BIS Parallel Testing is a voluntary, expedited compliance pathway under the Bureau of Indian Standards' Compulsory Registration Scheme (CRS) for electronics and IT goods in India. Rather than testing product components sequentially, parallel testing allows all components to be tested simultaneously at a BIS-approved laboratory, with each successive test report cross-referencing the previous one. BIS made the scheme permanent on 9 January 2024 after a pilot for mobile phones launched in December 2022. It is now open to all CRS-notified product categories and can reduce registration timelines by 4 to 13 weeks. Participation remains entirely optional — manufacturers may continue to use the standard sequential application process if preferred.
Speed to market matters enormously in the electronics and IT goods sector. Product cycles are short, launch windows are narrow, and the cost of a delayed BIS registration — in lost sales, held inventory, or missed market entry — can dwarf the cost of compliance itself. For years, manufacturers and importers entering India's market through the BIS Compulsory Registration Scheme had no choice but to accept the timeline imposed by sequential laboratory testing: component tested, report issued, next component tested, and so on, until the complete test evidence set was ready.
BIS Parallel Testing changes that equation. By allowing all components to be tested simultaneously — with test reports cross-referencing each other in a traceable chain — the scheme eliminates the waiting time between component tests and compresses the registration timeline substantially. This guide explains exactly how it works, why it matters, which products can use it, and how Rego Services helps manufacturers and importers implement it correctly.

Background: From Pilot to Permanent Scheme
BIS Parallel Testing did not emerge as a fully-formed permanent scheme. Its path from concept to institution followed a deliberate trajectory that reflects both BIS's responsiveness to industry feedback and the practical constraints of piloting a fundamentally different testing model within the existing CRS framework.
What Is BIS Parallel Testing?
Under the standard BIS CRS process, a product with multiple components requiring individual testing moves through those tests one at a time — each test begins after the previous report is issued, creating a sequential chain of waiting periods that compounds into significant total delay before an application can be filed.
BIS Parallel Testing eliminates that sequencing constraint. It allows a manufacturer to submit all components to a BIS-approved laboratory simultaneously and initiate testing across all of them at the same time. The mechanism for maintaining traceability across these simultaneous tests is the cross-referencing of test reports: the laboratory issues a test report for the first component, and when testing the next component, that first report's number and the laboratory's name are incorporated directly into the second report. This process continues for each subsequent component, creating a progressive, traceable chain of test evidence that demonstrates the simultaneous and coordinated nature of the testing.
The scheme operates within the framework of Conformity Assessment Scheme II of Schedule II of the BIS (Conformity Assessment) Regulations, 2018, which governs CRS registration for electronics and IT goods. Parallel testing does not change the underlying standards to which products must conform, nor does it alter the document requirements for the final BIS registration application — it changes only the timing and sequencing of the testing phase.
Products Eligible for BIS Parallel Testing
Since the scheme was made permanent in January 2024, all product categories notified under the BIS Compulsory Registration Scheme are eligible for the parallel testing pathway. In practical terms, however, the scheme has the greatest impact for electronics and IT goods with multiple testable components and relatively tight product launch timelines.
The original December 2022 pilot was launched for mobile phones — the single highest-volume CRS category — where the sequential testing backlog was most pronounced and the time-saving benefit most immediately demonstrable.
Wireless earphones, headphones, laptops, notebooks, and tablets were added during the pilot extension in mid-2023, broadening both the scope of the scheme and the evidence base for its effectiveness before the January 2024 expansion.
As of January 2024, any product whose registration falls under Conformity Assessment Scheme II — encompassing the full range of CRS-notified electronics, IT goods, and other regulated categories — may use the parallel testing pathway.
The parallel testing pathway is entirely optional. Manufacturers and importers who prefer the standard sequential application process retain that option without any disadvantage — parallel testing is an additional pathway, not a replacement for the existing procedure.
Benefits of BIS Parallel Testing
The case for parallel testing rests on three distinct but related advantages — time, compliance agility, and resource efficiency — each of which has meaningful implications for a manufacturer's route to market in India.
By compressing the testing phase from sequential to simultaneous, parallel testing can save 4 to 13 weeks off the overall BIS CRS registration timeline — a window that matters greatly for product launches with fixed market entry dates or time-sensitive commercial agreements.
Parallel testing enables companies to meet stringent BIS deadlines more reliably, particularly for product categories experiencing high registration demand. Earlier compliance also means earlier market access and faster recovery of the commercial investment in regulatory preparation.
Running multiple component tests concurrently maximises the throughput of available laboratory and internal QA resources. Rather than being occupied sequentially by a single product's components over an extended period, the same resources complete the full test set in a compressed window — improving both productivity and cost-efficiency.
For manufacturers in competitive electronics categories where speed to market translates directly into revenue and market share, BIS Parallel Testing provides a structural advantage over competitors still navigating the slower sequential pathway — particularly during high-demand launch periods.
The 6-Step BIS Parallel Testing Process
The parallel testing process follows a defined sequence that preserves the regulatory integrity of the CRS testing framework while eliminating the waiting periods between individual component tests.
Verify that your product falls within a CRS-notified category and confirm the decision to use the parallel testing pathway rather than the standard sequential submission. This decision should be made before laboratory arrangements are finalised.
Map all sub-components and product elements that individually require testing under the applicable Indian Standard. Accurate upfront mapping ensures that no testable component is missed — a gap at this stage would require a return to sequential testing for the omitted component.
Submit samples of all components to a BIS-recognised laboratory at the same time, initiating the parallel testing programme. The laboratory begins testing the first component and issues a test report containing its report number and the laboratory's name.
For each subsequent component tested, the report number and laboratory name from the preceding component's test report are incorporated into the current report. This progressive cross-referencing continues for all components, creating a traceable chain of simultaneous test evidence that BIS can audit.
Once all components have been tested and their cross-referenced reports issued, compile the complete parallel test report set. This set, together with all other required registration documents, forms the basis for the BIS CRS application.
File the complete BIS CRS registration application with the full parallel test report set, all required supporting documents — entity identity, facility, brand ownership — and the applicable registration fee. The application then proceeds through the standard BIS review and approval process.
Governing Guidelines for BIS Parallel Testing
BIS Parallel Testing for CRS registration is governed by two sets of registration guidelines issued in December 2022, which were subsequently made permanent in January 2024:
The scheme is governed by Registration Guidelines RG: 01, dated December 15, 2022, concerning "Guidelines for Grant of License (GoL) under Conformity Assessment Scheme II of Schedule II of the BIS (Conformity Assessment) Regulations, 2018," along with Registration Guidelines RG: 01, dated December 16, 2022. These guidelines establish the mechanism for cross-referencing test reports, the laboratory requirements, and the scope of the parallel testing programme across CRS product categories.
The guidelines make clear that parallel testing operates within the existing CRS framework — the same Indian Standards, the same laboratory recognition requirements, and the same documentation obligations apply. What changes is exclusively the timing of the testing phase: from sequential to simultaneous, with cross-referenced reports providing the traceability chain that the sequential process would otherwise have established through the natural order of submission.

Limitations of BIS Parallel Testing
BIS Parallel Testing offers genuine time savings, but it is not without constraints. Understanding these limitations upfront allows manufacturers and importers to plan their testing programme correctly and avoid the situations where the parallel pathway either adds cost or cannot be meaningfully applied.
Conducting all component tests simultaneously requires a full complement of physical devices, adapters, and testing equipment for each component at the same time. For products with many components, the upfront cost of assembling this full test set — rather than cycling the same equipment through sequential tests — can be substantial.
Some test cases have inherent sequential dependencies — where the outcome of one test determines the conditions for the next. Where these dependencies exist within a product's required test suite, those specific tests cannot be run in parallel. Identifying these constraints in advance is essential to avoid test validity issues.
Managing multiple simultaneous tests — across components, laboratory slots, and report cross-referencing requirements — demands more intensive coordination than sequential testing. Without experienced project management of the parallel testing programme, the coordination overhead can partially erode the time savings the scheme is designed to deliver.
Establishing the parallel testing environment — planning the test scope, configuring laboratory arrangements, and ensuring all components and equipment are ready for simultaneous submission — requires careful upfront preparation. Inadequate planning at this stage can delay the start of testing and reduce the net time saving.
Parallel Testing vs. Sequential Testing: Key Differences
Understanding the practical differences between the two pathways is essential for deciding whether parallel testing is the right choice for a specific product registration project.
| Dimension | Sequential Testing (Standard) | Parallel Testing (Expedited) |
|---|---|---|
| Testing order | One component at a time; each test begins after the previous report is issued | All components tested simultaneously; test reports cross-reference each other |
| Registration timeline | Full sequential testing period — waiting time compounds across components | 4–13 weeks faster; no waiting time between component tests |
| Participation | Standard default pathway for all CRS applicants | Voluntary — applicant must opt in explicitly |
| Equipment requirement | Lower — same equipment can be used across sequential tests | Higher — full device/equipment set needed simultaneously for all components |
| Coordination demand | Lower — one test at a time, straightforward tracking | Higher — multiple simultaneous tests require active coordination |
| Best suited for | Products with fewer components, lower launch urgency, or limited test equipment | Products with multiple testable components and time-sensitive market entry targets |
| Applicable to | All CRS-notified product categories | All CRS-notified product categories (since January 2024) |

Frequently Asked Questions
Can manufacturers outside India use BIS Parallel Testing for CRS registration?
Yes. Foreign manufacturers seeking BIS CRS registration for electronics or IT goods in India — through an Authorised Indian Representative (AIR) — can use the parallel testing pathway in the same way as domestic manufacturers. The key practical consideration is that the physical samples of all components must be submitted simultaneously to a BIS-approved laboratory in India, which requires advance planning of sample logistics, particularly for manufacturers shipping from outside the country.
Does choosing parallel testing affect the standards my product must comply with?
No. Parallel testing changes only the sequencing and timing of the testing phase — the applicable Indian Standard, the specific tests required, and the compliance thresholds remain identical to those applicable under the sequential pathway. BIS Parallel Testing is a procedural mechanism, not a different set of technical requirements.
What happens if one component fails testing in a parallel testing programme?
If a component fails testing during the parallel programme, the test report for that component will reflect non-compliance. The manufacturer would need to address the non-compliance — typically through design or specification correction and retesting — before the full parallel test evidence set can be used to support a successful BIS registration application. The implications of a test failure are the same as under sequential testing; the difference is that other components' tests are already complete, so retesting the failed component does not require restarting the full process.
Is BIS Parallel Testing available for products under FMCS (Foreign Manufacturers' Certification Scheme) as well as CRS?
The parallel testing guidelines published by BIS are specific to the Compulsory Registration Scheme (CRS) under Conformity Assessment Scheme II. For products under the Foreign Manufacturers' Certification Scheme (FMCS) or other BIS certification schemes, manufacturers should confirm the applicable testing procedures with their BIS consultant, as the parallel testing mechanism described in this guide pertains specifically to CRS-notified products.
