For Malaysian factories that make light-emitting diodes, it is an opportunity. For American makers of outboard boat motors, it is a threat. For the biggest sellers of flat-screen televisions, it is a nuisance.

The emerging trade war between the United States and China has prompted predictions of severe economic and geopolitical disruption. But for any given industry, the impact of tariffs depends on the microeconomics of its products: How much does demand change when its prices rise? Are substitutes readily available? How much extra productive capacity is there around the world, and how long would it take to get new manufacturing facilities up and running?

“How this will play out is idiosyncratic to any given product and unique to each supply chain,” said Daniel Rosen, partner at the economic research firm Rhodium Group. “Nobody can honestly claim high confidence that they understand what the overall impact will be. You may as well project the weather on a Tuesday afternoon a year from now.”

The United States imposed its first wave of tariffs over the spring, and each of the 1,102 goods that may be affected will end up with its own list of winners and losers. To see how this may unfold, it’s helpful to examine the different trade patterns for those goods, along with some of the thousands of comment letters that companies and industry groups have submitted to the U.S. Trade Representative. And executives and other experts have their own sense of exactly how supply chains might be rerouted and prices might swing for particular goods.
