Import Tips
• Confirm the UNS N08825 alloy composition with a mill certificate
• Ensure the tubes are not classified as parts of heat exchangers under Chapter 84; if they are specifically shaped for a heat exchanger, they may be classified elsewhere
• Provide detailed specifications, including length and diameter, to facilitate classification
