If both the manufacturing and supply chain of an iPhone were completely moved to the United States, the cost of the device would increase even more than if only the manufacturing were done on U.S. soil.
Currently, the production cost of an iPhone (like the base iPhone 16, with a retail price of $799) is estimated to be around $400-$500, according to breakdowns from firms like Counterpoint Research or IHS Markit, thanks to the efficiency of the Asian supply chain and low labor costs. Moving everything to the U.S. would imply:
Labor: Wages in the U.S. are significantly higher than in China. For example, an assembly worker in China might earn $3-$5 per hour, while in the U.S., the federal minimum wage is $7.25, although in many states it exceeds $15 per hour, not counting benefits.
Supply chain: Components like displays (from Samsung or BOE in Asia) or chips (manufactured by TSMC in Taiwan) would need to be produced locally or imported with potential tariffs. Establishing semiconductor or battery factories in the U.S., like those TSMC has begun building in Arizona, costs billions and takes years, raising initial costs.
Scale and efficiency: Foxconn's infrastructure in China is highly optimized to produce millions of units quickly. Replicating that in the U.S. would require time and massive investment.
If Apple passed all that increase onto the consumer (which doesn't always happen, as they might absorb some of the cost to maintain competitiveness), the retail price could be between $1,500 and $3,500 for a base model, depending on factors like government subsidies, long-term economies of scale, and profit margins.
