Market Analysis

According to data from SunSirs' commodity analysis system, the market for sodium bicarbonate is currently undergoing a weak consolidation phase, though shipments from manufacturers remain steady. Prices in the Henan region are holding steady, with ex-factory rates ranging from 1,100 to 1,200 RMB/ton; in the Shandong region, ex-factory prices range from 1,150 to 1,250 RMB/ton. As downstream industries are largely purchasing on an "as-needed" basis, the market is expected to continue consolidating in the near term.

Raw Materials: According to monitoring data from SunSirs, soda ash prices trended downward in May. The average market price for light soda ash stood at 1,222 RMB/ton at the beginning of the month, falling to approximately 1,196 RMB/ton by month's end—a decline of 2.13% for the month, and a year-on-year decrease of 13.71% compared to the same period last year.

Market outlook:

Analysts at SunSirs observe that the price of sodium bicarbonate has recently been undergoing a weak, consolidating trend. Regarding upstream raw materials, the soda ash market generally remained stable throughout April. Downstream sectors—including pharmaceuticals, textiles, and food—have recently been purchasing primarily on an "as-needed" basis, reflecting only moderate demand. Amidst this interplay between supply and demand, the overall forecast suggests that sodium bicarbonate prices will likely continue to fluctuate in the near term, with specific price movements ultimately dependent on demand within the downstream market.
