PESO licence is a mandatory regulatory approval required for industries dealing with hazardous materials such as petroleum, explosives, compressed gases, and chemicals. It is not just a formality but a safety and legal requirement governed under multiple central laws.
In India, industrial safety compliance is becoming stricter. With increasing enforcement by CPCB and SPCB authorities, any unit operating without proper approvals is exposed to immediate closure and legal action.
Businesses today must understand that PESO approval directly impacts:
A delay of even 30 days in approval can impact production planning, supply chain commitments, and revenue generation.
PESO, or Petroleum and Explosives Safety Organisation, is the central authority responsible for regulating hazardous substances in India. It ensures that storage, handling, and manufacturing processes comply with safety standards.
The organisation operates through regional offices across India and conducts technical scrutiny and physical inspections before granting approvals.
Industries covered under PESO include:
In practical terms, PESO acts as a gatekeeper. Without its approval, no unit can legally store or process hazardous materials.
Key functions of PESO include:
PESO licensing is governed by a combination of acts and rules that define technical and safety standards. These laws operate together, and compliance must be ensured across all applicable frameworks.
The primary regulations include:
Each of these regulations applies to a specific category of hazardous material and defines licensing conditions.
For example, petroleum storage is governed by capacity thresholds, while pressure vessels are governed by design and safety standards.
Non-compliance is treated as a serious violation. Under Section 15 of the Environment Protection Act, 1986:
PESO licences are categorized depending on the nature of operations. Each category has different approval requirements and technical standards.
This licence is required for facilities involved in manufacturing hazardous products.
It applies to:
Manufacturing licences require detailed scrutiny of plant design, process flow, and safety systems. Approval must be obtained before installation and commissioning.
Storage licences are issued based on the quantity and classification of materials.
Typical examples include:
The approval depends on:
Even small storage facilities exceeding defined thresholds require PESO approval.
Importers and exporters dealing with hazardous materials must obtain PESO clearance.
This applies to:
Without PESO approval, customs clearance can be delayed or rejected.
Transport approvals are required for:
These approvals ensure that transport systems meet safety standards during movement.
| Regulation | Requirement | Deadline | Applicable To | Risk |
|---|---|---|---|---|
| Explosives Rules, 2008 | Licence before manufacturing/storage | Before operations | Explosives units | Shutdown |
| Petroleum Rules, 2002 | Storage licence based on capacity | Pre-installation | Oil storage | Fire hazard |
| Gas Cylinders Rules, 2016 | Approval for filling/storage | Before operation | Gas plants | Explosion risk |
| SMPV Rules, 2016 | Vessel design approval | Before commissioning | Pressure vessels | Seizure |
This table highlights that all approvals must be obtained before operations begin. Post-installation approvals are not permitted.
The PESO approval process involves multiple stages, each requiring technical accuracy and documentation completeness.
The first stage involves preparing a compliant layout based on safety standards.
The layout must consider:
Incorrect layout design accounts for nearly 40–50% of application rejections.
The application is submitted with detailed documentation.
Typical submission includes:
Incomplete applications lead to immediate delays or queries.
PESO evaluates the application for:
This stage usually takes 15 to 30 days depending on complexity.
Physical inspection is conducted to verify:
Any mismatch results in rejection or rework.
Once all conditions are satisfied:
| Step | Authority | Timeline | Documents | Risk |
|---|---|---|---|---|
| Planning | Applicant | 7–15 days | Layout | Rejection |
| Filing | PESO | Day 0 | Forms | Delay |
| Scrutiny | PESO | 15–30 days | Technical data | Query |
| Inspection | PESO | 15–30 days | Site readiness | Failure |
| Approval | PESO | 30–90 days | Final compliance | Hold |
Most projects experience delays due to incorrect documentation or non-compliant site conditions.
A complete documentation set is essential for approval.
Mandatory documents include:
Missing even one critical document can delay approval by 30 to 60 days.
PESO licence is not a standalone approval. It is part of a broader compliance ecosystem.
It must align with:
In many cases, PESO approval is dependent on environmental clearance. Lack of coordination between approvals is one of the biggest reasons for project delays.
Failure to comply with PESO regulations can have serious consequences.
A petroleum unit fails inspection due to incorrect tank spacing.
A manufacturing plant submits partial documents.
A chemical unit starts operations without PESO approval.
PESO compliance should be integrated at the project planning stage itself.
Early planning ensures:
In contrast, delayed compliance can increase project cost by 10–20% due to redesign and penalties.
PESO licence is a critical requirement for industries handling hazardous materials in India. It is a technical, inspection-driven approval that must be planned carefully.
Businesses must approach PESO compliance with a structured strategy that includes:
Early compliance not only reduces risk but also ensures faster project execution and operational stability.

Any business involved in storage, manufacturing, or handling of petroleum, explosives, or gases requires a PESO licence.
The approval process usually takes between 30 to 90 days.
No, operating without a PESO licence is illegal and can lead to shutdown and penalties.
The licence is typically valid for 1 to 5 years depending on the category.
