China Initiates Antidumping Duty Investigation into Analog Chips (Chips) from the United States
On September 13, 2025, China’s Ministry of Commerce initiated an antidumping (AD) investigation into imports of analog chips (chips) from the United States. If an affirmative decision is issued in this investigation, duties may be imposed on subject U.S. exports.
What is an antidumping duty (AD) investigation?
An AD investigation assesses whether foreign goods imported into a country are being sold at less than fair value (below prices or costs) in the domestic market (i.e., being dumped) and whether this is causing or threatening to cause injury to the domestic industry.
