The theory behind tariffs is that by raising the price of an imported good, they give a stronger footing in the market; eventually, the domestic producer may no longer need the tariff to be competitive. Imposing a tariff means we’ve decided that a particular industry is important enough that it needs this kind of support — or as some might call it, protection — even if it means higher prices for a while.
The problem with across-the-board tariffs of the kind Trump proposes is that they create higher prices even for goods that are not being produced domestically and probably never will be. If tariffs raise the price of a six-pack of tube socks at Target from $9.99 to $14.99, it won’t mean we’ll start making tube socks in America again. It just means you’ll pay more. The same is often true for domestic industries that use foreign parts in their manufacturing: If no one is producing those parts domestically, their costs will unavoidably rise.
The U.S. imported over $3 trillion worth of goods in 2023, and $426 billion from China alone, so Trump’s proposed tariffs would represent hundreds of billions of dollars of increased costs. That’s before we account for the inevitable retaliatory tariffs, which is what we saw in Trump’s first term: He imposed tariffs on China, which responded by choking off its imports of American agricultural goods. In the end, the revenue collected from Trump’s tariffs went almost entirely to bailing out farmers whose export income disappeared.
The past almost-four years under Joe Biden have seen a series of back-and-forth moves in which new tariffs were announced, other tariffs were increased, exemptions were removed and reinstated. For instance, this May Biden increased the tariff on Chinese electric vehicles to over 100% while adding tariffs on certain EV batteries. But some of the provisions didn’t take effect right away, and only certain products were affected, so the net economic impact was minimal. And there’s been nothing like an across-the-board tariff.
It’s reasonable to criticize Biden’s tariff policies related to climate. But his administration was trying to navigate a dilemma, serving two goals at once: reducing emissions and promoting the development of domestic clean energy technology. Those goals are not always in alignment, at least in the short run, which we can see in the conflict within the solar industry. Companies that sell and install solar equipment benefit from cheap Chinese imports and therefore oppose tariffs, while domestic manufacturers want the tariffs to continue so they can be more competitive. The administration has attempted to accommodate both interests with a combination of subsidies to manufacturers and tariffs on certain kinds of imports — with exemptions peppered here and there. It’s been a difficult balancing act.
Then there are electric vehicles. The world’s largest EV manufacturer is Chinese company BYD, but if you haven’t seen any of their cars on the road, it’s because existing tariffs make it virtually impossible to import Chinese EVs to the United States. That will continue to be the case under Trump, and it would have been the case if Kamala Harris had been elected.
On one hand, it’s important for America to have the strongest possible green industries to insulate us from future supply shocks and create as many jobs-of-the-future as possible. On the other hand, that isn’t necessarily the fastest route to emissions reductions. In a world where we’ve eliminated all tariffs on EVs, the U.S. market would be flooded with inexpensive, high-quality Chinese EVs. That would dramatically accelerate adoption, which would be good for the climate.
But that would also deal a crushing blow to the American car industry, which is why neither party will allow it. What may happen, though, is that Chinese car companies may build factories in Mexico, or even here in the U.S., just as many European and Japanese companies have, so that their cars wouldn’t be subject to tariffs. That will take time.
Of course, whatever happens will depend on Trump following through with his tariff promise. We’ve seen before how he declares victory even when he only does part of what he promised, which could happen here. Once he begins implementing his tariffs, his administration will be immediately besieged by a thousand industries demanding exemptions, carve-outs, and delays in the tariffs that affect them. Many will have powerful advocates — members of Congress, big donors, and large groups of constituents — behind them. It’s easy to imagine how “across-the-board” tariffs could, in practice, turn into Swiss cheese.
There’s no way to know yet which parts of the energy transition will be in the cheese, and which parts will be in the holes. The manufacturers can say that helping them will stick it to China; the installers may not get as friendly an audience with Trump and his team. And the EV tariffs certainly aren’t going anywhere.
There’s a great deal of uncertainty, but one thing is clear: This is a fight that will continue for the entirety of Trump’s term, and beyond.
