Fabrics, woven, dyed, containing less than 85% by weight of synthetic staple fibres (other than polyesters), mixed mainly or solely with cotton, exceeding 170g/m2.
Classification of heavyweight dyed synthetic cotton blend under HS 5514.29
The classification for heavyweight dyed synthetic cotton blends falls under HS code 5514.29. This code serves as a residual category for woven fabrics that contain less than 85% by weight of synthetic staple fibers other than polyester. These fibers are mixed mainly or solely with cotton and must have a weight exceeding 170g/m2. The fabric must also be dyed. The term "synthetic staple fibers other than polyester" typically refers to fibers such as acrylic, nylon (polyamide), or polypropylene staple fibers. Classification requires a detailed laboratory analysis of the fiber composition to confirm that polyester is not the dominant synthetic fiber. The weight threshold of 170g/m2 is a strict requirement; fabrics lighter than this are classified under heading 5513. The "dyed" status means the fabric has been colored in the piece, which distinguishes it from fabrics made of yarns of different colors or printed fabrics. This classification ensures that specialized synthetic blends are tracked accurately in international trade.

Codes often confused with 5514.29
Common mistake. The most common misclassification occurs with HS code 5514.22, which is reserved specifically for polyester staple fiber blends. If the synthetic fiber is polyester, 5514.29 cannot be used. It is also often confused with 5515, which covers other woven fabrics of synthetic staple fibers that are not mixed mainly or solely with cotton. Furthermore, if the fabric is printed rather than dyed, it would move to subheading 5514.49. Importers must verify the exact chemical nature of the synthetic fiber to avoid these errors.

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).
