HS code for Synthetic warp pile fabric: 5801.37
Fabrics, woven pile, of man-made fibres, warp pile fabrics, other than fabrics of heading no. 5802 or 5806.
Classification of synthetic warp pile fabric under HS 5801.37
Synthetic warp pile fabrics are classified under HS code 5801.37. These are woven fabrics where the pile (the raised surface) is created using an extra set of warp yarns. The classification falls under Chapter 58, which covers special woven fabrics and tufted textile fabrics. To qualify for 5801.37, the fabric must be made of man-made fibers (synthetic or artificial) and the pile must be specifically formed by the warp. This distinguishes it from weft pile fabrics like velveteen or corduroy. The classification process involves analyzing the weave structure under magnification to identify which yarn system creates the pile. This code excludes knitted pile fabrics (60.01) and tufted textile fabrics (58.02). The determination follows the Section XI notes regarding the definition of man-made fibers and the specific construction requirements of heading 58.01.

Codes often confused with 5801.37
Common mistake. The most common error is confusing 5801.37 with 5801.33, which is for weft pile fabrics. While they look similar, the technical construction of the pile determines the code. Another common mistake is using 60.01 for knitted pile fabrics; if the base is knitted rather than woven, 5801.37 is inapplicable. Terry toweling is also excluded and belongs in 58.02.

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).
