HS Code 5515.21 – Fabrics, woven; of acrylic or modacrylic staple fibres n.e.c. in chapter 55, mixed mainly or solely with man-made filaments
HS code 5515.21 is the 6-digit subheading for fabrics, woven, of acrylic or modacrylic staple fibres n.e.c. in chapter 55, mixed mainly or solely with man-made filaments. It is used for acrylic-filament blend suiting fabric, modacrylic-filament upholstery fabric, faux fur fabric (acrylic/filament blend), performance sportswear fabric and decorative curtain fabric.
What HS 5515.21 covers
This HS code encompasses woven fabrics crafted from acrylic or modacrylic staple fibres, which are predominantly blended with man-made filaments. These fabrics are engineered to combine the warmth, softness, and bulk of acrylics with the strength, durability, and often lustrous appearance of continuous man-made filaments like polyester or nylon. They are widely utilized in the textile industry for various applications, including apparel (e.g., suiting, outerwear, faux fur), home furnishings (upholstery, blankets, decorative fabrics), and certain industrial textiles where resilience and aesthetic appeal are crucial. Major importers are typically garment manufacturers, fashion brands, and fabric distributors in developed economies, while exporters are large-scale textile mills, primarily located in Asia. Key considerations for trade include the specific blend ratio, the denier of the filaments, and the fabric's finish, all of which influence its performance and market value.

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).
