Singapore vows tariff evasion probe as White House claims $26 billion in lost duties

Prime Minister Lawrence Wong pledged to investigate companies routing goods through the city-state to dodge tariffs, responding to U.S. allegations that Singapore is part of a transshipment network diverting Chinese exports.

Prime Minister Lawrence Wong said Singapore will investigate any efforts by companies to use the city-state to circumvent tariffs and import goods made with forced labor. Speaking at the National Day Rally, Wong acknowledged U.S. concerns over Chinese goods being routed through Southeast Asia and the 12.5 percent tariff imposed on Singapore over forced labor allegations, but stressed the practical limits of the effort. The White House claimed the U.S. loses $19 billion to $26 billion annually to goods transshipped through third countries to avoid import duties. Wong said Singapore will not allow itself to be used as a conduit for illegal trade practices, but noted that given the volume of global goods passing through the country, it cannot trace the entire supply chain behind every product. The statement comes a week after a White House report titled The Great Transshipment Scam flagged Singapore among 40 economies allegedly part of a shadow transshipment network, categorizing it as a smaller opportunistic target with weak-link advantages such as free zones and limited customs enforcement capacity. Singapore has already faced a 12.5 percent tariff since July under a forced labor investigation, affecting about one-third of its domestic exports to the U.S. Wong said Singapore will continue engaging the U.S. to explain its position and noted that trade is increasingly shaped by security considerations rather than free exchange.

How could this affect you

Traced by who's actually in the path of this — not everyone is.

Likely

If your business imports or exports through Singapore

Regulatory scrutiny could tighten on supply chain documentation and country-of-origin declarations, raising compliance costs and inspection delays for shipments routed through the city-state, especially those involving Chinese components or intermediate processing.

Direct

If you sell Singaporean goods to U.S. customers

The existing 12.5 percent tariff on about one-third of Singapore's domestic exports could remain in place or expand, directly increasing landed costs and eroding price competitiveness against suppliers from countries not subject to the levy.

Likely

If you manage Southeast Asian supply chains

U.S. deployment of AI-powered border surveillance and expanded transshipment penalties could force supply chain restructuring to avoid 40 percent penalty tariffs on goods flagged as illegally routed through third countries, affecting cost and sourcing strategies across the region.

Chanakya's Move

Whose move this was, what they're betting on, what could counter it.

Washington is rebuilding its tariff architecture after the Supreme Court struck down its 2025 reciprocal tariffs in February. The forced labor angle gives the administration legal cover that withstood court challenge, and the transshipment narrative lets it pressure Southeast Asian hubs without relitigating trade surpluses. For Singapore, the bet is reputational: pledge cooperation and accept some scrutiny to avoid being lumped with Vietnam or Malaysia as a full-scale tariff target. The city-state runs a trade deficit with the U.S., so it's betting transparency on enforcement beats confrontation. The counter is that domestic U.S. politics reward visible tariff expansion more than nuance, and Singapore's role as a global logistics node makes it structurally hard to prove no evasion ever occurs. Wong's line about being unable to trace every supply chain is acknowledgment that perfect compliance may be impossible to demonstrate, leaving the door open for Washington to keep pressure on.
