What Hoshine Silicon does
Hoshine Silicon Industry Co., Ltd. (合盛硅业股份有限公司, SSE: 603260) is a vertically integrated silicon-based materials manufacturer founded in 2005 by Ningbo Hesheng Group and listed on the Shanghai Stock Exchange main board in 2017. Headquartered in Cixi, Ningbo, the company operates digital manufacturing bases across five Chinese provinces — Xinjiang, Zhejiang, Sichuan, Yunnan, and Heilongjiang — alongside R&D centers in Shanghai and Hainan. Chairman Luo Liguo (罗立国) has led the company since founding.
The company operates eight business segments: Energy, Industrial Silicon, Organosilicon, Photovoltaic, New Materials, Semiconductors (silicon carbide), Carbon Materials, and Energy Storage. Core upstream products include metallurgical-grade industrial silicon, silicon powder, fine silicon powder, graphite electrodes, and chlorosilane monomers (M1/M2/M3/MH), which feed midstream siloxane intermediates (DMC, D3-D5). Downstream the company produces high-temperature and room-temperature vulcanized silicone rubber (HTV/RTV), silicone sealants, silicone oils, and silicon dioxide. Its photovoltaic line spans N-type monocrystalline wafers, TOPCon bifacial cells, high-efficiency N-type modules, encapsulant films (EVA/EPE/POE), aluminum frames, photovoltaic glass, and solder ribbons, supplemented by a third-generation semiconductor silicon carbide (SiC) materials franchise. Industrial silicon and organosilicon monomer production capacities have ranked #1 globally for consecutive years, and SiC/PV R&D strength is positioned in the industry's first tier.
The business model is a B2B industrial-manufacturer model with quotation-based pricing, no publicly disclosed price list, and dedicated direct sales divisions for each of photovoltaic, industrial silicon, and organosilicon product lines. Customers span aerospace & defense, electronic communications, healthcare & medical, automotive manufacturing, solar photovoltaic, and construction & architecture; no individual customer is publicly named in the input. Distribution combines direct enterprise sales with the Silicon Cloud (硅云在线) e-commerce platform at siliconcloud.cn for silicon-based new materials. Marketing relies on vertical industry exhibitions (WINDOOR, SNEC, China Industrial Silicon Industry Chain Annual Conference), government and CSR recognition (MIIT 9th-batch Manufacturing Single Champion, Fortune China 500, Hurun China 500, Global New Energy Enterprise 500 No. 154, China Petroleum and Chemical Enterprise Top 500), and Shanghai Stock Exchange investor relations disclosures. Recognition includes a National Intellectual Property Advantage Enterprise designation (2023) and approval of a National Postdoctoral Research Workstation (March 2025).
