Import Tips
• Include ASME material certification and heat treatment records to substantiate boiler tube classification
• Declare exact grade (P11, P22, etc.) as it affects alloy content verification during customs exam
• Watch for inadvertent classification as carbon steel (7304.39) due to insufficient chromium/molybdenum documentation
