Seven Chinese executives and four of the world’s largest shipping container manufacturing companies were indicted for conspiring to restrict the output of — and fix the prices of — nearly all of the world’s standard unrefrigerated shipping containers for over four years, spanning as early as November 2019 to at least January 2024, in violation of Section 1 of the Sherman Antitrust Act.
The multi-year conspiracy roughly doubled the prices of standard shipping containers between 2019 and 2021, increasing the container manufacturers’ profits approximately one hundredfold during the COVID-19 pandemic and global supply chain crisis. One executive, Vick Nam Hing Ma, was arrested and his extradition to the United States is pending. Six executive co-defendants remain at large.
Defendant Vick Nam Hing Ma, also known as “Vick Ma”, “馬南慶” and “马南庆” in Chinese, 54, of the People’s Republic of China, was employed by Singamas Container Holdings Ltd. as Marketing Director. He was arrested on April 14, 2026, in France and his extradition to the United States is pending. Following Ma’s arrest, the U.S. District Court for the Northern District of California unsealed today a superseding indictment charging Ma and 10 of his co-conspirators for conspiring to restrict the output of—and fix the price of — nearly all the world’s standard unrefrigerated shipping containers (also known as standard dry containers), the intermodal containers which carry billions of dollars of goods across the oceans to American households each year. In total, the superseding indictment charges 11 defendants, including 10 of Ma’s co-conspirators.
As alleged in the superseding indictment, as early as March 2019, several of the conspirators began discussing a scheme to restrict the output and fix the prices of standard dry shipping containers. On or about Nov. 14, 2019, Yongbo Wan and Tianhua Huang of CIMC, Qianmin Li of Dong Fang, Yuqiang Zhang of CXIC, and a co-conspiring executive of Co-Conspirator Company A met at CIMC’s headquarters in the city of Shenzhen. The goal of the agreement was to raise the price of standard dry shipping containers. To do so, they agreed to restrict CIMC’s, Dong Fang’s, CXIC’s, and Co-Conspirator Company A’s output of standard dry shipping containers by various means, including:
- Limiting the number of shifts and hours that each production line for standard dry containers could run per day;
- Installing 87 video surveillance cameras on all 49 dry container production lines to ensure that the companies did not exceed the agreed-upon limitations;
- Not building any new container manufacturing factories; and
- Establishing a fund that included a mechanism to penalize financially any cheating on the output-restriction agreement.
The participants contemplated that Singamas and Co-Conspirator Company B would join the output-restriction agreement later. Those companies did so by at least as early as March 2020.
Throughout their conspiracy, the conspirators refined the operation of the output-restriction agreement. By September 2020, the conspirators agreed to restrict how many standard dry shipping containers the company conspirators would manufacture for particular customers. These customers included major U.S.-based container lessors, shipping lines, and logistics companies, in addition to container lessors, shipping lines, and logistics companies based in Europe, the People’s Republic of China, and elsewhere. And from at least as early as September 2022 until at least as late as November 2023, the conspirators agreed to cap the total cargo volume of containers that the company conspirators produced.
On or about November 20, 2023, for example, Vick Ma of Singamas co-presented to his CEO, co-defendant Siong Seng Teo, the conspiracy’s “Total Allowable capacity” and “allowable quota” for production — organized by each company conspirator and its factory lines.
As further alleged in the indictment, the profits of CIMC’s container manufacturing business segment increased nearly one hundredfold from about $19.8 million USD in 2019, to about $288 million USD in 2020, to about $1.75 billion USD in 2021. Singamas’s net income increased from a loss of about $110 million USD in 2019, to profits of about $4.6 million in 2020 and about $186.8 million in 2021.
