What HS 5206.31 covers

This HS code covers very coarse, multiple or cabled cotton yarn, made from uncombed fibers, containing less than 85% by weight of cotton. With a count of 714.29 decitex or more, these yarns are not for retail sale and are primarily used for heavy-duty industrial textiles, robust workwear, and durable home furnishings where strength, bulk, and cost-effectiveness are paramount. The 'less than 85% cotton' indicates a blend, often with synthetic fibers, to enhance durability, abrasion resistance, or reduce material costs. Importers are manufacturers of industrial fabrics, ropes, heavy-duty apparel, and technical textiles. Exporters are usually large-scale spinning mills in cotton-producing regions with the capacity for producing coarse, blended yarns in bulk.

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).
