Import Tips & Compliance

• Verify that the rheostat is not used for heating, as that would change classification

• Declare under 8533.39.00.00 as a wirewound variable resistor for motor drives and test benches

• Provide CBSA with specifications showing the ceramic core is for durability, not heating
