The U.S. Commerce Department is conducting a national security investigation into imports of semiconductor technology and related downstream products, according to a Federal Register notice put online Monday.
The official document — which calls for public comments on the investigation — further confirms that chips and the electronics supply chain will not be excluded from U.S. President Donald Trump’s tariff plans despite his statement on Friday that many of those products were exempt from his “reciprocal tariffs.”
As part of the probe, the Commerce Department will investigate the “feasibility of increasing domestic semiconductors capacity” in order to reduce reliance on imports and whether additional trade measures, including tariffs, are “necessary to protect national security.”
The investigation encompasses a wide range of items, including chip components such as silicon wafers, chipmaking equipment, and “downstream products that contain semiconductors.”
Semiconductors play a role in essentially every type of modern electronics, giving the investigation massive implications for Trump’s global trade war as he seeks to boost U.S. manufacturing.
While exemptions have been made on a range of electronic products, Trump and some of his officials said over the weekend that the reprieve was temporary and part of plans to apply separate tariffs to the sector.
The semiconductor investigation — first initiated by the secretary of commerce on April 1 — sets the grounds for such tariffs to come into effect.
First, the Commerce Department will allow for public comments on the investigation to be submitted no later than 21 days from Wednesday.
However, on Sunday, Trump reportedly said he will be announcing new tariff rates on imported semiconductors over the next week, and that flexibility will be shown to certain companies.
On the same day, Commerce Secretary Howard Lutnick told ABC News’ “This Week” that separate tariffs for semiconductors and electronic products were coming in “probably a month or two.”
Trump’s Commerce Department cited the probe under Section 232 of the Trade Expansion Act of 1962, which can permit the U.S. president to impose tariffs on the grounds of national security.
The justification is being used for a similar investigation on pharmaceuticals and pharmaceutical ingredients, which was also disclosed on Monday.
The U.S. is heavily dependent on semiconductor technology imported from markets like Taiwan, South Korea, and the Netherlands.
However, for years, Washington has been implementing policies aimed at onshoring more of the semiconductor supply chain, including through industrial policies such as the $280 billion CHIPS and Science Act.
Nvidia, the chipmaker powering much of the artificial intelligence boom, announced on Monday a plan to design and build factories that, for the first time, will produce NVIDIA AI supercomputers entirely in the U.S.
Last month, Taiwan Semiconductor Manufacturing, the world’s largest chip foundry, announced its intention to increase its existing investments in advanced semiconductor manufacturing in the U.S. by an additional $100 billion.

Tesla shares have dropped 7% from Friday’s closing price of $323.63to the $300.71 close on Tuesday ahead of the company’s second-quarter deliveries report.
Wall Street analysts are expecting Tesla to report deliveries of around 387,000 — a 13% decline compared to deliveries of nearly 444,000 a year ago, according to a consensus compiled by FactSet. Prediction market Kalshi told CNBC on Tuesday that its traders forecast deliveries of around 364,000.
Shares in the electric vehicle maker had been rising after Tesla started a limited robotaxi service in Austin, Texas, in late June and CEO Elon Musk boasted of its first “driverless delivery” of a car to a customer there.
The stock price took a turn after Musk on Saturday reignited a feud with President Donald Trump over the One Big Beautiful Bill Act, the massive spending bill that the commander-in-chief endorsed. The bill is now heading for a final vote in the House.
That legislation would benefit higher-income households in the U.S. while slashing spending on programs such as Medicaid and food assistance.
Musk did not object to cuts to those specific programs. However, Musk on X said the bill would worsen the U.S. deficit and raise the debt ceiling. The bill includes tax cuts that would add around $3 trillion to the national debt over the next decade, according to an analysis by the Congressional Budget Office.
The Tesla CEO has also criticized aspects of the bill that would cut hundreds of billions of dollars in support for renewable energy development in the U.S. and phase out tax credits for electric vehicles.
Such changes could hurt Tesla as they are expected to lower EV sales by roughly 100,000 vehicles per year by 2035, according to think tank Energy Innovation.
The bill is also expected to reduce renewable energy development by more than 350 cumulative gigawatts in that same time period, according to Energy Innovation. That could pressure Tesla’s Energy division, which sells solar and battery energy storage systems to utilities and other clean energy project developers.
Trump told reporters at the White House on Tuesday that Musk was, “upset that he’s losing his EV mandate,” but that the tech CEO could “lose a lot more than that.” Trump was alluding to the subsidies, incentives and contracts that Musk’s many businesses have relied on.
SpaceX has received over $22 billion from work with the federal government since 2008, according to FedScout, which does federal spending and government contract research. That includes contracts from NASA, the U.S. Air Force and Space Force, among others.
Tesla has reported $11.8 billion in sales of “automotive regulatory credits,” or environmental credits, since 2015, according to an evaluation of the EV maker’s financial filings by Geoff Orazem, CEO of FedScout.
These incentives are largely derived from federal and state regulations in the U.S. that require automakers to sell some number of low-emission vehicles or buy credits from companies like Tesla, which often have an excess.
Regulatory credit sales go straight to Tesla’s bottom line. Credit revenue amounted to approximately 60% of Tesla’s net income in the second quarter of 2024.

Amazon founder Jeff Bezos unloaded more than 3.3 million shares of his company in a sale valued at roughly $736.7 million, according to a financial filing on Tuesday.
The stock sale is part of a previously arranged trading plan adopted by Bezos in March. Under that arrangement, Bezos plans to sell up to 25 million shares of Amazon over a period ending May 29, 2026.
Bezos, who stepped down as Amazon’s CEO in 2021 but remains chairman, has been selling stock in the company at a regular clip in recent years, though he’s still the largest individual shareholder. He adopted a similar trading plan in February 2024 to sell up to 50 million shares of Amazon stock through late January of this year.
Bezos previously said he’d sell about $1 billion in Amazon stock each year to fund his space exploration company, Blue Origin. He’s also donated shares to Day 1 Academies, his nonprofit that’s building a chain of Montessori-inspired preschools across several states.
The most recent stock sale comes after Bezos and Lauren Sanchez tied the knot last week in a lavish wedding in Venice. The star-studded celebration, which took place over three days and sparked protests from some local residents, was estimated to cost around $50 million.

The Google Doodle is Alphabet’s most valuable piece of real estate, and on Tuesday, the company used that space to promote “AI Mode,” its latest AI search product.
Google’s Chrome browser landing pages and Google’s home page featured an animated image that, when clicked, leads users to AI Mode, the company’s latest search product. The doodle image also includes a share button.
The promotion of AI Mode on the Google Doodle comes as the tech company makes efforts to expose more users to its latest AI features amid pressure from artificial intelligence startups. That includes OpenAI which makes ChatGPT, Anthropic which makes Claude and Perplexity AI, which bills itself as an “AI-powered answer engine.”
Google’s “Doodle” Tuesday directed users to its search chatbot-like experience “AI Mode”
AI Mode is Google’s chatbot-like experience for complex user questions. The company began displaying AI Mode alongside its search results page in March.
“Search whatever’s on your mind and get AI-powered responses,” the product description reads when clicked from the home page.
AI Mode is powered by Google’s flagship AI model Gemini, and the tool has rolled out to more U.S. users since its launch. Users can ask AI Mode questions using text, voice or images. Google says AI Mode makes it easier to find answers to complex questions that might have previously required multiple searches.
In May, Google tested the AI Mode feature directly beneath the Google search bar, replacing the “I’m Feeling Lucky” widget — a place where Google rarely makes changes.
