Export of Sodium Metabisulfite

Sodium metabisulfite is a non-organic chemical compound with a wide range of industrial applications. This inorganic compound, which is formed from the combination of sodium, hydrogen, and oxygen, is also known as sodium pyrosulfite. Sodium metabisulfite is an ionic compound containing a cation and is produced in industrial and food-grade varieties. It is a white powdery substance with a very unpleasant and pungent odor that readily dissolves in water. This ionic compound is used in most industries as a disinfectant and antioxidant and has many customers. Therefore, the export of sodium metabisulfite is of special importance.

The application of sodium metabisulfite in food grade

Sodium metabisulfite is used in the food industry as a preservative and anti-spoilage agent, particularly in shrimp, fruit juice, vinegar and lemon juice, seafood, dried fruits, and more. Therefore, the export of sodium metabisulfite has a good market in the food industry. Although the World Health Organization has approved the use of this product in food grade in general, excessive use of it in food can lead to liver problems.

Storage method of sodium metabisulfite

Due to the toxic nature of this substance, it must be stored in a protective container. If the insulation is weak, there is a possibility of combining sodium metabisulfite with oxygen and releasing toxic gas, sulfur dioxide. The storage temperature is another factor to consider when storing this substance because if the temperature and humidity of the storage is higher than 25 degrees Celsius and 45%, respectively, it can cause the solution to change. Although this substance has non-flammable properties, sodium metabisulfite begins to decompose and release toxic gases and hazardous oxides of sodium and sulfur at a temperature of 150 degrees Celsius. Also, the combination of these toxic gases with water and their entry into the environment has many risks. Additionally, to prevent corrosion, this combination must be kept away from metals. If you are preparing sodium metabisulfite for export, be sure to follow safety precautions during storage and transportation.

Packaging method of sodium metabisulfite

Sodium metabisulfite is usually sold in powder form in 20-kilogram bags, and in the case of bulk orders, it is sold in side bags. The packaging for exporting sodium metabisulfite is standard and is determined based on the volume purchased.

Safety precautions when working with sodium metabisulfite

This inorganic chemical compound is classified as a hazardous chemical because exposure to it can cause problems such as asthma, respiratory diseases, headaches, irregular heartbeat, skin burning and itching, redness and tearing of the eyes, digestive system irritation, nausea, vomiting, and diarrhea. For this reason, you should be careful when working with it and follow the following precautions:


1- Always store sodium metabisulfite in an environment away from acids and chemicals.


2- note that this substance must be stored in an appropriate warehouse (dry and cool environment).


3- Use impermeable gloves, safety glasses, and protective clothing when working with sodium metabisulfite.


4- Never allow sodium metabisulfite to penetrate into groundwater, surface water, or sewage systems. Because its release can cause the death of fish and disrupt the ecosystem.


5- If this substance comes into contact with your body, quickly change your clothes and go to a medical center for treatment.


6- If sodium metabisulfite leaks onto the ground, wash the area with water immediately.



When buying and exporting sodium metabisulfite, pay attention to all safety precautions and follow them.
