BIS IS 14543 vs IS 13428: Packaged Drinking Water vs Natural Mineral Water Plant Setup & License Guide

Water Business Industry Guide

Operating a legally compliant commercial bottled water enterprise in India requires obtaining mandatory certification from the Bureau of Indian Standards (BIS). However, many new entrepreneurs confuse the two fundamental standards: IS 14543 for Packaged Drinking Water (Other than Packaged Natural Mineral Water) and IS 13428 for Packaged Natural Mineral Water. Understanding their engineering, legal, and operational differences is crucial before investing capital.

1. Direct Technical Comparison: IS 14543 vs IS 13428

Parameter IS 14543 (Packaged Drinking Water) IS 13428 (Natural Mineral Water)
Source Water Any potable water source (borewell, river, municipal tap) Designated natural subterranean spring or artesian well only
Permitted Purification Reverse Osmosis (RO), demineralization, remineralization allowed Physical filtration (micron/sand) only; NO RO, NO chemical alteration
Total Dissolved Solids (TDS) 75 to 500 mg/L 150 to 700+ mg/L naturally occurring
Mandatory Minerals Calcium (min 20 mg/L), Magnesium (min 10 mg/L) Must contain naturally balanced minerals; no external dosing
Packaging Medium PET bottles, 20L PC jars, pouches (where state permits) Premium glass bottles, BPA-free PET, sealed at natural source
Target Market Mass retail (₹10–20/bottle), offices, households, catering Luxury hotels, fine dining, upscale supermarkets (₹60–150/bottle)

2. Mandatory Testing Laboratory Equipment Checklist

Both standards legally mandate setting up an in-house chemical and microbiological testing laboratory operated by qualified chemists and microbiologists approved by the BIS audit team:

  • Microbiology Equipment: Laminar Air Flow (LAF) Class 100 workbench, double-walled vertical autoclave, bacteriological incubator (37°C), BOD incubator (20–22°C), colony counter, compound microscope, and hot air sterilizing oven.
  • Chemical Testing Equipment: Precision analytical electronic balance (0.0001g), digital pH meter with ATC probe, conductivity meter, nephelo-turbidity meter, Nessler cylinders for ammonia/nitrate testing, and titration burettes.
  • Glassware & Reagents: Petri dishes, conical flasks, membrane filter funnels, nutrient agar, m-Endo broth, Kovac's reagent, and standard buffer solutions with NABL calibration certificates.

3. BIS Licensing Roadmap & Step-by-Step Procedure

  1. Step 1 - Factory & Lab Erection: Complete civil building construction, Class 10,000 bottling cleanroom, and in-house laboratory equipment setup.
  2. Step 2 - Online Portal Application: Register on the BIS Manakonline portal, submit Form-V, industrial layout diagrams, and machinery test certificates.
  3. Step 3 - Preliminary Factory Audit: BIS quality inspecting officers visit the factory, inspect hygiene zoning, verify chemist qualifications, and witness trial production.
  4. Step 4 - Sample Sealing & Independent NABL Testing: Auditors draw two sealed batches of water samples for 30-day comprehensive chemical, pesticide residue, and heavy metal testing at an accredited government NABL laboratory.
  5. Step 5 - Grant of ISI Mark License: Upon successful sample clearance, the Bureau of Indian Standards issues the official CM/L (Certification Marks/License) number.

4. Frequently Asked Questions

Can I sell packaged drinking water without a BIS ISI license in India?

No. Under the Food Safety and Standards Act (FSSAI) and Bureau of Indian Standards Act, selling packaged drinking water without a valid BIS ISI certification is a non-bailable offense leading to factory closure, seizure of goods, and severe financial penalties.

What is the difference between IS 14543 and IS 13428?

IS 14543 applies to Packaged Drinking Water where water from borewells or municipal lines is purified using Reverse Osmosis (RO) and remineralized. IS 13428 applies to Natural Mineral Water which must originate from a protected underground spring, bottled at source without changing its natural mineral composition.

How long does it take to obtain a BIS license for a water plant?

The standard timeline is typically 45 to 90 days from the date of online application submission, depending on complete laboratory readiness and government lab test reports.
