The cost might rise for Barbie dolls, Hot Wheels cars and other Mattel products due to the Trump administration's handling of tariffs on goods produced in China, Mexico and Canada.

While the cost of nostalgia may not be calculable, the cost of tariffs is, and because of them, several popular toys, including the iconic Barbie doll, may soon get more expensive at the store.

Mattel shares surged 14% in premarket trading on Wednesday after the Hot Wheels maker provided an upbeat annual profit forecast and hinted at stabilizing toy demand, despite tariff-related uncertainty.

Shares of Mattel Inc. jumped after hours on Tuesday after the toy maker forecast an adjusted per-share profit for this year that came in above analysts’ expectations, as it takes actions — including potential changes to its prices — to offset a fresh round of tariffs from President Donald Trump.
