Import Tips
• Include U-bend configuration documentation if applicable, as finned or bent tubes may need special notes
• Ensure cleanliness certification for condenser use to prevent contamination issues at customs
• Cross-check against 7304.39.0030 for tubes over 190.5 mm to avoid size misreporting
