A Chinese company has ceased exporting equipment essential for lithium processing, reflecting the impact of proposed export controls by Beijing. Jiangsu Jiuwu Hi-Tech informed customers that, effective February 1, it would halt the export of sorbent filtration equipment, as per sources familiar with the matter and documents reviewed by Reuters.
China, recognized as the world’s leading producer of sorbents—materials used to extract lithium from brines and other solutions—has proposed restrictions on exporting certain battery and lithium technologies, including sorbents. Although these measures are currently proposals, Jiangsu’s decision indicates a shift in industry practices in anticipation of potential regulatory changes. If implemented, companies would be required to obtain government licenses for international sales.
An executive from another lithium extraction technology firm, who requested anonymity, disclosed that both Jiangsu and Sunresin New Materials, another prominent sorbent manufacturer, are in discussions with the government regarding the proposed regulations. Representatives from Jiangsu and Sunresin have not responded to inquiries. Notably, Sunresin’s chairman previously mentioned plans for overseas expansion, which included technology transfers to clients.
The Chinese Ministry of Commerce has yet to publicly address the proposal since its announcement. Industry insiders suggest that the mere prospect of these controls is already deterring exports to certain countries. A China-based international lawyer, serving clients in the clean energy sector, described the proposal’s effect as “chilling.” Reports indicate that ministry officials have engaged with several companies to discuss the proposal and, in one instance, cautioned against proceeding with a $1 billion export deal under negotiation. Additionally, financial institutions are reportedly seeking extra approvals before finalizing export financing for items listed in the proposal.
While the exact implications of the proposed export controls remain uncertain, the initiative underscores China’s strategic use of its dominance in the mining and processing of lithium and other critical minerals amid escalating trade tensions with the United States. For instance, China’s antimony export ban, announced in December, has already impacted the Western automotive market.
In the short term, disruptions in Chinese sorbent exports could affect Western oil producers’ plans to extract lithium, limiting their technological options. Companies like Exxon Mobil have considered utilizing Chinese processing equipment for planned lithium operations in Arkansas, according to sources familiar with the plans. Exxon declined to comment on the matter. Similarly, Koch Industries, a major investor in Arkansas-based lithium developer Standard Lithium, agreed in 2023 to use sorbents from China’s Xi’an Lanshen New Material Technology in its North American operations. A representative for Koch declined to comment.
Several Western sorbent producers believe they may capture market share, though they lack the extensive market experience of their Chinese counterparts, and their equipment has yet to reach commercial production. Brian Menell, CEO of TechMet—a company investing in Western mining firms and lithium equipment producers—emphasized the need for innovation without reliance on China, which has a significant head start and controls the market.
Francis Wedin, chairman of Vulcan Energy Resources, which has developed proprietary sorbent technology intended for use in Germany, noted a surge in interest from companies seeking to acquire or license their technology. While declining to name specific companies, Wedin mentioned that inquiries have come from major lithium firms in North and South America.
As the situation develops, stakeholders across the global lithium supply chain are closely monitoring the potential implications of China’s proposed export controls on the industry.
