HS Code 6006.31 – Fabrics; knitted or crocheted fabrics, other than those of headings 60.01 to 60.04, of synthetic fibres, unbleached or bleached
HS code 6006.31 is the 6-digit subheading for fabrics, knitted or crocheted fabrics, other than those of headings 60.01 to 60.04, of synthetic fibres, unbleached or bleached. It is used for unbleached polyester jersey, bleached nylon interlock, raw spandex blend rib knit, bleached acrylic fleece and grey polyester single jersey.
What HS 6006.31 covers
HS 600631 covers unbleached or bleached knitted or crocheted fabrics made from synthetic fibres, excluding those of headings 60.01 to 60.04. These versatile fabrics are foundational for a wide range of applications, from activewear and sportswear to industrial textiles and linings. Major importers include sportswear brands, activewear manufacturers, and producers of technical textiles who value the inherent properties of synthetics like durability, moisture-wicking, and stretch. Exporters are typically large chemical and textile companies in countries with strong petrochemical industries and advanced synthetic fiber production. Key aspects of trade involve the specific type of synthetic fiber (e.g., polyester, nylon, spandex), fabric construction, weight, and technical specifications for various end-uses, often traded as bulk commodities.

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).
