Import Tips & Compliance

• Ensure the electrostatic precipitator is classified as a complete gas filtering machine, not as a part of the power plant

• Provide detailed specifications of the collection efficiency and flue gas flow rate for CBSA review

• Consider whether the unit is eligible for reduced duty under environmental goods agreements
