Product classification
HS code for Synthetic filament 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 filament fabric under HS 5515.91
Synthetic filament fabric is classified under HS code 5515.91 when it consists of woven fabrics made of synthetic staple fibers mixed mainly or solely with man-made filaments. This classification is nuanced because it sits at the intersection of Chapter 54 (filaments) and Chapter 55 (staple fibers). According to the Section XI notes, the classification is determined by the weight of the constituent fibers. For 5515.91, the fabric must contain a significant portion of synthetic staple fibers (fibers of finite length) but be reinforced or blended with continuous man-made filaments. These fabrics are often used in the production of apparel, such as suits or trousers, where the staple fibers provide a natural feel while the filaments add strength and durability. The weaving pattern (plain, twill, or satin) does not change this heading, provided the fiber blend ratio meets the criteria for 'mixed mainly with man-made filaments.'

Codes often confused with 5515.91
Common mistake. This product is often confused with HS code 5407, which covers woven fabrics of synthetic filament yarn. If the fabric is 100% filament, it belongs in 5407. Conversely, if the fabric is 100% staple fiber or contains more than 85% staple fiber without being specifically 'mixed' with filaments in the manner described by 5515, it may fall under 5512. Importers must have a precise laboratory analysis of the fiber weight percentages to distinguish between these codes accurately.
Top exporters and importers of HS 551591 (the code used for synthetic filament fabric), 2025
In 2025, the largest exporter of HS 551591 (the code used for synthetic filament 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.
Figures cover everything classified under HS 551591, not only synthetic filament 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).

Questions about synthetic filament fabric
What is the HS code for Synthetic filament fabric?
The HS code for Synthetic filament fabric is 551591 (Fabrics, woven; of synthetic staple fibres n.e.c. in chapter 55, mixed mainly or solely with man-made filaments). The HS code for woven fabrics of synthetic staple fibers mixed with man-made filaments is 5515.91.
How do I classify Synthetic filament fabric for customs?
Synthetic filament fabric is classified under HS code 551591 — Fabrics, woven; of synthetic staple fibres n.e.c. in chapter 55, mixed mainly or solely with man-made filaments. This is a 6-digit subheading level code.
How is 'mixed mainly' defined for this code?
It generally refers to the weight percentage where the staple fibers are the predominant textile material by weight, but the filament component is a secondary essential element of the blend.
Which countries are the top exporters of synthetic filament fabric (HS 551591)?
In 2025, the top exporters of HS 551591 (the code used for synthetic filament fabric) in UN Comtrade data were the United States ($17M, 26% of world exports), France ($8.3M) and India ($6.1M). World exports came to about $65M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of synthetic filament fabric (HS 551591)?
In 2025, the top importers of HS 551591 (the code used for synthetic filament fabric) in UN Comtrade data were Tunisia (about $9.8M, 13% of world imports), Canada ($7.0M) and Vietnam (about $6.9M). World imports came to about $77M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). 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.
