ISI Mark Registration

Earn the mark that tells buyers your product is tested, safe, and standard-compliant.

The ISI mark is the certification mark issued by the Bureau of Indian Standards (BIS) confirming that a product conforms to the relevant Indian Standard (IS) for quality, performance, and safety. For product categories notified under a Quality Control Order (QCO) — from LPG cylinders and cement to electrical appliances, helmets, and packaged drinking water — carrying the ISI mark isn't optional; it's the difference between a product that can legally be manufactured, sold, and imported in India, and one that can't.

Even where it isn't mandatory, the ISI mark is one of the most recognised trust signals in the Indian market — retailers, government tenders, and consumers all read it as proof that a product has been independently tested and that the factory producing it is audited on an ongoing basis. Getting the license right the first time means fewer rounds of factory audits and sample rejections, which is exactly where a certification expert earns their keep.

Certification Schemes

Which ISI certification scheme applies to your product?

BIS certifies products across dozens of Quality Control Orders and voluntary Indian Standards. Here's the lineup of schemes and product categories we handle most often.

Mandatory ISI Certification (QCO)

For products notified under a Quality Control Order — manufacture, sale, and import are illegal without a valid BIS license and ISI mark.

Most Common

Voluntary ISI Certification

For product categories not yet notified — manufacturers opt in to build market trust and open doors to institutional buyers and retail chains.

Electrical & Electronic Appliances

Switches, MCBs, wiring accessories, LED products, and household appliances certified under their respective IS safety standards.

Cement & Construction Materials

OPC, PPC, and other cement grades, along with structural steel and construction hardware tested for strength and composition.

LPG Cylinders & Gas Appliances

Cylinders, regulators, and gas stoves certified under stringent safety-critical IS standards with frequent surveillance testing.

Helmets & Personal Protective Gear

Two-wheeler helmets and select PPE items, certified for impact resistance and wearer safety under the relevant IS code.

Packaged Drinking Water & Food Products

Bottled water, mineral water, and select packaged food items tested for purity and compositional standards.

Toys & Children's Products

Toys certified under the Toys Quality Control Order for mechanical, physical, and chemical safety before they can be sold in India.

The Process

From standard identification to licensed mark, in eight steps

Here's exactly what happens between deciding to certify a product and holding a valid BIS license with the ISI mark on your goods.

1
Planning

Product & Standard Identification

We map your product to the correct Indian Standard (IS) number and confirm whether certification is mandatory under a QCO or voluntary.

2
Planning

Factory & Documentation Readiness

We review your manufacturing setup, in-house testing equipment, and quality control manual against BIS's minimum requirements before filing.

3
Filing

Application Filing with BIS

The formal application is submitted through the BIS CARE portal along with fees, declarations, and supporting technical documents.

4
Testing

Sample Testing at a Recognised Lab

Product samples are tested at a BIS-recognised laboratory against every clause of the applicable Indian Standard.

5
Audit

Factory Audit & Assessment

A BIS officer inspects the factory, verifies in-house testing capability, and checks that quality control is genuinely built into production.

6
Review

Compliance Verification & Query Resolution

Any non-conformities from testing or audit are addressed and resubmitted until the file meets BIS's approval bar.

7
Approval

Grant of ISI License (CM/L Number)

Once satisfied, BIS grants the license with a unique CM/L number, authorising you to apply the ISI mark to the certified product.

8
Ongoing

Mark Usage & Surveillance

We help set up the marking format correctly and prepare you for the periodic surveillance audits and market sample checks that follow.

Eligibility

Who can apply for ISI mark certification?

Requirements vary slightly by product and Indian Standard, but most applications share the same baseline criteria BIS checks before granting a license.

Registered Manufacturing Unit

A functioning factory premise where the product is actually manufactured, not merely traded or assembled.

Product Covered Under an IS Standard

The product must correspond to a published Indian Standard with a defined test method and specification.

In-House Testing Facility

Basic testing equipment on-site to perform routine checks, as prescribed by the relevant Indian Standard.

Documented Quality Control System

A traceable process for raw-material checks, in-process inspection, and finished-product testing before dispatch.

No Prior License Cancellation

Applicants must not be currently blacklisted or under a cancelled BIS license for the same or a related product.

Compliance With the Governing QCO

Where a Quality Control Order applies, the applicant must meet every clause of that order, not just the general IS requirements.

Why It's Worth It

What the ISI mark actually buys you

Beyond regulatory compliance, certification changes how the market perceives your product and where it's allowed to be sold.

Regulatory Compliance

Legal clearance to manufacture and sell QCO-notified goods

Consumer Trust & Safety

Independent proof your product meets a national safety bar

Wider Market Access

Required by most retail chains, distributors, and e-commerce platforms

Government Procurement

A prerequisite for most public tenders and institutional supply

Competitive Edge

Stands out against uncertified or grey-market alternatives

Lower Liability Risk

Documented testing reduces exposure to product-safety claims

Export Readiness

An IS-certified process is a head start on foreign compliance

Brand Reputation

One of India's most recognised marks of manufacturing quality

After Certification

Staying compliant, license after license

Getting the ISI mark is the start, not the finish — here's what keeps your license in good standing afterward.

Annual Surveillance Audit

BIS re-inspects the factory and quality systems at scheduled intervals.

Market Sample Testing

Random samples picked from the market or factory are tested for continued conformity.

License Renewal

The BIS license is renewed before expiry, typically on a one or two-year cycle.

Marking Fee & Royalty

Periodic marking fees tied to production volume are paid to BIS as per scheme rules.

Factory Change Intimation

Any change in address, machinery, or ownership must be reported to BIS promptly.

Non-Conformance Corrective Action

Any failed sample or audit finding must be corrected and closed within the stipulated timeline.

FAQ

Common questions about ISI mark registration

Can't find your question here? Use the form alongside this page and we'll answer it directly.

It's the certification mark issued by the Bureau of Indian Standards, confirming a product conforms to the relevant Indian Standard for quality and safety.

Only if your product falls under a notified Quality Control Order — we check this against your product category before you apply.

ISI mark certification (Scheme-I) involves ongoing factory audits and licensing, while CRS registration is largely a self-declaration model for certain electronics.

Typically around 45 working days from application to license grant, though it varies with lab turnaround and audit scheduling.

Factory registration, GST certificate, machinery list, process flow chart, and your quality control manual are the core set — see the Documents section above.

Yes, under Scheme-I a BIS officer inspects the manufacturing unit and in-house testing facility before a license is granted.

Licenses are typically granted for one or two years and must be renewed before expiry to keep using the mark.

Yes, foreign manufacturers can obtain a BIS license for QCO-notified products through a similar testing and audit route.

BIS raises a non-conformance that must be corrected within a set timeline, and repeated failures can lead to license suspension.

Because we handle BIS filings and audits regularly, coordinate directly with recognised labs, and stay on for compliance long after the license is granted.
