6815.11.00.00/Toray T700S Carbon Fiber Tow/Mexico

Toray T700S Carbon Fiber Tow from Mexico

Toray T700S is a high-strength carbon fiber tow consisting of continuous filaments with approximately 12,000 filaments per strand, primarily used in aerospace and automotive composites. It falls under HTS 6815.11.00.00 as raw carbon fibers for non-electrical uses, distinct from woven fabrics or finished articles. This classification applies to unprocessed fiber tows before further manufacturing into prepregs or laminates.

Import Tips

• Verify fiber tensile strength and modulus specs in documentation to confirm non-electrical carbon fiber classification and avoid misclassification as synthetic fibers

• Obtain certificates of analysis from suppliers detailing filament count, sizing type, and tow size for U.S

• Customs compliance

• Beware of common pitfalls like declaring as 'graphite yarn' which shifts to different subheadings; ensure bill of lading specifies 'carbon fiber tow'
