HS Code 5309.21 – Fabrics, woven; of flax, containing less than 85% flax, unbleached or bleached
HS code 5309.21 is the 6-digit subheading for fabrics, woven, of flax, containing less than 85% flax, unbleached or bleached. It is used for linen-cotton blend fabric, linen-rayon blend fabric, linen-viscose blend fabric, linen-polyester blend fabric and unbleached linen blend shirting.
What HS 5309.21 covers
This HS code pertains to woven fabrics primarily made of flax, but with less than 85% flax content, meaning they are blended with other fibers, and are in an unbleached or bleached state. These fabrics offer the natural aesthetic, breathability, and strength of linen, combined with enhanced properties (e.g., wrinkle resistance, improved drape, cost-effectiveness) provided by the blend, often with cotton, rayon, or polyester. They are widely traded for apparel, home textiles like tablecloths, curtains, and bedding, and light upholstery. Importers include garment manufacturers, home textile producers, and fabric distributors seeking natural-look blended fabrics with improved performance. Exporters are typically textile mills in flax-producing regions or countries with strong blending and weaving capabilities. Key considerations for trade involve the specific blend composition, the degree of bleaching, and the fabric's intended end-use, which dictates desired texture, finish, and care properties.

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).
