Trump 40% Transshipment Tariff Targets China Supply Chain Loopholes

The Trump administration has introduced a 40% tariff on so-called “transshipped” goods, a measure designed to close loopholes that allow Chinese manufacturers to circumvent U.S. trade restrictions by routing products through third countries. This move, part of a broader wave of tariffs announced in late August 2025, signals Washington’s intent to target China’s manufacturing dominance while reinforcing its global tariff regime [1]. The policy does not name specific countries but is widely expected to have a significant impact on Chinese exporters, who have increasingly used transshipment strategies to maintain access to the U.S. market after earlier tariff impositions [1].

The transshipment rule is one of several measures introduced as the U.S. seeks to reshape global supply chains away from China. Analysts suggest the policy is less about long-term decoupling and more about reinforcing a short-term tariff deterrent. “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,” said Josh Lipsky of the Atlantic Council [1]. This strategy aims to deter trade practices that the administration views as evasions of its broader tariff strategy.

The move is also seen as a response to concerns over China’s industrial overcapacity, with the U.S. aiming to push back by making it more expensive for Chinese goods to enter the global market through alternative routes. William Reinsch of the Center for Strategic and International Studies noted that the transshipment provisions are intended to force supply chains to exclude Chinese inputs and to reduce Beijing’s ability to export surpluses [1]. However, the success of this goal will depend on cooperation from other countries, many of which have close economic ties with China and may resist U.S. pressure.

The impact of the transshipment rule is already evident in global trade patterns. Experts have noted that Vietnam, for example, was a major beneficiary of supply chain shifts following the first round of Trump-era tariffs in 2018. More recently, Robin Brooks of the Brookings Institution observed signs of increased transshipment activity in 2025, with Chinese exports surging to Southeast Asian countries like Thailand and Vietnam ahead of new tariff measures [1]. While it remains unclear whether all these goods eventually reach the U.S., the trend suggests that Chinese exporters are adapting to the evolving tariff landscape.

The administration’s strategy has drawn mixed reactions internationally. India, for example, has criticized the proposed tariffs as “unjustified,” accusing the U.S. of applying a double standard in its trade policies [2]. Meanwhile, global supply chain managers are bracing for increased complexity and costs as customs authorities ramp up enforcement of transshipment rules. Reinsch noted that identifying transshipment cases will be difficult, particularly in countries with close relationships with China [1].

As part of its broader trade strategy, the Trump administration has also imposed or threatened higher tariffs on a range of other goods and countries, including 50% duties on Brazilian goods and 35% tariffs on Canadian imports. The administration has also ended the de minimis exemption on low-value imports under $800, a move that could affect e-commerce and consumer purchasing habits [2]. These measures, combined with the transshipment tariff, are reshaping global trade dynamics and forcing businesses and governments to reassess their strategies in response to the evolving U.S. trade environment.
