On January 4th, the quoted price for industrial-grade sodium metabisulfite (content 96.5%) in the Hunan market was 2,200 yuan per ton, an increase of 50 yuan per ton. The price of sodium metabisulfite continues to rise due to rising raw material costs and increased demand. PriceSeek's analysis of sodium metabisulfite shows a bullish-bearish score of +1.5. The report indicates that the spot price of industrial-grade sodium metabisulfite in the Hunan market has increased by 50 yuan per ton to 2,200 yuan per ton, primarily driven by the dual factors of rising raw material costs and increased market demand. The increase in raw material costs (such as the rising prices of upstream raw materials like sulfur) has raised production costs, while sustained strong demand has intensified the tight supply-demand situation in the market, suggesting a potential continued upward trend in prices in the short term. Considering the current performance of the spot market, this represents a strong positive signal, hence a score of +1.5 is assigned, reflecting the supportive effect on commodity prices.
