A PESO License is a mandatory approval issued by the Petroleum and Explosives Safety Organisation (PESO) for any business that manufactures, stores, imports, transports, fills, tests, or otherwise handles petroleum products, explosives, gas cylinders, compressed gases, SMPV pressure vessels, or hazardous chemicals in India. PESO functions under the Chief Controller of Explosives and operates within the Department for Promotion of Industry and Internal Trade (DPIIT). The license covers document scrutiny, a possible technical interview, and in many cases a factory audit, and it carries a fixed validity period that must be renewed before expiry to avoid penalties or suspension. Foreign manufacturers typically apply through an Authorized Indian Representative (AIR).
Businesses that work with flammable, explosive, or pressurised substances operate in one of the most tightly regulated corners of Indian industry — and for good reason. A single lapse in storage, fabrication, or testing can put workers, communities, and the environment at direct risk. That is the backdrop against which the PESO license exists.
Whether you run a fuel storage facility, manufacture or fill gas cylinders, fabricate pressure vessels, or import hazardous equipment into India, a valid PESO license is the legal precondition for operating. This guide walks through what the license actually covers, who needs it, the SMPV rules that govern pressure vessels specifically, the documents you'll need, the approval steps, and what fees, validity, and renewal look like in practice.

What Is PESO and What Does the License Cover?
The Petroleum and Explosives Safety Organisation (PESO) is India's regulatory authority for the safe handling of petroleum, explosives, and pressurised or compressed substances. It is headed by the Chief Controller of Explosives and functions as an autonomous body under the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry.
A PESO License is the formal authorisation confirming that a facility, its equipment, and its operating processes meet the safety standards set out under the applicable petroleum and explosives legislation. Operating in a regulated activity without this approval is treated as an offence under Indian law, carrying penalties that extend to suspension or shutdown of operations.
Storage, handling, and distribution of petroleum and fuel products fall directly within PESO's regulatory scope.
Manufacture, storage, and handling of explosives and ammonium nitrate are subject to strict PESO oversight.
Manufacturing, filling, and testing of gas cylinders and compressed gas equipment requires PESO approval.
Static and mobile pressure vessels, along with hazardous chemical handling, are governed under dedicated PESO rules.
Who Needs a PESO License
PESO licensing applies broadly across the value chain — from manufacturing through storage, testing, and import. Businesses commonly falling within scope include:
Petroleum storage installations and fuel stations require a valid PESO license to operate.
Units manufacturing, filling, or testing gas cylinders fall directly within the mandatory scope.
Fabrication shops producing static and mobile pressure vessels are subject to SMPV rule compliance.
Companies importing pressure equipment or hazardous materials into India require PESO clearance through an authorised route.
Both Indian manufacturers and foreign manufacturers — the latter typically operating through an Authorized Indian Representative (AIR) — fall within these compliance obligations. Degassing, purging, and testing-station operators are also commonly brought within scope depending on the specific activity.
SMPV Unfired Rules and Pressure Vessel Compliance
Static and Mobile Pressure Vessels (SMPV) store gases, liquids, or vapours at pressures above atmospheric level — and because that stored pressure is itself a hazard, SMPV Unfired Rules impose some of the strictest requirements under the entire PESO framework.
Design and operating requirements exist specifically to prevent pressure failure, explosions, or gas leaks.
Rules address keeping stored substances free from external contamination throughout their handling.
Design, fabrication, inspection, testing, maintenance, and operating conditions are all held to defined standards.
Pressure vessels typically remain subject to periodic inspection well after initial approval, not just at the licensing stage.
BIS FMCS Certification for Foreign Manufacturers

Document Checklist for PESO License
PESO applications are document-heavy, and incomplete or inconsistent paperwork is one of the most common causes of delay or rejection. A typical submission includes:
- Completed PESO application form — Filed for the specific license category applicable to the activity.
- Business and plant licensing documents — Confirming the legal standing of the manufacturer and the facility.
- Authorized Indian Representative contract — Typically covering a minimum multi-year term, for foreign manufacturer applications.
- Technical competence evidence for the AIR — Demonstrating the representative's capability to support the application.
- Global organisation chart — Mapping the manufacturer's corporate and manufacturing structure.
- ATEX or IECEx certificates — Where applicable to the product's hazardous-area rating.
- Recent test reports — Generally required to be within a defined recency window.
- Quality Assurance Report — Documenting the manufacturer's quality control practices.
- Manufacturer profile and production/testing equipment list — Covering machinery and test instrumentation.
- ISO certification — Supporting evidence of a certified quality management system.
- Facility video and commercial history — Including recent sales data and an Indian customer list where relevant.
- Hazardous area installation details — Describing how the product or facility interacts with classified hazardous zones.
PESO License Application Process
Assemble the technical, commercial, and compliance documentation required for the applicable license category.
File the completed application with PESO along with the prescribed fee and supporting documents.
PESO officials examine the submission against the applicable rules to confirm completeness and compliance.
Technical personnel may be called before the PESO Interview Board to assess knowledge of design, testing, inspection, and safety standards.
For categories such as pressure vessels, PESO may inspect the facility to verify safety practices on the ground.
On successful review, PESO issues the license, including approval of the Authorized Indian Representative where applicable.
Indian Manufacturer vs. Foreign Manufacturer Route
The core review steps — documentation, scrutiny, possible interview, possible audit, and license grant — apply regardless of where the manufacturer is based. The practical difference lies in who submits the application and what additional supporting structure is required.
- Application filed directly by the Indian manufacturer
- Facility and equipment documentation for the domestic site
- Direct coordination with PESO for scrutiny, interview, and audit
- Standard license issuance in the manufacturer's name
- Application routed through an Authorized Indian Representative
- Long-term AIR contract and technical competence proof required
- Global organisation chart and overseas facility documentation submitted
- License approval covers both the manufacturer and the AIR
Fees, Timeline, Validity & Renewal
Vary by hazardous material type, license category, and whether inspection or audit is required.
Generally ranges from a few weeks to several months depending on documentation quality and inspection needs.
Fixed period specified in the approval letter for the granted license.
Must be initiated before expiry with updated compliance documents and the applicable renewal fee.
Risks of Operating Without a Valid License
Carrying out a regulated hazardous-material activity without a valid PESO license is unlawful under Indian law.
Non-compliance can trigger penalties, suspension of operations, or forced shutdown until approval is obtained.
Missing a renewal deadline can lapse an existing license, interrupting operations that depend on continuous approval.
Beyond legal risk, unlicensed handling of hazardous material puts workers and communities at direct safety risk and damages trust with regulators and clients.
