Import Tips
• Submit a certificate of conformance for the 7178-T651 alloy and temper
• Ensure the product is described as a hollow profile, not a tube, by checking the cross-section shape and wall thickness
• If the profile is for aerospace use, consider whether it qualifies for duty relief under the Canadian Aerospace Industry program
