Whatever Trump Means by ‘Transshipment,’ AI Visibility Can Curb Tariff Costs

Guest Insight: Whatever Trump Means by ‘Transshipment,’ AI Visibility Can Limit Tariff Costs

Key takeaways

President Trump's trade frameworks would add a 40% tariff on goods transshipped through Vietnam and other Asian countries to evade higher duties on Chinese-origin products. With "transshipment" still loosely defined, trade lawyer Lenny Feldman explains how AI-driven visibility into product value chains can help importers quantify exposure and prove compliance.

  • U.S. imports of goods transshipped through Vietnam to evade higher duties would face an additional 40% tariff under a trade framework announced by President Trump in July 2025.
  • Illegal transshipment misrepresents a good's Country of Origin to evade tariffs, often by routing goods through a third country with minimal operations or by falsifying documents, a violation that can bring fines, penalties, and jail time.
  • Legal transshipment keeps goods documented and compliant, often under customs control in an intermediate country, so importers pay only the duty owed for the appropriate Country of Origin.
  • Artificial intelligence is already in use by U.S. Customs & Border Protection and can give importers an instant, dynamic map of multi-tier supplier relationships that reveals and quantifies upstream Chinese inputs.
U.S. imports of goods transshipped through Vietnam would be subject to an additional 40% tariff under a trade framework announced by President Trump earlier this month. This provision, also reflected in proposed agreements with other Asian countries, is widely seen as an attempt to prevent Chinese goods destined for the U.S. from circumventing higher tariffs.
“Goods transshipped to evade a higher tariff will be subject to that higher tariff,” the president wrote in nearly identical letters to the leaders of Indonesia, Japan, Malaysia, South Korea, and other trading partners, language that has prompted head-scratching discussion among trade professionals about what ‘transshipped’ means in that context.
Transshipment, at its most basic, refers to the movement of goods between different conveyances, such as airplanes, trains, or trucks, during transit to their final destination. In the context of trade facilitation and enforcement, the term takes on a more specific and often contentious meaning.

Illegal Transshipment: Tariff Evasion and Misrepresentation

Illegal transshipment refers to deceptive efforts to misrepresent a good’s country of origin to circumvent trade regulations and evade tariffs. It can involve physically diverting goods through a third country and performing minimal or no operations there, then claiming that as the country of origin. It can also involve effectively falsifying documents to claim an inaccurate country of origin for goods that haven’t transited through that country.
During the first Trump administration, some manufacturers sought to bypass higher U.S. tariffs on Chinese-origin products by falsely claiming transshipment hubs like Vietnam and Mexico as the country of origin, a violation that can bring fines, penalties, and even jail time.

Legal Transshipment: Documented and Compliant Movement

In contrast, legal transshipment adheres to established guidelines for transferring cargo, ensuring that all goods are properly documented and accounted for and comply with the laws of the destination country. This can involve keeping goods under the control of customs in the intermediate country without letting them enter that country’s commerce, and undertaking only necessary operations like loading, unloading, or activities to preserve the goods’ condition.
Many free trade and preferential trade agreements allow a duty exception for in-transit goods shipped directly through third countries. Evidence such as bills of lading showing the U.S. as the final destination supports these claims. If goods are legally transshipped, importers are subject only to the duty applicable to imports from the appropriate country of origin.

Implications of the U.S.-Vietnam Agreement

According to President Trump’s July 2 Truth Social post, goods transshipped through Vietnam to the U.S. will be subject to a 40% percent tariff. The administration has yet to unveil a precise interpretation of “transshipped,” but members of the trade community speculate it will be broader than merely goods rerouted through Vietnam and relabeled with that as the country of origin.

Regardless of the technical details, if the president’s threat of additional tariffs on transshipped goods remains in a final deal, U.S. importers can expect enhanced enforcement of country of origin rules in both the U.S. and intermediary countries like Korea, Taiwan, Thailand, and Vietnam. This could include closer scrutiny of trade documentation, increased inspections of manufacturing facilities, and stricter monitoring of supply chains linked to China.
To remain compliant and competitive, enterprises and logistics service providers will need visibility deep into product value chains, which are the multi-tier network of materials, components, and human inputs from the soil to the store shelves that make up a finished good. That will enable them to quantify exposure to transshipment tariffs and find alternative suppliers to reduce tariff exposure.
Artificial intelligence — already in use by U.S. Customs & Border Protection — can give importers and logistics service providers an instant, dynamic map of N-tier relationships at the product level, revealing and quantifying upstream Chinese inputs. Importers will also need the ability to collaborate with upstream suppliers and government agencies to validate country of origin, make strategic investments, discover alternative suppliers, and gather and share documentation to prove compliance.
The ambiguity surrounding the definition of ‘transshipment’ under these frameworks illustrates the need for continued vigilance and flexibility in an evolving global trade landscape. The administration is redrawing the lines between legitimate and illegitimate trade practices, potentially leading to significant economic disruption for intermediary countries and upheaval for global supply chains. In that dynamic trade environment, enterprises and LSPs can gain a competitive advantage by embracing AI and other technology solutions.

FAQs

  • The Trump administration has not yet unveiled a precise definition of "transshipped," which has prompted debate among trade professionals. Many in the trade community expect the interpretation to be broader than goods simply rerouted through Vietnam and relabeled with that Country of Origin. The ambiguity itself underscores the need for vigilance as the U.S. redraws the lines between legitimate and illegitimate trade practices.

  • Illegal transshipment is a deceptive effort to misrepresent a good's Country of Origin to circumvent trade rules and evade tariffs, such as routing goods through a third country with little or no real operations. Legal transshipment follows established guidelines, keeps goods properly documented, and complies with the destination country's laws. With legal transshipment, importers pay only the duty owed for the goods' true Country of Origin.

  • AI can give importers and logistics service providers an instant, dynamic map of multi-tier supplier relationships at the product level, revealing and quantifying upstream Chinese inputs. That visibility lets them measure their exposure to transshipment tariffs and find alternative suppliers to reduce that exposure. The same AI tools are already in use by U.S. Customs & Border Protection.

  • Under a trade framework President Trump announced in July 2025, U.S. imports of goods transshipped through Vietnam to evade higher duties would face an additional 40% tariff. The provision, echoed in proposed agreements with other Asian countries, is widely seen as an effort to stop Chinese goods bound for the U.S. from circumventing higher tariffs.

  • Importers can prove compliance with documented evidence, such as bills of lading showing the U.S. as the final destination for goods shipped directly through a third country. As enforcement tightens, they will also need deep visibility into their product value chains and the ability to collaborate with upstream suppliers and government agencies to validate Country of Origin and share supporting documentation.
