Before placing an order, verify the authenticity of the Siemens part number and request the original CE test report or Siemens conformity documentation. Cross‑check the serial number on the module against Siemens’ official spare‑part catalogue to ensure it is a genuine component. Confirm that the listed warranty of twelve months is backed by a written guarantee from the supplier.
Discuss the preferred Incoterms with the supplier, such as FOB Xiamen or CIF Shanghai, and ensure payment terms like T/T are clearly defined. The listed lead time of one to two working days suggests rapid dispatch, but ask for a confirmed shipping schedule and any potential customs clearance assistance. Verify whether the supplier can arrange container consolidation if larger quantities are required.
Arrange for a pre‑shipment inspection by an independent third‑party agency to check the module’s functional integrity and visual condition. Request a test report that confirms the 24 V DC input performance and the 32‑point operation meets Siemens specifications. Ensure that the supplier provides a commercial invoice, packing list, and CE certificate as part of the export documentation.
