Import Tips
• Secure DOE/NRC import authorization for nuclear materials; standard tariff entry requires end-user statements
• Document hafnium isotopic purity (low neutron absorption variants) to support 'pure hafnium' classification
• Avoid classifying as 'parts of nuclear reactors' (HTS 8401) by specifying as hafnium metal article
