Import Tips
• Include ASME Section II material certs and non-destructive testing (NDT) reports for pressure vessel compliance
• Specify if normalized/heat-treated; advanced processes don't change HTS but aid valuation
• Ship in protective racks; damage during transit can lead to rejection for high-pressure apps
