Flow Rate Automatic Controllers for Pipelines from Mexico
Instruments that automatically adjust valves to maintain constant flow rates in liquid pipelines using flowmeter feedback and PID algorithms. These automatic regulators for liquid flow variables fall under tariff item 9032.89.00 as they continuously measure and correct flow.

Consumer Products Safety · May be required · on some HTS numbers under this code
May require HC Consumer Products Safety depending on intended use (HC21) and Canadian product category (HC29, HC30, HC31, HC32, HC33, HC34, HC35, HC36, HC37); or intended use (HC22, HC23, HC24, HC26, HC27) and Canadian product category (HC37), and on the full 10-digit classification number (only some numbers under this code are listed). Matching criteria: Equal To 9032890021; Equal To 9032890021. Logic: MATCH IF (Valid HS Code) AND (Intended Use Code) AND (Valid Canadian Product Category).

Import Tips
• Clearly document the PID control functionality to demonstrate automatic regulation rather than simple flow measurement
• Ensure the controllers comply with Canadian pipeline safety standards
• Provide CBSA with flowmeter specifications and control loop diagrams
