Samsung and Tesla have asked Washington not to slap new tariffs on Vietnam, just weeks before a US trade probe reaches its November 29 deadline. Their filings show how much of the phone and car supply chain now runs through Vietnam.
Steel, solar and seafood producers want the opposite. Here is what each side argued, what Vietnam already pays, and why India is watching closely.
What is the US probe into Vietnam, and when is the deadline?
It is a Section 301 investigation into Vietnam’s protection of intellectual property, opened by the US Trade Representative (USTR) on May 29, 2026. Reuters reports the Trump administration has set November 29 to conclude it. Possible outcomes include tariffs, other trade measures, or no new action at all.
The probe followed a rare step. On April 30, the USTR named Vietnam a “priority foreign country” in its Special 301 Report. Reuters says Vietnam is the first jurisdiction in 13 years to land in that most serious watchlist category.
The US accuses Vietnam of “a persistent failure to resolve long-standing concerns about IP protection and enforcement.” The official notice lists online piracy, counterfeiting, weak border checks, unlicensed software and cable signal theft. Public comments closed on July 2.
One caveat: November 29 is a decision date, not a tariff start date. EconoTimes notes that the law allows a three-month extension in some cases. Reuters also says it is unclear whether any duty would be general or limited to specific sectors.
Why do Samsung and Tesla fight Vietnam tariffs?
Both say a tariff would punish manufacturers, not pirates. Tesla urged the USTR to “take into account the supply chain needs of American manufacturers,” Reuters reports. Samsung’s US unit said Vietnam produces a significant share of the Samsung smartphones and network equipment sold in America. Neither company faces any piracy accusation itself.
Tesla’s comments, sent on July 2, said some advanced components and precision manufacturing equipment cannot be sourced in the US despite major investment there. Tesla did not name the parts or put a dollar figure on its exposure, and we will not guess one.
That matters because Tesla has no factory in Vietnam. Vietnamese newspaper Tuoi Tre reports Tesla registered a local sales and distribution company in Ho Chi Minh City on September 11, with $3 million in capital. Its supply-chain worry is about parts and machines, not finished cars. Margins are already under pressure, as our Tesla Q3 2026 results report showed.
Samsung’s stake is far bigger. Reuters calls the Korean company Vietnam’s largest foreign investor, with about $25 billion invested. Its local executives told Vietnamese media in 2026 that the plants make about 50% of the group’s global phone output and employ about 85,000 people.
According to The Investor, its Vietnam arm exported about $39 billion in the first seven months of 2026, roughly 12.2% of all Vietnamese goods exports. Put simply, a tariff on Vietnam is effectively a tariff on Samsung’s phone business.
Who wants new tariffs on Vietnam, and who doesn’t?
The business world is split down the middle. Reuters reports that groups for US producers of steel, seafood, plywood, solar panels and wood products accused Vietnam of unfair practices and want new tariffs. Importers, retailers and device makers with big Vietnamese factories, including Samsung and Tesla, want no new duties at all.
| Group | Position | Reason given (as reported by Reuters) |
|---|---|---|
| Tesla | Against | Some advanced parts and precision equipment cannot be sourced in the US |
| Samsung (US unit) | Against | Vietnam makes a significant share of its US-bound phones and network gear |
| Footwear, apparel, bike and console groups | Against | Members manufacture heavily in Vietnam |
| US steel, seafood, plywood, solar and wood groups | For | Allege unfair practices by Vietnam |
| Business Software Alliance | Wants enforcement | Says about 75% of PC software in Vietnam was unlicensed (2017 survey) |
| Motion Picture Association | Wants enforcement | Says Vietnam-based piracy sites drew over 12.5 billion visits last year |
The copyright groups are interesting. They want concrete anti-piracy commitments from Hanoi, which is not the same as asking for tariffs.
What tariffs does Vietnam already face?
Vietnam already pays a 12.5% US tariff on most goods. The USTR imposed it from July 24, 2026, after a separate forced-labour investigation, according to the Federal Register notice. Before that, Vietnam faced a 20% “Liberation Day” tariff, which the US Supreme Court struck down, Reuters reports
| Item | Detail | Source |
|---|---|---|
| Earlier “Liberation Day” tariff | 20%, struck down by the Supreme Court | Reuters |
| Current general tariff | 12.5%, effective July 24, 2026 | Federal Register |
| Exports to the US, Jan-Aug 2026 | Up 42% year on year | Reuters |
| Rank by US goods surplus | No. 1, ahead of China and Mexico (fourth at end-2025) | Reuters |
| Separate US probe | Alleged excess capacity, still under way | Reuters |
Reuters says many economists believe Washington wants to restore at least the tariff level the court removed. A new IP duty on top of 12.5% would get Vietnam close to that.
Could this affect EVs, auto parts and phones?
Yes, but mostly indirectly for now. Phones are the clearest risk, because Vietnam builds a large share of the Korean giant’s US-bound devices. Cars are less direct. Vietnam is not a major car exporter to America, so any hit would come through electronic parts and factory equipment, which is the exposure Tesla described.
Vietnam’s own carmaker is also watching. VinFast, which is expanding in India, as covered in our VinFast VF5 facelift story, would feel any squeeze on its home economy.
Is India the winner if Vietnam gets hit?
Possibly, and India already starts with a small edge. Under the July forced-labour action, the USTR set a 10% rate for India against 12.5% for Vietnam, according to the USTR and India’s Press Information Bureau. Any new IP tariff on Vietnam would widen that gap for companies choosing where to build US-bound products.
Samsung already runs a huge phone factory in Noida. The Economic Times reported on October 23 that Samsung exported about $2.6 billion of phones from India in the first five months of FY27, and plans more under India’s new phone incentive scheme. But the same report says the company is not moving production out of Vietnam, where its supplier base is far deeper.
India’s export story is growing in vehicles too. Our report on India motorcycle exports in H1 FY2027 showed a 32% jump.

CarBike Insight Analysis
This is a phone story first and a car story second, but the logic applies to both. A tariff meant to punish piracy would fall on factories that have nothing to do with piracy. That is why Samsung and Tesla argue on supply-chain grounds rather than defending Vietnam’s IP record.
Our read: a negotiated deal, with Hanoi promising tougher enforcement, looks more likely than a broad tariff. The opposition from US manufacturers is strong, and targeted action is easier to defend. That is our analysis, not a reported fact.
For India, the opportunity is real but slow. The Vietnam supplier ecosystem took nearly two decades to build, and one tariff will not move it overnight.
Who should care? Indian electronics and auto-parts suppliers looking for US orders, and investors in export-linked manufacturers. Who should wait? Anyone expecting phone or EV prices in India to move. This probe targets US imports from Vietnam, not Indian prices.
FAQ
Why are Samsung and Tesla against new US tariffs on Vietnam?
Tesla says some advanced parts and precision equipment cannot be sourced in the US. Samsung’s US unit says Vietnam makes a significant share of the phones and network equipment it sells in America, according to Reuters.
When will the US decide on Vietnam tariffs?
The Trump administration has set November 29, 2026, to conclude the Section 301 probe, Reuters reports. The decision could bring tariffs, other measures or no action, and US law allows a three-month extension in some cases.
How much has Samsung invested in Vietnam?
Reuters puts Samsung’s investment in Vietnam at about $25 billion, making it the country’s largest foreign investor. Its Vietnam plants make about half of its global smartphone output, its executives told local media this year.
What tariff does Vietnam pay now?
Vietnam currently faces a general 12.5% US tariff, in force since July 24, 2026, after a forced-labour probe. An earlier 20% tariff from Trump’s “Liberation Day” was struck down by the US Supreme Court.
Will this make Samsung phones or Tesla cars costlier in India?
Not directly. The probe concerns US tariffs on goods shipped from Vietnam to America. Indian prices depend on Indian duties and local production, such as Samsung’s Noida factory, which this decision does not affect.
