Not sure which classification is right?
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
• Measure the external diameter precisely to confirm it exceeds 406.4 mm, as pipes at or below this threshold fall under a different tariff item
• Ensure the pipe is made of nonalloy steel to avoid classification as alloy steel
• Provide technical drawings or specifications to the CBSA for verification
