Chempricehub analysis of sodium metabisulfite, long-short score: 1.5. The spot price of sodium metabisulfite rose by 100 yuan per ton to 2,400 yuan per ton, driven by the high and volatile costs of raw materials like sulfur and soda ash, reflecting tight supply and demand and positive market sentiment, which is favorable for spot prices. Sulfur, long-short score: 0.5. Sulfur prices remained high and volatile. As a key raw material for sodium metabisulfite, cost support has strengthened, but the impact on sulfur's own spot price is neutral to slightly positive, as there are no significant signals of price increases or decreases.
