Import Tips
• Provide cleanroom compatibility certification (ISO Class 1-5) and load ratings in documentation
• Declare exact roller diameter and pitch; avoid bundling with motors to prevent parts-of-machine classification
• Include material certificates (e.g
• stainless steel 440C) for traceability in high-tech imports
