Last updated: April 2026 dataMedium-count single uncombed blended cotton yarn in the 14–43 NM range serves a broad range of fabric applications, from denim and workwear to mid-weight wovens and knits. Mexico and Pakistan are the top US suppliers, with El Salvador also a notable source — a regional supply pattern shaped by proximity to US textile mills and established trade relationships. The heading resolves to a single US tariff line (5206120000), so classification depends entirely on confirming fiber content below 85% cotton by weight and a metric number within the 14–43 NM window. Importers sourcing from Mexico or Canada may benefit from USMCA tariff treatment, subject to applicable rules of origin.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yarn originating in Mexico may qualify for preferential USMCA tariff treatment, provided it meets the applicable rules of origin — typically a fiber-forward or yarn-forward requirement under the textile chapter. Importers should verify origin qualification with a licensed customs broker before claiming preference.
The dividing line is the metric number per single yarn: 520612 covers yarn over 14 NM up to 43 NM, while 520613 covers yarn over 43 NM up to 52 NM. A yarn testing at exactly 43 NM falls in 520612; one testing above 43 NM moves to 520613. Accurate NM measurement from the mill is essential.
