Not correct. Once again, tariffs only affect imported goods. If you buy an iPhone built in China (assuming you import to the US) you’re going to pay a tariff on the device.
If you buy a phone built in America, with Chinese processors, you only pay tariff on the processor.
“Trolling” = discussing facts? You are the one who doesn’t understand. It’s very simple: US tariffs do not apply to US products.
