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.

Our bulk discounts are not simply calculated by the number of units, but by shipping batches. Typically, consolidating enough for a 40-foot container (which can hold 2-3 vehicles, depending on size) can waive some logistics fees; purchasing more than 5 units at once triggers tiered discounts.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
