Classification of dyed polyester tricot under HS 6005.37
Dyed polyester tricot is classified under HS code 6005.37 because it meets the specific criteria for warp-knit fabrics made of synthetic fibers that have undergone a dyeing process. The Harmonized System (HS) distinguishes between different knitting methods; tricot is a form of warp knitting where the yarn loops move lengthwise through the fabric. Heading 60.05 specifically covers warp-knit fabrics (including those made on galloon knitting machines) other than those of headings 60.01 to 60.04. Since polyester is a synthetic polymer, it falls under the synthetic fiber category. The 'dyed' designation applies to fabrics that have been colored in a single uniform color after the knitting process, distinguishing them from unbleached, bleached, or printed fabrics. To qualify for this code, the fabric must not contain more than 5% by weight of elastomeric yarn or rubber thread, as those would be classified under heading 60.04.

Codes often confused with 6005.37
Common mistake. This product is frequently misclassified under HS code 6001.92, which covers pile fabrics of man-made fibers. While some tricot can have a brushed surface, it only moves to 60.01 if it has a distinct pile or loops. Another common error is using HS code 5407.52, which is for woven fabrics of synthetic filament yarn; however, tricot is knitted, not woven. Additionally, if the fabric contains more than 5% elastomeric yarn, it must be classified under 6004.10 instead of 6005.37.

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).
