PESO Certificate — Meaning, Benefits, Process, Penalties & Complete Guide

A PESO Certificate is an official approval issued by the Petroleum and Explosives Safety Organisation — the regulatory authority under the Government of India that administers safety standards for petroleum, explosives, compressed gases, pressure vessels, and hazardous products.

This certification validates that products, equipment, factories, or operations involving flammable, explosive, or high-pressure materials comply with Indian safety laws, including:

• Explosives Act, 1884

• Petroleum Act, 1934

• Gas Cylinder Rules, 2016

• Static and Mobile Pressure Vessels (Unfired) Rules, 2016

Simply put, a PESO certificate ensures safety and legal compliance for products used in explosive atmospheres, oil and gas sectors, and high-risk environments.

A PESO Certificate is mandatory for the following businesses and products:

1. Manufacturers and Importers

• Gas cylinders (LPG, oxygen, nitrogen, etc.) and valves

• Flameproof / explosion-proof electrical equipment

• Pressure vessels, storage tanks, and industrial gas systems

• Equipment used in hazardous areas (oil & gas, mining, chemical plants)

2. Storage, Handling and Distribution Units

• Petroleum storage facilities and depots

• Explosive material warehouses and handling units

• Chemical and compressed gas distribution networks

3. Foreign OEMs (Original Equipment Manufacturers)

Foreign companies supplying hazardous-area products to India must obtain PESO Approval via an Authorized Indian Representative (AIR) to import or sell their products legally.

In essence, any entity dealing with flammable liquids, gases, explosive materials, pressure systems or hazardous equipment must secure PESO certification before manufacturing, installing, importing, or selling such products within India.

1. Legal Compliance

Without PESO certification, you cannot manufacture, operate, or sell regulated products or services — failure to comply may result in shutdowns, fines, or legal action.

2. Safety Assurance

PESO certification ensures equipment and operations are safe for use in explosive or flammable environments, greatly reducing accident risks.

3. Market Access

Government projects, industrial buyers, and tender eligibility often require PESO-approved products as a mandatory criterion.

4. Insurance and Liability Protection

Insurance claims can be invalidated if incidents occur in installations operating without the proper PESO approvals.

5. Export & Import Compliance

Foreign exporters and importers require PESO clearance to clear Indian customs and fulfil regulatory obligations.

1. Determine Applicable Regulations

Identify whether your product falls under Explosives Rules, Gas Cylinder Rules, SMPV (Unfired) Rules, or Petroleum Rules based on its application and risk category.

2. Engage Certified Testing and Documentation

Products, especially those used in explosive atmospheres, must have valid test reports from recognized international standards such as IECEx or ATEX, ideally not older than two years.

3. Appoint an Indian Authorized Representative (AIR)

Foreign manufacturers must designate an AIR — a registered Indian entity responsible for submitting the PESO application, liaising with authorities, and handling compliance post-approval.

4. Prepare Required Documents

Typical documents include:

• Application form

• Technical drawings and product specs

• Test reports (IECEx/ATEX/NABL as applicable)

• Business and commercial data

• ISO/Quality certifications

• AIR authorization letter

5. Submit Application via PESO / NSWS Portal

Complete online application on the National Single Window System (NSWS) linked with PESO modules and upload all documents with prescribed fees.

6. Review, Queries and Inspection

PESO officials will scrutinize the submission, may raise queries, and require clarifications or additional verifications. Physical inspection may be necessary for certain product types such as pressure vessels.

7. Approval and Certificate Issuance

Upon successful verification and compliance, PESO will issue a digital certificate valid generally for 3–5 years, after which renewal is mandatory.

Typical approval timelines range from 60 to 120 days depending on product complexity and documentation readiness.

While documents may vary by product, the common requirements include:

• Company registration & GST certificates

• Product technical details and specifications

• Valid IECEx/ATEX certificates and test reports

• Commercial data (sales, clients, use cases)

• ISO or quality system certificates

• AIR authorization agreement (for foreign firms)
