HS Code for Uncut weft pile synthetic fabric

Uncut weft pile synthetic fabric is classified under HS code 5801.31. This classification is dictated by the material composition—specifically man-made fibers such as polyester, nylon, or acrylic—and the specific construction of the textile. Under the Harmonized System, woven pile fabrics are categorized by the fiber type and the state of the pile. For 5801.31, the pile must be created using supplementary weft yarns that are floated over the surface and left as loops. This 'uncut' state is the defining characteristic that separates it from cut pile fabrics like synthetic velvet. The use of synthetic filaments or staple fibers provides different durability and moisture-wicking properties compared to natural fibers, which is why the HS system separates man-made fibers (5801.31) from cotton (5801.21) or wool (5801.10). Proper classification requires a laboratory analysis of the fiber content to ensure it meets the 'man-made' criteria of Chapter 54 or 55.

Common Misclassification

A common error is classifying these goods under HS code 6001, which covers knitted pile fabrics. While they may look similar, 5801.31 is strictly for woven fabrics. Another frequent misclassification occurs with HS code 5801.32, which is for cut weft pile synthetic fabrics. If the loops have been sheared or cut to create a soft pile, 5801.31 is no longer applicable. Importers also confuse this with 5801.33, which covers synthetic warp pile fabrics.

FAQ

What is the HS code for uncut weft pile synthetic fabric?

The correct HS code for this material is 5801.31, provided it is woven and made of man-made fibers.

Can this code be used for microfiber fabrics?

Only if the microfiber is woven into an uncut weft pile structure. Most microfiber cloths are knitted and would fall under Chapter 60 instead.
