Import Tips
• Ensure the foil meets the hafnium-to-zirconium ratio of less than 1:500 by weight; provide a mill test certificate from the supplier
• Classify as a sheet or foil product under Chapter 81, not as a part of machinery (Section XVI)
• Verify if the end-use in pharmaceutical vessels triggers any additional health or safety documentation
