Import Tips
• Include ASTM A312 or A213 material certificates specifying TP310 grade to prove heat-resisting properties
• Document cold-reduction process via manufacturing records; pitfall is confusion with standard stainless under 7304.41
• Check for pressure vessel certification (e.g
• PED); bulk shipments often require additional NDT test reports
