Singapore's prominent shipping magnate Teo Siong Seng and several other container industry executives find themselves embroiled in fresh legal complications as two separate civil lawsuits filed in US federal court seek to hold them accountable for an alleged price-fixing conspiracy that affected American businesses. The class-action suits, lodged in the District Court for the Northern District of California on June 2 and 9, represent a distinct line of attack from the criminal indictment previously brought by the US Department of Justice, placing these defendants on a new defensive front driven by private American companies seeking financial redress.

Manufacturers and transporters across the United States are taking action through their lawsuits. C.A. Spalding Company, a manufacturing concern, and Daybreak Express, a transportation firm, have separately initiated proceedings to recover millions of dollars they contend they lost as a result of the container cartel's activities over several years. These civil actions complement but remain independent from the Department of Justice's criminal charges, creating a multi-layered legal exposure for the named defendants.

The underlying allegations centre on a sophisticated scheme to manipulate global container markets. Court documents detail how executives at cartel member firms—China International Marine Containers (CIMC), Shanghai Universal Logistics Equipment, CXIC Group Containers, and Singamas Container Holdings, where Teo serves as chief executive—allegedly coordinated to restrict the world's production capacity. These four entities, along with two unnamed manufacturers, together controlled roughly 95 per cent of global standard dry container manufacturing, granting them considerable market power.

The mechanism of their alleged collusion was remarkably deliberate and systematic. Rather than competing on price, the conspirators orchestrated constraints on production output by limiting the daily shifts and operational hours available to each production line manufacturing containers. Most strikingly, they installed 87 video surveillance cameras distributed across 49 container production lines in their facilities to enforce compliance with agreed output quotas, creating an intricate monitoring system designed to prevent any participant from deviating from the cartel's established parameters.

The financial impact on shipping costs was dramatic and immediately visible in market data. Between 2019 and 2021, the price of a standard 20-foot shipping container more than doubled, climbing from approximately US$1,600 to US$3,500. This surge occurred precisely when global supply chains were under stress from pandemic-related disruptions, making the artificial restriction particularly consequential for businesses dependent on container shipments. The timing raises questions about whether the conspiracy exploited supply chain vulnerabilities to extract maximum pricing power.

The cartel members themselves benefited enormously from the inflated prices they maintained. CIMC's container manufacturing division saw its profits skyrocket from approximately 137 million yuan in 2019 to 1.99 billion yuan in 2020, before climbing further to 11.3 billion yuan in 2021—a ninefold increase over just two years. Singamas Container Holdings demonstrated similarly spectacular turnarounds, moving from a net loss of roughly US$110 million in 2019 to a profit exceeding US$186.8 million by 2021, effectively erasing massive losses through the cartel's price maintenance.

The civil lawsuits carry potentially severe financial consequences for the defendants. Both C.A. Spalding and Daybreak Express are petitioning the court for treble damages, a provision under American competition law that multiplies actual proven losses by three. If the defendants are found liable, they could face penalties totalling three times the documented financial harm suffered by these American companies, creating enormous financial exposure and deterrent impact.

The defendants have been formally notified through court summonses issued on June 8 and 11, requiring them to file formal responses within 21 days. Failure to respond could result in default judgments entered against them without further proceedings. Among those named are Mai Boliang, who progressed from CIMC's presidency and chief executive role to chairman in August 2020; Huang Tianhua, serving as CIMC's vice-president; Wan Yongbo, general manager of CIMC's Operation Management Centre; Li Qianmin, general manager of Shanghai Universal Logistics Equipment; and Zhang Yuqiang, CXIC Group Containers' chief executive. All are Chinese nationals. Teo is the sole Singaporean named, alongside Vick Ma, Singamas's marketing director, who is currently fighting extradition proceedings from France to the United States after his arrest in April.

Teo has largely retreated from public-facing leadership roles since the accusations emerged. The 71-year-old has taken extended leave from multiple prominent positions, including his role as executive chairman of Pacific International Lines, the shipping company he leads. His departure extends to his chairmanship of the Singapore Business Federation, membership on the Enterprise Singapore board, and his pro-chancellor position at the National University of Singapore. In a brief public statement on May 28, he indicated he would not seek re-election when his Singapore Business Federation term expires on June 24, after having been elected to the role only weeks earlier on May 20, 2025, following Lim Ming Yan's early departure to lead Changi Airport Group.

Teo's ascension to the Singapore Business Federation chairmanship, though short-lived, marked his return to the apex chamber after previously serving as chairman from 2014 to 2020, having completed three consecutive two-year terms. His sudden withdrawal from these responsibilities underscores the reputational and legal jeopardy created by the allegations. When approached by media regarding the civil lawsuits, Teo declined to comment, maintaining a defensive posture consistent with legal advice one would expect in such circumstances. His singular public pronouncement acknowledged his deliberate decision to step back, framing it as necessary to address the legal matter while protecting the organisations he once led.
