Classification of boys' synthetic knit shorts under HS 6103.43
Boys' synthetic knit shorts are classified under HS code 610343, which encompasses trousers, bib and brace overalls, breeches, and shorts for men or boys. The classification is driven by the material being synthetic fibres and the construction method being knitted or crocheted. Synthetic fibres, including polyester and elastane blends, are common in these garments due to their durability and stretch. Chapter 61 is the designated chapter for all knitted apparel. For a garment to be classified as "shorts" under this heading, it must be a lower-body garment that does not cover the knee, or covers it only partially, and is not designed as swimwear. The distinction between knitted and woven is the most critical factor here; if the shorts were made of a woven synthetic fabric, they would move to Chapter 62. Proper classification ensures compliance with international trade regulations and the application of appropriate duties. This code also includes garments that may be used for athletic purposes but do not meet the specific criteria for specialized sports equipment.

Codes often confused with 6103.43
Common mistake. A frequent misclassification occurs with HS code 620343, which is for woven synthetic shorts. Another common error involves HS code 6112, which covers tracksuits, ski suits, and swimwear. If the shorts are specifically designed and sold as swimwear (e.g., having an inner mesh liner and made of water-resistant material), they must be classified under 6112. Furthermore, if the shorts are part of a matching set sold together at retail, they should be classified as an ensemble under 610323. Confusion can also arise with 610349 if the synthetic content is not the predominant fibre by weight.

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).
