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.

Rust is a deal-breaker that photos can hide, so be systematic. High-risk areas to check: 1. Underbody and frame rails—surface rust is normal, but flaking or bubbling paint means advanced corrosion 2. Wheel arches and rocker panels—these trap mud and salt 3. Door bottoms and the trunk floor—water collects here; lift the trunk mat and look for dampness or repair welds 4. Around the windshield and sunroof drains—leaks cause hidden rust in the A-pillars Ask the inspector to do a magnet test: filler-repaired areas won't hold a magnet, indicating past accident repairs. A paint thickness gauge reveals resprayed sections—uniform readings around 80-150 microns are normal; spikes over 300 suggest bodywork. Cars from northern China (salted roads in winter) or coastal cities need extra scrutiny on the underbody. If structural members show corrosion, walk away—repairs rarely restore original strength.
