Import Tips
• Verify power handling capacity documentation (40VA minimum) with manufacturer specs to confirm HTS 8504.31.40.65 classification
• Include UL or CE safety certifications; U.S
• Customs requires proof of compliance for electrical transformers
• Avoid misclassification as power supplies (8504.40) by specifying AC-to-AC transformation function
