The Petroleum and Explosives Safety Organization (PESO) is the regulatory authority responsible for ensuring the safe manufacture, storage, transportation, import, export, handling, and use of hazardous substances in India. Industries dealing with petroleum products, compressed gases, explosives, pressure vessels, gas cylinders, and other hazardous materials must comply with PESO regulations before commencing commercial operations.

PESO plays a critical role in protecting public safety, industrial infrastructure, and the environment by regulating activities involving flammable, explosive, and high-pressure materials. Obtaining a PESO Certificate is mandatory for various industries to ensure compliance with the applicable safety laws and technical standards prescribed by the Government of India.

The organization traces its origins back to the British era when it was established as the Department of Explosives to regulate explosive materials across the country. Over the decades, its responsibilities have expanded significantly, making it one of India’s most important regulatory bodies for hazardous substances and industrial safety.

Today, PESO oversees numerous sectors including petroleum, compressed gases, pressure vessels, LNG, CNG, Auto LPG, CBG, gas cylinders, cross-country pipelines, ammonium nitrate, flameproof electrical equipment, explosives, and many other hazardous products requiring statutory approval.

Businesses engaged in manufacturing, importing, storing, transporting, or handling regulated products must obtain the necessary PESO approvals before entering the Indian market. Non-compliance may result in penalties, suspension of operations, product seizure, or cancellation of licenses under the applicable laws.

At Bharati Global Compliances, we provide complete consultancy services for PESO Certification in India, assisting manufacturers, importers, exporters, EPC companies, OEMs, and industrial organizations with documentation, application filing, liaison with PESO authorities, technical compliance, factory approvals, and end-to-end licensing support.

What is PESO Certification?

PESO Certification is the statutory approval issued by the Petroleum and Explosives Safety Organization (PESO) for products, equipment, installations, and industrial facilities that deal with hazardous materials such as petroleum, compressed gases, explosives, pressure vessels, and other regulated substances.

Formerly known as the Chief Controller of Explosives (CCOE), PESO functions under the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry, Government of India.

The primary objective of PESO Certification is to ensure that hazardous products and industrial operations comply with the prescribed safety requirements before they are manufactured, imported, installed, transported, stored, or operated within India.

PESO Certification is particularly important for industries operating in sectors where even a minor safety lapse can lead to serious accidents involving fire, explosion, environmental damage, or loss of human life. Therefore, products covered under PESO regulations must undergo technical evaluation and satisfy the applicable standards before approval is granted.

For imported equipment, internationally recognized certifications such as ATEX and IECEx are often accepted by PESO, provided they meet the prescribed regulatory requirements. Where such certifications are unavailable or insufficient, additional product testing in India may be required before approval.
