“Terminals are allowing shipping carriers only a limited capacity for empty boxes and are focusing on transporting loaded containers,” Kuehne + Nagel International AG, one of Europe’s largest freight forwarders, said in an e-mailed reply to questions. “Containers are piling up at the terminals, and more and more containers cannot be returned on departures, including those to Asia.”
Although authorities in Shanghai lifted restrictions this month, shortages of vessels and delays at European ports are forcing export goods to compete with empty boxes for space on ships headed to China, threatening to send a further wave of disruption to Asia, logistics firms said.
