These fabrics are highly regarded for their resilience, luxurious feel, and often superior drape compared to weft pile synthetics. They are traded globally for high-end upholstery, automotive interiors, and specialized apparel where durability, aesthetic appeal, and performance are paramount. Importers include luxury furniture brands, automotive manufacturers, and designers seeking advanced textile solutions. Exporters are often technologically advanced textile mills. Key trade considerations include the specific synthetic fiber used, pile density, abrasion resistance, and compliance with industry-specific performance standards.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
