PESO License for Chemical & Hazardous Manufacturing: Foreign Company Guide

What Is PESO and Why Foreign Companies Need It

The Petroleum and Explosives Safety Organisation (PESO) is an office of the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry, that regulates the manufacture, import, storage, and transport of petroleum products, explosives, compressed gases, and hazardous substances. Any foreign company planning to manufacture chemicals, store petroleum products, operate pressure vessels, or handle explosive materials in India must obtain a PESO license before commencing operations.

PESO traces its origin to the Department of Explosives set up under the Explosives Act, 1884. Its head office is the Chief Controller of Explosives at Nagpur, working through Circle and Sub-Circle offices across the country. For foreign companies, PESO compliance is not optional — operating without a licence can result in facility closure, seizure of stock and equipment, and imprisonment of the persons in charge for up to three years under section 9B(1)(a) of the Explosives Act, 1884.

If you are establishing a foreign subsidiary or wholly owned subsidiary for manufacturing in India, PESO licensing is one of the earliest approvals you must secure — often in parallel with environmental clearance and state factory licensing.

Key Legislation Governing PESO Licenses

PESO derives its authority from multiple laws. Foreign companies must understand which acts apply to their specific operations:

For chemical manufacturers, the most relevant are typically the Petroleum Rules 2002, the SMPV(U) Rules 2016, and — if dealing with raw materials that qualify as explosives — the Explosives Rules 2008.

PESO License Categories for Foreign Companies

PESO issues different license types depending on the activity and substance involved. Foreign companies typically need one or more of these:

1. Manufacturing License

Required for companies manufacturing petroleum products, explosives, gas cylinders, pressure vessels, or explosion-proof equipment in India. This is the most common license for foreign manufacturers setting up Indian plants. The license covers the manufacturing facility, processes, safety equipment, and quality management systems.

2. Storage License

Required for storing petroleum, compressed gases, or explosive materials beyond specified threshold quantities. The exemption thresholds are set by the Petroleum Act, 1934 itself: no licence is needed to store petroleum Class B up to 2,500 litres (with no single receptacle over 1,000 litres) or petroleum Class C up to 45,000 litres (section 7), while for petroleum Class A the exemption is only 30 litres and only where it is not intended for sale (section 8). Above those limits a licence under the Petroleum Rules, 2002 is required. Storage of compressed or liquefied gas in pressure vessels is licensed separately under the SMPV(U) Rules, 2016.

3. Import License

Foreign companies importing gas cylinders, pressure vessels, explosion-proof equipment, or explosives into India need PESO import approval. This applies even if the goods are manufactured by a certified facility abroad — PESO requires independent certification for Indian import.

4. Transport License

Transporting petroleum products, explosives, or compressed gases in bulk requires a PESO transport license. Companies operating tanker fleets or transporting chemicals between manufacturing and storage sites need this approval.

5. Gas Cylinder Filling License

For companies operating LPG, CNG, industrial gas, or medical oxygen cylinder filling stations. This requires strict facility inspection including valve testing, pressure testing equipment, and safety infrastructure.

6. Explosion-Proof Equipment Approval

Foreign companies manufacturing or importing electrical equipment for use in hazardous (Ex-rated) environments — refineries, chemical plants, mines, oil rigs — must get PESO type-approval for each product model.

The Authorized Indian Representative (AIR) Requirement

This is the requirement that catches most foreign companies off guard. PESO mandates that every foreign manufacturer or importer appoint an Authorized Indian Representative (AIR) — a registered Indian entity that acts as the liaison between the foreign company and PESO.

AIR Responsibilities

• Filing and managing PESO applications on behalf of the foreign company
• Coordinating facility inspections and document submissions
• Handling post-approval regulatory correspondence
• Providing after-sales support and local technical assistance
• Maintaining compliance records accessible to PESO inspectors
• Receiving and responding to show-cause notices or compliance queries

The AIR must be an entity registered in India, evidenced by a certificate of incorporation, registered partnership deed or LLP registration, or a GST certificate with PAN for a proprietorship. Many foreign companies appoint their Indian subsidiary, a local distributor or a specialised regulatory consultancy. PESO's standard operating procedure for approval of Ex electrical apparatus requires a letter of authorisation addressed to the Chief Controller of Explosives, issued by the original equipment manufacturer, authorising the Indian service provider or distributor to apply on its behalf, together with a service agreement covering spares, repair, commissioning and after-sales service. Confirm the current attestation requirements with the jurisdictional office before signing — they are set administratively rather than by the Rules.

Application Process Through NSWS Portal

Since 2022, all PESO applications are submitted through the National Single Window System (NSWS) portal at nsws.gov.in or the dedicated PESO portal at online.peso.gov.in. The process follows these steps:

Step 1: Registration

Create a user account on the NSWS portal using the company's PAN and Digital Signature Certificate (DSC). Foreign companies must have their Indian entity registered first — PESO applications cannot be filed by foreign entities directly.

Step 2: Select License Type

Navigate to the PESO module within NSWS and select the specific license type (manufacturing, storage, import, etc.). The portal will generate a checklist of required documents based on your selection.

Step 3: Upload Documents

All documents must be uploaded digitally. Typical requirements include:

• Company incorporation certificate and Memorandum of Association
• Factory layout drawings (AutoCAD format preferred) showing safety zones, storage areas, and emergency exits
• Technical drawings and specifications of equipment/products
• ISO quality management certificates (ISO 9001, ISO 14001)
• Test reports from NABL-accredited laboratories
• IECEx or ATEX certificates (for explosion-proof equipment)
• Quality Assurance Plan (QAP) document
• Letter of authorisation to the Chief Controller of Explosives plus service agreement (for foreign manufacturers acting through an Indian representative)
• Fire safety clearance from the local fire department
• Environmental clearance from the State Pollution Control Board

Step 4: Fee Payment

Pay the applicable fees online. PESO's statutory fees are modest and are fixed by the fee schedule attached to each set of Rules — not negotiated case by case. Representative figures taken directly from those schedules:

The statutory fee is rarely the material cost. Budget instead for third-party testing, competent-person inspection, consultant support and the facility works that inspection observations generate — these routinely run to several lakhs or more.

Step 5: Facility Inspection

PESO dispatches inspectors to the manufacturing or storage site. The inspection covers:

• Safety infrastructure: fire fighting systems, gas detection systems, emergency shutdown systems
• Layout compliance: safety distances between storage areas, process areas, and boundary walls
• Equipment testing: pressure testing of vessels, valve integrity, electrical safety
• Documentation: safety manual, emergency response plan, operator training records
• Environmental controls: spillage containment, effluent treatment, waste management

For foreign companies, the inspection is often the most time-consuming step. Inspectors may raise observations requiring modifications before approval is granted.

Step 6: License Issuance

Upon successful inspection and document verification, PESO issues the approval certificate. The certificate specifies the exact scope — products, quantities, locations — covered by the license.

Processing Timeline and Validity

In practice, foreign companies should budget 3-4 months for the complete process. Incomplete documentation or inspection observations can extend this to 5-6 months. The timings in the table above are practitioner estimates, not statutory service levels — the Rules do not fix a decision deadline, so first-time-right documentation is the only reliable way to compress the schedule.

Penalties for Non-Compliance

Operating without a valid PESO license carries severe consequences:

• Facility closure: PESO can order immediate shutdown of non-compliant manufacturing or storage operations
• Imprisonment: Under section 9B of the Explosives Act, 1884, manufacturing, importing or exporting an explosive in contravention of the rules or licence conditions carries up to 3 years' imprisonment, and possessing, using, selling or transporting one carries up to 2 years. Under section 23 of the Petroleum Act, 1934, a contravention carries up to one month's simple imprisonment, rising to three months for a repeat offence
• Financial penalties: The statutory fines are small — up to INR 5,000 under section 9B(1)(a) of the Explosives Act and up to INR 1,000 (INR 5,000 on repetition) under section 23 of the Petroleum Act. The commercial exposure comes from shutdown, seizure and contract loss, not from the fine itself
• Insurance exposure: Industrial policies routinely require the insured to hold and comply with all statutory licences, so operating without PESO certification can give the insurer grounds to decline a claim — a catastrophic risk for a chemical plant
• Government blacklisting: Non-compliant companies are blacklisted from government contracts and public procurement tenders
• Seizure of goods: PESO can seize hazardous materials, equipment, and manufactured goods found at unlicensed facilities

Integrating PESO with Other Approvals

PESO licensing does not exist in isolation. Foreign companies setting up chemical or hazardous manufacturing in India need a matrix of parallel approvals:

The recommended approach is to begin PESO and environmental clearance applications simultaneously, as both involve site inspections and can take 3-4 months. Factory licensing can often be processed in parallel.

Common Mistakes Foreign Companies Make

• Not appointing an AIR early enough: The Authorized Indian Representative must be in place before filing the PESO application. Last-minute AIR appointments delay the entire process
• Incomplete technical drawings: PESO requires detailed facility layout drawings with exact safety distances. Generic drawings from the foreign parent are rejected — Indian-specific layouts are required
• Ignoring state-level clearances: PESO is a central government body, but environmental and factory clearances are state-level. Foreign companies sometimes obtain PESO approval but cannot operate because state clearances are pending
• Letting licences lapse: the renewal application must reach the licensing authority on or before the expiry date under all four rule sets. Miss the outer limit — three months after expiry for an explosives licence (Explosives Rules r.112(10)), one year under the SMPV(U) Rules (r.55(8)), the Gas Cylinders Rules (r.55(8)) and the Petroleum Rules (r.148(8)) — and renewal is barred outright, leaving a fresh application from scratch
• Underestimating inspection preparation: PESO inspectors conduct thorough physical inspections. Safety equipment must be installed and operational — not just ordered — before the inspection

Key Takeaways

• PESO licensing is mandatory for all chemical, petroleum, compressed gas, and explosives manufacturing, storage, import, and transport operations in India
• Foreign companies must appoint an Authorized Indian Representative (AIR) — a registered Indian entity — before filing any PESO application
• All applications are processed through the NSWS portal; expect 45-90 working days for approval. Statutory fees are modest — capped at INR 50,000 a year for a petroleum installation licence and INR 50,000 for an SMPV storage licence — with the real cost sitting in testing, inspection and facility works
• Validity now runs to ten years under every rule set — ten years under the Petroleum Rules (to 31 December), ten financial years under the Explosives Rules (to 31 March), and ten years under the SMPV(U) and Gas Cylinders Rules (both to 30 September) — and the renewal application must reach the licensing authority on or before the expiry date
• Non-compliance consequences include facility closure, seizure of stock, imprisonment of up to 3 years under section 9B of the Explosives Act, 1884, and loss of insurance cover — the statutory fines themselves are small
• Chemical manufacturing FDI is 100% under the automatic route in most sectors, but PESO and environmental clearances must be obtained before operations begin
