Import Tips & Compliance
• When importing, clearly indicate the alternator's output in kVA and its function as an AC generator to justify classification under 8501.64.00
• Keep records of the static excitation system's specifications, as this may be relevant for CBSA verification
• Consider whether the generator is part of a larger system that could affect classification
