Import Tips
• Supply solution-annealed condition certification to prove semi-finished status before age-hardening treatments
• Label with precise diameter (e.g
• ~172 mm for 232 cm²) to match circular cross-section requirement
• Comply with aerospace import specs like AMS 5643 alongside HTS documentation
