HS Code for Boys' swim shorts

HS code 6112.31 is designated for men's or boys' swimwear that is manufactured using knitting or crocheting techniques and is composed of synthetic fibers such as polyester, nylon, or elastane blends. The classification is primarily driven by the garment's intended use as swimwear and its construction method. Knitted fabrics are characterized by interlocking loops of yarn, providing the stretch and recovery necessary for athletic swimwear. For a product to be classified here, it must be clearly identifiable as swimwear by its cut, fabric, and lack of features typical of ordinary shorts, such as a functional fly or non-elasticated waistbands. Synthetic fibers are preferred in this category due to their low water absorption and durability in chlorinated or salt water. This code excludes swimwear made of natural fibers or woven fabrics, which are classified elsewhere in the nomenclature. The presence of a high percentage of elastane (spandex) is a common indicator of products falling under this knitted synthetic category.

Common Misclassification

The most common misclassification occurs with HS code 6211.11, which covers woven swimwear. If the fabric is woven (interlaced warp and weft) rather than knitted, it must be moved to Chapter 62. Another common error is classifying these as general shorts under 6103.43; however, if the garment has a mesh liner and is made of water-resistant synthetic knit, 6112.31 takes precedence as a more specific heading.
