UN Mark IIP Certificate for Class 3 Flammable Liquids
The UN Mark IIP (Indian Institute of Packaging) Certificate, commonly referred to as the UN Certificate, is required for packaging hazardous products such as flammable liquids classified under Class 3. Flammable liquids under class 3 are defined as liquids with a closed-cup flash point below 60°C, the lower the flash point, the greater the fire risk during transport. Class 3 Flammable Liquids are classified by flash point: Flash point <-18°C (Packing Group I — extreme fire risk, e.g. diethyl ether, carbon disulfide); Flash point -18°C to 23°C (Packing Group II — high risk, e.g. acetone, ethanol, gasoline); Flash point >23°C to ≤60°C (Packing Group III — medium risk, e.g. diesel, kerosene, turpentine). The flash point determines the packing group, and which IIP packaging type is required. The UN Certification serves as proof that these products meet the necessary safety standards required for transportation by air or sea in United Nations member countries. Any firm dealing with dangerous goods must adhere to UN-certified packaging requirements to prevent mishandling, leakage, or accidents during transportation.
The UN IIP Certificate is issued by the Indian Institute of Packaging (IIP), a government-recognized body under the Ministry of Commerce & Industry. This organization conducts performance tests on packaging materials to determine whether they meet the relevant safety standards of various countries. The UN Certification applies to flammable liquid substances such as petroleum-based fuels, ethanol, and chemical reagents. Various tests, including impact tests, pressure tests, and chemical compatibility tests, are conducted to check the durability of packaging under different conditions. Obtaining UN Certification is mandatory for transporting flammable liquid containers and tankers.
Below is a detailed process for obtaining a UN Mark for Class 3 Flammable Liquids, including the required documents and measurement parameters for existing regulations. Any company involved in the use and transport of industrial chemicals, fuel, or solvents must obtain a UN IIP Certificate, which can be granted by complying with IIP testing standards. UN Certification ensures legal compliance, adherence to safety standards, and the efficient transportation of dangerous goods across borders.

What is UN Mark IIP Certificate for Flammable Liquids?
The Indian Institute of Packaging (IIP) requires packaging used in the transportation of Class 3 hazardous liquids, including gasoline, ethanol, acetone, and other flammable solvents, to have a UN Mark IIP Certificate for Flammable Liquids. This certification guarantees that the packaging satisfies UN safety regulations needed for both domestic and international shipping.
For those who handle hazardous liquids, such as manufacturers, exporters, and logistics companies, certification is crucial. It attests to the fact that the packaging has passed performance tests such as pressure resistance, drop resistance, and leakproof testing. The certification complies with the DGCA requirements in India, the ICAO/IATA regulations for air travel, and the IMDG Code for maritime travel. Most Class 3 liquids have Stowage Code A (on or under deck away from heat sources). Packing Group I liquids (highest flash point risk) must be stowed on deck only. Class 3 must be segregated from: UN Mark Classes 1 explosives, 4.1 (flammable solids), 5.1 (oxidizers), and open flames.
The validity of the UN Mark IIP Certificate typically ranges from 9 to 18 months, depending on whether the manufacturer is ISO certified. Obtaining this certificate is crucial to ensure safe, legal, and efficient shipment of flammable liquids.
Benefits of IIP Certification for Class 3 Flammable Liquids

- Cost Savings: UN approved packages help to avoid fines, legal consequences, and rejected shipments, certification lowers general expenses that are related to compliance violations, damaged goods, and potential danger.
- Competitive Advantage: Obtaining an IIP UN Mark certificate allows businesses to become more competitive and find more customers and partners due to compliance with the requirements for operating at a high level of safety and quality.
UN Numbers for Class 3 Flammable Liquids
UN numbers are 4-digit identification codes used to classify explosive materials and articles for transport and handling. Key Class 3 UN numbers are:
- UN1203 (gasoline/petrol, PG II)
- UN1202 (diesel fuel, PG III)
- UN1170 (ethanol solution >24%, PG II)
- UN1090 (acetone, PG II)
- UN1230 (methanol, PG II)
- UN1294 (toluene, PG II)
- UN1263 (paint/varnish, PG I/II/III)
Note: Liquids transported at or above their flash point temperature are classified as Class 3 flammable liquids even if their normal flash point exceeds 60°C. This applies to some heated industrial processes and heavy oils transported at elevated temperatures.
India-Specific Compliance for Class 3 Flammable Liquids
Petroleum Act 1934 and Petroleum Rules 2002 govern storage and transport of petroleum-based flammable liquids (gasoline, diesel, kerosene, LPG) within India. The Petroleum and Explosives Safety Organization (PESO) issues licenses for petroleum storage and transport. IIP UN Mark Certification for packaging is required for international transport. Both PESO authorization (if applicable) and IIP certification must be obtained for compliant export of petroleum products.
India is among the world's top exporters of petroleum products (HS Chapter 27). Refined petroleum products including diesel, petrol, jet fuel (aviation turbine fuel), and lubricating oils are Class 3 Dangerous Goods. Professional Utilities assists in obtaining Class 3 IIP UN Mark certification for petroleum exporters across India.
