# China's consultation on banning solar-technology exports closes Sunday as Indian manufacturers turn to Germany

Beijing's draft would prohibit exports of perovskite-tandem and thin-wafer manufacturing know-how and restrict several high-efficiency cell technologies, which threatens India's plan for 100 gigawatts of upstream solar capacity.

China's Ministry of Commerce and Ministry of Science and Technology have proposed adding 12 solar technologies to the country's catalogue of technologies that are banned or restricted from export, according to [Chinese financial coverage of Announcement No. 48](https://finance.eastmoney.com/a/202610213902009193.html). The public consultation ends on November 15. The draft would ban exports of manufacturing processes for perovskite and perovskite-silicon tandem cells, fluidized-bed polysilicon lines with annual capacity of at least 250,000 tonnes, and wafers 70 micrometers thick or thinner. It would restrict exports of polysilicon engineering for lines of 30,000 tonnes or more, wafer processes at 130 micrometers or below, and the high-efficiency cell designs known as TOPCon, xBC and HJT, [PV Tech reported](https://www.pv-tech.org/china-proposes-export-controls-on-polysilicon-wafers-and-other-pv-technologies/). The controls would also cover the core equipment that carries these technologies.

The Commerce Ministry gave two reasons. Solar technology now has uses in aerospace and defense, so exporting it may carry national-security risk. And some foreign governments require Chinese companies that build local factories to transfer core processes. The second reason matters most to buyers. Beijing is trying to keep its technological lead from being given away as a condition of overseas investment.

India is exposed. Mint reported that Indian manufacturers are [looking to German equipment and process suppliers](https://www.livemint.com/economy/indian-solar-manufacturers-look-to-germany-as-china-proposes-curbs-on-technology-exports-11794566204043.html) because the curbs could hurt India's plan to build a domestic supply chain, including 100 gigawatts of wafer, ingot and polysilicon capacity by the end of the decade. Most of India's planned upstream solar capacity depends on Chinese tools and know-how.

The solar list is part of a wider consultation on 40 technologies in AI, biomedicine and solar. Beijing has already applied the same approach to rare earths and battery technology.

## What this means

China is turning manufacturing know-how, not only raw materials, into an export-control tool. That raises the cost and slows the speed of every country trying to build solar supply chains outside China. Indian, Southeast Asian and US factory projects that planned to license Chinese processes or import Chinese production lines are the most exposed. German, Swiss and Japanese equipment makers gain pricing power. Chinese producers keep their cost advantage, and module buyers should expect prices from outside China to stay higher for longer. The market has followed China's rare-earth controls but has paid less attention to process know-how. The precedent is China's 2023 controls on gallium, germanium and graphite, which started as proposals and became permanent licensing regimes. The likelier outcome within months is a final rule close to the draft, applied through licenses that Beijing approves case by case and uses as leverage with each importing country. This depends on the consultation ending without major changes. It would be wrong if Beijing drops the restricted tier or grants a broad exemption to Chinese-owned factories abroad.

## What to watch

- Watch the final text after the November 15 deadline, especially whether the TOPCon restriction survives. TOPCon is the most widely used cell design, so keeping it would touch most new factories outside China.
- Watch Indian announcements of licensing deals with German or other non-Chinese equipment suppliers. They would show whether India's upstream plan can proceed on schedule without Chinese know-how.
- Watch whether Chinese companies building factories abroad get export licenses. Approval for some and refusal for others would show Beijing using the rule to reward or punish host countries.
