What project owners need to know.
China's commerce and science ministries proposed on 16 October 2026 to add 40 technologies to the Catalogue of Technologies Prohibited and Restricted from Export, 12 of them in photovoltaics across polysilicon, wafer and cell manufacturing, together with the key equipment that carries them. It is a draft open for comment until 15 November 2026; for India, whose ingot and wafer lines rely largely on Chinese equipment and know-how, it raises the stakes on equipment sourcing and on localising consumables.
What China has proposed
On 16 October 2026 China's Ministry of Commerce (MOFCOM) and Ministry of Science and Technology published a draft revision of the Catalogue of Technologies Prohibited and Restricted from Export, Announcement 2026 No. 48. Xinhua reported that it covers 40 technologies across artificial intelligence, biomedicine and photovoltaics, of which 12 are PV technologies spanning polysilicon, wafer and cell manufacturing, and that the key equipment carrying those technologies is also covered.
Reuters reported that some thin-wafer technologies, perovskite and tandem cells and fluidised-bed polysilicon would fall in the prohibited category, while TOPCon, heterojunction and back-contact cell technologies would need an export licence. MOFCOM has said the revision is not aimed at any particular country. Comments are open until 15 November 2026; the item-by-item annex and any technical thresholds should be read on the MOFCOM site before drawing conclusions.
- Announcement 2026 No. 48 (MOFCOM and MOST), published 16 October 2026
- 40 technologies in total, 12 of them photovoltaic
- Covers polysilicon, wafer and cell technologies and the key equipment that carries them
- Draft only: comments until 15 November 2026
This has been tried before
A similar idea surfaced on 30 December 2022, when the same ministries published a draft that named wafer, black-silicon and ingot-casting technologies, pv magazine reported. When the final catalogue was issued on 21 December 2023 as Announcement 2023 No. 57, the large-size wafer and black-silicon items were left out, according to law firm Hogan Lovells' review.
In July 2025 China did finalise restrictions in an adjacent sector, adding battery cathode, lithium processing and gallium technologies to the catalogue. The pattern is that drafts can change materially before they are final, but that clean-energy manufacturing know-how is now firmly on the list of what China considers strategic.
Why India's ingot and wafer plans are exposed
India's ingot and wafer build-out has been planned largely around Chinese equipment. TaiyangNews reported in 2023 that China has more or less a monopoly on ingot and wafer machinery, and that some Indian manufacturers said they could buy from the US, Europe or Japan instead, at higher cost. In July 2026 Reuters, citing anonymous industry sources, reported that China had already curbed exports of solar manufacturing technology, equipment and technical support to India; that report concerned cells and modules.
The exposure is not only to machines. Crystal growth depends on process recipes, commissioning support and spare parts. If equipment and the technology it embodies need licences, timelines for projects racing to qualify before ALMM List-III applies on 1 June 2028 could be affected. How much depends on what the final list contains and how licences are administered, which is not yet known.
- Pullers, wire saws and hot-zone design
- Commissioning, process recipes and technical support
- Spare parts and upgrades over the plant's life
What Indian developers are reportedly doing
Responses so far are attributed, not settled. Large groups have said they can source from non-Chinese suppliers if needed. Domestic equipment development is at an early stage: SolarQuarter reported in January 2026 that Raana Semiconductors raised funding to develop Indian-made Czochralski ingot pullers. Neither route replaces an established supply chain quickly, which is why the final shape of China's list matters.
Where domestic materials fit
Whatever the origin of the puller, every Czochralski ingot is grown in a fused-quartz crucible that is consumed in use, from high-purity quartz, under argon, inside a graphite hot zone. These consumables are bought continuously for the life of the plant, so localising them reduces exposure to any single country's trade rules even when the equipment itself is imported.
That makes consumables one of the faster levers available to India: qualified quartz crucibles, high-purity quartz sand, graphite parts and argon supply can be developed in parallel with equipment decisions, rather than after them.
- Quartz crucibles and high-purity quartz sand
- Graphite hot-zone parts
- Argon and vacuum systems
What to watch
Three things will decide the impact. First, the final MOFCOM catalogue and its annex: which wafer and equipment items survive, and whether they are prohibited or licensed. Second, how licensing works in practice for equipment already contracted. Third, India's own timelines: ALMM List-III from 1 June 2028 and the materials pillar of India Semiconductor Mission 2.0, which affect how fast domestic alternatives are funded.
How JRST supports this requirement
JRST works on the parts of the ingot chain that India can localise now: high-purity quartz sand processing, crucible supply coordination and Maharashtra's first silicon-ingot line in Nagpur. We help project teams plan consumables and equipment sourcing together. This guide summarises public reporting on a draft measure as of the date shown. The final Chinese list may differ; confirm against the official MOFCOM announcement and current Indian notices before making a procurement or investment decision.

Has China banned solar wafer technology exports?
Not yet. On 16 October 2026 China published a draft revision of its export-control catalogue that includes 12 PV technologies across polysilicon, wafer and cell manufacturing. Comments are open until 15 November 2026, and the final list may differ.
Did China restrict wafer technology exports in 2023?
A December 2022 draft named wafer, black-silicon and ingot-casting technologies, but the final catalogue issued on 21 December 2023 left the large-size wafer and black-silicon items out.
Does this affect Indian ingot makers' equipment?
Potentially. The 2026 draft also covers the key equipment that carries the listed technologies, and Indian ingot and wafer lines rely largely on Chinese machinery. The effect depends on the final list and how licences are granted.
What can India localise fastest?
Consumables such as quartz crucibles, high-purity quartz sand, graphite hot-zone parts and argon supply, which every ingot line buys continuously regardless of where its pullers come from.
Is the measure aimed at India?
MOFCOM has said the revision is not aimed at any particular country.
