A ship leaves a container port in the evening in Lianyungang in east China's Jiangsu province Thursday, July 22, 2021.BEIJING — Chinese companies wanting to go global are running into shipping problems.

Access to cheap manufacturing at home gave Chinese businesses an advantage overseas. But it’s turning into a disadvantage now, as the pandemic and trade tensions disrupt international supply channels.

Many goods can’t be shipped out, said Fang Xueyu, vice president of international marketing and general manager for Asia-Pacific at Chinese home appliance company Hisense.

The cost of shipping containers has climbed five-fold from about $3,000 to as much as $15,000 each, while it takes about a week longer for them to get to Europe, she said in a Mandarin-language interview last month.

From the Suez Canal congestion in March to the re-emergence of Covid cases around a major Chinese export hub in Guangzhou in June, logistical disruptions have hit global trade one after the other.

“What you have in Europe, what you have around the world, I wouldn’t call it chaos, but a lot of disturbances in the logistics system,” said Alexander Klose, executive vice president of overseas operations at Chinese electric car start-up Aiways.

“So we had to rebook shifts, we had to delay shifts, because no ships were available, no containers were available. That definitely impacted us,” he told CNBC in an interview in June.

For the company, which makes its cars in China and sells them to Europe, Klose said the disruptions “delayed some shipments by two, three months just because cars were sitting in a port and not being transported.”

Foreign demand for Chinese-made products has remained strong — both by companies’ accounts and official data. The customs agency said in the first half of the year, exports to the European Union rose 35.9% from a year ago to $233 billion, while those to the U.S. climbed 42.6% to $252.86 billion.

Hisense remains keen to expand abroad, and made $7.93 billion in international markets during the pandemic last year. By 2025, the company said it aims to triple the contribution from overseas markets to total revenue to $23.5 billion.

But the shipping delays mark the latest challenge Chinese companies face in trying to reach international markets.

Out of about 3,400 Chinese companies that operate internationally, only about 200 make more than $1 billion in sales overseas, said James Root, a partner at management consulting firm Bain.

“When you dig through it, the early pioneers — the Lenovos, and the Haiers and the Huaweis — to me look more like real exceptions rather than the (avant-garde) who are sort of blazing a trail for lots and lots of Chinese multinationals to follow them overseas,” Root said, referring to three Chinese brands well-known internationally.
