What Is TEC MTCTE Certification and Who Enforces It?

The Mandatory Testing and Certification of Telecom Equipment (MTCTE) programme is administered by the Telecommunication Engineering Centre (TEC), a technical wing of India's Department of Telecommunications (DoT). MTCTE was introduced through a DoT order in 2019 and has been progressively expanded since — with the legal framework significantly strengthened by the Telecommunications Act, 2023, which replaced the Indian Telegraph Act and gave enforcement authorities sharper tools for market surveillance and penalty imposition. Under MTCTE, any telecom or networking equipment listed in TEC's mandatory product schedule must obtain a valid TEC certificate before it can be manufactured for sale, imported, sold, offered for sale, or deployed on any Indian telecom network.

The scheme operates through a network of TEC-empanelled Conformity Assessment Bodies (CABs) — independent testing and certification organisations authorised by TEC to evaluate products against the applicable Essential Requirements and interface standards. Unlike BIS CRS, where the testing lab issues a report and the manufacturer applies directly to BIS, MTCTE places the CAB at the centre of the certification process — the CAB tests the product, evaluates technical documentation, and issues the TEC certificate directly. This gives TEC greater quality control over the certification output, but it also means the CAB's availability, workload, and efficiency directly determines how fast your certificate arrives.

As of May 2025, TEC's mandatory product schedule covers 71 equipment categories across telecom terminals, network infrastructure, enterprise networking, and IoT connectivity devices. New categories are added through periodic DoT notifications — companies that assumed their product was outside the MTCTE scope based on a 2022 or 2023 check should verify against the current schedule before importing or manufacturing in 2025.

Which Telecom and Network Products Need MTCTE Certification in 2025?

TEC's mandatory product schedule is organised into phases, with earlier phases covering high-volume consumer and enterprise equipment and later phases extending to specialised telecom infrastructure and emerging technology categories. The schedule is publicly available on the TEC website (tec.gov.in), and checking it is the mandatory first step before any compliance planning for a telecom or networking product destined for the Indian market.

Telecom Terminal Equipment

  • Mobile handsets, smartphones, and feature phones — MTCTE is mandatory in parallel with BIS CRS registration and WPC ETA; all three certifications are required before a mobile phone can be legally sold in India
  • Fixed-line telephone instruments, IP phones, and VoIP terminals connecting to the public switched telephone network
  • DSL modems, VDSL2 modems, and fibre ONT (Optical Network Terminal) units used for last-mile broadband access
  • Satellite communication terminals and VSAT equipment, including emerging LEO satellite ground terminals

Enterprise Networking Equipment

  • Wi-Fi access points and enterprise WLAN controllers — including Wi-Fi 6 (802.11ax) and Wi-Fi 7 (802.11be) equipment added to the schedule in 2024
  • Ethernet switches — both unmanaged and managed variants, for enterprise LAN and data centre applications
  • Routers and network gateways used in enterprise, SMB, and telecom operator environments
  • Network-attached storage (NAS) devices with integrated switching or routing functionality
  • SD-WAN appliances and unified threat management (UTM) devices with WAN interface connectivity

Telecom Infrastructure Equipment

  • Base transceiver stations (BTS), eNodeB, and gNodeB equipment for 4G LTE and 5G NR networks
  • Optical fibre transmission equipment including OTN multiplexers, DWDM systems, and passive optical network (PON) head-end equipment
  • IP multimedia subsystem (IMS) components and VoLTE-enabling core network elements
  • Small cells and femtocell units for indoor 4G/5G coverage — added to mandatory scope from January 2025

Critical dual-compliance trap for Wi-Fi routers and enterprise access points: these products simultaneously require TEC MTCTE certification, WPC ETA approval for the wireless module, and BIS CRS registration under the IT equipment category. Many importers obtain only one or two of these certifications and face customs detention or market withdrawal notices when the missing certification is discovered during a DoT or BIS market surveillance check. Always run a full multi-certification assessment before importing any networking product.

Step-by-Step TEC MTCTE Certification Process for 2025

MTCTE certification follows a CAB-centric workflow that is distinct from BIS CRS and WPC processes. The applicant does not file directly with TEC — instead, the entire certification process runs through the empanelled CAB, which interfaces with TEC on the applicant's behalf. Selecting the right CAB, preparing documentation to their specific requirements, and managing the CAB's internal review timeline are the three biggest variables that determine how quickly you get your TEC certificate. The TEC portal (https://tarang.tec.gov.in) is used for certificate registration and public disclosure, but the actual certification work happens at the CAB level.

1
Identify Applicable Essential Requirements and Interface Standards

Every MTCTE product category has defined Essential Requirements (ERs) covering safety, EMC, radio spectrum efficiency, network compatibility, and security. These are published by TEC in the form of Interface Requirements (IR) documents and Essential Requirements Specifications (ERS). Your product must be tested and evaluated against all applicable ERs for its category. Identifying the correct ER set upfront determines which CAB is qualified to certify your product and what testing is required.

💡 Download the latest version of the applicable IR and ERS from tec.gov.in before engaging a CAB. TEC updates these documents periodically, and a CAB working from an outdated ER set may produce a test report that TEC rejects during certificate registration. Confirm the document version with TEC's MTCTE helpdesk if there is any doubt.
2
Select a TEC-Empanelled Conformity Assessment Body (CAB)

TEC maintains an empanelled list of CABs authorised to certify products for specific equipment categories. Not all CABs are authorised for all product categories — a CAB empanelled for mobile handsets may not be authorised for enterprise switches or optical transmission equipment. Shortlist CABs based on their authorisation scope, geographic location, current turnaround time, and track record with TEC certificate registration. Request quotes and timelines from at least two CABs before committing.

💡 Ask each shortlisted CAB how many TEC certificate applications they have pending with TEC at the time you engage them. A CAB with a large backlog will slow your timeline even if their internal testing is fast. Turnaround visibility is as important as testing competence when selecting a CAB.
3
Submit Application and Technical Documentation to the CAB

Prepare and submit the full technical documentation package to your selected CAB — including product description, technical specifications, circuit diagrams, bill of materials for safety-critical components, existing certifications (FCC, CE, PTCRB), test reports from accredited labs, and the authorisation letter appointing the Indian applicant as the manufacturer's representative. The CAB reviews the documentation, identifies any gaps, and proceeds to product testing once the package is complete.

💡 Attach your FCC or CE test reports even if the applicable Indian standards differ — CABs frequently use existing test data to identify which additional tests are needed specifically for MTCTE, reducing the overall testing scope and cost. Never assume existing reports are useless without having a CAB assess them first.
4
Product Testing Against Essential Requirements

The CAB conducts or coordinates testing of your product against all applicable Essential Requirements. Some CABs have in-house test facilities; others outsource specific tests to TEC-recognised laboratories. Testing covers electrical safety, electromagnetic compatibility (EMC), radio performance (if applicable), network interface compliance, and cybersecurity requirements introduced for certain product categories from 2024 onwards. Physical product samples — typically 2 to 3 units — must be provided to the CAB for testing.

💡 Cybersecurity requirements are the newest and least-understood addition to MTCTE's Essential Requirements for networking equipment. Products like routers, switches, and access points now need to demonstrate compliance with TEC's cybersecurity guidelines — including secure boot, firmware update authentication, and default credential policies. Flag this to your CAB upfront so testing scope is set correctly from the start.
5
CAB Issues Certificate and Registers on TEC Tarang Portal

Once testing is complete and all Essential Requirements are satisfied, the CAB issues a TEC certificate for the product. The certificate is then registered on TEC's Tarang portal, where it becomes publicly searchable. The certificate number must be marked on the product label, packaging, and commercial documentation. Without portal registration, the certificate cannot be verified by customs or market surveillance teams — making physical presence of the certificate alone insufficient for compliance proof.

💡 Verify the certificate registration on the Tarang portal yourself — do not rely solely on the CAB's confirmation that registration is done. Portal registration errors or delays have occasionally left companies with a valid CAB certificate that is not yet searchable, causing unnecessary customs queries at the point of import.
6
Apply for BIS CRS Registration in Parallel

For products that require both TEC MTCTE and BIS CRS — which includes mobile phones, Wi-Fi routers, set-top boxes, and most consumer networking devices — the BIS CRS application should be initiated simultaneously with the MTCTE process, not sequentially. BIS will accept the MTCTE certificate as supporting documentation, and running both processes in parallel typically saves 4 to 8 weeks compared to completing MTCTE first and then starting BIS CRS. This parallel track approach is standard practice at Siacc India for all dual-regulated products.

💡 BIS CRS and TEC MTCTE use different laboratory networks and different test standards — a test report prepared for one certification does not directly substitute for the other. However, certain test results (electrical safety, EMC) may be reusable across both if the applicable standards have sufficient overlap. Have Siacc India assess your existing test data for cross-utilisation before commissioning fresh testing for each certification independently.

Realistic MTCTE timeline: CAB selection and engagement — 3 to 5 working days. Technical documentation review by CAB — 5 to 10 working days. Product testing — 15 to 30 working days depending on product complexity and cybersecurity scope. CAB review and certificate issuance — 7 to 15 working days. TEC Tarang portal registration — 2 to 5 working days. Total for a straightforward product: 35 to 55 working days. Complex infrastructure equipment: 75 to 90 working days.

Documents Required for TEC MTCTE Certification

MTCTE documentation requirements are technically heavier than most other Indian product certifications — this reflects TEC's engineering-rigour approach to telecom equipment assessment. The CAB will not begin testing until the technical documentation package is complete and reviewed. Submitting incomplete documentation is one of the most common reasons MTCTE timelines extend to 90 days or more — a gap that surfaces only after the CAB has held your samples for two weeks and then requests missing material.

Mandatory Technical Documents

  1. Product Technical Specification Document — comprehensive description of the equipment covering hardware architecture, software/firmware version, interface specifications, frequency bands used, transmit power levels, and supported protocols and standards
  2. Circuit Diagrams and Block Diagrams — detailed schematics showing power supply design, RF front-end (if applicable), processor and memory architecture, and all external interface connections; must be on manufacturer letterhead
  3. Bill of Materials (BOM) for Safety-Critical Components — listing safety-relevant components such as capacitors, fuses, transformers, and switching devices with manufacturer part numbers and safety ratings
  4. Existing Type Approval or Certification Reports — FCC Part 15/22/24, CE RED/LVD/EMC, IC Canada, or any other national type approval that covers performance parameters relevant to the MTCTE Essential Requirements
  5. User Manual and Installation Guide — English version, covering product installation, operating parameters, safety warnings, and interface specifications for the end user and network operator
  6. Firmware Version Declaration — written declaration from the manufacturer specifying the exact firmware version being certified; any subsequent firmware change that affects Essential Requirements requires re-certification
  7. Declaration of Conformity — signed statement from the manufacturer affirming that the product meets all applicable Essential Requirements and that the technical documentation is accurate and complete

Commercial and Entity Documents

  • Authorisation Letter — appointing the Indian applicant (manufacturer's representative or AIR) to apply for TEC MTCTE on the foreign manufacturer's behalf; notarised for foreign manufacturers, apostilled where required by the CAB
  • GST Registration Certificate and PAN of the Indian applicant entity
  • IEC (Importer Exporter Code) for products being imported into India post-certification
  • Sample Invoice or Pro-Forma Invoice showing product model number, description, and commercial value — used by the CAB to verify the commercial identity of the product being certified

Firmware version lock warning: TEC MTCTE certificates are issued for a specific firmware version of the product. If your product receives an over-the-air firmware update post-certification that modifies radio behaviour, interface protocols, or security features — even a minor update — TEC's framework requires re-assessment. Selling the updated firmware version under the original certificate is a compliance violation. Build a firmware change notification process into your product development workflow from day one.

MTCTE vs BIS CRS: What Most Companies Get Dangerously Wrong

This is the section that could save your company from a very expensive customs or market surveillance problem. In India's electronics compliance landscape, TEC MTCTE and BIS CRS are two completely separate certification obligations that frequently apply to the same product simultaneously — administered by different authorities, tested against different standards, through different laboratory and CAB networks, with different timelines and fee structures. They are not interchangeable, and completing one does not reduce, waive, or substitute for the other. Yet a significant number of electronics importers and manufacturers treat them as if they overlap — and pay the price.

Products That Require Both TEC MTCTE and BIS CRS

  • Mobile phones and smartphones — TEC MTCTE under the mobile handset category, BIS CRS under IS 13252 for IT equipment safety, and WPC ETA for wireless modules — all three are mandatory simultaneously
  • Wi-Fi routers and home broadband gateways — TEC MTCTE for network interface compliance, BIS CRS under IS 13252, and WPC ETA for the Wi-Fi module
  • Enterprise switches and access points — TEC MTCTE mandatory from 2023, BIS CRS mandatory under IT equipment category
  • Set-top boxes and streaming media devices — TEC MTCTE for the broadcast and network interface, BIS CRS for the consumer electronics safety standard
  • Smart meters with telecom connectivity — TEC MTCTE for the communication module, BIS CRS under the smart meter standard, and WPC ETA for the wireless module if applicable

Why Companies Get Caught

The most common failure pattern is sequential thinking applied to a parallel compliance requirement. A company completes BIS CRS for their Wi-Fi router — a process that takes 60 to 90 days — and then discovers that TEC MTCTE was equally mandatory and now needs another 45 to 75 days. The product launch is delayed by months, warehouse storage costs accumulate, and in the worst cases, products already sold before MTCTE was obtained are subject to market recall notices from DoT. Running BIS CRS and TEC MTCTE in parallel — which Siacc India does as standard practice for dual-regulated products — typically compresses the combined timeline to 75 to 90 days rather than 120 to 160 days sequentially.

The test data overlap opportunity is also frequently missed. For products like routers and switches, BIS CRS testing under IS 13252 covers electrical safety parameters that partially overlap with MTCTE's Essential Requirements for the same safety domain. A well-structured testing programme — where the lab produces a single integrated test report that satisfies both BIS CRS and the safety component of MTCTE — can reduce total testing cost by 25 to 40% compared to commissioning fully separate test programmes for each certification. This requires upfront planning and a compliance consultant who understands both schemes, but the savings are material for companies with multiple product models.

Siacc India's dual-compliance programme for telecom products: we assess your product's certification requirements across TEC MTCTE, BIS CRS, and WPC ETA simultaneously, identify test data overlap opportunities, build a single integrated compliance calendar, and manage all three certification tracks in parallel — so you get all required certificates in one coordinated programme rather than three sequential projects with three separate timelines.

TEC MTCTE Certification: Realistic Costs and Timeline in 2025

MTCTE costs are higher than most other Indian product certifications — reflecting the technical depth of the Essential Requirements assessment and the CAB's professional service component. Unlike BIS CRS where government fees are modest and the main cost is laboratory testing, MTCTE involves significant CAB professional fees on top of testing costs. Companies that budget for MTCTE based on BIS CRS cost benchmarks consistently find themselves with budget shortfalls mid-process. The ranges below are based on actual 2025 market rates across TEC-empanelled CABs for the most common product categories.

CAB Certification Fees

CAB fees for MTCTE certification cover document review, testing coordination, Essential Requirements evaluation, and certificate issuance. For simpler products like enterprise switches and access points, CAB fees typically range from ₹80,000 to ₹1,50,000. For more complex products such as mobile handsets, broadband gateways, or optical transmission equipment — which have broader Essential Requirements scope and more extensive testing — CAB fees range from ₹1,50,000 to ₹3,50,000 per model. Products requiring cybersecurity assessment attract an additional ₹50,000 to ₹1,00,000 for the cybersecurity evaluation component.

Testing Costs

Where existing FCC, CE, or other international test reports cover a significant portion of the MTCTE Essential Requirements, additional testing costs are limited to India-specific parameters not covered by existing reports — typically ₹30,000 to ₹80,000. Where fresh testing is required from scratch, costs range from ₹1,00,000 to ₹4,00,000 depending on the product category, number of interface types, and whether RF and cybersecurity testing are included.

Certificate Validity and Renewal

TEC MTCTE certificates are valid for a period of 3 years from the date of issuance — a significantly longer validity than BIS CRS's annual renewal cycle. Renewal requires resubmission through the CAB, with testing scope determined by whether the product specifications have changed during the validity period. If the hardware and firmware are unchanged, renewal testing can often be limited to interface compliance verification rather than a full re-test, reducing renewal costs considerably.

Multi-model cost strategy: if you have a product family where multiple models share the same hardware platform and differ only in software features or external form factor, request a family certification assessment from your CAB. TEC allows family certification approaches for products with a common core architecture — one certification covering the base platform with documented model variants can reduce CAB fees and testing costs by 35 to 50% compared to individual model applications.

How Siacc India Manages Your TEC MTCTE and BIS CRS Together

Siacc India's approach to TEC MTCTE is built around one core principle: no electronics or telecom product entering the Indian market should go through certification sequentially when parallel processing is possible. Our compliance team assesses every product's full Indian certification landscape — TEC MTCTE, BIS CRS, WPC ETA, and any other applicable requirements — before a single document is prepared or a single test is commissioned. This upfront mapping exercise, which takes 24 to 48 hours for most products, eliminates the sequential-process trap that costs companies months of avoidable delay.

  • Full multi-certification mapping within 48 hours: for any telecom or networking product, we identify every applicable Indian certification, the correct CAB and lab for each, the applicable standards, and the test data overlap opportunities — delivered as a clear compliance roadmap with timelines and costs before you commit to any process
  • CAB selection and engagement management: we maintain active working relationships with TEC-empanelled CABs across all major product categories, enabling us to select the CAB with the best current turnaround time for your specific product and negotiate priority processing where needed
  • Integrated BIS CRS and MTCTE programme: for dual-regulated products, our team manages both certification tracks simultaneously — same project manager, coordinated timelines, shared test data where applicable — so you receive both certificates in the shortest possible combined timeline
  • Cybersecurity compliance preparation: TEC's cybersecurity requirements for networking equipment are new enough that most CABs are still building their assessment processes; our technical team prepares your product's cybersecurity documentation ahead of CAB engagement, preventing this component from becoming a bottleneck
  • Post-certification firmware change management: we maintain records of your certified firmware versions and notify you when product updates require re-assessment — preventing the common violation of shipping updated firmware under an original certificate

For companies entering the Indian market with their first telecom or networking product, the combined weight of TEC MTCTE, BIS CRS, and WPC ETA can feel overwhelming — three separate regulatory frameworks, three different authorities, three different laboratory networks, and three different timelines all running simultaneously. Siacc India's value in this situation is not just managing the paperwork — it is giving you a single coordinated programme with one timeline, one point of contact, and one clear outcome: all required certificates in hand before your product reaches Indian shores.

Start with a free multi-certification assessment: share your product datasheet with the Siacc India team and receive a complete Indian compliance map — covering TEC MTCTE, BIS CRS, WPC ETA, and any other applicable requirements — with timelines, costs, and test data reuse opportunities, within 24 working hours.
