HS code for Synthetic knit fabric: 6006.31
Fabrics, knitted or crocheted fabrics, other than those of headings 60.01 to 60.04, of synthetic fibres, unbleached or bleached.
Classification of synthetic knit fabric under HS 6006.31
Synthetic knit fabric classified under HS code 6006.31 refers to knitted or crocheted fabrics made of synthetic fibers that are either unbleached or bleached. This code is part of Chapter 60, which encompasses all knitted or crocheted fabrics. The classification 6006.31 is a specific subset for "other" fabrics, meaning it excludes pile fabrics (60.01), "long pile" fabrics, and fabrics containing 5% or more by weight of elastomeric yarn or rubber thread (60.04). The "unbleached or bleached" designation is a primary differentiator; if the fabric is dyed, printed, or made of yarns of different colors, it would fall under 6006.32, 6006.34, or 6006.33 respectively. The classification requires a technical analysis of the knitting structure (weft vs. warp) and the chemical nature of the fibers. Synthetic fibers include polyester, polyamide, and acrylic. This fabric is commonly used as a base material for further garment manufacturing or industrial applications where the color has not yet been finalized.

Codes often confused with 6006.31
Common mistake. A common error is classifying these fabrics under 6001.92 if they have a raised surface, as those are considered pile fabrics. Another frequent mistake is using 6004.10 for fabrics that contain even a small amount of spandex; if the elastomeric content is 5% or more, heading 6004 takes precedence over 6006. Furthermore, if the fabric is woven rather than knitted, it must be classified in Chapter 54 (for filament) or Chapter 55 (for staple fibers), specifically headings like 5407 or 5512.
Top exporters and importers of HS 600631 (the code used for synthetic knit fabric), 2025
In 2025, the largest exporter of HS 600631 (the code used for synthetic knit fabric) in UN Comtrade data was China, with 43% of world exports; the largest importer in UN Comtrade data was Egypt, with 9.7% 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 23% of its imports here ($20M, 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).
