Import Tips
• Battery manufacturers should provide weld strength test data and material compatibility (Al-Cu tabs) specs
• Declare EV supply chain status for potential duty exemptions; include REACH/RoHS certificates
• Avoid misclassification as resistance welder (8515.39) by documenting friction-based mechanism
