SAN JOSE, Calif. – That shiny new iPhone may say "assembled in China" on the back, but its origins are scattered around the world: wafers from Taiwan, modem chips and batteries from South Korea, displays from Japan, components from Europe and raw materials from Africa, Asia, Europe and the U.S.
Now that complicated supply chain may put Apple — the world's most valuable company — in the bull's-eye as President Donald Trump and congressional Republicans consider sweeping import tariffs or a comprehensive border tax on incoming products, components and raw materials.
But while Apple has been singled out by Trump before, the administration's actions would affect a who's who of Silicon Valley's big-name tech companies — which could see sales, revenue and access to global talent take a hit from new fees and the trade wars that could follow.
"It's a real mess," said Marcus Noland, executive vice president at the Peterson Institute for International Economics, a Washington, D.C., think tank that supports free trade.
Only two months into the Trump administration, it's difficult to discern how an import tariff or border tax might take shape, but the president has said he wants to punish U.S. companies that make goods overseas to sell back home. Imposing new costs on imports would encourage domestic manufacturing and create jobs, Trump has argued.
While campaigning, Trump mentioned a 45 percent import tariff on goods from China and 35 percent on imports from Mexico. More recent reports suggested the Trump transition team was looking at a 10 percent fee. House Republicans, meanwhile, have proposed a 20 percent "border adjustment tax" covering all imports from all countries.
The list of firms with the most to lose from an aggressive new tariff or tax regime includes the valley's biggest names: Google, Tesla, Oracle, HP, Cisco, Intel, Seagate, Western Digital, Nvidia, Marvell Semiconductor and more.
Consumers also will inevitably see increased costs from import tariffs or a tax passed on to them, according to experts. "You and I are going to pay for it," said Georgia Tech professor John Vande Vate.
