How to Get ISI Certification for a Mineral Water Plant in India: A Comprehensive 2025 Guide
Since 17 October 2024, the ISI mark is no longer mandatory for packaged drinking water (IS 14543) or packaged natural mineral water (IS 13428). FSSAI removed the requirement, and from 1 January 2026 every plant must instead follow FSSAI’s Scheme of Testing. You still need an FSSAI licence to make and sell bottled water. The ISI licence is now voluntary, but many buyers and tenders still ask for it, and the steps below still apply if you choose to get one.
FSSAI’s Scheme of Testing for packaged water (from 1 January 2026)
Plants must test at an FSSAI-notified, NABL-accredited lab:
- Source water: all parameters before use, and again whenever the source changes.
- Microbiological parameters: once a month, including coliforms, Pseudomonas aeruginosa and yeast and mould.
- Selected chemical parameters: once every three months, for example barium, copper, iron, nitrate and aluminium.
- Pesticide residues and all other parameters: once every six months.
- Packaging materials: bottles, jars, caps and pouches, once every six months.
A failure increases the testing frequency, and repeated failures lead to a risk-based FSSAI inspection. Keep the records for at least five years.
In India’s booming beverage industry, where the packaged water market is projected to reach ₹40,000 crores by 2026, launching a mineral water plant isn’t just about sourcing pure water—it’s about proving its safety and quality. The ISI Mark, administered by the Bureau of Indian Standards (BIS), is the gold standard for this, ensuring your product meets rigorous health and safety benchmarks. Without it, your plant risks shutdowns, fines up to ₹5 lakhs, or product seizures under the BIS Act, 2016. At Instacertify, we’ve assisted over 200 mineral water entrepreneurs in securing ISI certification, streamlining the process from setup to compliance.
This detailed guide, updated for October 2025 words and covers everything from standards to challenges. Whether you’re a startup or an expanding producer, we’ll walk you through obtaining ISI certification for your mineral water plant, helping you build consumer trust and tap into India’s health-conscious market. Let’s dive in.
What is ISI Certification for Mineral Water Plants?
The ISI (Indian Standards Institute) Mark is a certification symbol issued by the Bureau of Indian Standards (BIS), India’s national standards body, indicating that a product conforms to specified Indian Standards (IS). For mineral water plants, ISI certification mandates that packaged natural mineral water meets quality, safety, and labeling requirements, which was mandatory for legal production and sale until FSSAI removed the requirement on 17 October 2024. It is now voluntary.Why ISI Certification Matters for Mineral Water
- Consumer Safety: Ensures water is free from contaminants like E. coli, heavy metals, and pesticides. In 2024, BIS reported over 500 cases of non-compliant water products causing health alerts, underscoring the need for verified purity.
- Regulatory Compliance: Under the Food Safety and Standards (Prohibition and Restriction on Sales) Regulations, 2011, all packaged natural mineral water must carry the ISI Mark. Non-compliance leads to penalties or bans.
- Market Credibility: The ISI logo boosts buyer confidence—certified brands see 25-30% higher sales in retail and e-commerce.
- Business Growth: Enables participation in government tenders, exports, and partnerships with hotels/F&B chains.
- Sustainability Edge: Aligns with eco-friendly practices, as standards emphasize minimal chemical use and proper waste management.
Relevant Indian Standard: IS 14542:2024 and IS 13428:2024
Packaged natural mineral water falls under IS 14543:2024 and IS 13428:2024, which specifies requirements for water derived from natural sources (springs, aquifers) without added minerals or treatments beyond disinfection. Key parameters include:- Physical: Turbidity <1 NTU, TDS 50-500 mg/L.
- Chemical: pH 6.5-8.5, no arsenic, lead, or mercury beyond limits.
- Microbiological: Absent coliforms, zero E. coli.
- Radioactive & Pesticide Residues: Strict upper limits.
Who Needs ISI Certification for a Mineral Water Plant?
Until 17 October 2024, ISI certification was mandatory for every unit producing or packaging natural mineral water or packaged drinking water for sale in India. It is now voluntary: plants need an FSSAI licence and must follow FSSAI’s Scheme of Testing, and those who choose the ISI mark follow the BIS steps below.Key Stakeholders

ISI licence fees for packaged drinking water
For plants that choose the ISI mark, BIS charges:
| Fee | Amount |
|---|---|
| Application fee | ₹1,000 |
| Marking fee (IS 14543 and IS 13428) | ₹20 per 1,000 litres for the first 6,000 kilolitres, ₹15 for the next 4,000, ₹10 thereafter |
| Minimum annual marking fee | Lower for micro and small units under the BIS concessions |
| Testing and inspection | Charged at actuals by the BIS-recognised lab and for the factory inspection |
GST applies on top. Confirm the current amounts on the BIS website before you apply; we include them at the published rate in your quote.
In-house lab and equipment list
An ISI licensee must be able to run the routine tests in the BIS scheme of testing and inspection, so BIS expects an in-house lab. Plants without ISI also keep one for daily checks on every batch. A typical setup has:
- a pH meter, conductivity and TDS meter, turbidity meter
- an autoclave, an incubator and a laminar airflow bench for microbiology
- a hot air oven, an analytical balance, a refrigerator and glassware
- media and reagents for coliform, E. coli and yeast and mould tests
The FSSAI-scheme tests listed above are done at an external notified lab, not in-house.
Licences a mineral water plant needs in 2026
- FSSAI licence (State or Central, depending on capacity and turnover)
- Consent to establish and consent to operate from the State Pollution Control Board
- Groundwater abstraction permission from the Central Ground Water Authority or the state authority
- Factory licence and local trade licence
- Plastic EPR registration as a brand owner
- BIS ISI licence, now optional
IS 14543 vs IS 13428
| IS 14543 | IS 13428 | |

What is ISI certification for a mineral water plant?
ISI certification is the Bureau of Indian Standards licence to use the ISI mark on packaged drinking water (IS 14543) or natural mineral water (IS 13428). It was mandatory until 17 October 2024 and is now voluntary; every plant still needs an FSSAI licence and must follow FSSAI’s Scheme of Testing.
What are the primary documents required for ISI certification?
You will need business registration proofs, the factory layout plan, detailed machinery lists, laboratory equipment details, and a recent water test report from an approved laboratory. An FSSAI license is also mandatory to complete the application.
What is the step-by-step process to get this certification?
The process involves submitting an online application on the BIS portal, followed by a detailed factory inspection by officials. Then, product samples are rigorously tested in an approved lab before the final ISI license is officially granted.
How long does the ISI certification process typically take?
Once you submit the complete application and all required documents, the entire certification process generally takes around four to five weeks. However, this timeline heavily depends on how quickly your water samples pass the mandatory laboratory tests.
Is it mandatory to have an in-house testing laboratory?
For an ISI licence, yes: BIS expects a lab that can carry out the routine tests in its scheme of testing and inspection. Without ISI, FSSAI’s Scheme of Testing requires periodic tests at an FSSAI-notified NABL lab, but most plants still keep an in-house lab for daily checks on each batch.
What are the costs involved in obtaining the ISI mark?
The total cost for ISI certification includes the initial application fee, annual license fee, and inspection charges. You must also account for expenses related to setting up the mandatory in-house laboratory and external sample testing fees.
How long is the ISI certification valid for mineral water?
An initial ISI certification for packaged drinking water remains valid for one to two years. Before this period expires, plant owners must apply for renewal and submit production returns to maintain their compliance and uninterrupted market operations.
Which specific BIS standard applies to mineral water plants?
Packaged drinking water must strictly adhere to the IS 14543 standard. However, if your plant specifically processes and bottles natural mineral water, it must comply with the distinct regulations outlined under the IS 13428 certification standard instead.
What is the ISI licence fee for packaged drinking water?
BIS charges an application fee of ₹1,000, a marking fee based on volume (₹20 per 1,000 litres for the first 6,000 kilolitres, then lower), and testing and inspection charges at actuals. GST applies on top, and micro and small units get a concession on the minimum marking fee.
Do I need FSSAI as well as ISI for a water plant?
FSSAI is required; ISI is not. Since October 2024, an FSSAI licence and compliance with FSSAI’s Scheme of Testing are what the law requires, and the ISI mark is voluntary.
