Import Tips
• Ensure the powder meets the definition of 'powders' in Section XV Note 8(b) — 90% or more by weight must pass through a 1 mm sieve
• Provide a mill certificate or laboratory analysis to confirm hafnium content and purity
• Declare the product as hafnium powder, not as an alloy, to avoid misclassification
