Walmart — the world's largest retailer — is now issuing a warning to customers that they may be paying more for the same products if President-elect Donald Trump makes good on his promise to impose new tariffs on imports.

Our model is everyday low prices,” CFO John David Rainey said. “But there probably will be cases where prices will go up for consumers.”

As an increasing number of retailers make plans to prepare for tariffs, the idea of them becomes more looming. Here are eight companies that have been outspoken about tariff risks.

Trump promised voters tariffs are a panacea for the economy, but Walmart finance chief John David Rainey warned they will be inflationary for customers.

The discounter's comments are the latest warning from retail leaders about the potential impact of the tariffs.

Walmart has expressed concerns about the potential economic consequences of the tariffs proposed by President-elect Donald Trump.

Higher tariffs on Chinese exports will backfire, just increasing prices paid by consumers, while China can manage to weather the effects of such "external shocks," a senior Commerce Ministry official said Friday in Beijing.

For the second largest economy, China, a big source of concern is tariffs against Chinese products. During the campaign trail, Trump had stated that he would impose at least 60% tariffs on Chinese imports and 20% tariffs on imports from all other countries.

ECP Asset Management Portfolio Manager Andrew Dale says there will be “upwards pressure” on pricing with Donald Trump’s tariff plans.
