What HS 6103.43 covers

This HS code covers men's and boys' knitted or crocheted trousers, shorts, breeches, and bib and brace overalls made from synthetic fibers. These garments are highly prevalent in the activewear, athleisure, and performance wear segments due to the inherent properties of synthetic materials like stretch, moisture-wicking, and durability. Global trade is dominated by major sports apparel brands, fast fashion retailers, and large department stores in North America and Europe. Exporters are typically specialized textile manufacturers in countries known for advanced synthetic fiber production and garment assembly. Key aspects for trade include the specific synthetic blend (e.g., polyester, nylon, spandex), the knit structure, and performance features. These items are often subject to stringent quality and performance testing.

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).
