Import Tips
• Provide ASME SA-213 certification showing boiler end-use; inspectors often reject without material traceability
• Conduct hydrostatic test records pre-shipment to demonstrate pressure integrity, avoiding detention
• Note exact wall thickness in invoices, as thin walls might be scrutinized for heat exchanger vs general use
