Import Tips
• Provide heat transfer performance specs and end-use affidavits to confirm heat exchanger suitability
• Cold-drawn finish requires documentation; otherwise, it might be misclassified as hot-finished
• Check for pressure ratings; tubes not rated for high-pressure service may go to general tube headings
