medium: The lockdown dates and the statement that the port kept working are supported by a carrier advisory and by reporting of the city government's own announcement, but we could not retrieve a city or port authority page stating the 2022-03-28 start directly. The window does not overlap Lunar New Year or China's National Day holiday exclusions, though it runs for more than 28 days, so the year ago comparison applies.
First reported
2022-04-06 (6 April 2022)
  • Severity basis: Landside access to the principal container port of China was restricted for more than two months, the closest non measured criterion to a port level restriction of seven days or more, since the terminals themselves stayed open.

What happened

Shanghai began a staged COVID-19 lockdown on 2022-03-28 (28 March 2022), starting in Pudong and extending to the rest of the city from 2022-04-01, and lifted citywide restrictions on 2022-06-01 (1 June 2022). The container terminals at Yangshan and Waigaoqiao kept working under closed loop arrangements, and the carrier Maersk reported in early April that terminal operations continued without delay. The restriction fell on the landside: trucking capacity into and out of the city was cut by driver shortages, testing and quarantine rules, and warehouses inside locked down areas stopped work. Carriers shifted boxes to barge and rail and omitted some calls. The city said normal production and daily life would resume from 2022-06-01, and trade press reported container work close to normal levels in early June.

This is a measured change in public data during the event window, compared with a baseline before it. It shows timing, not cause. We describe an event as causing a change only when an official source says so.

Timeline

  1. A staged lockdown begins in Pudong, the district that holds part of the port's landside operations, and extends to the rest of the city from 2022-04-01. [s1]
  2. Maersk reports that the Yangshan and Waigaoqiao terminals are operating normally for vessel, yard and gate work, while trucking capacity is reduced and warehouses inside locked down areas are affected. No Shanghai calls had been cancelled at that point. [s1]
  3. The city government says normal production and daily operations will resume from 2022-06-01, with public transport restarting and most residents free to leave their compounds. [s2]
  4. Citywide restrictions are lifted. [s2]
  5. Trade press reports Shanghai handled just over 3.4 million TEU in May against a normal month of close to 4 million, with container ship calls down 16 percent against May 2021, and waiting times back near seasonal norms as trucking recovered. [s3]

Cause

The restrictions were COVID-19 control measures ordered by the Shanghai city government during an Omicron outbreak, lifted when the city said the outbreak had been brought under control. Attributed by: Shanghai Municipal People's Government. [s2]

Resolution

2022-06-01 (1 June 2022): The city lifted citywide restrictions from 2022-06-01 and removed limits on which businesses could reopen. Container work at the port returned close to normal levels over the following days, with trucking the slowest part to recover. [s2] [s3]
