What is the Tariff Advisory Committee (TAC)?

TAC was the statutory body that set fire insurance tariffs in India and, with them, the fire protection rules a facility had to meet to qualify for cover and discounts. Although insurance pricing was de-tariffed in 2007, TAC's fire protection rules remain the reference many Indian insurers and risk engineers still inspect against, which is why 'TAC compliance' language survives in tenders to this day.

The Centre for Fire, Explosive and Environment Safety is a DRDO laboratory in Delhi working on fire, explosive and environmental safety technologies. In the fire protection market it matters as an Indian government evaluation and advisory body: its assessments and test reports are one of the recognised routes for establishing a fire suppression technology's credentials for Indian projects, particularly government and defence-linked ones.

Is there a single mandatory 'approval' for water mist systems in India?

No. India has no single dedicated water mist product certification today. Acceptance is assembled project-by-project from the NBC-derived requirements of the state, the fire consultant's design review, the insurer's risk engineering expectations shaped by the TAC lineage, and — where the client requires it — evaluation by bodies such as DRDO-CFEES, supported by international evidence like NFPA 750-based design and EN 14972 fire testing.

What should a buyer ask a supplier about Indian approvals?

Ask for the supplier's status per standard and body, stated in writing with distinct terms — designed-to, tested, certified, or in progress — rather than an undifferentiated 'TAC/CFEES approved' claim. A certificate has a number, an issuer and a scope; status language that names all three is checkable, and status language that avoids them is a warning sign.

TAC and DRDO-CFEES: Fire Approval in India

Indian fire protection tenders regularly ask for two things international suppliers have never heard of: "TAC compliance" and "CFEES evaluation". Both names carry real weight in how Indian projects accept fire suppression systems — and both are widely misunderstood, including by suppliers who claim them loosely. This article explains what each body actually is, what role it plays today, and how a water mist system realistically moves through the Indian acceptance landscape.

TAC: the tariff body whose rules outlived it

The Tariff Advisory Committee was the statutory body that governed fire insurance tariffs in India. Its leverage was financial: a facility that met TAC's fire protection rules — hydrant coverage, pump capacities, water storage, sprinkler provision by risk class — qualified for insurance cover on better terms. Those rules, embodied in TAC's fire protection documentation, became the de facto national fire engineering reference for industrial India.

Insurance pricing was de-tariffed in 2007, ending TAC's rate-setting role. The rules, however, outlived the tariff: Indian insurers' risk engineers still inspect against the TAC lineage of fire protection requirements, and tender documents still say "as per TAC" as shorthand for that body of rules. For a water mist project this matters at the insurance review: the insurer's engineer will map the proposed system against expectations that were written around hydrants and sprinklers, so the supplier must be able to show — with engineering, not assertion — how the mist system delivers the protection intent those rules encode.

DRDO-CFEES: the government evaluation laboratory

The Centre for Fire, Explosive and Environment Safety (CFEES) is a Delhi-based laboratory of the Defence Research and Development Organisation working across fire, explosive and environmental safety — technology development, evaluation and an advisory role for government establishments. In the fire suppression market, CFEES functions as one of India's recognised technical evaluation routes: its assessments and reports carry particular weight in government, defence-linked and public-infrastructure projects, where a purely foreign certificate may not be sufficient on its own.

There is an honest nuance here that suppliers often blur: CFEES evaluation is not a blanket product certification like an FM Approval or a VdS certificate. It is an evaluation route whose scope is defined case by case. A supplier claiming "CFEES approved" should be able to show the document, its date and its scope — the same discipline that applies to any certification claim.

How acceptance actually gets assembled

Because India has no single dedicated water mist certification today, acceptance for a real project is assembled from layers, and it helps to name them in the order they usually bite:

State bye-laws and the fire NOC — the NBC-derived requirements that decide whether the building needs fixed suppression at all, covered in our article on NBC 2016 Part 4.
The fire consultant's design review — where the water mist system's engineering basis (NFPA 750 design, EN 14972 test framework, the manufacturer's fire-test-backed design manual) is examined.
The insurer's risk engineering — the TAC-lineage review described above.
Client-specific evaluation — where a government or infrastructure client requires an Indian institutional assessment, the DRDO-CFEES route.

A supplier that can answer all four layers with documents — not adjectives — is a supplier whose system will survive tender scrutiny.

Where Mistelix stands

We hold ourselves to the same standard this article recommends. Mistelix's application through the DRDO-CFEES / TAC route is in progress — that is the exact status published in our approvals ledger, using the four-term discipline (designed-to / tested / certified / planned) we never blur. Our systems are engineered with reference to NFPA 750, and everything not yet tested or certified is stated as such, openly. For the full evaluation framework a buyer should apply to any supplier, ours included, see the India buyer's guide.
