Last updated: August 2026 dataSynthetic fiber knitted trousers — predominantly polyester-based activewear and performance legwear — represent a high-volume segment of men's and boys' apparel imports. Vietnam leads supply under this heading, with Jordan and Cambodia also significant; Jordan's presence reflects qualifying industrial zone production that has historically benefited from favorable trade arrangements. The US schedule is among the most granular in Chapter 61, with thirteen 10-digit lines separating wool-blend thresholds, insulation status, men's versus boys' cuts, and overalls subcategories.

Jordan's apparel exports to the US benefit from the US-Jordan Free Trade Agreement, which provides duty-free access for qualifying goods. Additionally, Qualifying Industrial Zones (QIZs) established under a separate arrangement have historically allowed Jordanian manufacturers to export duty-free when meeting specific Israeli-input content requirements. Importers sourcing from Jordan should verify current FTA and QIZ eligibility and maintain the required certificates of origin.
If synthetic fiber (polyester) predominates by weight, the garment falls under heading 610343. Because the wool content reaches 23% or more, it classifies under 6103431010 (trousers and breeches) or 6103431020 (shorts) rather than the 'other synthetic fibers' lines. Accurate fiber-content documentation is essential, as the 23% threshold is a hard line that determines the applicable tariff line.
