Acrylonitrile Filament Tow for Carbon Fiber Precursor from China
Synthetic filament tow containing 92% or more acrylonitrile units, with fewer than 70,000 filaments each of 1.59 decitex diameter or less, used as precursor material for carbon fiber production. This tow meets the precise filament count and diameter specifications outlined in HTS 5501.30.00.10, distinguishing it from broader acrylic tows.

Import Tips
• Verify filament count (fewer than 70,000 ±2000) and diameter (1.59 decitex ±0.027) via lab testing certificates to match HTS 5501.30.00.10 specs
• Provide manufacturer specs confirming ≥92% acrylonitrile content; mismatches may reclassify to 5501.30.00.00
• Declare as 'separable tow' if applicable, with documentation showing capability for division into qualifying sub-tows
