Key takeaways

BIS certification is issued by the Bureau of Indian Standards, India’s national standards body under the BIS Act, 2016.
It runs through several schemes - the ISI mark (Scheme I), CRS registration (Scheme II / Compulsory Registration Scheme), FMCS for foreign manufacturers, and Hallmarking for gold and silver.
For products under a mandatory QCO (Quality Control Order), certification is compulsory before you can manufacture, import or sell in India.
Every scheme requires product testing in a BIS-recognised lab against the relevant Indian Standard (IS).
Diligence Certifications manages the entire journey - scheme selection, application, testing, factory audit and licence grant.

What is BIS Certification?

BIS certification is a conformity mark that confirms a product meets the applicable Indian Standard (IS) for safety, quality and performance. Administered by the Bureau of Indian Standards, it is the single most recognised quality assurance in the Indian market. Depending on the product, certification is either mandatory (covered by a Quality Control Order) or voluntary (taken for market credibility).

Because “BIS certification” is an umbrella term, the first step is always identifying the correct scheme and Indian Standard for your product. Choosing the wrong route is the most common reason applications stall.

The BIS certification schemes

ISI Mark (Scheme I, Schedule II): the classic ISI mark for domestic and foreign manufacturers of products such as cement, electrical appliances, pipes, food and packaged water. ISI mark certification →
CRS - Compulsory Registration Scheme (Scheme II): self-declaration based registration for electronics and IT products notified by MeitY (mobiles, laptops, LED lighting, power adaptors and more). BIS CRS certification →
FMCS - Foreign Manufacturers Certification Scheme: the route for manufacturers located outside India to obtain a BIS licence to use the ISI mark.
Hallmarking: mandatory BIS hallmarking for gold and silver jewellery, with a HUID for traceability. Hallmarking registration →
Scheme X: the newer machinery and electrical equipment route under the 2021 conformity assessment regulations.

Who needs BIS certification?

Indian manufacturers of any product covered by a mandatory Indian Standard or QCO.
Importers and foreign manufacturers shipping notified products to India (via FMCS or CRS).
Electronics and IT brands whose products fall under the MeitY CRS list.
Jewellers selling gold or silver, who must sell only hallmarked pieces.
Sellers and e-commerce brands who need certified products to list and supply legally.

The BIS certification process

1. Scheme & standard identification - confirm whether your product is mandatory, and the exact IS number and scheme.
2. Application - file on the BIS portal (Manak Online) with technical documentation and product details.
3. Product testing - samples are tested in a BIS-recognised laboratory against the IS.
4. Factory audit - for ISI/FMCS, a BIS officer inspects the manufacturing premises and quality controls (CRS is largely document + test based).
5. Grant of licence / registration - on a satisfactory test report and audit, BIS grants the licence and you may apply the mark.
6. Surveillance & renewal - periodic market and factory surveillance, with renewal before expiry.

Documents typically required

Manufacturer and factory details (registration, address proof, layout)
Product specifications, list of models/variants and test plan
Details and calibration records of in-house testing machinery
For FMCS - authorised Indian representative (AIR) details
For CRS - MeitY product mapping and a registered Indian address
Trademark / brand documentation, where applicable

Validity & timeline

An ISI licence is generally granted for an initial period and renewed thereafter; CRS registration is typically valid for two years and renewable. The end-to-end timeline depends almost entirely on testing turnaround and (for ISI/FMCS) audit scheduling - a clean application with samples ready is far faster than one that needs re-testing. We give you a realistic, product-specific timeline upfront rather than a generic promise.

Frequently asked questions

Is BIS certification mandatory for my product?

It is mandatory if your product is covered by a Quality Control Order (QCO) or notified under the CRS list. Many other products can be certified voluntarily for market credibility. The first step is confirming which category your product falls in.

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

The ISI mark (Scheme I) applies to a broad range of products and involves factory audit plus testing. CRS (Scheme II) is a registration route for notified electronics and IT products, based mainly on testing and self-declaration without a routine factory audit.

Can a foreign manufacturer get BIS certification?

Yes. Foreign manufacturers apply through the Foreign Manufacturers Certification Scheme (FMCS) for the ISI mark, or through CRS for notified electronics, and must appoint an Authorised Indian Representative.

Is product testing always required?

Yes. Every BIS scheme requires the product to be tested against the relevant Indian Standard in a BIS-recognised laboratory before a licence or registration is granted.

How long is a BIS licence valid?

It varies by scheme - ISI licences are renewed periodically and CRS registration is typically valid for two years, both renewable. We track renewals so your certification never lapses.

Which BIS scheme applies to my product?

That depends on the product category and the governing notification. Share your product details with our team and we will identify the exact Indian Standard and scheme, and map out the certification route for you.
