The Trump administration is working on an executive order that would initiate investigations into "unfair" product dumping from foreign companies — an action that could lead to tariffs on a wide range of products.

These plans are very fluid, and internal disagreements remain about how aggressive this order should be. Here's what I've learned from administration sources:

Steel and aluminum will be targeted.

Other products, including household appliances, could be targeted as well.

If the investigations result in new import duties — as some senior Trump officials believe should happen — it could make some consumer goods more expensive and could hurt the stock prices of American companies that rely on cheap steel imports. A good number of American manufacturing companies, however, could benefit from this hit to their low-cost competitors.

A White House official said this investigation is part of Trump's effort to protect American jobs and end unfair trade practices like dumping and foreign government subsidization.

"The administration will use the results of that investigation to determine the best path forward, which could potentially include everything from no action at all to the levying of supplemental duties," the White House official said. "But whichever action we take will be informed by the results of the investigation and not by predetermined conclusions."
