Chipmakers with US-based manufacturing slump on higher tariff exposure

Shares of chipmakers with U.S.-based manufacturing facilities fall after Chinese Semiconductor Industry Association's notice on "retaliatory" tariffs makes cos liable for higher levies

Analog chipmakers Texas Instruments TXN.O down 8.2% to $143.87 and Analog Devices ADI.O falls 4.3% to $171.0

Automotive semiconductor firm Onsemi ON.O down 4.7% at $33.25, PC and server chip giant Intel INTC.O down 7.3% at $18.42

CSIA exempts U.S. chipmakers that outsource manufacturing from China's retaliatory tariffs

The CSIA rules the country of origin is where the wafer fabrication plant is located, making TI, with its U.S.-based fabs, liable for tariff rates of 84% or higher, according to EETop, an information platform and forum for Chinese chipmakers

The move will benefit chip firms like Qualcomm QCOM.O and AMD AMD.O that outsource to TSMC, shielding them from the tariff scuffle between the two largest economies

AMD and AI chipmaker Nvidia NVDA.O up 3.3% and 1.4% respectively, QCOM down 1.9%
