HS Code 5206.21 – Cotton yarn; (not sewing thread), single, of combed fibres, less than 85% by weight of cotton, measuring 714.29 decitex or more, (not exceeding 14 metric number), not for retail sale
HS code 5206.21 is the 6-digit subheading for cotton yarn, (not sewing thread), single, of combed fibres, less than 85% by weight of cotton, measuring 714.29 decitex or more, (not exceeding 14 metric number), not for retail sale. It is used for coarse combed cotton blend yarn, heavy duty blended yarn for denim, combed yarn for industrial canvas, blended yarn for upholstery fabrics and yarn for workwear textiles.
What HS 5206.21 covers
This HS code pertains to coarse, single, combed cotton yarn, not for retail, with a cotton content below 85% by weight, and a fineness of 714.29 decitex or more. The "combed" characteristic indicates a higher quality yarn, as the combing process removes shorter fibers and impurities, resulting in a smoother, stronger, and more uniform yarn compared to uncombed varieties. Despite being coarse, the combed nature makes it suitable for applications where durability and a cleaner appearance are desired, even in blended fabrics. Importers are typically manufacturers of heavy-duty textiles, industrial fabrics, denim, and robust home furnishings. Countries with significant textile manufacturing capabilities, such as China, India, Pakistan, and Turkey, are key players in both the import and export of these yarns. Trade in this category is influenced by demand for durable blended fabrics, the cost of raw cotton, and the efficiency of spinning mills. Buyers prioritize consistent strength, low hairiness, and uniform blend ratios for their industrial applications.

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).
