China Proposes Export Curbs on Advanced Solar, AI and Biotech
China's Ministry of Commerce and the Ministry of Science and Technology have unveiled a comprehensive draft regulatory framework proposing strict export controls across more than forty advanced technologies. Designated as Announcement No. 48, the sweeping directive establishes targeted prohibitions across the three strategic sectors of photovoltaics, artificial intelligence algorithms, and biotechnology. The regulatory proposal partitions the targeted technologies into two distinct enforcement categories, recommending a total foreign export prohibition for 14 cutting-edge industrial processes. An additional 26 critical industrial capabilities have been placed under a restrictive licensing framework requiring rigorous government evaluation prior to international transfer. A formal 30-day public comment window commenced on October 16 and will run through November 15, 2026, allowing domestic and global stakeholders to submit regulatory feedback.
Similar export restrictions were announced by China in December 2024 for gallium, germanium, and antimony, followed by April 2025 controls on seven medium and heavy rare earths along with processing equipment, according to ExamineChina.
Renewable Energy Controls and Photovoltaic Safeguards
Regulators identified 12 specific photovoltaic manufacturing technologies for statutory control, encompassing polysilicon production and advanced wafer manufacturing processes. Proposed complete export bans explicitly target next-generation perovskite manufacturing technologies and tandem solar-cell module fabrication systems. Controlled technologies on the restricted licensing tier include high-capacity polysilicon engineering systems utilized to fabricate commercial solar cells. Commerce ministry officials emphasized that standard mass-market solar modules and finished consumer photovoltaic hardware will remain freely exportable to international buyers.
In 2024, the Chinese polysilicon industry reached a share of 93.5 percent in global output and 95 percent in solar-grade polysilicon, according to Bernreuter Research.
Artificial Intelligence Software and Dual-Use Restrictions
Within the draft catalogue, artificial intelligence accounts for the largest regulatory category, comprising 23 of the 40 proposed technology listings. Targeted software algorithms restrict autonomous code synthesis engines, automated harmful code generation systems, and self-mutating cyber tools. Regulators stressed that technologies that have previously entered the public domain through open-source software distributions or published research papers remain exempt from the export catalogue.
In October 2026, SMM Analysis reported that temporary pre-export registration takes effect from the announcement date and requires exporters to register covered technology transfers and specified equipment before export, including ongoing transfers that have started but remain incomplete.
Geopolitical Supply Chain Impact and Consultation Roadmap
Trade analysts noted that the rules could complicate joint-venture agreements and overseas equipment purchases by Indian and international solar cell manufacturers. Following the conclusion of the public consultation period on November 15, Chinese regulatory ministries will evaluate industry comments before issuing finalized enforcement orders.
