Import Tips & Compliance
• Confirm the wire meets the definition of 'wire' under section note 9 (coiled, uniform cross-section) to support classification
• Provide a purity certificate showing hafnium content for 'not alloyed' status
• Check if the wire is subject to any export controls or requires special permits for aerospace applications
