Medical Device Cleanrooms in India: Risk Classes, ISO Grades and Space Options
Cleanroom space for medical device manufacturing depends on two things: your device’s risk class and whether it is sold sterile. A non-sterile, low-risk device may need little more than a clean, controlled assembly area. A sterile implant needs classified cleanrooms, validated sterilisation and a quality system the regulator will inspect. Most device makers also need precision machining and metrology space, and that has very different rules of its own.
Which rules apply to device makers in India?
Medical devices are regulated under the Medical Devices Rules, 2017, which sort devices into four risk classes: A (lowest risk), B, C and D (highest risk). Licensing became mandatory for Class A and B devices from 1 October 2022, and for Class C and D from 1 October 2023.
The class matters for your building because it decides who inspects you. Class C and D manufacturing licences come from the Central Licensing Authority, and CDSCO inspects the site against the Fifth Schedule, the quality management system requirements in the rules. Those closely follow ISO 13485, the international standard for device quality systems. State licensing authorities handle Class A and B.
Put simply: the higher your class, the more your facility will be looked at, and the more your records need to show it is under control.
What spaces does a device facility need?
| Area | What happens there | What to get right |
|---|---|---|
| Machining and fabrication | CNC machining, moulding, laser cutting | Heavy power, floor loading, coolant and swarf kept well away from clean areas |
| Metrology room | Measuring parts against drawings | Temperature control around 20°C, low vibration, stable humidity |
| Cleaning and passivation | Parts cleaned before entering clean areas | Purified water, chemical handling, drainage |
| Cleanroom assembly | Assembly of sterile or sensitive devices | ISO-classified cleanroom, gowning room, pressure control |
| Packaging | Sealing devices into sterile barrier packaging | Usually inside or next to the cleanroom, validated sealing equipment |
| Sterilisation | Ethylene oxide, gamma or e-beam | Often outsourced; on-site EtO needs specialist ventilation and safety |
| Testing and QC | Mechanical, electrical and biocompatibility testing | Separate lab space, calibrated equipment |
The metrology room is a quiet detail that trips people up. ISO 1 sets 20°C as the standard reference temperature for dimensional measurement. A room that drifts a few degrees through the day will make a perfectly good part fail inspection, and you will waste days hunting a problem that is really the air conditioning.
How clean does a device cleanroom need to be?
Cleanroom cleanliness is classified under ISO 14644-1, by how many airborne particles a room allows. Many sterile device assembly and packaging operations run in ISO 7 or ISO 8 rooms, with cleaner ISO 5 zones for any critical open steps. Your risk assessment and sterilisation method decide the final answer, not a rule of thumb.
The common mistake is the opposite one: building a cleaner room than you need. Every step up in cleanliness costs more to build, more to run, and more to keep validated.
Where are device makers setting up?
Visakhapatnam has the clearest offer for device makers. The Andhra Pradesh MedTech Zone (AMTZ) is a 270-acre state-owned park with shared testing labs, a gamma irradiation centre and prototyping facilities, so smaller companies do not have to build all of it themselves. Hyderabad and Bengaluru suit device companies that lean heavily on electronics, software or a larger engineering workforce.
What should you check before choosing space?
- Risk class of your devices, and who will inspect you
- Cleanroom grade needed, set by risk assessment, not habit
- Clear separation between machining and clean areas
- A temperature-stable, low-vibration metrology room
- Purified water for cleaning, if your process needs it
- Sterilisation route: in-house, contract or nearby shared facility
- Room to add lines as your product range grows
How does a medtech campus help?
Starting near shared testing and sterilisation cuts both cost and time. So does moving into a building where power, HVAC and environmental monitoring are already running.
NQF Hubs (NXT QST FWD) operates Medpolis, a 20-acre medtech campus in Visakhapatnam that combines early-stage incubation with production space, and offers build-outs and campus operations across its sites, as set out on its Solutions page. Our guide to lab and cleanroom build-out timelines explains the stages from design to qualification, and our comparison of Hyderabad, Bengaluru and Visakhapatnam helps with choosing a cluster.
Frequently Asked Questions
What facilities does an agri-biotech startup need in India?
Most start with a wet lab for molecular biology and plant tissue culture, plus growth chambers. As work progresses, they need greenhouse access, containment if they handle genetically modified material, and fermentation capacity for biological inputs.
Do genome-edited crops need containment greenhouses in India?
Genome-edited plants made with SDN-1 and SDN-2 techniques, which add no foreign DNA, were exempted from India’s genetically modified crop rules in 2022. Plants carrying foreign DNA still go through biosafety approvals and are typically grown in containment until cleared.
What is a containment greenhouse?
It is a greenhouse designed to stop pollen, seeds and organisms escaping, using screening or sealed glazing, controlled drainage and restricted entry. It is used for regulated plant research before field trials are approved.
Where can I make biofertilisers at pilot scale in India?
You need a facility with fermenters, steam, cooling water and effluent treatment, plus pollution control consent. Options include shared public facilities such as BioE3 biomanufacturing hubs, or leased pilot space on a science campus.
What approvals do animal health labs need in India?
Labs working with pathogens need biosafety approvals matched to their containment level. Any animal studies need a facility registered with CPCSEA, and veterinary vaccines need GMP manufacturing and product licensing.

Frequently asked questions
Do all medical devices need a cleanroom in India?
No. Cleanrooms are mainly needed for sterile, implantable or contamination-sensitive devices. Many low-risk, non-sterile devices can be made in clean, controlled assembly areas.
What cleanroom class is used for medical devices?
Many sterile device assembly and packaging lines use ISO 7 or ISO 8 cleanrooms, with ISO 5 zones for critical open steps. The final grade comes from your risk assessment.
Who licenses medical device manufacturing in India?
Class C and D devices are licensed by the Central Licensing Authority after a CDSCO inspection. Class A and B devices are licensed by state licensing authorities.
What is AMTZ?
AMTZ (Andhra Pradesh MedTech Zone) is a 270-acre medical device park in Visakhapatnam, owned by the Andhra Pradesh government, with shared testing, sterilisation and prototyping facilities.
