Investing in a manufacturing project involves more than assessing production capacity, machinery, financial performance and market demand. A facility can appear operationally sound while carrying expired approvals, unresolved regulatory notices, capacity mismatches or restrictions that affect future expansion. Regulatory due diligence for manufacturing projects helps investors identify these issues before they become unexpected costs or operational constraints.

The objective is not simply to collect copies of licences. It is to determine whether the facility is legally authorised to operate as it does today, whether its compliance position is sustainable, and whether the investor's future plans can be executed within the applicable regulatory framework.

What Is Regulatory Due Diligence for a Manufacturing Project?

Regulatory due diligence for manufacturing project , is a structured review of the approvals, licences, registrations, permits, compliance records and regulatory obligations associated with a manufacturing facility or proposed project.

The assessment should answer four practical questions:

• What is the facility legally permitted to do?

• Is the facility currently operating within those permissions?

• Are there unresolved regulatory liabilities or compliance gaps?

• Can the proposed investment, expansion or modification proceed without creating new regulatory obstacles?

India's National Single Window System illustrates the breadth of the approval landscape. Its Know Your Approvals module provides guidance covering 32 Central Departments and 35 States, while applications are hosted for approvals from 32 Central Departments and 34 State Governments. NSWS itself also cautions that its KYA tool is a guidance mechanism and that relevant government portals should be checked for additional requirements.

This means regulatory due diligence should be project-specific, rather than based on a generic licence checklist.

Why Regulatory Due Diligence Matters Before Investment

The most important risk is often the gap between what the documents say and what the facility actually does.

For example, an investor may discover that:

• Production capacity exceeds the capacity reflected in an approval.

• A manufacturing process has changed without corresponding regulatory modification.

• The current plant layout differs from an approved plan.

• Environmental permissions do not reflect the present operation.

• A licence is valid but its scope does not cover the full product range.

• Previous inspection observations remain unresolved.

• An approval is approaching expiry.

• A planned expansion requires additional permissions.

These findings can influence project timelines, remediation costs, expansion plans and transaction conditions. Regulatory due diligence therefore becomes an important input into investment planning rather than a paperwork exercise performed after the commercial assessment.

8 Key Regulatory Checks Before Investing

1. Verify the Approval and Licence Universe

Start by identifying every approval applicable to the project's location, industry, process, products, capacity and operating conditions.

Depending on the facility, this may include:

• Factory registration and licence

• Environmental approvals

• Consent to Establish and Consent to Operate

• Fire and life-safety approvals

• Waste-management authorisations

• Product-specific certifications

• FSSAI permissions

• CDSCO or drug-related licences

• BIS certification

• PESO or other special permissions

• Labour and occupational safety registrations

Do not assume that an approval appearing on a document list is automatically applicable, current or sufficient.

2. Compare Approved Capacity With Actual Capacity

Capacity mismatch is one of the most useful checks in manufacturing due diligence.

Compare:

Approved capacity → Actual capacity → Proposed future capacity

The same comparison should be made for production lines, products and major processes.

An investor should ask whether current output, installed equipment and planned expansion remain within the scope of applicable permissions.

This is especially important for brownfield projects, where facilities may have evolved through several expansion phases.

3. Check Environmental Compliance

Environmental compliance should be assessed against the facility's actual environmental footprint, not merely the existence of an approval.

Review:

• Environmental Clearance, where applicable

• Consent to Establish

• Consent to Operate

• Air and water pollution requirements

• Hazardous-waste authorisations

• Waste-management records

• Environmental monitoring reports

• Compliance submissions

• Notices and directions

The regulatory framework is continuing to evolve. In 2026, the government introduced amendments to the Uniform Consent Guidelines, including provisions relating to consolidated consent and authorisation for certain environmental permissions.

The critical question is therefore:

Do the facility's current processes, production levels and pollution controls correspond with the permissions on record?

4. Review Factory, Safety and Labour Compliance

A manufacturing facility should also be assessed for occupational safety and working-condition requirements.

Check:

• Factory licence and approved plans

• Worker capacity

• Machinery and process configuration

• Safety systems

• Emergency arrangements

• Accident records

• Inspection observations

• Statutory registers and returns

• Contractor-related obligations

The Occupational Safety, Health and Working Conditions Code, 2020 has an enforcement date of 21 November 2025, making current occupational-safety requirements an important part of contemporary manufacturing compliance reviews.

The review should establish whether the site's current workforce, machinery and operations correspond with its regulatory documentation.

5. Examine Fire and Life-Safety Status

Fire compliance deserves separate attention because facilities can change significantly after their original approval.

Compare:

Approved layout → Current layout

and:

Approved storage/process conditions → Current conditions

Review the fire NOC or applicable approval, fire-safety systems, emergency exits, hydrants, sprinklers, detection systems, fire-water arrangements, inspection observations and pending corrective actions.

A facility should not be treated as fully compliant simply because it possesses an older fire approval. Physical changes made after approval may require additional assessment or modification.

6. Verify Product-Specific Regulatory Compliance

Product regulation varies substantially by industry.

For pharmaceuticals, review manufacturing licences, product permissions, GMP-related compliance and inspection history. For food processing, assess FSSAI licensing and whether the licence reflects the facility's products and operations. For products covered by mandatory standards, verify the applicable BIS requirements and certification scope.

The importance of this check is demonstrated by recent pharmaceutical enforcement activity. CDSCO and State Drugs Controllers reported more than 960 risk-based inspections of drug-manufacturing premises since December 2022, followed by more than 860 regulatory actions based on findings.

Therefore, an investor should review not only current licences but also inspection findings, corrective actions and regulatory history.

7. Investigate Historical Regulatory Issues

Current approvals provide only part of the picture.

Review:

• Show-cause notices

• Inspection reports

• Penalties

• Suspension or cancellation orders

• Environmental directions

• Fire objections

• Product recalls

• Regulatory correspondence

• Pending corrective actions

• Litigation or proceedings involving material regulatory issues

The key question is:

Are there historical issues that could create continuing obligations or costs after the investment?

This is particularly important in acquisitions, where historical compliance conditions may affect the practical risk profile of the facility.

8. Test Future Expansion Feasibility

An investment decision should consider not only whether the plant can operate today, but whether it can support the investor's intended growth strategy.

Map:

Existing approvals → Existing operation → Proposed modification → Additional approvals required

For example, increasing production, introducing a new product, changing a process, modifying a building or increasing pollution load can alter the applicable regulatory requirements.

This makes regulatory due diligence particularly valuable for brownfield acquisitions and capacity-expansion projects.

A Practical Regulatory Due Diligence Matrix

A simple matrix can convert a large document review into an investment-oriented assessment:

This approach gives decision-makers something more useful than a folder containing approval copies: a clear picture of where regulatory exposure exists and what needs attention.

Greenfield vs Brownfield Regulatory Due Diligence

The focus changes depending on the project.

Greenfield Projects

The assessment should concentrate on:

• Site and land-use suitability

• Pre-establishment approvals

• Environmental requirements

• Construction-related permissions

• Factory and fire requirements

• Product-specific approvals

• Pre-operation permissions

• Future expansion constraints

Brownfield Projects

The assessment should additionally investigate:

• Existing approval validity

• Historical violations

• Legacy environmental issues

• Previous expansion activity

• Actual versus approved capacity

• Existing equipment and layout changes

• Pending regulatory actions

• Licence modifications

• Future expansion requirements

For brownfield investments, historical compliance is as important as current compliance.

Documents to Request Before Investment

A practical document request should cover:

• Land and property documents

• Site and approved layout plans

• Regulatory licences and registrations

• Environmental permissions

• Pollution-control consents

• Fire approvals

• Factory approvals

• Product-specific licences

• Waste-management records

• Inspection reports

• Compliance submissions

• Notices and orders

• Renewal records

• Production-capacity information

• Product and process details

• Records of proposed expansion

The documents should then be verified against the physical facility and actual operating conditions.

Common Mistakes in Regulatory Due Diligence

Avoid treating regulatory due diligence as:

• A simple licence-counting exercise

• A review of only current certificates

• A purely document-based exercise

• A generic checklist applicable to every industry

• A review that ignores future expansion

• A process that overlooks historical notices

• A legal review disconnected from plant operations

The strongest assessment connects regulation, engineering, operations and the investment plan.
