Last updated: July 2026 dataRetail-packaged silk yarn and yarn spun from silk waste occupy a specialized niche in the luxury textile supply chain, serving hand-weavers, embroiderers, and high-end apparel producers. The US schedule breaks this heading into three 10-digit lines: 5006000000 (general), 5006001000 (spun from silk waste, at least 85% silk or silk waste), and 5006009000 (other, including silkworm gut). India leads US imports under this heading, followed by Japan, reflecting both volume production and artisan-grade specialty output. Because these yarns are sold in retail form, classification hinges on packaging and presentation rather than fiber composition alone.

The key split is fiber-content threshold and end product: 5006001000 covers yarn spun from silk waste containing at least 85% silk or silk waste, while 5006009000 captures all other silk yarn, yarn spun from silk waste put up for retail sale, and silkworm gut. Correct classification requires verifying both the fiber-content percentage and whether the product is genuinely put up for retail sale.
Importers should be prepared to show that the yarn is wound on spools, cards, or similar retail packaging in quantities suitable for individual consumer purchase. Bulk cones or industrial-scale packages are generally not considered 'put up for retail sale' and would classify elsewhere in Chapter 50. A licensed customs broker can help confirm packaging meets the heading's retail-sale criterion.
