The proposal would have likely been consequential for the solar PV industry, which is plagued by allegations of forced labour in the production of polysilicon and other upstream components.
Major Chinese polysilicon producer Daqo New Energy saw both production and sales of polysilicon increase by around 50% in 2023 compared with 2022, whilst the dramatic drop in polysilicon prices slashed revenues from US$4.6 billion to US$2.3 billion over the same period.
Polysilicon imports to China have fallen to their lowest levels since 2011 as non-Chinese polysilicon producers have shipped greater volumes to Southeast Asia, according to a recent report from Bernreuter Research.
