Product classification
HS code for Synthetic blend fabric: 5515.91
Fabrics, woven, of synthetic staple fibres n.e.c. in chapter 55, mixed mainly or solely with man-made filaments.
Classification of synthetic blend fabric under HS 5515.91
Synthetic blend fabric under HS code 551591 is classified within Chapter 55, which encompasses man-made staple fibers. This specific code is used for woven fabrics of synthetic staple fibers that are mixed mainly or solely with man-made filaments. The classification depends on the weight of the synthetic staple fibers (such as polyester or nylon staple) being the predominant textile material by weight. Because the fabric is a blend of staple fibers and continuous filaments, it falls under the "other woven fabrics" category of heading 5515. This classification is essential for distinguishing between fabrics made entirely of filaments (Chapter 54) and those made of staple fibers mixed with other materials like cotton or wool, which have their own specific subheadings within Chapter 55.

Codes often confused with 5515.91
Common mistake. This code is often confused with HS code 5407, which covers woven fabrics of synthetic filament yarn. The distinction lies in the presence of staple fibers; if the fabric contains staple fibers as the primary component, it must stay in Chapter 55. It is also confused with HS code 551511, which is specifically for polyester staple fibers mixed with viscose rayon. Code 551591 is a residual category for blends with man-made filaments that are not more specifically described elsewhere in the heading.
Top exporters and importers of HS 551591 (the code used for synthetic blend fabric), 2025
In 2025, the largest exporter of HS 551591 (the code used for synthetic blend fabric) in UN Comtrade data was the United States, with 26% of world exports; the largest importer in UN Comtrade data was Tunisia, with about 13% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 2.2% of its imports here ($161K, CEPII BACI), so it may rank higher.

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).
