China’s prefabricated building exports rose to $4.3 billion in 2025 from $1.7 billion in 2020, with the United States, Southeast Asia, Australia and Western Europe among the main markets. Hebei Shengtai Integrating Housing shifted from container-style quarantine units and temporary worker accommodation to more sophisticated homes for overseas tourism and vacation-property buyers after China’s property downturn damaged domestic demand. The broader export expansion reflects China’s ability to use large-scale production, tightly integrated supply chains and fast delivery to compete abroad, even as tariffs and geopolitical tensions persist. Domestic competition is also driving a severe price squeeze: Sun Guangqing said his factory’s double-wing expandable homes now sell for below 20,000 yuan, leaving only 1,000-2,000 yuan in profit per unit. He expects more than one-third of the industry to close in coming years.
