Last updated: August 2026 dataSingle yarns composed of at least 85% nylon or other polyamide staple fibers, sold in bulk rather than retail form, are a key intermediate for industrial fabric weaving and knitting operations. The US tariff line 5509110000 covers this product, and the 85% threshold is a hard classification boundary — blended yarns falling below that level shift to different subheadings. Nylon staple yarn in this category is used in hosiery, technical textiles, and certain carpet constructions where polyamide's abrasion resistance is valued.

Yarns falling below the 85% polyamide threshold are classified based on their predominant fiber content under the appropriate 'mixed fiber' or 'other' subheadings within Chapter 55. The 85% rule is a bright-line test: importers must obtain fiber composition test reports from the manufacturer to confirm the threshold is met, as misclassification can result in duty underpayment or overpayment.
Yarn 'not for retail sale' is typically shipped on large industrial cones, cheeses, or in bulk form intended for further manufacturing. Yarn put up for retail sale — on small spools, in skeins with consumer labeling, or in quantities typical of craft or household use — would be classified under a different heading. The determining factor is the presentation and intended end-use channel, not the fiber content.
