U.S. imports of multiple or cabled synthetic staple fiber yarn (other than acrylic/modacrylic), ≥85% synthetic staple fibers, not for retail sale (HS 550942) totaled $406K in April 2026, traded with 10 countries.
Last updated: April 2026 dataPlied or cabled constructions of non-acrylic, non-polyester synthetic staple fibers at 85% or more by weight — including polypropylene and PVA — are classified here when sold in bulk industrial form. Three US tariff lines apply: 5509420000 (general), 5509420010 (PVA), and 5509420090 (other). Italy leads US import supply for this heading, with China and Germany also among the top sources, pointing to technically sophisticated spinning operations in Europe and Asia. As with the single-yarn counterpart, the PVA subdivision (5509420010) targets water-soluble and construction-grade fiber applications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Importers should provide a fiber composition certificate from the manufacturer confirming that the dominant fiber is a synthetic staple fiber other than polyester, acrylic, or modacrylic, and that it constitutes 85% or more by weight. If polyester is the dominant fiber at any level, the yarn would instead fall under the 550941/550942 polyester-dominant subheadings or the blended polyester headings (550951–550959). A binding ruling from CBP can provide certainty for recurring shipments.
The HTS distinguishes single yarn (550941) from multiple or cabled yarn (550942), and the two lines can carry different duty rates. The physical construction — whether strands are twisted together — is therefore a classification-relevant fact, not merely a commercial description. Importers should confirm the yarn's construction with the mill and ensure it is accurately declared on the entry.
