BIS ISI License for Packaged Drinking Water Plant India: Step-by-Step Guide 2026
If you're setting up a BIS ISI license packaged drinking water plant India , you need to understand one thing before anything else: you cannot sell a single bottle without this certification. Under the Bureau of Indian Standards (Compulsory Registration) Order, any packaged drinking water sold commercially in India must carry the ISI mark. No mark, no legal sale — regardless of how clean your water actually is.
The process is structured, not random. There's a defined sequence, a checklist of documents, a mandatory inspection, and lab tests. What trips most first-time applicants isn't the inspection itself — it's arriving for inspection with machinery or documentation that doesn't match BIS requirements. This guide covers the full process so you don't have that problem.

Why the BIS ISI License Is Non-Negotiable for Water Businesses
Packaged drinking water is classified as a food product under Indian law. That means it sits under two regulatory frameworks simultaneously — the Food Safety and Standards Act (FSSAI) and the BIS Act. Both apply to you whether you're selling 500 ml bottles or 20-litre jars.
The BIS certification specifically addresses water quality. IS 14543 sets the permissible limits for physical, chemical, and microbiological parameters. Before you get the ISI mark, BIS verifies not just your water quality, but the entire treatment and bottling process that produces it. That's why your machinery choices matter as much as your water source.
The full regulatory framework for packaged drinking water is maintained by the Bureau of Indian Standards. You can access the official BIS Compulsory Certification portal and FSSAI's licensing portal for the current fee schedules and updated standards documentation.
Understanding IS 14543 vs IS 13428
Two BIS standards apply to bottled water in India. Most entrepreneurs confuse them, and applying under the wrong one wastes months. Here's the plain difference:
| Parameter | IS 14543 — Packaged Drinking Water | IS 13428 — Natural Mineral Water |
|---|---|---|
| Water Source | Any treated source (borewell, municipal, etc.) | Certified natural underground spring only |
| Purification | RO + UV / Ozone treatment mandatory | Limited treatment — source purity relied upon |
| Minimum TDS | No minimum specified | 250 mg/L minimum |
| Who Applies | Most new water businesses | Premium / specialty segment only |
| Entry Cost | Lower — any compliant source works | Higher — source certification required first |
| Market Size | Mainstream retail, HoReCa, institutions | Premium retail, export |
| ISI Mark Required | Yes — mandatory | Yes — mandatory |
Unless you have a certified natural spring with geological documentation, you're applying under IS 14543. That's the route for 95% of new water businesses in India. The rest of this guide focuses on IS 14543 for packaged drinking water.
Step-by-Step BIS ISI Certification Process for a Packaged Drinking Water Plant India
The IS 14543 certification process isn't fast — expect 90 to 120 days from application to license grant if everything goes cleanly. The honest caveat: most delays happen not because BIS is slow, but because applicants submit incomplete documents or show up to inspection with non-compliant equipment. Work through each step methodically.
-
1Choose Your Standard and Get Water Tested
Confirm you're applying under IS 14543. Get your source water tested at an NABL-accredited laboratory. The report must show results against all IS 14543 parameters. This report is submitted with your application and must be current (not older than three months at the time of submission).
-
2Set Up a BIS-Compliant Plant and Production Line
Your plant must meet specific requirements. All water-contact surfaces must be food-grade SS316L stainless steel as a minimum. Your RO system, UV steriliser, ozone generator, filling machine, and capping unit must be operational and properly installed — not just present on site. BIS inspectors verify actual functionality.
-
3Obtain FSSAI Registration or License
FSSAI registration (for smaller operations) or a State/Central FSSAI license (depending on turnover and distribution) is a prerequisite for your BIS application. Get this first. FSSAI and BIS are separate — you need both. Your FSSAI registration number goes on your label.
-
4Prepare Your Document Package
You'll need: business registration documents (GST, MSME, trade license), plant layout drawing with machine positions, a complete list of machinery with specifications, source water NABL test report, quality control protocol document (SOP for production), NOC from the local authority or municipal body, and proof of land / premises ownership or lease.
-
5Submit Application Online at bis.gov.in
Applications are submitted through the BIS portal. You'll select the relevant product standard (IS 14543), fill in factory details, upload all documents, and pay the application fee. Keep copies of everything — the portal reference number is your tracking ID.
-
6Factory Inspection by BIS Officer
BIS schedules an inspection at your plant. The officer verifies your machinery, production process, quality control setup, and storage conditions. They'll also collect water samples during this visit for independent lab testing. Make sure your entire line is running the day of inspection — not just set up.
-
7Water Sample Testing at BIS / NABL Lab
The samples collected during inspection are tested against all IS 14543 parameters. If the results pass, you move to the grant stage. If any parameter fails, you'll need to address the issue, get fresh water tested, and potentially go through another inspection. This is why your RO and treatment system must be correctly sized and operational from day one.
-
8Grant of License and CM/L Number
Once inspection and tests clear, BIS issues your license with a unique CM/L (Certification Mark/License) number. This number must appear on every bottle label alongside the ISI mark. You can now legally sell packaged drinking water commercially across India.
BIS certification isn't a one-time exercise. Expect annual surveillance visits where BIS re-inspects your plant and retests water samples. Keep your quality records, production logs, and machinery maintenance documents up to date at all times. Surveillance is unannounced in some cases.
FSSAI License for Water Plant India — What's Different
The FSSAI license for water plant India is a separate requirement under the Food Safety and Standards Act 2006. While BIS certifies your product quality against the IS standard, FSSAI licenses your business as a food manufacturer.
Which FSSAI category applies to you:
| Annual Turnover | FSSAI Type | Issuing Authority | Approx. Fee |
|---|---|---|---|
| Up to ₹12 Lakh | Basic Registration | Local authority | ₹100/year |
| ₹12 Lakh — ₹20 Crore | State License | State Commissioner | ₹2,000 — ₹5,000/year |
| Above ₹20 Crore or interstate / export | Central License | FSSAI, Delhi | ₹7,500/year |
One practical note: your FSSAI license number, along with your BIS CM/L number, must both appear on your bottle label under the mandatory labelling requirements of IS 14543. Plan your label design to include both before production starts.

Machinery That BIS Inspectors Actually Check
This is where many new plant owners underestimate the preparation needed. BIS inspection isn't just a document review — the officer physically walks through your production line and checks that each stage of treatment and bottling is functional and compliant with packaged drinking water compliance India requirements.
Here's what gets scrutinised on inspection day and how Aim Technologies' equipment meets each requirement:
Pressure sand filter · Activated carbon · MCF · RO system · UV steriliser · Ozone generator · Product storage tank
SS316L contact parts · Mono block rotary · No-bottle-no-fill sensor · Separate cap elevator
2 KVT to 6 KVT models · Max volume 1500 ML · Food-grade preform processing
The IS 14543 standard requires that all surfaces in contact with treated water — storage tanks, pipelines, filling nozzles, caps — must be made of food-grade material. For metal surfaces, SS316L is the accepted standard. Aim Technologies' filling machines use SS316L for all water-contact parts as a standard specification.
Common Mistakes That Delay BIS Certification for Water Plants
Most first-time applicants face delays that were entirely preventable. Here are the mistakes that come up repeatedly in the BIS certification water bottling plant process:
Missing even one document — like the NABL water test report or the quality control SOP — gets your application returned. BIS doesn't process partial applications. Go through the checklist systematically before you submit.
If your filling nozzles, storage tanks, or pipelines use SS304 or non-food-grade materials for water-contact surfaces, the inspector will flag it. Retrofitting after inspection causes weeks of delay. Specify SS316L when ordering your machinery.
BIS inspectors expect to see your line running — not just installed. If your filling machine is present but not commissioned, or your ozone generator is "being installed," the inspection will not conclude successfully. Complete commissioning and trial runs before your inspection date.
They're separate applications, separate fees, separate authorities. Starting your BIS application before you have FSSAI registration means you'll need to return and amend your BIS paperwork. Get FSSAI first.
Your bottle label must show: ISI mark with CM/L number, FSSAI number, product name, source water type, volume, MFG date, expiry, batch number, and manufacturer address. Designing this after you have the license is smart — but you need to know what space it requires on your bottle before your mould is final.
Who Should Consider the ISI Mark Water Business Route?
Not every packaged drinking water business looks the same. Here's a quick way to check which path makes sense for where you are right now.
- A borewell, municipal, or other treated water source
- Budget for a complete RO + UV + ozone treatment line
- Plant space for a compliant production floor
- Plans to sell in retail, HoReCa, or institutional markets
- FSSAI registration already in hand or in process
- A label design with all mandatory fields planned
- NABL-accredited water test report (not older than 3 months)
- Full plant layout drawing with machine positions
- Machinery spec sheets from your supplier
- Quality control SOP document for production
- NOC from local authority or municipal body
- Commissioned and running production line for inspection
Entrepreneurs starting a packaged drinking water compliance India business for the first time, and existing water plants adding a new production unit. If you're expanding capacity, your existing CM/L number covers the new unit only after BIS re-inspection of the expanded facility. Plan that into your timeline.
