Import Tips
• Include cross-sectional diagrams in entry docs to prove T-slot shape qualifies as 'other profile', not bar or rod
• Certify temper and alloy grade (e.g
• 6063-T5) to comply with aluminum alloy subheading requirements
• Watch for misdeclaration as parts; extrusions alone stay in 7604 unless assembled
