U.S. steel producer Nucor is the "single biggest beneficiary" of the Trump administration's latest tariffs, CNBC's Jim Cramer said on Thursday.
The U.S. allies quickly struck back by announcing retaliatory measures.
"You can buy the stock of the one real corporate winner from this whole mess," he continued. "I suggest you take it before someone else does."
Nucor, the largest steel producer in the U..S., applauded the tariffs when they were first announced by Trump in March. At the time, Canada, Mexico and the EU were given temporary exemptions.
CEO John Ferriola told Cramer in March that since 1985, one-third of the U.S. steel industry has been wiped out. It has been caused, in part, by countries like China "dumping" steel, or keeping prices artificially low by flooding the market with supply.
"We're simply leveling the playing field, treating them the way that they have been treating us for over 30 years," Ferriola said.
Cramer said Nucor has done everything it can to lower the cost of its raw product and make itself more efficient. In fact, he called it the "most efficient steelmaker on Earth."
However, while the Chinese government subsidizes its steelmakers, the U.S. Congress would never authorize the same here, he noted.
"If the president wants to protect our steel industry, these tariffs are the best thing he can do," Cramer said.
Shares of Nucor barely moved on Thursday, closing 0.14 percent higher at $62.19, which the "Mad Money" host called "insane."
Nucor didn't immediately respond to CNBC's request for comment.
