How to Choose a Drug Manufacturing Company in India: 7 Checks (2026)

Every drug manufacturing company in India will tell you it is WHO-GMP certified, quality-focused and customer-centric. All of them. The websites are interchangeable. So the question is not who says the right things — it is what you can actually check before you hand over money and put your brand name on someone else's output.

Here is what to check, in the order that matters. If you want the process first — steps, documents, timelines — read how third-party manufacturing actually works.

1. Ask for the site certificate. Read the table on it.

This is the whole thing, and almost nobody does it. A WHO-GMP certificate is issued to premises, not to a company — the document is literally headed "Site Certificate" and it names an address. Inside it is a table listing the exact dosage forms that site may produce.

So "we are WHO-GMP certified" is not an answer. The answer is: which site, at what address, certified for which forms, under which licence number. Ask for the certificate before you ask for a rate. A company that will send it in ten minutes has nothing to manage. Draw your own conclusion about the ones that cannot.

2. Find out whose licence your product is made under

Plenty of companies offering third-party manufacturing do not own a plant. They take your order and place it with someone else. That is not automatically wrong — but you should know it, because it decides who you can actually call when a batch is late or a batch is wrong.

The licence number is printed on the back of every pack. Ask whose name will be on yours.

3. Check the dosage form matches the certificate

A site certified for tablets, capsules, external preparations and oral liquids cannot legally make your injectable, your eye drop, or your beta-lactam antibiotic. Beta-lactams need physically segregated premises — that is regulation. Ophthalmics and injectables need sterile lines.

If a company offers you every dosage form from one plant, one of you is confused. Ask which site each form comes from.

4. Ask who else that plant manufactures for

A plant that makes stock for one marketing company is inspected by the drug controller and nobody else. A plant manufacturing on contract for other pharmaceutical companies is audited by every one of them — on their schedule, to their standard, with their brand on the strip, and with the power to cancel.

You will never audit a plant yourself. You only need to know who already does.

5. Get the MOQ before the rate

The minimum order quantity decides whether this is viable for you at all. A good per-unit price against a batch you cannot sell inside its shelf life is not a good price — it is dead stock with a nice number on it. Ask for the MOQ first, then the rate, then compare quotes only where composition, quantity, packing and packing-material responsibility all match.

6. Insist on documentation as standard

Batch manufacturing record and certificate of analysis with every batch, automatically — not on request, not as a favour. A manufacturer who hesitates over a COA has told you everything you need to know.

7. Get capacity and timelines in writing

A verbal four weeks is not four weeks. And ask the growth question: what happens to lead time if the order triples? A manufacturer who cannot answer that has not thought about your business, only about this order.

The two lines that settle it

Send these to every manufacturer on your shortlist. Count the replies.

1. Name the site where my products will be manufactured, state your company's relationship to it, and send me the certificate.
2. Which dosage forms in your range are made somewhere else, and where?

Some will not answer. Some will send a brochure. Some will send a certificate — read the company name printed on it and check it against the name on your agreement. The ones who answer both questions in plain language are your shortlist.

Our own answers to both

Vibcare Pharma is a PCD pharma franchise company. It does not manufacture. Manufacturing is done by Vibcare Healthcare Private Limited — a separate company under the same ownership, with its own plant, licences and website.

The site: Khasra No. 6/2/2, Kota Road, Dabkori, Panchkula 134103, Haryana. WHO-GMP certified by the State Drugs Controller-cum-Licensing Authority, FDA Haryana. Site Certificate No. 1/182-1Drug-I-2024, issued 24 October 2024. Licences MLF252023HR000004 and MLF282023HR000005, valid to 7 May 2028.

The forms: tablets, capsules and external preparations — all non beta-lactam — and oral liquids. Four forms. What it does not make: beta-lactam antibiotics, ophthalmics, injectables, softgels, IV liquids, respules, DPI, nasal sprays, protein powders and sachets, and ayurvedic products. Those are made at other WHO-GMP certified sites.

Who else audits it: the plant manufactures on contract for other Indian pharmaceutical companies, whose auditors go through the batch records with the power to cancel a contract.

That is both questions answered before you asked. Ask the rest of your shortlist for theirs.

Not building your own brand? A PCD pharma franchise needs no manufacturer at all — you sell an existing range in a monopoly territory, from ₹25,000. Here is the difference.

Frequently asked questions

How do I choose a drug manufacturing company in India?

Ask for the site certificate before the rate, and read the dosage-form table on it. Confirm whose licence your product will be made under, whether that site is certified for your dosage form, and who else audits the plant. Then get the minimum order quantity before comparing prices.

How can I verify a manufacturer is really WHO-GMP certified?

Ask for the certificate itself, not the claim. It names a specific site and address, carries a certificate number and issuing authority, and lists the exact dosage forms permitted. Cross-check the licence number against the pack. If the licence holder is a different company from the one you are signing with, ask why.

Can a manufacturer make any dosage form at one plant?

No. Beta-lactam antibiotics require physically segregated premises by regulation. Ophthalmics and injectables need sterile lines. Ayurvedic products are licensed under a separate Act. Any company implying one facility covers its entire range is describing something that does not exist — ask which site each form comes from.

What should I ask before signing a manufacturing agreement?

The minimum order quantity, the lead time in writing, what happens to lead time if the order triples, whether batch manufacturing records and certificates of analysis come as standard, and who carries liability for rejected or damaged material. Read the liability clause before signing, not after.
