What Sichuan Yongxiang Co., Ltd. does

Sichuan Yongxiang Co., Ltd. (四川永祥股份有限公司) is a wholly-owned subsidiary of Tongwei Co., Ltd. (600438.SH) and serves as Tongwei's dedicated manufacturing platform for high-purity polysilicon and silicon materials. The company produces electronic-grade and solar-grade high-purity polysilicon, solar silicon wafers, and industrial silicon, operating four production bases across Leshan (Sichuan), Baotou (Inner Mongolia), Baoshan (Yunnan), and Guangyuan (Sichuan). With 900,000 tons of annual high-purity polysilicon capacity, Sichuan Yongxiang has ranked #1 globally in polysilicon market share and shipment volume since 2021 (InfoLink) and has held #1 across ten key operational metrics for three consecutive years.

The company's core technology centers on chemical-engineering-based polysilicon production integrated with new energy applications via a circular economy industrial chain that combines upstream industrial silicon, midstream polysilicon, downstream silicon wafers, and solar power generation (56 PV stations, 5.1+ GW grid-connected). Notable technical achievements include Yunnan Tongwei Phase I completing pile-driving-to-production in 355 days (industry record) and Yunnan Tongwei Phase II (200,000 tons) becoming the world's largest single-unit capacity project at successful commissioning on May 1, 2024.

Sichuan Yongxiang operates a B2B direct sales model supplying polysilicon to downstream solar PV cell and module manufacturers, with dedicated sales contacts per product line (polysilicon, cell, module) and geography (domestic and overseas). Revenue is generated through hardware sales of polysilicon and silicon materials under quote-based pricing that is not publicly disclosed. The customer base consists of solar photovoltaic manufacturers using the materials for cell production, module assembly, and ultimately solar power generation. Originally founded as Yongxiang Resin, the company transitioned into high-purity polysilicon production and now anchors Tongwei's upstream silicon materials value chain.

Emerging players

• REC Silicon: REC Silicon operates fluidized-bed reactor (FBR) polysilicon plants in the United States and Norway, focused on solar-grade material using a Siemens alternative process. It is a niche technology peer whose fortunes depend on demand for non-Xinjiang, non-Siemens silicon.

Regional players

• Tokuyama Corporation: Tokuyama (TYO: 4043), a Japanese chemical company, produces high-purity polysilicon for semiconductor and solar applications from its Yamaguchi facility. It is a regional peer primarily serving Asian electronic-grade feedstock demand.

Direct peers

• Wacker Chemie AG: Wacker Chemie (FRA: WCH) operates the Burghausen and Charleston polysilicon plants, producing both solar- and semiconductor-grade material. It is the largest Western polysilicon supplier and the most direct international competitor for premium electronic-grade feed.
• Daqo New Energy: Daqo New Energy (NYSE: DQ) is a pure-play high-purity polysilicon manufacturer with operations in Xinjiang. Like Yongxiang, Daqo sells solar-grade polysilicon to wafer and cell makers and competes directly on per-ton cost leadership.
• East Hope Group: East Hope Group is a privately held Chinese conglomerate that entered the polysilicon business at scale from 2021 onward and is now a top-tier Chinese supplier. It competes with Yongxiang on capacity, cost, and downstream integration.
• Xinte Energy: Xinte Energy (HKEX: 1799), a subsidiary of TBEA, is a major polysilicon producer running large Xinjiang-based facilities. It supplies solar-grade and electronic-grade polysilicon into the same downstream Chinese cell and module manufacturers as Yongxiang.
• GCL Technology Holdings: GCL Technology (HKEX: 3800) is China's largest polysilicon producer by capacity and Yongxiang's most direct head-to-head competitor. Both firms supply solar- and electronic-grade polysilicon to Chinese cell and module manufacturers and compete on scale, cost, and technology.
• Asian Silicon (Asia Silicon Co., Ltd.): Asia Silicon is a Chinese polysilicon producer based in Qinghai with both electronic- and solar-grade output. It competes with Yongxiang in the same domestic tier-1 customer pool.
• OCI Company: OCI (KRX: 010060) has historically been one of the top global polysilicon producers with plants in South Korea and Malaysia. Despite restructuring and partial asset sales, it remains a peer in commodity-grade solar polysilicon pricing.

Broad incumbents

• Tongwei Co., Ltd. Tongwei Co., Ltd. (SHA: 600438) is the publicly listed parent of Sichuan Yongxiang and the broader group's solar platform. It operates solar cell (150GW), module (90GW), and downstream PV power station (5.1GW) businesses alongside Yongxiang's polysilicon.
