Import Tips
• Verify the glass material composition and dielectric strength certification to confirm classification under 8546.10
• Include test reports for puncture and flashover voltage compliance as required by NEMA and IEC standards
• Avoid misclassification by ensuring no metal fittings are imported separately; complete assemblies stay in this code
