HS code for Boys' swim shorts: 6112.31

Swimwear, men's or boys', of synthetic fibres, knitted or crocheted.

Classification of boys' swim shorts under HS 6112.31

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.

Codes often confused with 6112.31

Common mistake. 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.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
