A lot of pharma brands come into the market with high expectations. And honestly, that’s not a bad thing. India is one of the largest pharmaceutical producers in the world, home to some of the most established drug manufacturing companies in India and beyond. The country supplies over 50% of global vaccine demand and about 20% of global generic medicines, according to the Indian Brand Equity Foundation. So the capability is real. The infrastructure is real. The question is whether the specific company you choose can actually deliver what you need.
That gap, between what’s possible and what you actually get, is where most problems start.
What You Should Know First
Working with a drug manufacturing company in India for the first time can feel disorienting, especially if you’re used to working domestically or with European manufacturers.
The communication style is different. The documentation process takes adjustment. And if you walk in without a clear understanding of what certifications to look for or what questions to ask, you can spend weeks in conversations that don’t lead anywhere.
That’s not criticism but just the reality of working across regulatory systems, product categories, and business cultures that don’t always operate the same way.
Certifications Always Come First
Here is why this matters before anything else.
WHO-GMP certification is the baseline standard you should expect from any serious drug manufacturing company in India. It means the facility follows World Health Organisation Good Manufacturing Practices, covering everything from raw material sourcing to final product testing.
If a company cannot produce documentation for WHO-GMP certification, stop the conversation there.
Beyond WHO-GMP, look for:
- GMP certification under Schedule M of the Drugs and Cosmetics Act
- GLP (Good Laboratory Practices) certification for in-house testing
- ISO 9001 certification for quality management systems
- EU GMP or PIC/s auditable infrastructure if you need international market access
These aren’t just badges. They tell you whether a facility runs a controlled, auditable process or whether quality depends on whoever is working that day.
What the Manufacturing Process Actually Looks Like
Once you’ve verified certifications, here is what a standard engagement typically involves.
You share your product requirements, whether that’s a specific formulation, a dosage form like tablets, capsules, oral liquids, or external preparations, and the target therapeutic category. The manufacturer reviews this against their approved formulations and regulatory clearances.
If the product already exists in their portfolio, the process moves faster. If you need a new formulation developed, factor in additional time for R&D, stability testing, and regulatory filing.
After that, you agree on batch sizes, turnaround times, packaging specifications, and labelling requirements. A clear, written agreement covering all of this protects both sides.
One thing worth knowing: manufacturers with flexible minimum order quantities tend to be more partner-oriented. Large MOQ requirements pushed on new clients often signal that the company prioritises volume over relationships.
Do Not See Quality Testing as Optional
Every serious drug manufacturing company in India runs in-house quality control testing before dispatch of the drugs. That includes identity testing, potency testing, dissolution testing for oral solid dosage forms, and stability studies.
Ask specifically what testing happens at each stage: incoming raw materials, in-process checks, and final batch release. A manufacturer that tests only at the end is cutting corners somewhere in the middle.
According to the Central Drugs Standard Control Organisation, all pharmaceutical manufacturers operating in India must comply with Schedule M standards, which cover testing protocols, equipment qualification, and documentation requirements. Any company manufacturing for export also needs to meet the importing country’s regulatory standards.
This is perhaps one of those areas where new clients don’t ask enough questions upfront, and then feel surprised later when they realise not every company tests with the same rigour.
What You Should Know About Turnaround Times and Supply Chain
Be direct about this in your early conversations. Ask for average dispatch timelines after order confirmation. Ask what happens during peak production periods. Ask about buffer stock availability for high-demand products.
A manufacturer with a well-run production schedule will give you specific answers. Vague responses like “we always deliver on time” without any supporting detail are worth probing further.
Supply chain disruptions do happen. API availability fluctuates. Regulatory clearances occasionally cause delays. What separates a good manufacturing partner from a difficult one is how they communicate when things don’t go as planned.
Choosing the Right Partner Takes Time
Here is the honest version of this: there are hundreds of drug manufacturing companies in India, and they are not all operating at the same level.
Some have invested heavily in facilities, certifications, and quality systems. Others are running on older infrastructure and outdated processes.
The ones worth working with will answer your questions directly, share documentation without hesitation, and treat the early conversations like the beginning of a real working relationship.
Take the time to verify what you’re told. Visit the facility if possible. Speak to other brands they manufacture for. That groundwork, done properly at the start, saves a significant amount of time and money later.
