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
