Import Tips
• Use independent lab analysis for Mo/Ni verification if mill certs are questioned by CBP
• Ensure no cladding/coatings applied; such 'further working' per Chapter notes changes classification
• Document thickness precisely (3-4.75mm) as gauge variations can trigger adjacent subheadings
