Import Tips
• ICP-MS analysis certificates required showing <1ppm heavy metals for electronics classification support
• ESD-safe and cleanroom packaging mandatory (Class 1000 minimum) for microelectronics end use
• Particle size distribution documentation (D50 <10μm) prevents resin finishing compound misclassification
