Amazon (AMZN) sellers in China are preparing for a steep price increase or a strategic shift away from the US market as new tariffs make business increasingly unsustainable, Reuters reported Thursday, citing five sellers.

"For us and anyone else, you can't rely on the US market-that's quite clear," said seller Dave Fong, whose products range from schoolbags to Bluetooth speakers, told Reuters, noting a shift in investment toward regions like Europe, Canada, and Mexico.

Brian Miller, a Shenzhen-based Amazon seller for seven years, told Reuters that rising costs are forcing him to halt new product development.

Miller added that continuing to serve the US from China may no longer be viable, and manufacturing will most likely shift to countries such as Vietnam or Mexico.

Over 100,000 Amazon businesses are registered in Shenzhen alone, generating $35.3 billion in annual revenue, Reuters said, citing e-commerce services provider SmartScout.

Amazon did not immediately respond to MT Newswires' request for comment.
