Import Tips
• Verify alloy composition meets brass definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates
• Ensure profiles are truly hollow (not tubes/pipes) to avoid reclassification under 7411.21
• Label with exact dimensions and alloy specs to comply with Customs valuation rules
