Since the start of President Trump’s trade war, China has retaliated against US tariffs by raising tariffs on US goods. Less well known is that China has also been lowering rates for everyone else, putting US companies at an even greater disadvantage when trying to sell to China’s 1.4 billion consumers. Companies in the United States and elsewhere used to be on a level playing field, facing an average Chinese tariff of 8.0 percent. Now, there is a 14 percentage point difference between the average Chinese tariff US exporters face versus all other exporters. Some US goods are facing even wider differences in duties, like soybeans, farm and fish products, and certain manufacturing products.
