Will Trump’s 25% Iran tariffs push up prices on China-made tech?

US President Donald Trump on Monday announced a sweeping 25% tariff targeting countries that do business with Iran – a move that, despite lacking any implementation details, could drive up the cost of phones, laptops, and other everyday tech devices made in China.

Trump’s, at this stage, theoretical tariff threat appears aimed at showing support (without committing to military action) for the tens of millions of Iranians now moving into their 17th day of nationwide protests against the repressive Islamic regime.

Iran has been in a widespread digital blackout since last Thursday, albeit with some Starlink connectivity, and reports now of more than 600 Iranians killed so far by security forces loyal to Supreme Leader Ayatollah Ali Khamenei.

“Effective immediately, any Country doing business with the Islamic Republic of Iran will pay a Tariff of 25% on any and all business being done with the United States of America. This Order is final and conclusive. Thank you for your attention to this matter!“ the President posted about 5:00 p.m. Eastern Time Monday on Truth Social.

However, the “final and conclusive” announcement offered no regulatory text, enforcement guidance, or legal authority, leaving details largely unclear – especially for China, which regularly engages in business dealing with Iran, often evading US sanctions to do so.

China remains the primary manufacturing hub for hardware components and consumer devices, including smartphones, laptops, tablets, wearables, servers, and networking equipment.

And, even when products are assembled outside China – for example, in Vietnam or India – they often rely on Chinese-made components such as printed circuit boards, displays, batteries, connectors, and cables.

What are the implications?

A major importer of Iranian oil and goods (as well as banned US technology), China is already paying steep 10% to 25% tariffs on exports to the US following Trump's year-long tariff wars with the communist nation.

A 25% Iran-linked tariff on Chinese exports would not only leave Chinese exporters reeling, but would also raise costs across the entire US tech ecosystem.

If implemented, Trump's layered tariffs also happen to coincide with rising hardware costs due to chip shortages, AI-driven demand, and supply chain strain.

Last month, Cybernews reported that electronics supply chains worldwide have been hit by a shortage of legacy memory chips in Q4, while rising semiconductor prices have begun to drag down smartphone shipments.

Apple smartphones are manufactured in China while Samsung now manufactures its smartphones in Vietnam, but uses Chinese sourced components.

Furthermore, Cybernews notes that RAM prices have also risen sharply due to the rapid expansion of AI computing and data centers.

With Chinese-made electronics already subject to tariffs near 25%, another 25% could push total rates to 50% or higher, triggering a trickle-down cost effect that would start with US tech importers and eventually reach US consumers.

As for US tech companies, an extra 25% tariff would not only raise prices but also reduce company profit margins, likely impacting stock prices and even slowing investment in new technology, start-ups, infrastructure expansion, and enterprise adoption.

major US tech companies that could feel the most impact include Apple, Dell, Samsung, HP, Cisco, Intel, Foxconn, and TSMC.

One potential bright spot, digital services, such as cloud platforms, SaaS products, and AI models, will most likely emerge unscathed from any Trump tariff fall-out.
