Import Tips
• Provide UNS N04400 certification; customs requires proof of nickel content exceeding base metal requirements
• Check thickness measurement method (ASTM vs ISO) to avoid disputes over 'plate vs sheet' classification
• Include heat treatment records if annealed, as processing affects tariff if mistaken for cold-worked
