Yarn-dyed construction — where individual yarns are colored before knitting — is the technical hallmark that separates heading 600523 from piece-dyed (600522) and printed (600524) warp-knit cotton fabrics, and that upstream processing step is what customs authorities examine when auditing classification. Italy is the leading supplier to the US, reflecting that country's strength in specialty yarn-dyed knit fabrics for fashion and home textiles; Mexico is also a notable source. All US imports are captured under tariff line 6005230000, and goods from Mexico may benefit from USMCA preferential treatment if applicable rules of origin are satisfied.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Importers typically rely on mill certificates or production records confirming that yarns were dyed prior to knitting, along with fabric swatches showing the color pattern is integral to the structure (visible on both faces) rather than applied to the surface. A cross-section analysis or unraveling test can also demonstrate that individual yarns carry distinct colors throughout their length.
Potentially yes, but only if the goods satisfy the applicable textile rule of origin under USMCA — typically a 'yarn-forward' requirement meaning the yarn must be formed in a USMCA country. Importers should verify the full production chain with their supplier and file a proper USMCA claim with supporting documentation; a licensed customs broker can confirm eligibility for a specific shipment.
