Timing your shipment can save both money and weeks of waiting. Several predictable patterns affect routes from China. Peak season surcharges: January through March, before Chinese New Year, exporters rush to ship, so container and RoRo space tightens and rates rise 20-50%. Book at least 3-4 weeks ahead during this window. After the holiday (usually February), factories and ports restart gradually, causing 2-3 weeks of backlog. Weather effects: Typhoon season (July-September) can delay departures from southern Chinese ports like Shenzhen and Guangzhou. Winter fog and ice affect northern ports like Dalian and Tianjin, slowing loading operations. Destination-side factors: Monsoon seasons can slow port operations in South and Southeast Asia. Holiday periods at destination (e.g., Ramadan in the Gulf, year-end holidays elsewhere) reduce customs staffing and extend clearance times. Practical advice: ask your forwarder for rate calendars, avoid booking right before major Chinese holidays, and build 1-2 weeks of buffer into delivery promises to your customers. Flexible departure ports (Shanghai vs. Ningbo vs. Shenzhen) can also help you find available space.

Comparing headline prices alone will mislead you—quotes often bundle or exclude different items. Build a like-for-like comparison before deciding. Request every exporter to break their quote into: vehicle price, domestic transport in China, export handling and documentation fees, inspection fee, ocean freight to your port, and insurance. Then add what they exclude: your country's customs duty, VAT/GST, port charges, and local delivery. Watch for common padding: "service fees" of 3-8% that appear only in the final invoice, inflated inland transport (a truck from Guangzhou to a port should rarely exceed a few hundred dollars), and freight quotes that assume a shared container while charging you for a full one. Ask each exporter to state validity (7-14 days is normal) and whether the price is FOB or CIF. Once normalized, the cheapest quote usually isn't the lowest number—it's the one with the shortest list of exclusions and the clearest terms.

If there is a minor leak in the lines due to bumps, it is possible that the cooling may not work upon arrival. This is a normal physical loss. The cost of vacuuming, pressure testing, and recharging refrigerant at a local auto repair shop is low and is the buyer's responsibility.
