Import Tips
• Verify compatibility certification for 6/12/24V systems and include OEM specs in documentation to avoid misclassification
• Obtain automotive aftermarket approvals (e.g
• SAE standards) as common pitfalls include rejection due to missing safety certifications
• Declare as vehicle parts only if not bundled with full alternator; separate entry prevents duty escalation
