Under international practices and our standard CIF/FOB terms, the THC at the port of origin (China) is borne by the seller; all THC and port miscellaneous charges incurred at the destination port during unloading are to be paid by the buyer (consignee) upon local customs clearance and pickup.

A realistic timeline: sourcing and negotiation 3-7 days; deposit and booking 1-2 days; pre-shipment inspection 2-4 days; export clearance and vessel booking 7-14 days; sea freight 2-5 weeks depending on destination; import customs clearance and port release 5-10 days. Overall, plan for roughly 5-8 weeks from order to port of destination by sea. For Central Asia and Russia by rail, 2-3 weeks total is common. Tips: ask the exporter for a written schedule with milestones (inspection done, customs cleared, vessel loaded, ETA); track the vessel yourself once you have the container or booking number; and remember Chinese holidays — Chinese New Year and Golden Week can add 1-2 weeks of delay.

The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.
