Output of Industrial Silicon and Polysilicon Fell MoM in October, Likely to Rebound in November

Published: Nov 05, 2021 14:34 (GMT+8)
SMM data showed that China’s polysilicon output stood at 40,400 mt in October, down 3% month on month, but up 17% year on year. China’s industrial silicon output stood at 270,000 mt in October, down 1.5% month on month, but up 15.6% year on year.

SHANGHAI, Nov 5 (SMM) – SMM data showed that China’s polysilicon output stood at 40,400 mt in October, down 3% month on month, but up 17% year on year.

The output fell on the month due to the power rationing in Jiangsu and Inner Mongolia. The production in Xinjiang, the largest silicon production area, was basically normal although the local plants received the production restriction notice.

Tongwei Sichuan commissioned a new capacity this week. Tongwei may put five newly built projects and technical transformation projects into production this year, which are expected to yield output in Q1 2022.

The national output of polysilicon is expected to rebound to around 42,000 mt in November.

SMM data showed that China’s industrial silicon output stood at 270,000 mt in October, down 1.5% month on month, but up 15.6% year on year.

The plants in Yunnan, Chongqing, and Inner Mongolia basically resumed the production from the power rationing. The operating rates in Gansu and Sichuan also rose after the maintenance. But Xinjiang reduced the production by over 10,000 mt due to the power rationing, leading to the slight decline in the total output.

Despite the power rationing, China’s monthly output of polysilicon stood at around 270,000 mt in September and October, which were little changed from that in August but lower than expected.

The national output of polysilicon is expected to increase to 290,000 mt in November, driven by the production recovery in Xinjiang and Fujian. The production in south-west China will be cut in the low-water period in December.

Aterian reports higher Rwanda 3T ore sales; trading margins remain estimates
[SMM Tantalum Flash] Aterian’s interim results, released on 30 September, show £1.341 million of Tantalum and other ore-sales revenue for the six months to 30 June 2026, up from £20,000 a year earlier. Gross profit was £522,000, while the group recorded a £568,000 pre-tax loss. Its Rwanda trading business deployed about US$2.18 million in working capital through joint-venture purchases. Management valued potential sales from those purchases at US$2.78 million, but cautioned that the notional valuation is not additional recognised revenue. The implied US$602,000 gross trading profit is also a management estimate, dependent on completed sales, assays, realised prices, costs and the joint venture’s profit allocation. Aterian said traceability inspections limited suppliers and volumes. It held £131,000 in cash at 30 June; its expectation of expanding trading volumes from the fourth quarter still depends on execution and funding.

Coherent launched PhotonLink, an integrated optics platform for AI infrastructure incorporating Indium Phosphide (InP) lasers, silicon photonics, detectors and optical modules. The company disclosed more than 10 CPO engagements, over 10 NPO engagements and more than five chip-to-chip connectivity projects, with anchor customers and long-term agreements secured for both CPO and NPO. Revenue is expected to begin ramping in Q4 2026. Coherent has shipped over 300 million InP lasers and is expanding its 6-inch InP manufacturing capacity to support the ramp. The customer pipeline provides a clearer commercial demand signal for InP devices and upstream materials, although additional capacity and indium consumption were not disclosed.

【Flash | Alleima Raises October Surcharges for Mo-Bearing Tube Grades】
Alleima raised tube alloy surcharges in Europe, Asia, Africa and Oceania from Oct 1. For hot-finished products, 316/316L rose from €5.26/kg (€5,260/t) to €5.33/kg (€5,330/t); High Mo from €5.74/kg (€5,740/t) to €5.81/kg (€5,810/t); SAF 2205 and SAF 2507 increased 2.26% and 1.95%; and 254 SMO rose 0.70%. The hot-finished energy surcharge more than doubled to €0.21/kg (€210/t). SMM analysis: Mo-bearing surcharges broadly rose, but the energy reset means the full increase cannot be attributed to molybdenum.
