Kevlar 49 Aramids High Tenacity Yarn from China
Kevlar 49 is a high tenacity aramid multifilament yarn with twist less than 5 turns per meter, exceeding 920 decitex, used in aerospace composites and ballistic protection. It falls under HTS 5402.11.30.50 as synthetic aramid yarn of nylon or polyamides, single yarn configuration, not put up for retail sale. This classification reflects its untwisted or low-twist structure and high-strength properties.

Import Tips
• Verify yarn tenacity exceeds high-tenacity thresholds and twist <5 tpm via lab testing for Chapter 54 compliance
• Provide manufacturer's specs confirming aramid composition and decitex >920 to avoid reclassification as sewing thread
• Ensure not packaged for retail; bulk spools only, as retail puts up shifts to Chapter 55
