Vietnam’s president heads to New York with as many as 29 commercial agreements in hand, an American goods deficit that has overtaken China’s, and three separate Section 301 proceedings hanging over the relationship.
WASHINGTON, Sept. 18, 2026
Vietnamese President To Lam travels to New York next week for the United Nations General Assembly carrying an unusual diplomatic burden. His country has just become the single largest source of the American goods trade deficit, overtaking China, Mexico, and Taiwan for the first time, and Washington has three open Section 301 investigations that could reshape the terms on which Vietnamese goods enter the United States.
Bloomberg reported Thursday that To Lam will travel from Sept. 20 to Sept. 25, addressing the General Assembly on Sept. 22 and meeting United States government officials, lawmakers, and business leaders while his trade negotiators continue to work on an agreement with Washington under the threat of new tariffs. The itinerary also includes a stop in Canada, where he is expected to meet Prime Minister Mark Carney and parliamentary leaders.
As many as 29 commercial agreements across multiple sectors could be announced on Sept. 23 at a business conference in New York, according to reporting from Vietnamese and regional outlets. The package is widely read as Hanoi’s attempt to demonstrate commercial value to an administration that has spent eighteen months signaling that the bilateral imbalance is unacceptable.
The number that changed the conversation
For most of the past decade, Vietnam’s trade story with the United States was a secondary concern. That ended this year.
The United States goods deficit with Vietnam reached 126 billion dollars in the first half of 2026, a 45 percent increase over the same period in 2025, according to analysis published by the Center for Strategic and International Studies. That figure placed Vietnam ahead of China, Mexico, and Taiwan, the first time the country has topped the list.
The composition of the increase matters more than the headline. Of the roughly 37 billion dollar rise in Vietnamese exports to the United States in the first six months of 2026 compared with the same period a year earlier, more than 32 billion dollars was electronics. CSIS identified the sources as large multinational technology firms operating in Vietnam, including Apple through its contract manufacturer Foxconn of Taiwan, along with Samsung, LG, Fujitsu, and Intel.
This is the central analytical difficulty for American policymakers. The Vietnamese deficit is not primarily the product of Vietnamese state industrial policy. It is substantially the product of American, Korean, Japanese, and Taiwanese firms relocating assembly out of China in response to American tariffs on China, and then shipping the finished product back to the United States. The deficit with Vietnam is, in significant part, a redistributed deficit with China.
CSIS framed the question directly in the title of its analysis, asking whether Vietnam’s soaring deficit makes it a bad actor. The answer implied by the composition data is complicated.
A tariff history in four acts
Vietnam’s applied rate has moved more than almost any other trading partner’s over the past fifteen months, and understanding where it sits today requires tracing the sequence.
The first act was the April 2025 reciprocal tariff announcement, which assigned Vietnam a rate of 46 percent, among the highest applied to any economy.
The second was the framework agreement reached on July 2, 2025, which made Vietnam the third country to conclude a trade arrangement with the administration. That framework set a 20 percent reciprocal rate, added a 40 percent penalty on goods determined to be transshipped, and committed Vietnam to eliminating its own tariffs on United States imports. The transshipment provision, filed under Harmonized Tariff Schedule subheading 9903.02.01, was designed to reach goods merely routed through Vietnam to disguise Chinese origin, and it carries no mitigation mechanism.
The third act was the Supreme Court’s Feb. 20, 2026 decision holding that the International Emergency Economic Powers Act does not authorize presidential tariffs. That ruling vacated the reciprocal rate structure entirely. Vietnam’s applied rate fell from 20 percent to the 10 percent baseline the administration imposed on Feb. 24 under Section 122 of the Trade Act of 1974, the balance of payments authority.
The fourth act was the expiry of that Section 122 authority on July 24, 2026, at the end of its 150 day statutory limit, and its replacement by the new Section 301 forced labor tariff. USTR placed Vietnam in the 12.5 percent tier alongside 44 other trading partners, with a separate 10 percent tier covering 15 partners.
Metal intensive Vietnamese goods additionally carry Section 232 duties, including 50 percent on steel and aluminum, which stack independently on top of the Section 301 layer.
Net effect: Vietnamese goods that faced a threatened 46 percent in April 2025 face roughly 12.5 percent today, with metals content taxed far higher. That is a favorable position relative to where Hanoi feared it would be. It is also an unstable one.
Three open proceedings
The instability comes from what has not been decided.
The first open matter is the structural excess capacity investigation. USTR initiated Section 301 proceedings on March 11, 2026 against sixteen economies including Vietnam, covering sectors that run from aluminum and automobiles through electronics, semiconductors, solar modules, steel, and transportation equipment. The public docket opened March 17, comments closed April 15, and hearings were held in Washington from May 5 to May 8. Bloomberg reported Thursday that the administration is expected to postpone the resulting determination until after the Sept. 24 summit between President Trump and Chinese President Xi Jinping.
The second is the forced labor proceeding, which is concluded as to the initial tariff but which retains an enforcement dimension. USTR examined roughly 60 economies on whether their governments had taken adequate steps to bar imports made with forced labor, and imposed the resulting duties effective July 24.
The third, and the one with the most Vietnam specific risk, is the intellectual property investigation. USTR Ambassador Jamieson Greer initiated a Section 301 investigation of Vietnam following the 2026 Special 301 Report published on April 30, which designated Vietnam a priority foreign country. The designation cited denial of adequate and effective protection of intellectual property rights and denial of fair and equitable market access to persons relying on IP protection. The April report specifically raised inadequate action against online piracy, counterfeit goods, and border enforcement deficiencies. Comments closed on July 2, 2026, and USTR will determine, in consultation with the President, whether responsive action is warranted, which could include tariff and non tariff measures.
Regional reporting indicates the outcomes of the pending investigations are expected in November and may result in higher tariffs.
Priority foreign country designation is the most severe classification available under the Special 301 framework and has historically been reserved for a very small number of economies. It carries a statutory expectation of investigation and, if warranted, action.
What Hanoi is offering
The 29 agreements reportedly under discussion for announcement on Sept. 23 represent the commercial half of Vietnam’s strategy. The diplomatic half has been steady engagement, including the reaffirmation of commitment to trade negotiations that both governments issued at the end of August.
Vietnam has also benefited from movement on the export control side. The Diplomat reported in February that the United States would remove Vietnam from an export control list, a step that eases access to certain American technology and that Hanoi has treated as evidence of good faith on both sides.
The structural concession Vietnam made in the July 2025 framework, eliminating its own tariffs on American goods, remains the largest card it has played. It removes the most obvious American complaint about market access, though it does nothing about the deficit, which is driven by import demand in the United States rather than by Vietnamese barriers.
What Hanoi has not been able to offer is a credible mechanism for reducing the electronics deficit, because the firms generating it are not Vietnamese and do not answer to the Vietnamese government.
Reactions and stakes
The Vietnamese government has publicly emphasized continuity of negotiation rather than confrontation. Vietnamese customs authorities are expected to begin technical consultations on binding provisions and enforcement mechanisms related to the transshipment rules, a process that will determine how much of the 40 percent penalty tier actually bites.
American industry views are divided by sector.
Apparel, footwear, and furniture importers, who moved significant production to Vietnam over the past decade, have consistently argued that Vietnamese sourcing is a legitimate response to American policy and should not be penalized for succeeding. The National Retail Federation and the American Apparel and Footwear Association have made versions of this argument in comments on multiple proceedings.
Domestic steel and solar producers take the opposite position, arguing that Vietnamese output in those sectors reflects Chinese capital and Chinese input material, and that the transshipment rules as written are too easy to satisfy through minimal processing.
Electronics is the hardest case, because the American firms with the largest exposure are also the firms the administration has been courting for domestic investment commitments.
Economic impact
The macro backdrop limits how aggressive Washington can be without visible cost at home.
The Penn Wharton Budget Model put the average effective United States tariff rate at 6.7 percent as of July 2026, against 2.3 percent in January 2025, with a calendar year 2026 estimate of 7.2 percent. Gross customs revenue from new tariffs reached 298.5 billion dollars between January 2025 and July 2026, before the refunds now flowing out under the post IEEPA CAPE process, which as of July 31 had accepted approximately 128.68 billion dollars in potential and certified refunds for processing.
On the consumer side, the model implies a 1.0 percent short run increase in consumer prices under full passthrough, equivalent to an average household income loss of about 1,338 dollars in 2025 dollars, with bottom quintile filers losing 73 dollars of after tax income in 2026 against 1,868 dollars for the top quintile.
Vietnam’s share of that burden is concentrated in categories with high consumer visibility. Footwear, apparel, furniture, and consumer electronics are precisely the goods where price movement is noticed. A return to a 20 percent Vietnamese rate, let alone anything approaching the original 46 percent, would be felt at retail within two quarters.
There is also a supply chain argument that cuts against escalation. Vietnam absorbed a large share of the production that left China under the previous tariff rounds. Taxing Vietnam at rates approaching Chinese rates removes the economic rationale for that relocation without creating a rationale for returning to the United States, since American labor costs in these categories remain far above both. The likely destination of a third relocation wave is India, Indonesia, Bangladesh, or Mexico, three of which are themselves named in the excess capacity proceeding.
Implications for importers and exporters
Importers sourcing from Vietnam should treat the November window as a planning milestone.
Origin substantiation is the first priority. The 40 percent transshipment penalty turns on whether goods underwent sufficient processing in Vietnam to confer origin. The substantial transformation test is fact specific and documentation intensive. Importers who rely on a supplier certificate without underlying bill of materials, processing records, and value added analysis are exposed. Where the analysis is genuinely close, a binding ruling from Customs and Border Protection obtained before an action is announced is worth considerably more than one obtained after.
Second, review supplier concentration. Firms that moved from China to Vietnam and stopped there have a single point of policy failure. Firms that maintain qualified alternate sources, even at higher unit cost, retain optionality that is difficult to build under time pressure.
Third, examine customs valuation. First sale for export treatment, where the multi tier transaction structure supports it, reduces the dutiable base. At 12.5 percent the saving is meaningful. At 20 percent or above it is material to gross margin.
Fourth, consider bonded and foreign trade zone structures for inventory that serves both domestic and export markets. Duties on re exported goods can be eliminated rather than merely deferred.
Fifth, read intellectual property exposure carefully. If the Special 301 investigation produces an action, its annex may be targeted at sectors associated with the underlying complaint rather than applied across the board. Importers of software embedded products, branded consumer goods, media, and pharmaceuticals should follow that docket specifically.
American exporters to Vietnam are in an unusual position. Vietnam’s commitment to zero tariffs on United States goods under the July 2025 framework survives in principle, though its legal foundation shifted when the reciprocal structure was vacated. Agricultural exporters, aircraft and parts suppliers, energy exporters, and medical device firms have the most to gain from that commitment holding and the most to lose if a tariff action prompts Hanoi to revisit it.
What to watch
Three dates structure the next ten weeks.
Sept. 22 and 23 in New York, when To Lam addresses the General Assembly and the commercial agreements are expected to be announced. The content and value of those agreements will indicate how much political credit Hanoi has been able to buy.
Sept. 24 in Washington, when the Trump and Xi meeting takes place. Vietnam is not a participant, but the excess capacity determination that has been held for that meeting covers Vietnam alongside China, and the rate chosen for Beijing will constrain the rates chosen for everyone else on the list.
November, when the pending investigation outcomes are expected. That is when the question of whether Vietnam’s rate stays near 12.5 percent or moves materially higher will be answered.
Between now and then, the practical posture for importers is to document origin rigorously, avoid irreversible sourcing commitments, and assume that the current rate is a floor rather than a ceiling.
The transshipment question nobody has resolved
The 40 percent transshipment penalty from the July 2025 framework remains the least settled element of the entire relationship, and it is where the largest single tranche of importer risk sits.
The provision was announced with a rate and a tariff subheading but without a definition. What separates legitimate Vietnamese manufacturing from disguised Chinese origin has never been specified in a rule that importers can apply prospectively. The default legal test, substantial transformation, asks whether processing in Vietnam produced a new and different article of commerce with a distinct name, character, or use. That standard has a century of case law behind it, and it produces defensible answers in clear cases and genuine uncertainty in the large middle.
Consider a furniture importer sourcing from a Vietnamese factory that buys Chinese sawn lumber, Chinese hardware, and Chinese finishes, and performs cutting, joinery, assembly, sanding, and finishing in Vietnam. Under conventional analysis that is almost certainly Vietnamese origin. Consider instead a factory that receives Chinese components in kit form and performs screw assembly. That is almost certainly not. The cases in between, where Vietnamese value added is real but modest and the inputs are overwhelmingly Chinese, are where the enforcement risk concentrates.
Vietnamese customs authorities are expected to begin technical consultations on binding provisions and enforcement mechanisms. That process, if it produces a workable certification regime with American recognition, would be the single most valuable outcome of the current negotiating round for importers. If it does not, the 40 percent tier will continue to function as an unquantifiable tail risk that no reasonable compliance program can eliminate.
There is also a penalty dimension. An origin misdeclaration is not merely a duty shortfall. It exposes the importer to penalties under the customs fraud statute, and where the goods were entered over a period of years the accumulated liability can exceed the value of the underlying business.
What the deficit actually tells us
It is worth returning to the composition data, because it bears directly on what policy can reasonably achieve.
If more than 32 billion dollars of a 37 billion dollar increase in Vietnamese exports to the United States is electronics produced by Apple, Samsung, LG, Fujitsu, Intel, and their contract manufacturers, then the deficit is a function of decisions made in Cupertino, Suwon, Santa Clara, and Taipei rather than in Hanoi. Vietnamese policy did not create the flow and Vietnamese policy cannot switch it off.
Three implications follow.
First, a tariff on Vietnam is in economic substance a tariff on American and allied technology firms and, through them, on American consumers. It is not a tariff on a foreign competitor.
Second, the deficit is unusually responsive to a small number of corporate decisions. A change in where a single handset generation is assembled can move the bilateral number by tens of billions of dollars. That volatility makes the deficit a poor target for a policy instrument that takes months to design and years to unwind.
Third, the relocation that produced the Vietnamese deficit was the intended result of earlier American policy. Penalizing it now without offering an alternative destination inside the United States, at costs that would clear in these categories, leaves firms choosing between jurisdictions that are all exposed to the same excess capacity proceeding.
None of this means Washington has no legitimate grievance. The intellectual property record that produced the priority foreign country designation is a separate matter from the deficit, rests on documented enforcement failures, and would justify action on its own terms regardless of the trade balance. The risk is that a deficit driven political impulse and an enforcement driven legal case get bundled into a single tariff, with the result that neither problem is solved and the cost lands on American buyers.
