In China, the average Sodium Alginate price was ~USD 19,187/MT (FOB) in the last month of H1'26. India recorded an average price of ~USD 19,254/MT (CIF) during June. During H1 2026, sodium alginate prices remained broadly stable to firm as adequate brown-seaweed availability limited raw-material pressure while higher processing costs supported producer offers. China had reasonable kelp availability during the harvesting season, with one major Zhejiang production area reporting annual output of more than 2,000 MT, reducing the risk of severe feedstock shortages. However, industrial input costs strengthened entering Q2, increasing expenses associated with extraction, purification, drying and transportation amid the disruptions in major sea routes, resulting in higher fuel prices. Demand from food thickeners, pharmaceutical formulations, textile printing and specialty industrial applications remained steady, while differences in viscosity and purity kept pricing differentiated by grade. Import-dependent markets also faced additional freight and handling costs, supporting higher landed values.
Analyst Insight
According to Procurement Resource, sodium alginate prices are expected to remain broadly stable to firm as steady downstream demand and processing costs offset adequate seaweed availability.

During the second half of 2025, sodium alginate prices generally maintained a firm tone as demand from food processing, pharmaceuticals, cosmetics, textiles, and specialty applications remained consistent. North American markets continued to receive support from import dependence and stable consumption, while European prices were underpinned by steady pharmaceutical and food-sector requirements alongside production, energy, and logistics costs. In Asia Pacific, China remained an important production and export hub, with improving seaweed cultivation and processing capacity helping maintain raw-material availability. However, higher processing expenses and continued demand from downstream manufacturers limited the scope for substantial price reductions. Buyers generally maintained disciplined procurement, balancing regular consumption requirements against inventory considerations. The availability of seaweed from major Asian cultivation regions provided a degree of supply stability and reduced the likelihood of a pronounced shortage. Overall, sodium alginate prices remained firm through H2 2025, with stable downstream demand and production costs supporting the market, while improving raw-material availability helped prevent excessive price escalation.
Sodium alginate (NaC6H7O6) is a 1,4-D-mannuronic (M) and L-guluronic (G) acid-based linear polysaccharide derivative of alginic acid. A component of marine brown algae's cell walls, sodium alginate includes between 30 and 60 percent alginic acid. Alginac acid is transformed into sodium alginate, which makes it water soluble and facilitates extraction. Only two bacterial genera, Pseudomonas and Azotobacter, can produce bacterial alginates, which are employed for adhering to surfaces and protecting cells from the environment by creating biofilms.

In this method, chopped wet seaweed is treated with diluted formalin to create sodium alginate solution. To separate the sodium alginate solution from the seaweed residue, sodium carbonate is next added. Alginate acid is created by mixing sodium alginate solution with hydrochloric acid, followed by the removal of water. Alginic acid is combined with sodium carbonate and alcohol to create sodium alginate. The powdered form is eventually achieved when it has been dried and ground.
