Import Tips & Compliance
• Ensure the alloy composition is clearly documented (70% Cu, 30% Ni) to support classification
• Provide a detailed description of the profile's cross-section shape to confirm it is not a tube
• If the profile is part of a chemical reactor, consider whether classification under Section XVI is more appropriate
