Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for modular panelboard expansion
Panelboards with similar voltage ratings but focused on lighting/distribution circuits fall under this statistical suffix.
If for voltages exceeding 1,000V
Same assembly type but rated over 1,000V shifts to the higher voltage subheading in 8537.20.
If sold as unassembled parts kit
If imported as loose components without final assembly, classified as individual boards of heading 8538.

Import Tips & Compliance
• Obtain UL 891 or equivalent certification for switchboards to meet NEC standards and avoid CBP holds
• Include detailed wiring diagrams and component lists in documentation to verify apparatus from 8535/8536
• Avoid misclassification as panels by proving integrated control functions; common pitfall is incomplete voltage ratings
