HS Code 5515.99 – Fabrics, woven; of synthetic staple fibres n.e.c. in chapter 55, mixed mainly or solely with fibres n.e.c. in heading no. 5515
HS code 5515.99 is the 6-digit subheading for fabrics, woven, of synthetic staple fibres n.e.c. in chapter 55, mixed mainly or solely with fibres n.e.c. in heading no. 5515. It is used for polyester-cotton blend shirting, nylon-wool blend outerwear, polypropylene-linen blend upholstery, polyester-rayon blend suiting and synthetic staple-silk blend decorative fabric.
What HS 5515.99 covers
This broad category covers woven fabrics where synthetic staple fibers (excluding acrylic/modacrylic) are mixed mainly or solely with other fibers not specified elsewhere in heading 5515. This includes blends of polyester, nylon, or polypropylene staple fibers with natural fibers (e.g., cotton, linen, silk), wool, fine animal hair, or even other synthetic staple fibers. These fabrics are designed for a vast array of applications, leveraging the strengths of both synthetic and natural components – for instance, the breathability of cotton with the durability of polyester, or the warmth of wool with the easy care of nylon. Trade in these fabrics is driven by innovation in textile engineering, catering to diverse sectors from fashion and home textiles to specialized industrial uses. Importers range from large apparel brands to niche product manufacturers seeking specific functional or aesthetic qualities.

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).
