Import Tips
• Tin content must be certified <3% to remain brass (note a); ≥3% Sn shifts to bronze classification under 7409.40
• Pre-cut condenser tube sheets often reclassified as 'articles' under 7419.99; import in full sheets
• Declare UNS C44300 number and ASTM B171 compliance on entry documents
