Import Tips
• Provide calibration certificates and technical drawings illustrating semiconductor strain gauge elements for CBP review
• Distinguish from mechanical sensors by highlighting silicon micromachining processes in declarations
• Bundle in anti-static packaging; declare as ESD-sensitive to qualify for proper handling during customs clearance
