BIS certification for electrical products: scope, routes and marking

What BIS certification is

The Bureau of Indian Standards is the national standards body, and it operates the conformity assessment schemes that sit behind the ISI mark. A product that is covered by a quality control order or by a notified scheme cannot legally be sold in India without the right licence or registration. The requirement attaches to the product and the standard, not to the supplier's reputation.

That last point is where buyers lose time. A supplier may hold a licence for one product family and assume it covers a new part. It does not. The scope of a licence lists the product and the standard, and a different rating, construction or material can fall outside it. Ask for the licence and read the scope before you plan a launch.

The two routes a buyer will meet

Most electrical and electronic products enter India through one of two routes. The first is the ISI mark licence, used where the product is under compulsory certification. The second is registration under the compulsory registration scheme, used mainly for electronics and information technology goods. They are not interchangeable, and a product may need one, the other, or both across its accessory range.

Licence versus registration

The practical difference is the factory. A licence route includes an assessment of the manufacturing site, so the applicant must show that the plant can make the product consistently, not only that one sample passed a test. The registration route relies on a test report from a laboratory recognised by BIS, and the surveillance is focused on the product in the market.

For a buyer, the licence route gives more evidence about the plant. The registration route is usually faster and lighter, but it says less about the production line. If the product is safety critical or the supplier is new to you, the lighter route is not a reason to skip the audit. It is a reason to do your own.

How to check whether a product is covered

Start with the Indian standard for the product family. Then check whether a quality control order or a notified scheme makes that standard mandatory. The BIS website publishes the list of products under compulsory certification and the list under registration, and both lists change. A product that was outside scope last year may be inside it now.

Do not rely on a supplier's statement that certification is not needed, and do not rely on a certificate for a similar product. Ask for the standard number, the licence or registration number, the model or rating covered and the validity date. If the answer is a photograph of a mark without a number, the answer is incomplete.

Surveillance is the other part of the scheme. A licence or registration can be reviewed after approval, and a sample may be drawn from the market or the factory. The product sold in month twelve must still match the tested configuration. Ask the supplier how the version, the components and the marking are controlled after approval.

Testing and the factory assessment

Testing is carried out at a laboratory recognised by BIS for the relevant standard. The sample must be representative of production, and the test report has a shelf life and a scope. A report for a prototype built with a different component set may not support a registration for the production version.

Where a factory assessment applies, expect the inspector to look at the production process, the test equipment, the calibration records, the incoming material control and the marking arrangement. The assessment is not a product design review, but it does test whether the plant can repeat what the sample did. Prepare the records before the visit, because a missing calibration label can delay the whole application.

• Standard number and test report scope
• Sample identity and production configuration
• Calibration records for the test equipment
• Incoming material and component control
• Marking and traceability arrangement
• Corrective action process for failed tests

Marking, labelling and the licence number

Approval is not complete until the product carries the right mark. The ISI mark is applied with the licence number, and the registration route uses a registration number in the prescribed form. The position, size and durability of the mark are part of the requirement, so a label that rubs off in transit is a compliance problem, not a cosmetic one.

Packaging usually carries the mark as well, along with the importer details and the country of origin where required. If the product is private labelled, confirm who holds the licence and whose number appears on the goods. A buyer that puts its own brand on an uncertified product inherits the problem, even if the factory made the part.

Timelines, changes and common pitfalls

Timelines depend on the route, the laboratory queue and whether the application is complete. A registration with a valid test report can move quickly. A licence with a factory inspection and a corrective action cycle can take far longer. Plan the certification as a critical path item, not as a task that runs beside the tooling.

Changes are the other trap. A new component, a new rating, a new factory or a new brand can all affect the approval. Build a change notification clause into the supply agreement so that the supplier tells you before a substitution is made. A cheaper capacitor or a different enclosure material can turn a compliant product into a non compliant one without anyone noticing.
