Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled into complete junction boxes
Assembled connection boxes with terminals fall under 8536 as complete apparatus rather than individual components.
If for printed circuit boards under 1,000V
PCB-mounted terminals are classified in 8538 for low-voltage connection parts, not high-voltage standalone terminals.
If insulated power cables with integrated terminals
Terminals permanently attached to insulated cables are classified by cable type in heading 8544.

Import Tips & Compliance
• Verify voltage rating exceeds 1,000V with manufacturer certifications to avoid reclassification
• Ensure UL or IEC compliance documentation for customs clearance in electrical safety standards
• Declare material composition accurately to prevent misclassification as low-voltage items
