And now, hefty tariffs could make Apple's number one cash cow even more expensive.

The tech giant sold more than 230 million handsets last year to rake in an estimated $200 billion.

That is more than half of the company's total revenue.

The iPhone is essentially an expensive puzzle made with pieces sourced from all over the world.

And with Apple's suppliers coming from territories that were hard hit by Trump's tariffs, experts say the smartphone is about to get even more expensive.

Now take the iPhone 16 Pro, for example.

Its processor comes from Taiwan.

The rear camera is imported from Japan, which also supplies storage.

The battery and the main enclosure, that is made in China, while the display may be sourced from South Korea.

Our research from Tech Insights shows that Apple used to spend about $550 for all that hardware.

Now, factoring in 54% tariffs for China, where 9 in 10 iPhones are assembled, the cost rises to $850.

But with the Trump administration now proceeding with another 50% tariff, that could balloon further.

Now, Apple could offset some of the cost by instead importing its iPhones from India, where tariffs are significantly lower than China's.

The Wall Street Journal reports that Apple is already planning to source more phones from India as a short-term fix.

Rosenblatt Security's research shows that Apple would need to hike iPhone prices by 43% to help offset the cost.

This means that the iPhone 16 Pro, that would set you back $999 now, could soon be worth about $1,430.

Other research adds that Apple faces nearly $40 billion in tariff costs, and if the company absorbs all of that additional cost, it could take a 32% bite out of its operating profit.

Apple customers were reportedly rushing to U.S. stores to panic-buy devices over the weekend.

Bloomberg quoted Apple employees who say they have seen an increase in sales with customers asking about potential price hikes due to the tariffs.
