The US said the duties were a response to China's state-sanctioned technology theft, subsidies and other "unfair practices" and allowed under 1970s-era trade rules.
But China said the taxes violated trade regulations because they were higher than US commitments and targeted only one country.
A panel of WTO experts agreed with those claims. It added that the US had not proved its case that the tariffs were justified on moral grounds because it did not show how the products affected by the duties had benefited from the unfair practices.
"The panel found, accordingly, that the US had not met its burden of demonstrating that the measures are provisionally justified," it said.Ambassador Robert Lighthizer, America's top trade negotiator, said the US "must be allowed to defend itself against unfair trade practices".
"This panel report confirms what the Trump Administration has been saying for four years: The WTO is completely inadequate to stop China's harmful technology practices," he said.
"Although the panel did not dispute the extensive evidence submitted by the US of intellectual property theft by China, its decision shows that the WTO provides no remedy for such misconduct."
