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
