Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the manifold is for a compression-ignition (diesel) engine
This alternative covers parts for diesel engines, which are classified separately from spark-ignition engine parts.
If the manifold is presented as part of a complete outboard motor
When imported as part of a complete engine, the manifold would be classified with the engine itself.

Import Tips & Compliance
• Ensure the casting is declared as a rough casting with only sprues removed and water jacket passages roughed in, as further machining may affect classification
• Provide a detailed product description and engine application to the CBSA to support the tariff classification
• Consider obtaining a ruling from the CBSA in advance if you are unsure about the classification
