Key takeaways

BIS certification is issued by the Bureau of Indian Standards under the BIS Act, 2016 and the BIS (Conformity Assessment) Regulations, 2018.
There are three main schemes: the ISI mark scheme, the Compulsory Registration Scheme (CRS) for electronics, and the Foreign Manufacturers Certification Scheme (FMCS) for overseas makers.
For many products it is mandatory under a Quality Control Order (QCO) before you can manufacture, import or sell in India.
Applications are filed online through the BIS Manak Online portal, with product testing at a BIS-recognised laboratory.
A Delhi-based consultant shortens the journey by handling the application, factory documentation, sample testing and follow-up with the BIS regional office.
ISI licences are typically granted for 1 to 2 years and renewed thereafter; CRS registrations run for 2 years.

Overview

What is BIS certification?

BIS certification is the formal assurance from the Bureau of Indian Standards that a product conforms to the relevant Indian Standard (IS) for safety, quality and performance. The Bureau is India’s national standards body, operating under the BIS Act, 2016, and its certification marks tell consumers, retailers and regulators that a product has been independently tested and verified.

For a growing list of products notified under Quality Control Orders by the respective Ministries, certification is not optional. You cannot legally manufacture, store, sell or import these goods in India without the appropriate BIS licence or registration. Securing it correctly the first time avoids seizures, penalties and lost market access.

Schemes

Types of BIS certification

The scheme you need depends on your product category and whether you manufacture in India or abroad. These are the routes we handle most often for Delhi and NCR clients.

Scheme	Who it is for
ISI Mark (Scheme I)	Indian manufacturers of products notified under a Quality Control Order, such as cement, steel, electrical appliances and packaged water.
Compulsory Registration Scheme (CRS)	Makers and importers of notified electronics and IT goods, who self-declare conformity after testing.
Foreign Manufacturers Certification Scheme (FMCS)	Overseas manufacturers who wish to use the ISI mark on goods exported to India.

Other approvals	Purpose
Hallmarking	Mandatory certification of gold and silver jewellery purity.
Eco Mark	Recognition for environment-friendly products.
Management System Certification	System-level certification against standards such as quality and food safety.

Applicability

Who needs BIS certification

If your product appears in a Quality Control Order, BIS certification is a legal precondition to doing business in India. Even where it is voluntary, the mark is a powerful trust signal across retail, e-commerce and government procurement. The following businesses typically require it.

Manufacturers of cement, steel, pipes and construction materials
Producers of electrical appliances, switches, cables and wiring
Makers and importers of mobile phones, power banks, LED lighting and IT equipment (CRS)
Packaged drinking water and food-grade product manufacturers
Toy manufacturers and importers covered by the Toys QCO
Foreign manufacturers exporting notified goods into India (FMCS)

Compliance

Why certification is mandatory

For products under a Quality Control Order, the BIS Act, 2016 makes the use of the Standard Mark compulsory. Manufacturing, importing, storing or selling a notified product without a valid licence is an offence, and the Bureau is empowered to act against violators directly.

What non-compliance can cost you

Fines and imprisonment under the penalty provisions of the BIS Act, 2016.
Seizure of stock and sealing of manufacturing premises.
Removal from e-commerce and rejection at import customs clearance.
Loss of tenders, as government procurement increasingly requires BIS-certified goods.

How it works

The certification process, step by step

Filing is fully online through the BIS Manak Online portal. The path differs for the ISI mark scheme and the Compulsory Registration Scheme.

ISI mark (Scheme I)

Identify the standard
Confirm the applicable Indian Standard and gather product, factory and machinery details.
Apply on Manak Online
Submit the application with factory documents, test equipment list and process flow.
Factory inspection
A BIS officer audits the premises, in-house testing capacity and quality controls.
Sample testing
Samples are drawn and tested at a BIS-recognised laboratory against the standard.
Grant of licence
On satisfactory results, the licence to use the ISI mark is issued.

CRS registration

Test the product
Get the product tested at a BIS-recognised lab against the relevant IS standard.
Compile the dossier
Prepare the test report, factory details and, for importers, authorisation documents.
Apply for registration
File the application on Manak Online with the laboratory test report attached.
Review by BIS
BIS examines the application and test data, raising queries if needed.
Registration granted
The registration number is issued, allowing use of the standard mark with R-number.

Paperwork

Documents required

Business registration or incorporation documents
Factory registration and trade licence
Identity and address proof of the authorised signatory
Manufacturing process flow chart and product details

Lifecycle

Validity & renewal

An ISI mark licence is typically granted for 1 to 2 years and renewed before expiry.
A CRS registration is valid for 2 years and must be renewed to stay active.
BIS conducts periodic surveillance and may draw market samples for testing.
A licence can be suspended or cancelled for non-conformity or marking misuse.

Budgeting

Fees, timeline & cost factors

Total cost varies with the scheme, the number of products and standards involved, and laboratory testing charges. The typical components are set out below.

Cost factor	Details
Application and licence fee	Statutory fees payable to BIS per the conformity assessment regulations.
Laboratory testing	Charged by the BIS-recognised lab, depending on the product and number of tests.
Factory inspection (ISI)	Inspection and travel charges where on-site audit is required.
Consultancy and documentation	Preparation, filing and follow-up handled by Diligence Certifications.
Renewal fee	Payable on renewal at the end of the licence or registration term.

Indicative timelines run from a few weeks for CRS to around two to four months for ISI, driven mainly by testing turnaround and inspection scheduling.

FAQ

Frequently asked questions

What is BIS certification?

BIS certification is the approval issued by the Bureau of Indian Standards confirming that a product conforms to the relevant Indian Standard for safety and quality. It is granted under the BIS Act, 2016, and is mandatory for products notified under Quality Control Orders.

Who issues BIS certification in India?

The Bureau of Indian Standards, the national standards body, issues all BIS licences and registrations. Applications are filed online through the BIS Manak Online portal and routed through its regional and branch offices.

What is the difference between the ISI mark and CRS registration?

The ISI mark scheme covers products such as cement, steel and electrical appliances, and requires factory inspection plus sample testing. CRS is a self-registration scheme for notified electronics and IT goods, granted on the basis of a laboratory test report without routine factory audit.

How long does BIS certification take in Delhi?

CRS registration usually takes a few weeks once testing is complete, while an ISI licence commonly takes around two to four months. The main variables are laboratory testing turnaround and the scheduling of the factory inspection.

Can a foreign manufacturer obtain BIS certification?

Yes. Overseas manufacturers apply under the Foreign Manufacturers Certification Scheme (FMCS), which allows them to use the ISI mark on notified goods exported to India, subject to inspection, testing and appointment of an authorised Indian representative.

How long is a BIS licence valid?

An ISI mark licence is generally granted for one to two years and renewed before expiry, while a CRS registration is valid for two years. BIS also carries out periodic surveillance and market sampling to ensure continued conformity.
