HS Code 6005.21 – Fabrics; warp knit (including those made on galloon knitting machines), other than those of headings 60.01 to 60.04, of cotton, unbleached or bleached
HS code 6005.21 is the 6-digit subheading for fabrics, warp knit (including those made on galloon knitting machines), other than those of headings 60.01 to 60.04, of cotton, unbleached or bleached. It is used for unbleached cotton tricot fabric, bleached cotton mesh fabric, raw cotton lace (warp knit), unfinished cotton net fabric and bleached cotton lining fabric.
What HS 6005.21 covers
This code specifically targets warp-knitted cotton fabrics, including those from galloon knitting machines, that are unbleached or bleached, and exceed 30 cm in width. Warp knitting creates fabrics with excellent dimensional stability, run resistance, and often a finer gauge compared to weft knits, making them suitable for lingerie, technical textiles, and certain apparel linings. The "unbleached or bleached" state indicates they are raw materials for further processing like dyeing or printing. Major importers are textile finishing plants and garment manufacturers in Asia, Europe, and North America, who then add value through subsequent treatments. Exporters are typically countries with strong cotton production and advanced warp knitting capabilities, such as China, India, and Pakistan. Understanding the warp knit structure is crucial, as it offers different properties than weft knits.

In 2025, the largest exporter of HS code 600521 in UN Comtrade data was Switzerland, with 26% of world exports; the largest importer in UN Comtrade data was Finland, with 26% of world imports. Uzbekistan 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 43% of its exports here ($5.7M, CEPII BACI), so it may rank higher. Russia 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 94% of its imports here ($4.5M, CEPII BACI), so it may also belong among the top importers.

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).
