The price of sodium metabisulfite continues to rise due to rising raw material costs and increased demand. Chempricehub analysis of sodium metabisulfite, Bull-Bear Score: +1. The quoted price for food-grade sodium metabisulfite (content 96.5%) in the Hunan market rose by 300 yuan per ton to 4,200 yuan per ton, primarily driven by rising raw material costs and increased market demand, leading to a continuous upward trend in spot prices. This reflects tightening supply and demand, with rising raw material prices on the supply side pushing up production costs, and consumption growth on the demand side supporting firm prices. It is expected that spot prices may further strengthen in the short term. The score is +1 (generally positive), as the price increase is significant and the trend is clear, but it does not constitute an extreme event, hence it does not reach the level of a major positive factor.
