What HS 6005.37 covers
This HS code covers warp knit fabrics made from synthetic fibers that have been uniformly dyed to a solid color. These fabrics are ready for cut-and-sew operations, having already undergone the coloring process, which makes them highly desirable for manufacturers seeking finished materials. They are extensively used in activewear, intimate apparel, swimwear, and certain home textiles where consistent, solid colors are required. Importers are typically garment manufacturers, upholstery producers, and retailers sourcing finished fabric for their product lines. Exporters are textile mills with integrated dyeing capabilities or specialized dyeing houses. Key considerations for trade include color fastness, shade consistency across batches, and compliance with environmental dyeing standards.

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).
