Ensure the supplier provides a Commercial Invoice, Packing List, Certificate of Origin, and a Radiation Safety Declaration. For shipping, CIF (Cost, Insurance, and Freight) is often preferred for medical equipment to ensure the seller covers insurance until the port of destination. However, if you have a reliable forwarder, FOB may offer better cost control. Always check your country's import duties and medical device registration requirements (e.g., ANVISA in Brazil, CDSCO in India) before finalizing the purchase.
