Import Tips
• Include chemical analysis report showing zinc predominance and tin <3% to avoid bronze misclassification under 7409.22
• Coils must be verified as wound form >5mm thick; uncoiled shipments may require 7407 classification
• Label with UNS number (C46400) and thickness; customs audits often check against declared HTS specs
