical distinction lies in their intended use and import context; this category captures standalone shorts not associated with a playsuit ensemble.

As this is a leaf node, there are no further subcategories. Classification at this level relies on the absence of specific characteristics that would place the shorts into more precise subheadings, such as those for specialized functions or specific types of outerwear. Therefore, the primary determinant for classification here is that the shorts are for boys, made of synthetic fibers, and do not fall under any other more specific description within the boys' shorts category.
