Last updated: September 2026 dataFiner-count uncombed cotton yarn in the 43–52 Nm range occupies a transitional grade between medium and fine spinning, used in lighter woven fabrics and certain knit constructions. India leads US imports under this heading, with Pakistan and Mexico also prominent suppliers. The 10-digit breakdown — 5205130000, 5205131000, and 5205132000 — reflects bleaching and mercerization distinctions that matter for downstream fabric finishing specifications.

Mercerized yarn has been treated with caustic soda under tension, improving luster, strength, and dye uptake. The US tariff schedule distinguishes mercerized from unbleached/unmercerized yarn at the 10-digit level within this subheading, so importers must confirm the finishing treatment with the mill to select the correct line and avoid post-entry corrections.
Both spinning methods are used, but open-end (rotor) spinning is more common at coarser counts, while ring spinning becomes more prevalent as counts increase toward 52 Nm. The spinning method affects yarn strength and surface character, which downstream weavers specify — and some 10-digit lines within related subheadings explicitly distinguish ring-spun from other constructions.
