Import Tips
• Provide chemical compatibility certificates for solder mask formulations to demonstrate specialized PCB use
• Include PCB production line integration diagrams in documentation to support 'solely or principally' classification criterion
• Avoid misclassification by excluding units with manual spray guns; ensure fully mechanical operation
