📋 WHO-GMP vs Indian Schedule M: What’s the Difference?
India’s domestic GMP regulations are codified in Schedule M of the Drugs and Cosmetics Rules, 1945. In 2023, the CDSCO revised Schedule M to align more closely with WHO-GMP standards — this revised Schedule M (sometimes referred to as “Schedule M II”) requires:
- A formal Quality Management System (QMS) with documented procedures
- Risk-based approach to manufacturing and quality control
- Personnel training and qualification records
- Premises and equipment qualification (IQ/OQ/PQ)
- Validated cleaning procedures and change control systems
- Internal audit and management review processes
A manufacturer that is fully compliant with the revised Schedule M is essentially operating at WHO-GMP levels. However, WHO-GMP certification itself is a formal designation — it means an authorized inspection body has verified compliance. Schedule M compliance without certification is self-declared.
⚠️ Red Flags: What to Watch For
Be cautious if you encounter any of these warning signs:
- Certificate that looks unofficial: Poor print quality, missing official seal or signature, no certificate number, or issued by an unrecognized body.
- Expired certificate presented as valid: The date on the certificate is clearly past the validity period.
- Scope mismatch: The certificate covers a product category that does not include what you’re buying — a manufacturer certified for Ayurvedic products is not automatically certified for allopathic generics.
- Refusal to share: A legitimate manufacturer with nothing to hide should have no problem sharing a current GMP certificate.
- Certificate from an obscure “certification body”: Legitimate GMP certification comes from national regulatory authorities or WHO-prequalified inspectorates. Certificates from unknown third-party “consultancies” are not equivalent to regulatory GMP certification.
💡 Practical Quick Checklist
Before placing a bulk order for Indian generic medicines, run through this quick checklist:
- Ask for the current WHO-GMP or Schedule M GMP certificate from the manufacturer
- Verify the certificate number and issuing authority
- Check the certificate’s validity date — is it still in force?
- Confirm the scope covers the product you are buying
- Cross-check the manufacturer name on the CDSCO portal (cdsco.gov.in)
- For WHO-prequalified products, verify on WHO’s prequalification database
- Look for any CDSCO drug alert notices or regulatory actions against the manufacturer
- Prefer purchasing through verified distribution channels — see IMSDA’s verified member directory

Step 4: Confirm the certificate is current
GMP certificates have validity periods. Most are issued for 1–3 years and require re-inspection before renewal. A certificate that expired six months ago is not valid — even if the manufacturer “technically still complies.”
Ask specifically:
- When was the last GMP inspection?
- Is the certificate still within its validity period?
- Has the manufacturer received any critical or major observations during the most recent inspection?

📦 Why WHO-GMP Matters for Buyers
WHO-GMP certification tells you several things about a manufacturer:
- Quality systems are in place: The manufacturer has documented procedures for every stage of production — from raw material receipt to finished product release.
- Facilities meet minimum standards: Premises, equipment, and personnel qualifications are inspected and found adequate.
- Regulatory oversight: The certification is issued by a national regulatory authority (in India, the CDSCO or a state drug control authority) after a formal inspection — it is not self-declared.
- Export eligibility: Many regulated and semi-regulated markets require WHO-GMP or an equivalent GMP standard for imported pharmaceutical products.

🎯 What Is WHO-GMP?
WHO-GMP stands for World Health Organization — Good Manufacturing Practice. It is an international standard that specifies the minimum requirements for the methods, facilities, and controls used in the manufacturing, processing, and packaging of pharmaceutical products.
The WHO-GMP guidelines are documented in the WHO Technical Report Series (TRS), most recently updated in the WHO TRS 996 (2016) Annex 2, which provides a comprehensive framework for GMP for pharmaceutical products. These guidelines are used by WHO member states as the basis for their own national GMP regulations — and many countries, including India, have aligned their domestic GMP standards with WHO-GMP.

However, WHO-GMP certification itself is a formal designation — it means an authorized inspection body has verified compliance. Schedule M compliance without certification is self-declared.
⚠️ Red Flags: What to Watch For
Be cautious if you encounter any of these warning signs:
- Certificate that looks unofficial: Poor print quality, missing official seal or signature, no certificate number, or issued by an unrecognized body.
- Expired certificate presented as valid: The date on the certificate is clearly past the validity period.
- Scope mismatch: The certificate covers a product category that does not include what you’re buying — a manufacturer certified for Ayurvedic products is not automatically certified for allopathic generics.
- Refusal to share: A legitimate manufacturer with nothing to hide should have no problem sharing a current GMP certificate.
- Certificate from an obscure “certification body”: Legitimate GMP certification comes from national regulatory authorities or WHO-prequalified inspectorates. Certificates from unknown third-party “consultancies” are not equivalent to regulatory GMP certification.
💡 Practical Quick Checklist
Before placing a bulk order for Indian generic medicines, run through this quick checklist:
- Ask for the current WHO-GMP or Schedule M GMP certificate from the manufacturer
- Verify the certificate number and issuing authority
- Check the certificate’s validity date — is it still in force?
- Confirm the scope covers the product you are buying
- Cross-check the manufacturer name on the CDSCO portal (cdsco.gov.in)
- For WHO-prequalified products, verify on WHO’s prequalification database
- Look for any CDSCO drug alert notices or regulatory actions against the manufacturer
- Prefer purchasing through verified distribution channels — see IMSDA’s verified member directory

When you’re sourcing generic medicines from India — whether you’re a hospital procurement officer, a retail pharmacy, or an international buyer — one of the most important quality markers you can check is WHO-GMP certification. But what exactly does it mean, how do you verify it, and what are its limits? This guide walks you through the practical steps.
🎯 What Is WHO-GMP?
WHO-GMP stands for World Health Organization — Good Manufacturing Practice. It is an international standard that specifies the minimum requirements for the methods, facilities, and controls used in the manufacturing, processing, and packaging of pharmaceutical products.
The WHO-GMP guidelines are documented in the WHO Technical Report Series (TRS), most recently updated in the WHO TRS 996 (2016) Annex 2, which provides a comprehensive framework for GMP for pharmaceutical products. These guidelines are used by WHO member states as the basis for their own national GMP regulations — and many countries, including India, have aligned their domestic GMP standards with WHO-GMP.
📦 Why WHO-GMP Matters for Buyers
WHO-GMP certification tells you several things about a manufacturer:
- Quality systems are in place: The manufacturer has documented procedures for every stage of production — from raw material receipt to finished product release.
- Facilities meet minimum standards: Premises, equipment, and personnel qualifications are inspected and found adequate.
- Regulatory oversight: The certification is issued by a national regulatory authority (in India, the CDSCO or a state drug control authority) after a formal inspection — it is not self-declared.
- Export eligibility: Many regulated and semi-regulated markets require WHO-GMP or an equivalent GMP standard for imported pharmaceutical products.
🔍 How to Verify a WHO-GMP Certificate
Verification requires checking the certificate itself and the issuing authority. Here’s a step-by-step approach:
Step 1: Ask for the certificate
Request a copy of the manufacturer’s current WHO-GMP certificate. A legitimate manufacturer should be able to provide this without hesitation. The certificate should show:
- Manufacturer’s registered legal name and address
- Certificate number and issue date
- Expiry date or the “valid until next inspection” date
- Scope of certification — which products or product categories are covered
- Name of the issuing authority (e.g., CDSCO, state FDA, or a WHO-prequalified inspectorate)
Step 2: Check the issuing authority
In India, GMP certification is issued by the Central Drugs Standard Control Organisation (CDSCO) or by state drug control authorities. The CDSCO conducts inspections of manufacturing facilities and issues GMP certificates under the Drugs and Cosmetics Act, 1940 and Rules, 1945.
You can cross-check the manufacturer against the CDSCO’s online resources at cdsco.gov.in. Look for:
- Manufacturer licensing status on the CDSCO portal
- Any public notices, advisories, or regulatory actions involving the manufacturer
Step 3: Check WHO prequalification (if applicable)
For certain essential medicines, the WHO maintains a prequalification list of manufacturers whose products meet WHO quality standards. Prequalification goes beyond GMP — it includes an assessment of product quality, safety, and efficacy. You can check the WHO prequalification database at extranet.who.int/prequal.
WHO prequalification is especially relevant for:
- Vaccines and biological products
- Antiretrovirals (HIV medicines)
- Tuberculosis and malaria treatments
- Essential medicines on the WHO Model List
Step 4: Confirm the certificate is current
GMP certificates have validity periods. Most are issued for 1–3 years and require re-inspection before renewal. A certificate that expired six months ago is not valid — even if the manufacturer “technically still complies.”
Ask specifically:
- When was the last GMP inspection?
- Is the certificate still within its validity period?
- Has the manufacturer received any critical or major observations during the most recent inspection?
📋 WHO-GMP vs Indian Schedule M: What’s the Difference?
India’s domestic GMP regulations are codified in Schedule M of the Drugs and Cosmetics Rules, 1945. In 2023, the CDSCO revised Schedule M to align more closely with WHO-GMP standards — this revised Schedule M (sometimes referred to as “Schedule M II”) requires:
- A formal Quality Management System (QMS) with documented procedures
- Risk-based approach to manufacturing and quality control
- Personnel training and qualification records
- Premises and equipment qualification (IQ/OQ/PQ)
- Validated cleaning procedures and change control systems
- Internal audit and management review processes
A manufacturer that is fully compliant with the revised Schedule M is essentially operating at WHO-GMP levels. However, WHO-GMP certification itself is a formal designation — it means an authorized inspection body has verified compliance. Schedule M compliance without certification is self-declared.
⚠️ Red Flags: What to Watch For
Be cautious if you encounter any of these warning signs:
