Import Tips
• Obtain end-use certificates for nuclear or defense applications to comply with export control regulations like ITAR or EAR
• Verify purity levels (>99% hafnium) via certified assays to avoid reclassification as alloys under Chapter 81
• Ensure proper hazardous material declarations if contaminated with radioactive byproducts from processing
