More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the regulator is a simple pressure-reducing valve without automatic closed-loop control
Pressure-reducing valves of base metal are classified in heading 84.81, not as automatic regulating instruments.
If the regulator operates electronically rather than pneumatically
Electronic automatic regulators fall under tariff item 9032.89.00.

Import Tips & Compliance
• Distinguish this automatic regulator from a simple manual valve by documenting its closed-loop sensing and adjustment capability
• Check if the regulator is eligible for duty-free entry under a free trade agreement
• Be prepared to explain to the CBSA why it is not a simple pressure-reducing valve of heading 84.81
