PMMA Plastic Optical Fiber Core from Japan
A core strand made from polymethyl methacrylate (PMMA) used as the light-transmitting medium in plastic optical fiber assemblies. It falls under HTS 9001.10.0050 as a plastic optical fiber, distinct from glass fibers or complete cables of heading 8544. These fibers are unmounted and designed for data transmission in short-distance networks.

Import Tips
• Verify optical attenuation specs and material composition (PMMA vs. polycarbonate) to confirm classification under plastic fibers
• Provide test reports distinguishing from glass fibers; ensure not bundled into cables qualifying for 8544
• Label as 'optical fibers' not 'cables' to avoid misclassification; common pitfall is undervaluing based on lightweight plastic
