China's sodium pyroantimonate production assessment in October is expected to decrease by approximately 12.24% MoM [SMM data]

According to SMM's assessment, China's primary grade sodium pyroantimonate production in October 2025 is estimated to decrease by approximately 12.24% MoM from the previous month. After experiencing a significant rebound in September, China's primary grade sodium pyroantimonate production saw another considerable decline in October, leading many market participants to lament that the expected peak demand season in October has not materialized. Some producers indicated that the production drop at the beginning of Q4 is largely related to the current reduction in orders. Market participants stated that recent frequent market rumors regarding production rectifications and policy requirements in the PV glass sector, such as accelerating the phase-out of outdated capacity, may have somewhat affected sodium pyroantimonate orders. In terms of detailed data, among SMM's 13 survey subjects, four producers were either shut down or in the debugging stage in October, only one sodium pyroantimonate producer saw some production growth, and three producers experienced production declines. Consequently, China's overall primary grade sodium pyroantimonate production in October decreased significantly. Market participants expect that the likelihood of a continued decline in national sodium pyroantimonate production in November compared to October is relatively small; with the approach of year-end, it remains uncertain whether the market will emerge from the off-season, and the possibility of production remaining flat is greater.

Note: Since July 2023, SMM has been publishing its assessed national sodium pyroantimonate production. Benefiting from SMM's high coverage rate in the antimony industry, the total number of sodium pyroantimonate producers surveyed by SMM is 13, distributed across six provinces in China, with a total sample capacity exceeding 86,000 mt and a total capacity coverage rate as high as 99%.
