Import Tips
• Provide epitaxial readiness certification and surface roughness specs (e.g
• <0.2 nm RMS) to support undoped substrate classification
• Watch for common pitfalls like incorrect declaration as 'semiconductor wafers' leading to Chapter 85; specify 'undoped GaAs' explicitly
• Ensure compliance with REACH and RoHS for arsenide compounds, including safety data sheets for hazardous material handling
