Import Tips
• Certify arc tolerances to ±0.01mm for generator applications to support specialized classification
• Declare radiation tolerance if applicable, avoiding confusion with Chapter 85 radiation-hardened items
• Ship in nitrogen-flushed containers to prevent surface oxidation affecting performance
