When a Pune-based chemical manufacturer tried exporting a small batch of industrial solvents, the shipment was held back at the port. The reason? Missing PESO approval for one of the storage tanks.
A simple compliance miss turned into six weeks of operational downtime, vendor penalties, and sleepless nights.
This scenario plays out often across India’s energy, chemical, and manufacturing sectors. Whether you’re importing a petroleum-based product, setting up a fuel storage tank, or installing explosion-proof machinery, PESO certification is the safety license that keeps your business running — and legally protected.
At its core, PESO approval is not just paperwork — it’s proof that your equipment, plant, or product is safe to operate, store, and transport.
The Petroleum and Explosives Safety Organization (PESO), under the Department for Promotion of Industry and Internal Trade (DPIIT), is India’s statutory authority ensuring safety in:
The certification ensures your product complies with national standards under:
PESO approval is mandatory before you manufacture, import, install, or operate any product that handles flammable, pressurized, or explosive materials.
PESO certification applies to a wide range of businesses, including:
| Category | Covered Entities | Examples |
|---|---|---|
| Explosives & Pyrotechnics | Manufacturers, traders, and transporters of explosives | Fireworks, detonators, mining explosives |
| Petroleum & Solvents | Refineries, distributors, and end users storing petroleum | Diesel storage, lube plants, kerosene dealers |
| Gas Storage & Distribution | Industrial, medical, or commercial gas units | LPG bottling, CNG stations, cryogenic tank suppliers |
| Explosion-proof Electrical Equipment | Manufacturers and importers of Ex machinery | Pumps, control panels, motors, junction boxes |
| Testing & Cylinder Facilities | Testing stations, fabrication plants, cylinder manufacturers | Gas cylinder manufacturers, valve fabricators |
If your business involves hazardous substances, compressed gases, or petroleum derivatives, PESO certification is not optional — it’s the legal entry ticket to operate.
While the checklist varies slightly by product category, a complete file typically includes:
Determine which category your product falls under — Explosives Rules, Petroleum Rules, SMPV Rules, or Gas Cylinder Rules.
Green Permits assists in mapping your products to the correct regulatory framework.
Compile detailed technical drawings, safety reports, and testing data.
For explosion-proof (Ex) products, ensure design compliance with IEC 60079 or equivalent standards.
The PESO online portal accepts all document uploads and payments. Digital submission has replaced most manual filings.
Within 30 working days, PESO officers may raise clarifications. Applicants must respond promptly online to avoid rejection.
Depending on product type, PESO may conduct on-site or virtual verification. For Ex equipment, approvals are often document-based; for petroleum storage, physical inspection is mandatory.
Once approved, PESO issues a digital certificate — valid for 3 to 5 years. Renewal is to be applied for 60 days before expiry.
| Application Type | Typical Government Fee | Estimated Timeframe | Remarks |
|---|---|---|---|
| Ex Equipment (Electrical Apparatus) | ₹15,000–₹50,000 per model | 8–12 weeks | Inspection may be waived |
| Petroleum Storage Licence | ₹25,000–₹1,00,000 | 6–10 weeks | Includes site safety audit |
| Explosives Manufacturing / Storage | ₹50,000 + audit charges | 10–16 weeks | Requires DPIIT industrial licence for LE-1 |
| SMPV (Unfired) Pressure Vessel Approval | ₹20,000–₹40,000 | 8–10 weeks | Based on design review |
Fees vary by product category, volume, and capacity. Digital filing reduces processing time by nearly 30%.
A single documentation error can delay your application by months. Having a compliance expert manage the process minimizes this risk.
In short, skipping PESO approval can cost more than the certification itself.
Many startups and MSMEs delay applying until just before product launch — only to discover that PESO’s technical scrutiny can take 60–90 days.
Registering your design, facility, or equipment early in the project cycle ensures you can start operations or shipments on time.
Proactive compliance also positions your brand as a trusted and safety-conscious supplier, opening doors to PSU tenders, export orders, and insurance benefits.

Yes. Any unit storing or transporting compressed gas or petroleum under pressure must hold a valid PESO licence.
No. They must appoint an Authorized Indian Representative (AIR) who is responsible for compliance, renewals, and liaison with PESO.
Generally five years for plant licences and three years for Ex equipment approvals.
No. These are supporting documents; PESO conducts its own safety validation under Indian law.
You must file an amendment or new application within 30 days to keep the approval valid.
