Citing multiple sources, Nikkei reports that the five companies have been scouting various other Asian countries as possible new homes for electronics production.
This is the latest chapter in the tech cold war that has snowballed substantially amid President Donald Trump's trade war with China.
Nikkei reported last month that Apple was seriously considering moving 15% to 30% of its iPhone production out of China, an early sign US companies wanted to reduce their exposure to the country.
Google, Amazon, and Microsoft
Game consoles and smart speakers are the primary concern for the Silicon Valley giants Google, Amazon, and Microsoft — along with Sony and Nintendo.
Shutterstock Amazon is looking at moving production of its e-readers and Echo smart speakers to Vietnam, Nikkei said. Microsoft is weighing up Thailand and Indonesia, presumably for production of the Xbox as well as its lesser-known Cortana speaker.
Nikkei gave no details about where Google might consider moving production of its Google Home smart speakers.
US tariffs pose an existential threat to video game consoles. Last week, Sony, Microsoft, and Nintendo wrote a joint letter to the US government asking that game consoles be left off any tariff lists because of the "disproportionate harm" tariffs would cause to US consumers and business.
Dell and HP
For Dell and HP, notebook computers are the main area where the companies are said to be looking to move production. The two companies shipped a combined 70 million notebook devices last year, according to Nikkei, most of which were made in China.
Dell is already trialing notebook production in Taiwan, Vietnam, and the Philippines, Nikkei said, citing two people familiar with the plan.
Two sources also told Nikkei that HP was looking to shift 20% to 30% of production out of the country and was considering Thailand and Taiwan as alternatives. One source said the changes could begin as early as late July but were still liable to change.
Google, Amazon, and Dell were not immediately available for comment when contacted by Business Insider. Microsoft and HP declined to comment on the report, although an HP spokesman said in a statement: "HP shares industry concerns that broad-based tariffs harm consumers by increasing the cost of electronics. We are actively monitoring the situation and will continue to work with government officials to advocate for the best interests of customers, partners and consumers."
