Last updated: August 2026 dataKnitted dresses constructed primarily of synthetic fibers — polyester, nylon, and acrylic blends being the most common — are subdivided at the 10-digit level by gender (women's vs. girls') and by wool content, with lines 6104431010 and 6104431020 reserved for garments containing 23% or more wool. Vietnam leads US import supply for this heading, followed by China and Indonesia, reflecting the concentration of synthetic knit apparel manufacturing in Southeast Asia.

If the dress is made of synthetic fibers but contains 23% or more by weight of wool or fine animal hair, it falls under the wool-blend lines (6104431010 for women's, 6104431020 for girls'). Dresses with less than 23% wool are classified under the 'other synthetic fibers' lines. Accurate fiber-content testing and mill certifications are essential to support the correct line selection.
Yes. Imports of knit synthetic dresses from China have been subject to Section 301 tariffs. Importers sourcing from Vietnam or Indonesia — the other leading suppliers — should still verify current tariff treatment, as trade remedy exposure can shift. Consulting a licensed customs broker before shipment is advisable.
