HS code for Bleached 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 bleached synthetic knit fabric under HS 6006.31
Bleached synthetic knit fabric is classified under HS code 6006.31. Chapter 60 of the Harmonized System is dedicated to knitted or crocheted fabrics. Heading 6006 covers 'other' knitted or crocheted fabrics that are not pile fabrics (6001) or those containing a high percentage of elastomeric yarn (6002-6004). Subheading 6006.31 is specific to fabrics made of synthetic fibers that are unbleached or bleached. The classification depends on the construction method (knitting) and the chemical nature of the fibers (synthetic, such as polyester, nylon, or acrylic). Bleaching is a critical distinction here, as it indicates the fabric has undergone a chemical whitening process but has not yet been dyed, printed, or made from yarns of different colors. This fabric is widely used in the garment industry as a base material for t-shirts, sportswear, and linings where a clean, white finish is required before further processing or for final use.

Codes often confused with 6006.31
Common mistake. This code is often confused with 6006.32, which is for dyed synthetic knit fabrics. It is also frequently misclassified under 6001 if the fabric has a raised nap or pile surface. If the fabric contains 5% or more by weight of elastomeric yarn and measures more than 30 cm in width, it should be classified under 6004.10. Importers must also ensure they do not use Chapter 54 or 55, which are strictly for woven fabrics.

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).
