Choksi Laboratories Ltd is a contract-testing house - businesses send it samples of what they make or use, and it tells them whether those samples meet quality, safety or regulatory standards. Incorporated in 1993 in Indore, it has grown from a single central laboratory into a five-location network that tests everything from pharmaceutical drugs and food to construction materials and factory emissions. The recurring approach is simple: earn accreditation from the bodies that regulators and export markets trust, then charge a fee for every sample analysed - a model where the certificate is the product.
Business segments
A single engine serving five testing verticals - pharmaceuticals, food and water, environment, construction materials, and calibration - all run from the same laboratory network and the same pool of scientists.
1. Pharmaceutical testing: the regulatory gatekeeper for drug makers
Every batch of medicine needs a certificate before it can be sold, and Choksi Laboratories provides that certificate - its lab is one of the few in India audited by the US FDA.
- Regulatory licences are the entry ticket - the company holds certifications from India's FDA, BIS, and AGMARK, plus NABL accreditation under ISO/IEC 17025, which is internationally recognised through ILAC; without these, no pharmaceutical client can use its reports for compliance.
- Audited by the American regulator - the US FDA inspected the company's facility in September 2019 and issued an Establishment Inspection Report under the "Voluntary Action Indicated" category, a signal to export-focused drug makers that the lab meets global scrutiny.
- Stability testing creates recurring work - beyond one-off batch checks, the company runs long-duration stability and analytical studies for pharmaceutical clients, which means samples arrive steadily over months rather than in single spikes.
- Skilled manpower is the real machinery - with 349 permanent employees as of March 2025, the company's principal asset is its scientists and technicians; losing them to competitors is a risk it manages through continual training and internal audits.
2. Food and water testing: the safety net for what people consume
As FSSAI rules tighten and export markets demand proof of safety, food processors and dairy cooperatives pay Choksi Laboratories to test every batch - and the company is now building a dedicated lab inside a client's own facility.
- Regulatory tailwinds drive volume - rising consumer awareness and stricter FSSAI enforcement mean food businesses must test more frequently, and the company's food and water division has seen increased sample volumes as a direct result.
- Embedded inside the client - in March 2024, the company signed an agreement with Bihar State Milk Co-operative Federation (COMFED) to set up and run a testing laboratory at COMFED's own premises in Patna under the central government's National Programme for Dairy Development, moving from a remote service to an on-site operation.
- Vendor assessment was the company's original innovation - it claims to have been the first in Central India to develop a Vendor Assessment programme for the edible-oil extraction industry, essentially auditing suppliers' quality systems before they ship, which opened the door to long-term food-sector relationships.
3. Environmental testing: the compliance partner for factories and regulators
Every factory needs to prove its emissions and effluent are within legal limits - Choksi Laboratories does that monitoring, and stricter pollution norms mean more samples to test.
- Accredited by pollution control authorities - the company is certified by the Ministry of Environment & Forests and multiple State Pollution Control Boards, so its reports are accepted as evidence of compliance by the very agencies that enforce environmental law.
- Water and soil analysis was an early beachhead - the company states it was the first in Central India to start water and soil analysis services, a line that now feeds into environmental monitoring for industrial clients who must submit regular data to regulators.
- Norm tightening is a demand driver - stricter environmental compliance norms at both national and state levels directly increase the number of tests factories must commission, and the company cites this as a growth engine for the division.
4. Construction material testing: the quality check on buildings before they rise
Real-estate developers and interior-design firms need independent proof that their cement, steel and concrete meet BIS standards - Choksi Laboratories provides it from the same accredited network.
- BIS certification opens the construction vertical - the company's Bureau of Indian Standards accreditation means its test reports on construction materials carry the same weight as government-lab results, which is essential for large infrastructure and real-estate projects.
- Modest but steady demand - the company describes growth in this segment as coming from the real-estate and interior-design industries, suggesting a business that moves with the building cycle rather than racing ahead of it.
5. Calibration services: the invisible backbone of factory quality systems
Every measuring instrument in a factory - from weighing scales to pressure gauges - must be periodically calibrated against a known standard, and Choksi Laboratories does that on-site for companies chasing ISO certification.
- Built for the ISO era - the company claims it was the first in Central India to start instrument calibration services specifically for organisations targeting ISO certification, positioning itself as the partner that makes quality audits passable.
- NABL accreditation makes the certificates portable - because the calibration lab is NABL-accredited under ISO/IEC 17025 and recognised through ILAC, its calibration certificates are accepted internationally, which matters for export-oriented manufacturers whose overseas buyers demand traceable measurements.
- National and international scale - demand for calibration services is driven by the evolving needs of industries operating at national and international scale, meaning the more factories modernise their equipment, the more instruments need checking.
Group structure and partners
A family-run single entity with no subsidiaries - the Choksi family holds board control, runs day-to-day operations, and the company relies on two Indian banks for working capital.
- No holding company, no subsidiaries - Choksi Laboratories operates as a standalone entity with no associates or joint ventures, so all five laboratory locations and all testing verticals sit inside one legal structure.
- Family in the cockpit - the board has four executive directors from the Choksi family, including the Chairman & Managing Director Sunil Choksi, alongside four independent directors; in May 2026, the CFO role shifted from one family director to another as the company took on multiple new projects.
- Two-bank funding base - State Bank of India and HDFC Bank are the company's banking partners, providing working capital limits exceeding five crore rupees secured against current assets, plus foreign-currency loans for equipment imports.
- COMFED is a notable partner - the agreement with Bihar State Milk Co-operative Federation to set up a laboratory inside COMFED's Patna facility represents a shift toward embedded, long-term client partnerships rather than purely transactional sample testing.
