HS code for Synthetic pile fabric: 5801.31
Fabrics, woven pile, of man-made fibres, uncut weft pile fabrics, other than fabrics of heading no. 5802 or 5806.
Classification of synthetic pile fabric under HS 5801.31
Synthetic pile fabrics are classified under HS code 5801.31 based on their textile construction and fiber origin. Heading 5801 covers woven pile fabrics and chenille fabrics. The classification process first identifies the fiber type; since these are made of man-made (synthetic) fibers, they fall into the 5801.3x series. The specific subheading 5801.31 is designated for "uncut weft pile fabrics." In textile terms, a pile fabric is one where an additional set of yarns (the pile) is woven into a base fabric to create a raised surface. In weft pile fabrics, the pile is formed by the weft (horizontal) yarns. The "uncut" designation means the loops created during the weaving process have not been sheared or cut to create a velvet-like surface. This distinction is vital for customs purposes, as the manufacturing complexity and the resulting texture of uncut pile differ significantly from cut pile (5801.32). These fabrics are often used in upholstery, specialized apparel, and industrial applications where a durable, textured surface is required. The classification excludes knitted or crocheted pile fabrics, which are found in Chapter 60, and narrow woven fabrics of heading 5806.

Codes often confused with 5801.31
Common mistake. The most common misclassification is with 5801.32, which covers cut weft pile fabrics (like standard velvet). It is also confused with 5801.21 if the material is cotton instead of synthetic. Furthermore, knitted pile fabrics are often incorrectly placed here but belong in 6001. If the fabric is less than 30 cm wide, it may fall under 5806 as a narrow woven fabric.

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).
