Import Tips
• PH grades may border stainless classification; provide detailed chemistry certs showing precipitation-hardening treatment
• Avoid rust/discoloration claims at entry per chapter note—no duty allowance for surface conditions
• Document as 'not cold-formed' explicitly in commercial invoice for smooth CBP processing
