GST Compliance for Water Suppliers

GST treatment for water depends on two things: what kind of water you're supplying, and whether it's sold in a sealed container. Per CBIC's official clarification, drinking water is generally GST-exempt — but that exemption has specific conditions and exclusions that are easy to get wrong. This guide breaks down exactly what applies, based on the official government circular, not general assumptions.

GST Rates by Water Type

Under CBIC Circular No. 52/26/2018-GST, water falling under HS code 2201 is exempt from GST — except when it's aerated, mineral, purified, distilled, medicinal, ionic, battery, or demineralized water, or when it's sold in a sealed container. That last condition matters as much as the water type itself: even ordinary drinking water becomes taxable once it's sold in a sealed container, regardless of branding.

Water Type	GST Treatment
Drinking water, not in a sealed container	NIL (exempt)
Water sold in a sealed container	Taxable
Aerated water	Taxable
Mineral water	Taxable
Purified, distilled, or demineralized water	Taxable
Medicinal, ionic, or battery water	Taxable
Water tanker supply, delivered loose (not sealed containers)	Generally exempt

Do You Need GST Registration?

If you supply only exempt water (loose drinking water, not in a sealed container, and not in an excluded category), GST registration generally isn't required — unless your business also includes taxable supplies, or your turnover crosses the registration threshold on those taxable supplies. If any part of your business involves sealed-container water, mineral water, or purified/distilled water, registration is typically required for that portion of your business.

Common Mistakes

Assuming all drinking water is automatically exempt

The exemption depends on container type and water category, not just whether the water is "plain drinking water".

Missing that sealed-container sales are taxable

This applies even to ordinary drinking water once it's bottled or sealed, not just to branded or mineral water.

Overlooking the specific exclusion list

Purified, distilled, and demineralized water are explicitly excluded from the exemption, which surprises many RO-based suppliers whose output technically falls into these categories.

Not maintaining documentation

If audited, you need to show why a specific supply was classified as exempt, referencing the actual water type and container status.

Per CBIC Circular No. 52/26/2018-GST, drinking water is GST-exempt when it's not sold in a sealed container and doesn't fall into an excluded category — aerated, mineral, purified, distilled, medicinal, ionic, battery, or demineralized water. Sealed-container sales and these excluded water types are taxable regardless of branding.

Purified water is explicitly excluded from the NIL rate under the circular, so RO-purified water supplied by a business is generally taxable, even when delivered loose rather than in sealed containers. Confirm your specific classification with a tax professional, as your exact process and packaging affect this.

If you supply only exempt water and stay under the registration threshold, you may not need registration. If any part of your supply is taxable — sealed containers, purified water, or other excluded categories — registration is typically required for that portion.

This circular was issued in 2018 and remains the primary CBIC clarification on drinking water GST classification, based on available official sources. Given that GST rules are periodically amended, confirm current applicability with a tax professional or the official GST portal before filing.

GST is a tax classification issue; FSSAI/BIS licensing is a food-safety and quality requirement — you need to comply with both independently.
