Last updated: July 2026 dataElastic thread and cord made from vulcanized rubber—whether or not textile-covered—classifies under a single line, 4007000000, and is a critical input for apparel waistbands, medical compression garments, and industrial bungee applications. Thailand and Malaysia together dominate US supply, reflecting their deep integration in natural-rubber processing and elastic-thread manufacturing; China is also a notable source, and Section 301 tariff exposure should be confirmed for Chinese-origin shipments. Buyers should note that textile-covered rubber thread may alternatively classify under Chapter 56 if the textile component is considered the essential character.

Rubber thread of heading 4007 is vulcanized rubber in thread or cord form, with or without textile covering. Once the thread is used as the core of a textile yarn—where the textile wrapping gives the product its essential character—it may shift to Chapter 56 (man-made filaments or wadding). The classification turns on whether rubber or textile predominates; a binding ruling from CBP is advisable for borderline products.
Key specifications include elongation-at-break percentage, recovery rate, denier or gauge, and heat/chemical resistance. Natural-rubber thread from Thailand and Malaysia typically offers superior elasticity and recovery, while synthetic-rubber thread may be preferred for ozone or UV resistance in outdoor applications. These performance differences often determine whether buyers source from Southeast Asia or diversify to other origins.
