China’s solar technology export-control draft: what starts now and what remains proposed
A draft would prohibit or license transfers of 12 photovoltaic manufacturing technologies. The bans are not final, but an interim export-registration rule is already in force.
China has opened consultation on a technology-export catalogue that would tighten controls on 12 photovoltaic manufacturing technologies. The proposed bans and licence requirements are not yet final; a separate interim registration procedure for listed technology exports took effect on October 16.
Two policy steps are moving on different clocks
The Ministry of Commerce published both a draft technology-export catalogue and an interim registration announcement on October 16. The catalogue is open for comment until November 15, so its proposed prohibitions and licence requirements are not final rules. The registration measure is different: exporters involved in listed technology transfers must already file transaction information while the catalogue review continues.
Which solar technologies would be prohibited
Reuters and PV Magazine identify proposed prohibitions covering selected perovskite and tandem-cell manufacturing know-how, ultra-thin silicon-wafer processes and large-scale fluidized-bed polysilicon technology. A prohibition would stop the covered technology from being transferred abroad rather than merely require an export licence. The exact thresholds and technical definitions in the catalogue therefore matter more than broad labels such as “solar equipment.”
Which processes would require a licence
The draft would move other photovoltaic production technologies into a restricted category, meaning an export licence would be required. The list includes advanced crystalline-silicon cell processes such as TOPCon, heterojunction and back-contact families, alongside related manufacturing know-how. A restricted classification is not an automatic ban, but it adds review, documentation and timing risk to transfers.
What the proposal does not directly ban
The catalogue targets technology exports: know-how, process packages, equipment-linked expertise, overseas licensing and similar transfers. It does not directly prohibit exports of finished solar cells or modules. The official interim notice also reaches less obvious transactions, including intellectual-property transfers, overseas licences, changes in ownership or control and continuing projects, so companies cannot assess exposure from customs codes alone.
What manufacturers and partners should watch next
Companies should map each cross-border project to the catalogue’s technical descriptions, separate proposed controls from the registration obligation already in force, and preserve records for ongoing transfers. The November 15 consultation deadline is the next fixed milestone. After that, the final catalogue may change, and any prohibited or restricted classification should be read from the final text rather than assumed from the draft.
