Ask anyone who runs a pharmaceutical manufacturing unit in India what keeps them up at night, and GMP compliance is usually somewhere near the top of the list. It's not optional paperwork you can push to next quarter. If you make drugs in India, Schedule M compliance is the law, and if you want to sell those drugs beyond Indian borders, a WHO-GMP certificate is often the thing standing between you and a signed export contract.
This page breaks down what WHO-GMP certification actually covers, how it connects to India's own Schedule M rules, what you'll need to apply, and what the process looks like from start to finish.
WHO-GMP stands for World Health Organisation Good Manufacturing Practice. It's essentially a stamp confirming that your manufacturing facility, your processes, and your quality systems meet the standards laid out in the WHO's Technical Report Series, mainly TRS 986, Annex 2, along with the validation guidance in Annex 3.
In plain terms, it tells a buyer in another country that your products aren't just made, they're made under controlled, documented, repeatable conditions where quality isn't left to chance. Around a hundred countries recognise WHO-GMP as a baseline for allowing pharmaceutical imports, which is exactly why exporters chase it so hard.
Here's where people usually get confused, so let's untangle it. Schedule M, under the Drugs and Cosmetics Rules, 1945, is the mandatory GMP standard every licensed drug manufacturer in India has to follow. It isn't a choice. If your facility doesn't meet Schedule M, you don't get to keep your manufacturing licence, full stop.
The Revised Schedule M, which came into force for larger manufacturers from mid-2024 (smaller units got extra time, till the end of 2025), pushed Indian norms much closer to WHO-GMP anyway. It brought in requirements around a proper Pharmaceutical Quality System, quality risk management, and far more rigorous equipment qualification and validation than the older rulebook asked for.
So where does WHO-GMP certification come in if Schedule M is already mandatory? Think of it this way: Schedule M compliance keeps your licence alive domestically. A WHO-GMP certificate is the internationally recognised proof of that same compliance, something a foreign buyer, regulator, or tender committee can actually verify and trust without having to understand India's domestic drug law.
Two layers handle it. The Central Drugs Standard Control Organisation, under the Ministry of Health and Family Welfare, sets the national policy and coordinates on export-related certification. On the ground, though, it's your State Drug Control Department or State FDA that actually inspects your facility, issues your manufacturing licence (Form 25 or Form 28), and grants the WHO-GMP certificate once you clear inspection.
If you fall into any of these categories, WHO-GMP certification is worth pursuing, and in some cases you won't get far without it:
The document list can look intimidating at first glance, but most of it is stuff a properly run manufacturing unit should already have on file:
If any of these are missing or outdated, that's usually the first thing a consultant will flag before you even think about applying, because an incomplete quality system is the most common reason inspections get delayed.
First, you get your documentation in order. This is the part people underestimate. A gap analysis against Schedule M and WHO TRS 986 before you formally apply saves a lot of grief later.
Then you submit your application to the State Drug Control Department along with your manufacturing licence details and quality documentation.
An inspection gets scheduled. A team from the drug control department visits your facility and goes through everything — your production areas, your QC lab, your water system, storage conditions, documentation practices, the works. They'll pull batch records and cross-check them against your SOPs.
If gaps show up, you fix them. Maybe your validation records are incomplete, or a piece of equipment hasn't been properly qualified. You'll get an inspection report listing what needs correcting, and you'll need to close those out with evidence before certification proceeds.
Once you clear inspection, the certificate is issued. You now have a WHO-GMP certificate tied to your specific manufacturing licence and product categories, which you can present to overseas buyers, regulators, or tender authorities.
And it doesn't stop there. Periodic re-inspections keep your certification current, and any major change to your facility, equipment, or product range usually needs to be reported and, in some cases, re-verified.
Costs depend heavily on your facility size, how many product categories you want covered, and how much remediation work is needed before you're inspection-ready. A small single-product unit with reasonably good documentation will spend far less than a multi-line manufacturer chasing certification across several dosage forms.
Validity generally runs between one and three years, though manufacturing licences themselves are often granted with ongoing validity subject to retention fees and continued compliance, rather than a hard expiry. Either way, renewal or re-inspection is standard practice, and it's smart to start that conversation well before anything lapses rather than after a buyer asks for a certificate that's already expired.
For a facility that's already running close to Schedule M standards, certification can move fairly quickly, sometimes within a couple of months. If there's real remediation work involved — new equipment to qualify, validation studies to complete, documentation systems to rebuild — it can stretch to several months. The honest answer is that it depends far more on how ready your facility actually is than on how fast the paperwork moves.
Market access, mostly. A huge chunk of the world simply won't buy pharmaceutical products without some form of GMP proof, and WHO-GMP happens to be the version most widely recognised across roughly a hundred countries. It also tends to tighten up internal processes — batch failures and deviations usually drop once a proper quality system is actually being followed rather than just documented on paper. And there's a credibility angle too. A certified facility has an easier time in tender processes, distributor negotiations, and due diligence conversations with international partners who'd otherwise have no easy way to verify your quality standards.
Getting WHO-GMP certified isn't just about filling forms, it's about making sure your documentation, validation records, and facility actually hold up under inspection. At Legal Dev, we work with pharmaceutical manufacturers across India to run a proper gap analysis first, fix what needs fixing, and then take you through the application and state drug controller audit without the usual back and forth.
Whether you're preparing for your first WHO-GMP certificate or renewing an existing one, our team can manage the documentation, coordinate the inspection process, and keep things moving so you're not stuck waiting on a buyer who's waiting on you.
It's certification confirming that a pharmaceutical manufacturing facility meets the World Health Organisation's Good Manufacturing Practice standards, covering everything from raw material handling to finished product release.
Not WHO-GMP specifically, no. What's mandatory is Schedule M compliance under the Drugs and Cosmetics Act. WHO-GMP is the internationally recognised certificate that demonstrates that same level of compliance to overseas buyers and regulators.
Your manufacturing licence (Form 25/28) is the legal permission to produce drugs in India. WHO-GMP certification is proof, recognised abroad, that your facility runs to a globally accepted quality standard. You generally need the licence before certification even becomes possible.
It varies a lot. A facility that's already close to compliant might get through it in a couple of months. One that needs real remediation, new validations, documentation overhauls, could take considerably longer.
Yes. Size doesn't disqualify anyone. What matters is whether the facility and its quality systems meet the required standards, not how big the operation is.
A properly documented quality management system, qualified technical staff, validated equipment and processes, and consistent adherence to good manufacturing practices across the board.
Typically one to three years, after which a fresh inspection or renewal process is needed to keep it current.
No. Ayurvedic, Siddha, Unani, and homeopathic manufacturers pursue GMP alignment too, and medical device or nutraceutical companies often need to show similar proof for export markets even where it isn't strictly mandated.
Get in touch with Legal Dev today and we'll run the gap analysis, fix what needs fixing, and take you through the audit without the back and forth.
