Impact of COVID-19 on Sodium Metabisulphite Market
Since the COVID-19 virus outbreak in December 2019, the disease spread to almost every country globally. The pandemic caused significant disruptions in the sodium metabisulphite market in 2020 due to supply chain interruptions, manufacturing slowdowns, and project delays in key sectors . However, demand from essential industries like food & beverage (for preservation), pharmaceuticals (for drug formulation), and water treatment remained resilient. The market rebounded strongly as governments worldwide prioritized food security, healthcare, and infrastructure investments in economic recovery packages .

Global Sodium Metabisulphite Market Segmentation

The market is segmented primarily by Grade and Application, catering to diverse needs across multiple industries .

By Grade:

• Industrial Grade: The largest segment, accounting for an estimated 55-60% of the market . It is extensively utilized in water treatment (dechlorination), textile processing (antichlor), pulp & paper (bleaching), mining (cyanide detoxification), and chemical synthesis. Its high reactivity and cost-effectiveness make it a preferred choice for these large-scale industrial processes .

• Food Grade: A significant and growing segment. It is widely used as a preservative, antioxidant, and sanitizing agent in the food and beverage industry. Key applications include preserving dried fruits and vegetables, preventing oxidation and microbial spoilage in wines and fruit juices, and as a bleaching agent in food processing . The Food Grade segment alone was valued at over USD 220 million in 2025 .

• Photo Grade: A niche, high-purity grade used in photographic developing and processing. Its demand has declined with the digitalization of photography but persists in specialized industrial and medical imaging applications .

• Pharma Grade: High-purity sodium metabisulphite used as an antioxidant, preservative, and reducing agent in pharmaceutical formulations. It is critical for stabilizing active ingredients in injectable drugs, ophthalmic solutions, and other sterile products .

By Application:
