Import Tips
• Provide OEM specifications confirming dielectric properties match 8501.64.0110 generator voltage classes (typically 3-15 kV)
• Include end-user statements from generator manufacturers verifying exclusive use in qualifying alternators
• Document thickness, thermal class (F/H), and pressboard composition to distinguish from generic electrical insulation
