The UN Mark IIP (Indian Institute of Packaging) Certificate, also known as the UN Certificate, is a crucial requirement for shipping hazardous gases classified under Class 2. This category includes compressed gases, liquefied gases, dissolved gases, and refrigerated liquefied gases. The UN certification ensures that these products comply with transportation safety regulations for air and sea across UN (United Nations) member countries. It is mandatory for companies handling dangerous goods to meet UN-certified packaging standards to prevent accidents, leakage, or damage during transportation.
The UN IIP Certificate is issued by the Indian Institute of Packaging, an entity operating under the Department of Commerce and Trade. Some of the gases regulated under UN Packaging standards include oxygen, nitrogen, carbon dioxide, propane, butane, and acetylene. To evaluate the endurance of packaging materials, the Indian Institute of Packaging (IIP) conducts impact tests, pressure tests, and chemical compatibility tests to ensure their durability under various conditions. The UN certification is required for transporting compressed gas cylinders, cryogenic liquids, aerosols, and gas cartridges. This helps to reduce transportation risks and ensures that the goods are safely packaged according to international standards.
Below is a detailed overview of securing a UN Mark for Class 2 hazardous gases, including the necessary documentation, testing parameters, and compliance with relevant regulations. Obtaining UN Packaging certification ensures legal compliance, enhances safety standards, and facilitates the smooth shipment of dangerous goods.
