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.

The U.S. government has rescinded its export restrictions on chip design software to China, U.S.-based Synopsys announced Thursday.
“Synopsys is working to restore access to the recently restricted products in China,” it said in a statement.
The U.S. had reportedly told several chip design software companies, including Synopsys, in May that they were required to obtain licenses before exporting goods, such as software and chemicals for semiconductors, to China.
The U.S. Commerce Department did not immediately respond to a request for comment from CNBC.
The news comes after China signaled last week that they are making progress on a trade truce with the U.S. and confirmed conditional agreements to resume some exchanges of rare earths and advanced technology.

Datadog shares were up 10% in extended trading on Wednesday after S&P Global said the monitoring software provider will replace Juniper Networks in the S&P 500 U.S. stock index.
S&P Global is making the change effective before the beginning of trading on July 9, according to a statement.
Computer server maker Hewlett Packard Enterprise, also a constituent of the index, said earlier on Wednesday that it had completed its acquisition of Juniper, which makes data center networking hardware. HPE disclosed in a filing that it paid $13.4 billion to Juniper shareholders.
Over the weekend, the two companies reached a settlement with the U.S. Justice Department, which had sued in opposition to the deal. As part of the settlement, HPE agreed to divest its global Instant On campus and branch business.
While tech already makes up an outsized portion of the S&P 500, the index has has been continuously lifting its exposure as the industry expands into more areas of society.
Stocks often rally when they’re added to a major index, as fund managers need to rebalance their portfolios to reflect the changes.
New York-based Datadog went public in 2019. The company generated $24.6 million in net income on $761.6 million in revenue in the first quarter of 2025, according to a statement. Competitors include Cisco, which bought Splunk last year, as well as Elastic and cloud infrastructure providers such as Amazon and Microsoft.
Datadog has underperformed the broader tech sector so far this year. The stock was down 5.5% as of Wednesday’s close, while the Nasdaq was up 5.6%. Still, with a market cap of $46.6 billion, Datadog’s valuation is significantly higher than the median for that index.

Stocks tied to the price of ether, better known as ETH, were higher on Wednesday, reflecting renewed enthusiasm for the crypto asset amid a surge of interest in stablecoins and tokenization.
“We’re finally at the point where real use cases are emerging, and stablecoins have been the first version of that at scale but they’re going to open the door to a much bigger story around tokenizing other assets and using digital assets in new ways,” Devin Ryan, head of financial technology research at Citizens.
On Tuesday, as bitcoin ETFs snapped a 15-day streak of inflows, ether ETFs saw $40 million in inflows led by BlackRock’s iShares Ethereum Trust. ETH ETFs came back to life in June after much concern that they were becoming zombie funds.
The price of the coin itself was last higher by 5%, according to Coin Metrics, though it’s still down 24% this year.
Ethereum has been struggling with an identity crisis fueled by uncertainty about the network’s value proposition, weaker revenue since its last big technical upgrade and increasing competition from Solana. Market volatility, driven by geopolitical uncertainty this year, has not helped.
The Ethereum network’s smart contracts capability makes it a prominent platform for the tokenization of traditional assets, which includes U.S. dollar-pegged stablecoins. Fundstrat’s Tom Lee this week called Ethereum “the backbone and architecture” of stablecoins. Both Tether (USDT) and Circle‘s USD Coin (USDC) are issued on the network.
BlackRock’s tokenized money market fund (known as BUIDL, which stands for USD Institutional Digital Liquidity Fund) also launched on Ethereum last year before expanding to other blockchain networks.
Tokenization is the process of issuing digital representations on a blockchain network of publicly traded securities, real world assets or any other form of value. Holders of tokenized assets don’t have outright ownership of the assets themselves.
The latest wave of interest in ETH-related assets follows an announcement by Robinhood this week that it will enable trading of tokenized U.S. stocks and ETFs across Europe, after a groundswell of interest in stablecoins throughout June following Circle’s IPO and the Senate passage of its proposed stablecoin bill, the GENIUS Act.
Ether, which turns 10 years old at the end of July, is sitting about 75% off its all-time high.
