Import Tips
• Measure the foil thickness and width to confirm it meets the definition of plates, sheets, or foil under the chapter notes
• Provide documentation showing the hafnium content exceeds 99% by weight if claiming 'not alloyed' status
• Consider whether the foil is further processed (e.g
• perforated or coated) which could affect classification
