LONGi said in a financial filing that the contract would last three years and would entail the purchase of around 64,638MT for its subsidiaries that produce monocrystalline silicon ingots and wafers locate in Yinchuan, Baoshan, Lijang and Ningxia, China.

The polysilicon contract between LONGi subsidiaries is with OCI in Korea and its Malaysian operations, acquired in 2017 from Japan’s Tokuyama.

Recently, PV Tech reported that LONGi was tripling ingot/wafer capacity through 2020. The new strategic plan includes taking ingot/wafer capacity to 28GW by the end of 2018 and 36GW by the end of 2019. LONGi also said that the plan was to achieve 45GW by the end of 2020.

OCI has around 52,000MT of polysilicon capacity in South Korea and its average product mix in 2017 for mono-quality polysilicon was said to be only around 35%.

Polysilicon production at its facility in Malaysia, recently acquired from Tokuyama is being expanded from a nameplate capacity of 13,800MT to 16,000MT per annum by the end of 2018, through upgrades and debottlenecking and engineering process improvements and could be expanded to 20,000MT to 25,000MT based on market demand.
