HS Code 6103.23 – Ensembles; men's or boys', of synthetic fibres, knitted or crocheted
HS code 6103.23 is the 6-digit subheading for ensembles, men's or boys', of synthetic fibres, knitted or crocheted. It is used for men's polyester knit tracksuit, boys' synthetic fiber athletic ensemble, men's nylon blend activewear set, boys' spandex blend performance ensemble and men's knitted synthetic loungewear.
What HS 6103.23 covers
This HS code pertains to knitted or crocheted ensembles for men and boys made from synthetic fibers. These materials, such as polyester, nylon, and spandex, are highly valued for their durability, moisture-wicking properties, stretch, and often lower cost compared to natural fibers. Consequently, these ensembles are extremely popular in sportswear, activewear, and performance apparel markets, as well as for casual and loungewear where easy care is desired. The international trade is dominated by large sportswear brands, fast fashion retailers, and specialized textile manufacturers. Exporters are often found in regions with advanced synthetic fiber production and garment manufacturing infrastructure, while importers are global retailers catering to active lifestyles and budget-conscious consumers. Key considerations include the specific synthetic blend, the knit structure (e.g., double knit, mesh), and functional features like breathability or quick-drying capabilities.

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).
