Import Tips

• Confirm exact kVA rating via nameplate and test certificates to ensure classification within 8501.64.0125 (750-10,000 kVA range)

• Provide manufacturer specs showing synchronous AC generator design, excluding photovoltaic types; include CE/UL markings for customs clearance

• Avoid misclassification as complete generating sets (8502) by importing alternator separately from engine; declare as 'other AC generators'
