Chemical Manufacturing in India: PESO, Environmental Clearance & FDI Rules

India's Chemical Manufacturing Opportunity for Foreign Investors

India's chemical industry is currently valued at approximately USD 250 billion and is projected to reach USD 383 billion by 2030, doubling its global industry share to 6%. The sector has attracted USD 23.4 billion in cumulative FDI between April 2000 and June 2025, making it one of the most active manufacturing sectors for foreign investment in the country.

The opportunity is driven by multiple structural factors: China-plus-one supply chain diversification, India's growing domestic consumption of chemicals, a USD 18.7 billion government allocation to the Ministry of Chemicals and Fertilizers in Budget 2025-26, and production-linked incentive (PLI) schemes targeting specialty chemicals, agrochemicals, and petrochemicals.

For foreign chemical companies evaluating India manufacturing, the regulatory landscape involves three distinct but interconnected compliance frameworks: FDI policy approvals, safety licensing through PESO and related bodies, and environmental clearances. Each operates independently, and all must be satisfied before production can commence.

FDI Policy for Chemical Manufacturing

Chemical manufacturing in India permits 100% foreign direct investment under the automatic route for most sub-sectors. This means foreign companies can establish wholly-owned manufacturing subsidiaries without prior government approval for the investment itself.

Sub-Sector FDI Rules

Investment from Land-Border Countries

As of March 10, 2026, FDI from entities based in countries sharing a land border with India (China, Pakistan, Bangladesh, Nepal, Myanmar, Bhutan, Afghanistan) requires prior government approval, regardless of the sector. For Chinese chemical companies — a significant source of global chemical investment — this adds approximately 60 days to the approval timeline under the amended policy's streamlined manufacturing pathway.

Entity Structure for Chemical Manufacturing FDI

Foreign chemical companies typically enter India through one of two entity structures:

• Wholly-owned subsidiary (WOS): A private limited company incorporated under the Companies Act, 2013, with 100% foreign shareholding. This is the most common structure, providing full operational control and liability protection
• Joint venture with an Indian partner: Preferred when the foreign company needs access to local land, existing manufacturing infrastructure, distribution networks, or political relationships. Joint ventures are particularly common in petrochemicals and bulk chemicals where Indian conglomerates hold significant market positions

The incorporation process uses the SPICe+ form, followed by FC-GPR filing within 30 days of share allotment. For companies evaluating the right entity type, our branch office vs subsidiary comparison provides a detailed analysis.

PESO Licensing: The Safety Compliance Framework

The Petroleum and Explosives Safety Organisation (PESO), operating under the Department for Promotion of Industry and Internal Trade (DPIIT) in the Ministry of Commerce and Industry, is the statutory authority governing the manufacture, storage, transport, import, and use of petroleum products, explosives, compressed gases, and hazardous materials in India.

PESO currently regulates over 256,000 premises across India. For chemical manufacturing, PESO licensing is mandatory if the facility handles any of the following categories:

Categories Requiring PESO Licensing

• Petroleum products: Any facility manufacturing, storing, or processing petroleum-based chemicals (crude derivatives, solvents, petrochemical intermediates)
• Compressed and liquefied gases: Facilities manufacturing, filling, storing, or transporting compressed gases including industrial gases (oxygen, nitrogen, hydrogen, acetylene)
• Explosives and propellants: Manufacturing of explosives, detonators, fireworks, or any explosive precursor chemicals
• Ammonium nitrate: Specific licensing required for manufacture, possession, sale, bagging, storage, and stevedoring of ammonium nitrate under the Ammonium Nitrate Rules, 2012
• Pressure vessels: Manufacture or operation of pressure vessels, gas cylinders, and their fittings
• Calcium carbide and acetylene: Calcium carbide factories and acetylene gas generating plants

Key PESO Licence Types for Chemical Manufacturers

PESO Licence Application Process

1. Online application: Submit through the PESO online portal (peso.gov.in) with facility layout drawings, safety assessments, material safety data sheets, and proposed storage quantities
2. Document verification: PESO reviews the application for completeness and compliance with applicable rules (typically 15-30 days)
3. Site inspection: A PESO inspector conducts a physical inspection of the facility to verify safety infrastructure, fire protection systems, distance compliance, and personnel training
4. Licence issuance: Upon satisfactory inspection, PESO issues the licence with specific conditions on storage quantities, safety equipment, and operational procedures
5. Renewal: Most PESO licences are valid for 1-5 years and must be renewed before expiry

PESO Compliance Costs

PESO licence fees vary by type and scale of operations. Typical costs for a medium-scale chemical manufacturing facility include:

• Licence application fee: INR 5,000-50,000 (varies by licence type)
• Annual renewal fee: INR 2,000-25,000
• Inspection charges: INR 10,000-50,000 per inspection
• Safety infrastructure compliance (fire protection, containment, ventilation): INR 25-100 lakh depending on facility scale and materials handled

Environmental Clearance: The EIA Framework

Chemical manufacturing is classified as a potentially high-polluting industry under India's environmental regulations. The Environmental Impact Assessment (EIA) Notification 2006, issued under the Environment (Protection) Act, 1986, mandates prior environmental clearance for all new chemical manufacturing projects and expansions of existing facilities listed in the notification's schedule.

Project Categorisation

Chemical manufacturing projects are categorised based on their production capacity, location, and type of chemicals produced:

Environmental Clearance Process

1. Screening (Category B only): The SEIAA determines whether the project requires a full EIA study (B1) or can proceed with simplified appraisal (B2)
2. Scoping: The Expert Appraisal Committee (EAC) at the central level or State EAC at the state level defines the Terms of Reference (ToR) for the EIA study. This step takes 30-60 days
3. EIA study: A NABET-accredited consultant conducts the environmental impact assessment, including baseline environmental data collection (minimum one season), impact prediction, and mitigation plans. Timeline: 6-12 months
4. Public consultation: For Category A and B1 projects, a public hearing must be conducted in the project-affected area. This is organised by the State Pollution Control Board (SPCB) within 45 days of receiving the draft EIA
5. Appraisal: The EAC reviews the final EIA report, public hearing transcript, and recommends approval, modification, or rejection. Timeline: 60-90 days
6. Grant of EC: The MoEFCC (for Category A) or SEIAA (for Category B) issues the Environmental Clearance with specific conditions on emissions, effluents, waste management, and monitoring. Timeline: 30-45 days after EAC recommendation

All applications must be submitted through the PARIVESH 2.0 online portal (parivesh.nic.in), which provides integrated project submission, clearance tracking, and compliance monitoring.

Total Environmental Clearance Timeline

Pollution Control Board Approvals

Independent of the environmental clearance process, every chemical manufacturing facility requires approvals from the Central Pollution Control Board (CPCB) and the relevant State Pollution Control Board (SPCB) under the Air (Prevention and Control of Pollution) Act, 1981 and the Water (Prevention and Control of Pollution) Act, 1974.

Required Approvals

• Consent to Establish (CTE): Must be obtained before construction of the manufacturing facility begins. The CTE specifies the pollution control equipment, effluent treatment capacity, and emission standards that must be installed
• Consent to Operate (CTO): Must be obtained after construction and before commercial operations commence. The SPCB inspects the installed pollution control systems and verifies compliance with the CTE conditions
• Hazardous Waste Authorization: Under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, any facility generating, storing, treating, or disposing of hazardous waste must obtain authorization from the SPCB
• Continuous Emission and Effluent Monitoring Systems (CEMS/OCEMS): Red category industries — which includes most chemical manufacturing — must install real-time online monitoring systems connected to the CPCB/SPCB servers

Industry Categorisation: Red, Orange, Green, White

The CPCB classifies industries into four categories based on their Pollution Index (PI), which is a composite score factoring in air emissions, water effluents, hazardous waste generation, and resource consumption:

Red category classification — which covers most chemical manufacturing — triggers the most stringent compliance requirements: annual environmental audits, continuous emission monitoring, quarterly compliance reports, and mandatory Form V (Annual Environment Statement) filing.

Manufacture, Storage and Import of Hazardous Chemicals (MSIHC) Rules

The MSIHC Rules, 1989 (as amended in 1994 and 2000) are the primary legislation governing the manufacture and storage of hazardous chemicals in India. These rules apply to all facilities handling chemicals listed in the three schedules appended to the rules.

Key Obligations Under MSIHC Rules

• Notification to authorities: Any facility handling listed hazardous chemicals must notify the Chief Inspector (Factories) and the concerned authorities at least 90 days before commencing operations
• Safety report: Facilities handling chemicals above threshold quantities must prepare and submit a detailed safety report covering risk assessment, worst-case scenario analysis, and emergency response plans
• On-site emergency plan: Every hazardous chemical facility must have a tested on-site emergency plan, updated annually, with trained emergency response teams
• Off-site emergency plan: The District Collector prepares the off-site emergency plan based on information provided by the occupier, covering evacuation procedures, medical emergency response, and environmental containment
• Material Safety Data Sheets (MSDS): Must be maintained for every hazardous chemical at the facility and made accessible to all workers and emergency responders

The Factories Act and State-Level Approvals

Chemical manufacturing facilities are governed by the Factories Act, 1948, which mandates factory registration with the state's Chief Inspector of Factories, compliance with working hours, safety standards, and welfare provisions for workers.

Additional State-Level Approvals

• Factory licence: Registration under the Factories Act is mandatory for all manufacturing establishments employing 10+ workers (with power) or 20+ workers (without power)
• Fire NOC: Clearance from the state fire services department, particularly critical for chemical facilities storing flammable materials
• Land use conversion: If the facility is on agricultural land, conversion to industrial use must be obtained from the state revenue authority
• Trade licence: Municipal/local body trade licence for operating a business at the specific location
• Drug licence (for pharmaceutical chemicals): If manufacturing pharmaceutical intermediates or active pharmaceutical ingredients, additional Drug Controller General of India (DCGI) approvals are required

Production-Linked Incentive (PLI) Scheme for Chemicals

The Indian government has introduced PLI schemes covering certain chemical sub-sectors to attract foreign investment in domestic manufacturing. Foreign chemical companies establishing manufacturing in India may be eligible for:

• PLI for specialty chemicals: Incentive of 4-6% of incremental sales over a 5-year period for manufacturers of specified specialty chemical products
• PLI for bulk drugs/APIs: Capital incentive of up to 20% of investment for greenfield API manufacturing facilities (fermentation-based products attract higher incentives)
• PLI for advanced chemistry cell batteries: Manufacturing incentive for lithium-ion and other advanced battery cell production

PLI applications are evaluated by the concerned ministry and approval requires demonstrated investment commitment, technology capability, and employment generation targets.

Tax Considerations for Chemical Manufacturing FDI

Foreign-owned chemical manufacturing companies in India are taxed as domestic companies. The key tax provisions include:

• Corporate tax: Standard rate of 22% (effective 25.17% with surcharge and cess) under Section 115BAA, or the manufacturing incentive rate of 15% (effective 17.16%) under Section 115BAB for new manufacturing companies incorporated after October 1, 2019 and commencing production before March 31, 2024
• GST: Chemical products attract GST rates of 5%, 12%, 18%, or 28% depending on the specific product. Input tax credits on capital goods and raw materials are available for set-off
• Customs duty: Import duty on chemical raw materials ranges from 0% to 15% depending on the product and applicable Free Trade Agreements. The EPCG and Advance Authorization schemes permit duty-free import of capital goods and raw materials for export-oriented production
• Transfer pricing: Intercompany transactions between the Indian manufacturing entity and the foreign parent — including raw material supply, technology licensing, and management fees — must comply with arm's length pricing requirements with contemporaneous documentation

SEZ and Industrial Park Options

Foreign chemical companies may consider establishing manufacturing facilities in Special Economic Zones (SEZs) or state-designated industrial parks/chemical zones to benefit from:

• Pre-approved land with industrial zoning (eliminates land use conversion delays)
• Existing common effluent treatment plants (CETP) and waste management infrastructure
• Simplified single-window clearance for environmental and factory approvals
• State-level incentives including stamp duty exemption, electricity duty waiver, and capital investment subsidies
• Proximity to ports, highways, and logistics infrastructure

Major chemical industrial zones include Dahej and Ankleshwar in Gujarat, Patalganga and Kurkumbh in Maharashtra, Visakhapatnam in Andhra Pradesh, and the upcoming Petroleum, Chemicals and Petrochemicals Investment Regions (PCPIRs) in Andhra Pradesh and Gujarat.

Common Compliance Mistakes by Foreign Chemical Investors

1. Starting Construction Before Environmental Clearance

This is the most common and most costly mistake. Any construction activity on a project requiring environmental clearance — including site preparation, foundation work, and equipment installation — is prohibited before the EC is granted. Violations attract penalties under the Environment (Protection) Act and may result in mandatory demolition.

2. Underestimating PESO Timeline

PESO licensing can take 3-6 months including site inspection. Foreign companies often assume it is a formality, but PESO inspectors are thorough and may require multiple rounds of corrections to safety infrastructure before granting the licence.

3. Ignoring MSIHC Notification Requirements

The 90-day advance notification requirement under MSIHC Rules is frequently overlooked by foreign companies, particularly when they are unfamiliar with the specific chemicals listed in the MSIHC schedules. Non-compliance can result in prosecution under the Environment (Protection) Act.

4. Not Appointing a Qualified Occupier

Under the Factories Act and MSIHC Rules, every hazardous chemical facility must designate an "occupier" who is personally responsible for safety compliance. This must be a person with direct authority over the facility's operations — not a remote director or the foreign parent company's nominee.

5. Inadequate Transfer Pricing Documentation for Intercompany Raw Material Transfers

Chemical companies frequently transfer proprietary raw materials, intermediates, or formulations from the parent to the Indian subsidiary. Without robust transfer pricing documentation demonstrating arm's length pricing, the Indian tax authorities will reassess these transactions, resulting in additional tax liability, interest, and penalties.

Import and Export Compliance for Chemical Manufacturers

Foreign-owned chemical manufacturers importing raw materials or exporting finished products must comply with India's foreign trade regulations:

Import-Export Code (IEC)

An Import Export Code from the Directorate General of Foreign Trade (DGFT) is mandatory for all import and export transactions. Application is online through the DGFT portal, and the IEC is typically issued within 3-5 working days.

Hazardous Chemical Import Controls

Import of chemicals listed under the MSIHC Rules requires prior notification to the concerned port authority at least 30 days before the expected date of import. Certain chemicals under the Chemical Weapons Convention (CWC) require end-user certification. Pesticides and insecticides require import registration under the Insecticides Act, 1968 from the Central Insecticides Board.

Customs and BIS Certification

Chemicals covered under the Bureau of Indian Standards (BIS) mandatory certification scheme require BIS certification before they can be imported or sold in India. The Foreign Trade Policy 2023 provides specific duty concessions for chemical raw materials used in domestic manufacturing through Advance Authorization and EPCG schemes.

Responsible Care and Sustainability Compliance

India's chemical industry is increasingly moving towards international sustainability standards. The Indian Chemical Council (ICC) promotes the Responsible Care initiative, and many foreign chemical companies find that compliance with global ESG standards — including BRSR reporting requirements for listed companies — provides a competitive advantage in the Indian market. The CPCB requires annual environmental audits (Form V) and mandatory disclosure of emissions data for Red category industries.

Key Takeaways

• 100% FDI is permitted under the automatic route for most chemical manufacturing sub-sectors, with no prior government approval required (except for land-border country entities)
• PESO licensing is mandatory for facilities handling petroleum products, compressed gases, explosives, ammonium nitrate, and pressure vessels — plan for a 3-6 month licensing timeline
• Environmental clearance under EIA 2006 takes 12-18 months for Category A projects and 8-14 months for Category B1 — construction cannot begin without EC
• Pollution control approvals (CTE and CTO) from the SPCB are independent of environmental clearance and must be obtained before construction and operations respectively
• The effective corporate tax rate can be as low as 17.16% for new manufacturing companies under Section 115BAB, and PLI schemes offer additional 4-6% incentives on incremental sales
