SMM News, June 25 – According to an official announcement from Jinguan Copper, a subsidiary of Tongling Nonferrous Metals Group Co., Ltd., the company began publicly selling 32 metric tons of crude selenium yesterday, though the reserve price was not disclosed. The deadline for bid submissions is June 25, 2025. Market observers noted that the one-day bidding window suggests the seller has strong confidence in offloading this batch of crude selenium. Recently, many selenium producers have ramped up tenders for selling selenium products. Some manufacturers have increased shipments ahead of mid-year, putting downward pressure on selenium prices. The rise in crude selenium supply from producers has sustained market oversupply, keeping prices weak across selenium products—including selenium dioxide—with a clear downward trend. Some analysts also highlighted that the outcome of Tongling Nonferrous Metals Group’s tender will be crucial, as it may indicate the price resilience of crude selenium. SMM will continue to monitor developments.
