Cotton knitted trousers and shorts for women and girls represent one of the most heavily subdivided categories in Chapter 61, with the US schedule distinguishing insulated versus non-insulated overalls, elastane yarn content (≥5% elastic yarn lines), playsuit components, and women's versus girls' sizing across more than a dozen 10-digit lines. The elastane-content split — separating trousers with 5% or more elastic yarn from those without — reflects the commercial importance of stretch-cotton fabrications in activewear and athleisure. Vietnam leads US supply, followed by Indonesia, Cambodia, China, and Bangladesh, giving importers a broad Southeast Asian sourcing base. Section 301 tariffs apply to Chinese-origin goods, and the playsuit-component lines (e.g., 6104622016, 6104622021) require importers to confirm whether girls' shorts are imported as part of a coordinated set.
