Chinese importers noted a sudden and unannounced reduction to zero of tariffs on U.S. imports of certain semiconductor and integrated circuit products, a sign that Beijing is feeling more pressure from President Donald Trump‘s trade war than it acknowledges.

It comes after the Chinese foreign ministry denied Trump’s comments that the U.S. is “actively” engaged in talks with China on trade. Trump has also softened his tone on China in recent days, soothing some fears of a prolonged conflict.

Chen Shaoling, a manager at Zhengnenliang Supply Chain, told CNN she learned on April 24 that tariffs on eight kinds of integrated circuits, covering most semiconductors except for memory chips, were now zero.

China had hit the U.S. with a 125 percent retaliatory tariff after Trump imposed a 125 percent levy on most Chinese goods, plus another 20 percent related to its role in the fentanyl trade. Section 301 tariffs also pile on top of those.

“We only found out after we filed the declaration—without doing that, we wouldn’t have known,” Chen said. “The news is now spreading like wildfire.”

Another company in China, Shenzhen HJET Supply Chain, posted on social media that it had “great news” about the tariffs after receiving a new notice from Chinese customs.

It said eight tariff codes related to semiconductors and integrated circuits “are exempt from tariffs imposed on the United States” which meant they had “been reduced to zero”.

Similar reports were documented by the Chinese business magazine Caijing.
