Pharma Plant Acquisition Checklist for GMP Due Diligence

Pharma Plant Acquisition Checklist: 50-Point Due Diligence

Short answer · updated 22 Sep 2026

What a pharma plant acquisition checklist must cover

A pharma plant acquisition checklist tests whether a plant can legally keep running under new ownership and reliably make compliant product. In India, clear four deal-critical checks before spending money on a technical audit:

  1. Licence validity: Form 25/28 permissions match the products, and the five-yearly retention fee is paid.
  2. Deal route: how a change in constitution affects the licence, and whether a fresh licence is needed.
  3. Revised Schedule M: Form A upgradation plan filed, gaps closed, inspection outcome known.
  4. History: inspection observations, NSQ alerts, recalls and open regulatory commitments.

The full checklist below has 50 points across eight areas, ten of them marked deal-critical. Rate each one and the tool scores the plant as you go.

Why a plant tour is not due diligence

Buying a running unit is faster than building one, but you also buy the seller’s compliance history. An equipment list and a walk through the production block will not show a missed retention fee, an upgradation plan that was never filed, or an audit trail that was switched off. Those are the findings that stop production after closing.

The timing matters. The last extended deadline for small and medium manufacturers to meet revised Schedule M ended on 31 December 2025[1], and CDSCO has asked state regulators to plan compliance inspections[2]. A plant that has not upgraded carries a risk the price must reflect.

A fixed checklist makes two plants comparable, gives every finding evidence and a rating, and turns the result into negotiating terms. If you are still at the search stage, start with the verified pharma plants for sale in India.

Licences, ownership and deal route points 1–7 · weight 3

  1. 1

    Manufacturing licences and product permissions

    Deal-critical

    Check Copies of every Form 25 and Form 28 licence, the sections approved, and the product permission list endorsed on each. Match it against what the seller says the plant makes.

    Red flag Products sold from the site that are not on the endorsed list, or sections running that were never approved.

  2. 2

    Licence retention fee status

    Deal-critical

    Check Manufacturing licences now stay valid until suspended or cancelled, provided a retention fee is paid every five years[3]. Ask for the challan for every five-year cycle.

    Red flag A missed retention fee. A late fee of 2% per month runs for up to six months, after which the licence is deemed cancelled[3].

  3. 3

    Deal structure and change in constitution

    Deal-critical

    Check Settle share purchase versus asset transfer with your lawyer before signing. A change in the licensee’s constitution must be intimated, and the existing licence is reported to lapse three months after that intimation[4]. State regulators treat a change of proprietor or partners as a change in constitution needing a fresh licence[5].

    Red flag A closing timetable with no room for the fresh-licence inspection, or a seller who says the licence “transfers automatically”.

  4. 4

    Revised Schedule M status

    Deal-critical

    Check Revised Schedule M (G.S.R. 922(E), 28 Dec 2023) bound large manufacturers after six months. Units with turnover up to ₹250 crore got a conditional extension to 31 Dec 2025 only if they filed a Form A upgradation plan within three months of 11 Feb 2025[1]. Ask for the Form A, the gap assessment and closure evidence. Track status on the Schedule M compliance dashboard.

    Red flag No Form A on record, gaps still open after 31 Dec 2025, or no inspection under the revised Schedule yet. CDSCO asked state regulators in Nov 2025 to plan compliance inspections[2].

  5. 5

    WHO-GMP, COPP and export registrations

    Check WHO-GMP certificate, COPPs issued and product registrations in each export market, with validity dates and dosage forms covered.

    Red flag Expired certificates, or dossiers held by a third party that will not follow the plant.

  6. 6

    Loan licence and contract-manufacturing arrangements

    Check Every loan licensee and third-party customer using the plant: agreements, notice periods and who carries stock, complaints and recalls. See how loan licence placement works.

    Red flag Loan licensees with open NSQ cases or recalls the plant will inherit reputationally.

  7. 7

    Environmental and statutory consents

    Deal-critical

    Check Consent to Establish and Consent to Operate from the State Pollution Control Board (Water Act, 1974; Air Act, 1981), effluent treatment plant performance, hazardous-waste authorisation, fire NOC and factory licence.

    Red flag Expired consents, show-cause notices, or an effluent plant sized for a smaller product mix than you plan to run.

How the score works: each rated point counts Pass = 1, Gap = 0.5, Red flag = 0, weighted by section (licences, history and QC lab ×3; facility, equipment and QMS ×2; people and deal ×1). The weights are Laafon’s editorial judgement, not a regulatory standard. Any red flag on a deal-critical point overrides the percentage.

Share purchase or asset purchase: what happens to the licence

The deal structure decides which licensing route applies, so settle it before the technical audit is scoped. The Drugs and Cosmetics framework does not formally define “change in constitution”; CDSCO’s medical-device FAQs treat a change of more than 50% of voting capital as one, but that definition has not been written into the drugs framework[4]. Confirm the route with your State Licensing Authority.

Turning findings into deal terms

Deal-critical red flags

Make them conditions precedent (for example, the fresh licence granted before closing), specific warranties with indemnities, or an escrow released on proof of closure. If none of those is acceptable to the seller, walk away.

Costed gaps

Price each one and deduct it, or agree who fixes it before closing. Water-system redesign, HVAC rezoning and data-integrity remediation are usually the largest items.

Minor gaps

Move them into a funded 90-day post-closing plan with owners and dates, so findings do not stay in the audit report.

These are common deal mechanisms, not legal advice. Your transaction lawyer decides the drafting.
