Satellite Maps: Shanghai’s Supply Chain Standstill

Wait times for at Shanghai marine terminals has increased nearly 75% since the lockdowns began. Delays at the Shanghai terminal have sent ships to neighboring ports in Ningbo and Yangshan, but those ports are beginning to get congested as well.


China has mandated a strict “zero COVID” policy since the onset of the global pandemic, which has led to tight lockdowns across the country whenever cases have started to spike.

Recently, lockdown restrictions have been enacted in major cities like Shenzhen and Shanghai, as China deals with one of its worst outbreaks since Wuhan in December 2019.

These cautionary measures have had far-reaching impacts on China’s economy, especially on its supply chain and logistics operations. Shanghai’s port system, which handles about one-fifth of China’s export containers, is currently experiencing significant delays as a result of the recent government lockdown.


Traffic has been building up at the Shanghai terminal. As of April 19, 2022, over 470 ships are still waiting to deliver goods to China. If you’d like to check out the Shanghai ports most up-to-date traffic, this live map by MarineTraffice provides real-time updates.

Much of these delays are due to transport issues—an estimated 90% of trucks that support import and export activities are currently offline, which is causing dwell time for containers at Shanghai marine terminals to increase drastically.
