Trump’s threatened 40% tariff on ‘transshipped’ goods tries to target China and its manufacturing strength

As the United States ramps up tariffs on major trading partners globally, President Donald Trump is also disrupting strategies that could be used—by Chinese companies or others—to circumvent them.

Goods deemed to be “transshipped,” or sent through a third country with lower export levies, will face an additional 40% duty under an incoming wave of Trump tariffs Thursday.

The latest tranche of “reciprocal” tariff hikes, taking aim at what Washington deems unfair trade practices, impacts dozens of economies from Taiwan to India.

The transshipment rule does not name countries, but is expected to impact China significantly given its position as a manufacturing powerhouse.

Washington likely wants to develop supply chains that are less reliant on China, analysts say, as tensions simmer between the world’s two biggest economies and the U.S. sounds the alarm on Beijing’s excess industrial capacity.

But “it’s a little more about the short-term effect of strengthening the tariff regime than it is about a decoupling strategy,” said Josh Lipsky, chair of international economics at the Atlantic Council.

“The point is to make countries worried about it and then have them err on the side of not doing it, because they know that Trump could then jack up the tariff rates higher again,” he added, referring to tariff evasion.

The possibility of a sharply higher duty is a “perpetual stick in the negotiations” with countries, said Richard Stern, a tax and budget expert at the conservative Heritage Foundation.

He told AFP that expanding penalties across the globe takes the focus away from Beijing alone.

Alternative supplies

Experts have noted that Vietnam was the biggest winner from supply chain diversions from China since the first Trump tariffs around 2018, when Washington and Beijing engaged in a trade war.

And Brookings Institution senior fellow Robin Brooks pointed to signs this year of significant transshipments of Chinese goods.

He noted in a June report that Chinese exports to certain Southeast Asian countries started surging “anomalously” in early 2025 as Trump threatened widespread levies.

While it is unclear if all these products end up in the United States, Brooks cast doubt on the likelihood that domestic demand in countries like Thailand and Vietnam rocketed right when Trump imposed duties.

“One purpose of the transshipment provisions is to force the development of supply chains that exclude Chinese inputs,” said William Reinsch, senior adviser at the Center for Strategic and International Studies.

“The other purpose is to push back on Chinese overcapacity and force them to eat their own surpluses,” he added.

But Washington’s success in the latter goal depends on its ability to get other countries on board.

“The transshipment penalties are designed to encourage that,” Reinsch said.

Lipsky added: “The strategy that worked in the first Trump term, to try to offshore some Chinese manufacturing to other countries like Vietnam and Mexico, is going to be a much more difficult strategy to execute now.”

China response?

Lipsky noted that Beijing could see the transshipment clause as one targeting China on trade, “because it is.”

“The question is, how China takes that in the broader context of what had been a thawing relationship between the U.S. and China over the past two months,” he added.

While both countries temporarily lowered triple-digit tariffs on each other’s exports, that truce expires August 12.

The countries are in talks to potentially extend the de-escalation, although the final decision lies with Trump.

It will be tough to draw a line defining product origins, analysts say.

Customs fraud has been illegal for some time, but it remains unclear how Washington will view materials from China or elsewhere that have been significantly transformed.

The burden lies with customs authorities to identify transshipment and assess the increased duties.

“That will be difficult, particularly in countries that have close relations with China and no particular incentive to help U.S. Customs and Border Protection,” Reinsch added.
