Import Tips
• Verify alloy composition meets copper-zinc base alloy definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates
• Ensure NPT threading standards compliance; mismatched threads lead to customs reclassification or rejection
• Provide pressure ratings and plumbing end-use documentation to avoid misclassification as industrial machinery parts
