Classification of cotton warp knit fabric under HS 6005.21
Cotton warp knit fabric is classified under HS code 600521. This classification is based on the specific knitting construction where loops are formed in a vertical or diagonal direction along the length of the fabric. Chapter 60 of the Harmonized System is dedicated to knitted or crocheted fabrics. Heading 6005 specifically covers warp knit fabrics, including those made on galloon knitting machines, provided they do not fall under the specialized categories of pile fabrics (6001) or fabrics containing 5% or more of elastomeric yarn (6002 to 6004). The subheading 600521 is designated for cotton warp knit fabrics that are in an unbleached or bleached state. The technical distinction between warp knitting and weft knitting is the primary driver for this classification, as warp knit fabrics offer superior dimensional stability and are less prone to laddering compared to weft-knitted counterparts.

Codes often confused with 6005.21
Common mistake. This code is often confused with HS code 600621, which covers other knitted or crocheted fabrics of cotton (typically weft-knitted). It is also sometimes misclassified under 6001 if the fabric has a pile surface, or under 6002-6004 if the fabric contains significant amounts of elastomeric yarn or is of a specific narrow width. Accurate identification requires a physical inspection of the loop structure to confirm it is indeed warp-knitted.

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).
