Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the vacuum pump is a general-purpose pump not specific to flashbulb sealing
Vacuum pumps are classified under heading 84.14 when they are not identifiable as parts of a specific machine.
If the pump is part of a machine with a function not covered elsewhere
Machines having individual functions, not specified elsewhere in Chapter 84, are classified under heading 84.79.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Declare the vacuum pump as a part of flashbulb sealing machines, not as a general-purpose pump under heading 84.13
• Provide CBSA with technical specifications showing its specialized use in glass envelope sealing
• If the pump is imported with the sealing machine, it may be classified as part of the complete machine rather than as a separate part
