Last updated: September 2026 dataKnitted and crocheted synthetic fabrics woven from yarns of different colors — producing stripes, patterns, or jacquard effects directly in the knitting process rather than through post-construction dyeing or printing — serve niche apparel and home-textile applications where color integration is a design requirement. The US schedule distinguishes nylon (6006330020) and polyester (6006330040) double-knit constructions from other double-knit (6006330060) and other knit configurations (6006330080). Notably, Mexico and Canada lead US supply for this subheading, reflecting integrated North American textile production networks, with Turkey and China also contributing. USMCA origin rules can affect duty treatment for goods sourced from Mexico or Canada.

Classification as 'yarns of different colors' requires that the color variation be inherent in the yarn before knitting — visible as distinct colored yarns in the fabric structure — rather than applied to the finished fabric surface. Inspectors may examine the fabric's reverse side or cross-section; if color penetration is uniform throughout individual yarns, the 'yarn dyed' classification is supported. Importers should retain mill documentation confirming the yarn-dyeing process.
Goods originating in Mexico may qualify for preferential duty treatment under USMCA, but eligibility depends on meeting the applicable tariff shift or fiber-forward rules of origin. Importers should work with a licensed customs broker to verify that the fabric satisfies USMCA's textile-specific rules before claiming preference.
