Import Tips
• Confirm the pipe is unalloyed aluminum with a purity of at least 99% and provide a certificate of analysis
• If the pipe is part of a distillation apparatus of Chapter 84, it may be excluded, so verify the end-use
• Ensure the pipe is not further worked beyond simple cutting, as that could change classification
