Import Tips
• Document the alloy composition (90% Cu, 10% Ni) and the profile's non-circular cross-section to distinguish it from tubes
• If the product is a component of a larger riser system, consider whether it is more appropriately classified as a part under Section XVI
• Have engineering specifications ready for CBSA verification
