Product classification
HS code for Lightweight dyed synthetic blend: 5513.29
Fabrics, woven, dyed, containing less than 85% by weight of synthetic staple fibres (other than polyesters), mixed mainly or solely with cotton, not exceeding 170g/m2.
Classification of lightweight dyed synthetic blend under HS 5513.29
HS code 551329 applies to woven fabrics containing less than 85% synthetic staple fibers other than polyester, mixed mainly with cotton. These fabrics are dyed and weigh 170g/m2 or less. This code captures blends involving fibers like acrylic, modacrylic, or nylon staple fibers. The classification depends on the staple fiber being the main component by weight relative to the cotton, but not exceeding the 85% threshold. If the synthetic content were 85% or more, the fabric would move to heading 5512. The 'dyed' requirement means the fabric has undergone a coloring process after weaving. The 'other' designation for synthetic staple fibers excludes polyester, which has its own specific subheadings (like 5513.23). This category is essential for specialized blends where specific synthetic properties, such as the moisture-wicking of nylon or the wool-like feel of acrylic, are desired in a lightweight, cotton-rich blend. The weight limit of 170g/m2 is a critical metric for Chapter 55. The weave must be analyzed to ensure it does not fall under specific plain weave categories. Because these are staple fibers, the yarns have a characteristic fuzziness or texture compared to the smooth surface of filament yarns. Classification requires a detailed fiber breakdown to ensure the 'other' synthetic fiber is indeed the majority component over the cotton.

Codes often confused with 5513.29
Common mistake. The most common misclassification is using 5513.23, which is specifically for polyester blends. Another error is confusing these with filament blends in 5407; 5513.29 is strictly for staple fibers. If the cotton content is higher than the synthetic content by weight, the fabric should be classified under 5210.39. Additionally, if the fabric is unbleached or bleached rather than dyed, it would fall under 5513.19. Weight is also a factor; if the fabric exceeds 170g/m2, it moves to 5514.90.

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).
