What HS 5801.31 covers

This HS code covers woven pile fabrics made from man-made fibers (like polyester, nylon, acrylic, rayon) that feature an uncut weft pile. These synthetic fabrics are highly valued in international trade for their durability, stain resistance, and often lower cost compared to natural fibers, while still offering a plush, soft texture. They are extensively used in upholstery, automotive interiors, and certain types of performance apparel. Major importers include large-scale furniture manufacturers, automotive suppliers, and contract textile buyers. Exporters are typically large textile conglomerates with advanced synthetic fiber production and weaving capabilities. Trade considerations include fiber type, pile density, fire retardancy, and resistance to wear and tear.

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).
