Your R-no. Stays the Same

Manufacturers migrating from IS 13252 (Part 1):2010 or IS 616:2017 do not need to worry about losing their existing Licence Number. BIS has confirmed the R-no. remains unchanged after successful migration to IS/IEC 62368-1:2023.

Separate Licences Migrate Separately

Where a manufacturer holds separate licences for different product categories — for example, power adaptors for IT equipment versus power adaptors for audio/video equipment — each licence continues independently, and migration must be carried out separately for each licence, in accordance with the implementation guidelines. This means a manufacturer with multiple product lines cannot migrate all licences under a single combined application; each R-no. follows its own migration path and timeline.

Marking Format Under Regulation 6

Products certified under IS/IEC 62368-1:2023 must carry the BIS Standard Mark as per Regulation 6 (Labelling and Marking Requirements) and Annexures I, II, and III of Scheme II, Schedule II of the BIS Conformity Assessment Regulations, 2018. The mark itself displays the standard reference “IS/IEC 62368-1” with the R-number printed beneath it. Manufacturers updating product labelling as part of migration should confirm their artwork reflects this exact format before finalising packaging and product markings, since a mismatched or outdated mark format can itself become a point of objection during BIS review.

Verify Lab Recognition on LIMS

BIS-recognised laboratories for testing under IS/IEC 62368-1:2023 can be located via the BIS Laboratory Information Management System (LIMS) portal at lims.bis.gov.in, simply by searching the applicable Indian Standard number. Manufacturers should confirm a lab's recognition specifically against IS/IEC 62368-1:2023 (rather than assuming recognition under the older standards automatically carries over), since testing scope on LIMS is standard-specific.

Renewal Under Old Standards Permitted Till 2028

Licences due for renewal during the transition can still be renewed under the old standards (IS 13252 Part 1:2010 / IS 616:2017) up to 01 November 2028 — the last date of concurrent running notified by MeitY. This gives manufacturers a clear runway: renewal doesn't force immediate migration, but the window is finite, and licensees should plan their migration testing well ahead of the deadline rather than treating 2028 as a last-minute cut-off.

Either Standard Accepted Until the Cut-Off

Until 01 November 2028, applications may be filed under either the old standards or IS/IEC 62368-1:2023, provided applicants filing under the old standard submit a declaration committing to implement IS/IEC 62368-1:2023 by the last date of concurrent running. BIS has explicitly stated that applicants are encouraged, though not yet mandated, to file new applications directly under IS/IEC 62368-1:2023.

New Models Can Join Under Clause 4(C)

New models tested under IS/IEC 62368-1:2023 can be added to an existing licence originally issued under the old standards, subject to Clause 4(C) of the Migration Implementation Guidelines dated 09 March 2026. As with full migration, failure to complete migration by the concurrent-running deadline can still trigger cancellation or deletion of models, even where individual new models were added mid-transition.

All Lead Models Require Complete Test Reports

A common misconception is that one representative sample per licence is sufficient for migration testing. BIS has clarified this is not the case. Existing licensees must submit complete test reports, issued by a BIS-recognised laboratory, for all lead models in their licence scope — identified in line with the revised Series Guidelines — that were previously tested under IS 13252 (Part 1):2010 or IS 616:2017. In practice, this means licensees should first map their full licence scope against the current Series Guidelines to correctly identify every lead model requiring fresh testing, rather than assuming a single flagship model covers the entire portfolio.

EOL Models Can Be Substituted

If a lead model designated for migration testing has reached end-of-life, it may be withdrawn from the licence by the licensee. The next appropriate lead model within the same series — identified per the MeitY Series Guidelines — then takes its place as the reference model for demonstrating compliance. This avoids forcing manufacturers to test a discontinued product purely to satisfy migration formalities.

Separate Reports Per Site

Separate test reports are required for products manufactured at different manufacturing locations, since separate licences are granted per location under the Compulsory Registration Scheme (CRS). Manufacturers operating multi-site production should factor this into their migration timeline and lab-scheduling plans, as it effectively multiplies the testing workload across sites.

Refer to Clauses 4.A.(6) and 4.A.(7)

Where migration to IS/IEC 62368-1:2023 has knock-on effects for compliance with other applicable standards or Essential Requirements, applicants should refer specifically to Clauses 4.A.(6) and 4.A.(7) of the Migration Implementation Guidelines dated 09 March 2026 for the applicable provisions.

Components and End Products Can Be Tested Together

Components and end products notified under the Compulsory Registration Order (CRO) may be tested in parallel, in accordance with BIS's Guidelines on Parallel Testing. This allows manufacturers to progress component-level and finished-product testing simultaneously rather than sequentially, which can meaningfully shorten overall migration timelines.

No Fee for Already-Registered Models

No fee is applicable for migrating already-registered models within the existing scope of licence, provided the migration is applied for through the Standard Revision provision available to existing licensees. This removes cost as a barrier to timely migration for manufacturers already holding valid licences.

Old-Standard Components Must Be Reassessed

Critical components complying only with IS 13252 (Part 1):2010 or IS 616:2017 cannot be accepted in the CCL after migration. Clause 4.1.2 of IS/IEC 62368-1:2023 requires that where a component (or a characteristic of it) functions as a safeguard, it must comply either with IS/IEC 62368-1:2023 itself, or, where specified in a requirements clause, with the safety aspects of the relevant IEC component standards.

This is a meaningful compliance obligation: manufacturers cannot simply carry forward previously-approved critical components without reassessing them against the new standard. However, BIS does permit applicants to register critical components and end products in parallel, per the Parallel Testing Guidelines, easing the practical burden of this requirement.

Declaration Required for Registered Models

Models already registered and bearing the BIS Standard Mark may still be submitted to a BIS-recognised laboratory for testing under IS/IEC 62368-1:2023. The applicant must declare at the time of submission that the model is already registered, and the laboratory is required to record this declaration in the test report.

Testing Can Begin Before the Application Is Filed

Manufacturers are not required to wait until formally submitting a migration application before beginning testing. Testing under IS/IEC 62368-1:2023 may proceed in accordance with the implementation guidelines and applicable Series Guidelines at any point — allowing manufacturers to get ahead of the process operationally while formal paperwork is finalised.

File via Standard Revision/Amendment in Your BIS CRS Login

Existing licensees apply for migration through the Standard Revision / Amendment / Essential Requirement provision available within their BIS CRS login. The application must include complete test reports for all applicable lead models — identified per the revised Series Guidelines — and must be submitted in accordance with the Guidelines for Implementation of Migration to IS/IEC 62368-1:2023 dated 09 March 2026.
