Last updated: August 2026 dataSynthetic fiber knitted bottoms — polyester, nylon, and acrylic trousers, shorts, and overalls — are among the most commercially active lines in women's knitwear imports, driven by athleisure and performance-wear demand. The US schedule is highly granular, with separate lines for insulated overalls, wool-content thresholds (23% or more wool at 6104631510 and 6104631520), elastane content, playsuit components, and women's versus girls' sizing. Vietnam and Cambodia are the top two suppliers, with Jordan's notable presence reflecting qualifying industrial zone production that may carry preferential tariff treatment. Chinese-origin goods remain subject to Section 301 tariffs, a factor that has accelerated sourcing diversification toward Southeast Asian and Middle Eastern production hubs.

Jordan's presence reflects production in qualifying industrial zones (QIZs) established under a US-Jordan trade arrangement, which can provide preferential tariff treatment on eligible garments. Importers sourcing from Jordanian manufacturers should verify that specific goods meet the applicable rules of origin and QIZ content requirements to claim any preference.
The wool-content threshold takes precedence in the line structure: garments with 23% or more wool are directed to the wool-blend lines (6104631510 for trousers, 6104631520 for shorts) regardless of elastic yarn content. The elastic yarn split applies only within the sub-23%-wool lines. When in doubt, consult a licensed customs broker to confirm the correct 10-digit classification.
