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.
