Import Tips
• Include breakdown voltage specifications; small diacs often scrutinized for proper HTS declaration
• Ship in anti-static packaging with ESD protection certification required for semiconductor imports
• Avoid bundling with triacs in sets; individual components maintain 8541.30 classification
