U.S. President Donald Trump announced on Friday that a 25% tariff on imported iPhones will also extend to Samsung and other smartphone makers, while retaining a 50% levy on European Union goods until a trade deal is reached.

Tariff Details and Scope

• 25% on smartphones: Applies to all imported handsets, including those from Apple (NASDAQ:AAPL) and Samsung (KS:005930).

• 50% on EU goods: Continues in the absence of a bilateral agreement with the European Union.

The broader smartphone tariff threatens to raise consumer prices and squeeze margins for global vendors.

Valuation Impact on Tech Giants

With tariffs potentially cutting into overseas sales and profitability, investors will watch relative valuations closely. Apple and Samsung's forward price-to-earnings multiples—key indicators of how the market prices future earnings growth—can be benchmarked using the Ratios (TTM) API, revealing which manufacturer is trading at a premium amid tariff uncertainty.

Revenue Exposure to Smartphone Sales

Smartphone hardware represents a significant share of both companies' top lines. To quantify the impact, analysts can examine each firm's revenue mix via the Revenue Product Segmentation API, which breaks down sales by product category—highlighting how much of Apple's and Samsung's quarterly revenue hinges on device shipments.

These measures underscore rising trade tensions' immediate effects on consumer tech, with tariffs set to reshape pricing, margins, and market valuations for leading smartphone makers.
