Two major Chinese lithium producers, Tianqi Lithium Corp. and Ganfeng Lithium Group Co., are calling for higher standards from third-party data providers and greater consistency in methodology. The commentary came after a jump in inventories reported by one third-party firm sparked heated debate in the industry and spurred a 14% slump over three days in the most active lithium carbonate contracts. The producers argue that unreliable data creates market volatility and undermines investor confidence.

They are urging regulators and industry bodies to establish clearer guidelines for data collection and reporting to prevent similar disruptions. The incident highlights the growing influence of third-party analytics on commodity markets and the need for transparency in an increasingly data-driven trading environment.
