Classification of heavyweight dyed poly-cotton plain weave under HS 5514.21
The classification of heavyweight dyed poly-cotton plain weave fabric under HS code 5514.21 is determined by the intersection of material composition, weight, and construction. This code is specific to woven fabrics containing less than 85% polyester staple fibers by weight, blended primarily with cotton. The fabric must weigh more than 170g/m2 and be dyed. The defining characteristic for this specific subheading is the plain weave structure, which is the most basic textile weave where the warp and weft threads cross each other alternately. This construction provides a durable, uniform surface suitable for heavy-duty applications. According to the Section XI notes of the HS nomenclature, the distinction between staple fibers and filaments is crucial; staple fibers are short lengths that must be spun into yarn. If the fabric weighed 170g/m2 or less, it would be classified under heading 5513. The classification ensures that heavy-duty utility fabrics are separated from lighter dress or shirt fabrics, reflecting their different economic values and industrial uses.

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).
