India: BIS (CRS), TEC (MTCTE) and WPC (ETA) certifications

Hugues Orgitello updated 7 Oct 2026 16 min read

There is no single Indian conformity mark for electronics. Three tracks run on three different texts: the Compulsory Registration Scheme (CRS) of the Bureau of Indian Standards, set by a MeitY order under the BIS Act 2016; the Mandatory Testing and Certification of Telecom Equipment (MTCTE) run by the Telecommunication Engineering Centre, now under section 19 of the Telecommunications Act 2023; and the Equipment Type Approval (ETA) of the WPC Wing for radio equipment in licence-exempt bands. This page reads each track from its gazette notifications and procedures, with the 2024 to 2026 changes: the move from IS 13252 to IS/IEC 62368-1:2023, the 2025 telecom conformity rules, MTCTE Phase VI, ten-year MTCTE certificates and the opening of the lower 6 GHz band to licence-exempt use. The link with IEC standards is shown where the Indian Standard adopts one.

Which track applies

Each track is triggered by a list, not by a product type in general. A product enters CRS only if it appears in the Schedule of the 2021 Order, MTCTE only if its equipment category has been notified with an Essential Requirement, and ETA if it contains a radio working in a band exempted from licensing.

Track	Legal basis	Authority	Trigger	Output
BIS CRS	Electronics and IT Goods (Requirement of Compulsory Registration) Order, 2021, S.O. 1248(E), under sections 16 and 25(3) of the BIS Act 2016	BIS certifies and enforces; MeitY notifies the Schedule	Goods listed in the Schedule	Licence to use the Standard Mark under Scheme-II (registration)
TEC MTCTE	Section 19 of the Telecommunications Act 2023 and G.S.R. 315(E) of 16 May 2025, which supersedes rules 528 to 537 of the Indian Telegraph Rules 1951	TEC and NCCS (both Appropriate Authorities)	Equipment notified under an MTCTE phase	MTCTE certificate per model, TEC label
WPC ETA	Band exemption rules, such as G.S.R. 45(E) of 28 January 2005 for 2.4 GHz and G.S.R. 47(E) of 20 January 2026 for the lower 6 GHz band	WPC Wing, Department of Telecommunications	Radio equipment in a licence-exempt band	ETA certificate, generated by self-declaration for eligible products

A Wi-Fi access point illustrates the overlap: its power adaptor falls under CRS (entry 16, power adaptors for IT equipment), Wi-Fi access points and CPE have been under MTCTE since 1 January 2024 (Phase 3), and the radio needs an ETA. A BLE wearable may need CRS (smart watches are entry 44) and ETA, but no MTCTE if its category was never notified.

BIS Compulsory Registration Scheme

The 2021 Order and its Schedule

MeitY published the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, 2021 on 18 March 2021 (S.O. 1248(E)). It applied six months after publication and runs concurrently with the 2012 Order: registrations granted under 2012 remain valid and are renewed under 2021. Paragraph 2 obliges the listed goods to conform to the Indian Standard in the Schedule and to bear the Standard Mark under a licence granted under Scheme-II of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Goods made for export to a foreign buyer's specification are excluded, and MeitY may exempt specific products by written decision.

The Schedule is the scope. Extract of the entries most relevant to connected products:

Entry	Goods	Indian Standard in the Schedule
2	Laptops, notebooks, tablets	IS 13252 (Part 1):2010
14	Set top boxes	IS 13252 (Part 1):2010
16	Power adaptors for IT equipment	IS 13252 (Part 1):2010
17	Power adaptors for audio, video and similar apparatus	IS 616:2017
19	DC or AC supplied electronic control gear for LED modules	IS 15885 (Part 2/Sec 13)
20	Sealed secondary cells and batteries for portable applications	IS 16046 (Part 1 and Part 2):2018
21	Self-ballasted LED lamps	IS 16102 (Part 1):2012
23	Mobile phones	IS 13252 (Part 1):2010
30	Power banks	IS 13252 (Part 1):2010
41	CCTV cameras and CCTV recorders	IS 13252 (Part 1):2010
44	Smart watches	IS 13252 (Part 1):2010
51	Wireless headphones and earphones	IS 616:2017
54	Standalone SMPS with output voltage up to 48 V	IS 13252 (Part 1):2010
61	Smart speakers (with and without display)	IS 616:2017 (after the corrigendum S.O. 1353(E))
63	Bluetooth speakers	IS 616:2017

The Schedule note makes the latest version of each Indian Standard, with its amendments, applicable from the date notified by BIS. That is how the IS 13252 family is being replaced.

Amendments that changed the scope (2021 to 2026)

Date	Notification	Change
25 March 2021	S.O. 1353(E)	Corrigendum: entry 61 (smart speakers) moves to IS 616:2017
1 July 2021	S.O. 2844(E)	Paragraphs 6 to 8: deferral for new factory locations, three months to affix the mark at ports, exemption for highly specialised equipment
26 April 2023	S.O. 1929(E)	Entry 64, television sets to IS 18112:2022, applicable after two years
9 April 2024	S.O. 1652(E)	Essential Requirement(s) for Security of CCTV added for CCTV cameras, applicable six months after publication
22 September 2025	S.O. 4362(E)	Television sets: date moved from 26 October 2025 to 26 January 2026
29 October 2025	S.O. 4997(E)	IS 13252 (Part 1):2010 and IS 616:2017 migrate to IS/IEC 62368-1:2023; entry 65, extended reality products
22 January 2026	S.O. 352(E)	Further amendment (listed in the May 2026 notification)
5 May 2026	S.O. 2204(E)	Entry 50 becomes "Standalone Hard Disk Drives", applicable to all standalone HDDs from 5 November 2026

The amendment notes also cite S.O. 4378(E) of 9 October 2024, S.O. 1363(E) of 20 March 2025 and S.O. 1246(E) of 10 March 2026. The television date has already been deferred once (S.O. 4362(E)); check the latest notification before relying on any date.

IS 13252, IS 616 and IS/IEC 62368-1:2023

IS 13252 (Part 1):2010 follows the IEC 60950-1 structure and IS 616:2017 covers audio and video apparatus. Under S.O. 4997(E), both give way to IS/IEC 62368-1:2023, the Indian adoption of IEC 62368-1. The concurrent running period lasts until 1 November 2028 for the goods concerned; for extended reality products it ended on 1 May 2026. A manufacturer registering a new model in 2026 can therefore still test to IS 13252 or IS 616, but every registration will need IS/IEC 62368-1:2023 after the concurrent period.

Testing, registration and validity

The BIS CRS FAQ fixes the practical rules:

• Laboratory: only reports from BIS recognised laboratories against the notified Indian Standard are accepted. CE, UL, FCC or CB test reports do not replace them, a supplier's report is not acceptable for an importer, and manufacturers' own laboratories cannot be recognised.
• Report age: the test report must not be older than 90 days on the date of the online application.
• Scope of a registration: the registration number is linked to the manufacturer, the factory location, the product and the brand. Each additional factory needs its own application; additional brands can share a test report if product and factory are identical.
• Changes: pre-certified safety critical components of the same rating may be substituted with an intimation to BIS; a circuit, design or component change requires retesting.
• Validity: Scheme-II grants the licence for two years initially and renews it for two to five years. Scheme-II asks for the renewal application three months before expiry; the 2022 FAQ still says one month, so the regulation is the safer reference.

Exemption for highly specialised equipment (paragraph 8): fewer than 100 units per model per year, and either three-phase supply, single-phase above 16 A, dimensions over 1.5 m x 0.8 m, or weight over 80 kg.

Marking

Under paragraph 6 of Scheme-II, the product or its package (or both) carries the Standard Mark with the licence number and the Indian Standard number, plus a reference to the BIS website (www.bis.gov.in) so that buyers can check authenticity. The BIS FAQ asks for the mark on both product and packaging, with packaging only when the product is too small. Devices with an integrated display may show the mark electronically (e-labelling), but BIS still requires the website reference to be marked physically. Lettering must not be smaller than Arial size 6.

CRS is Scheme-II. The ISI mark is a different BIS certification used by other quality control orders, and Hallmarking is a separate BIS scheme for precious metals; both appear as distinct schemes on the BIS website. None of them substitutes for another.

TEC MTCTE

From the Telegraph Rules to the Telecommunications Act

MTCTE started with Part XI of the Indian Telegraph Rules, 1951 (rules 528 to 537, inserted by G.S.R. 1131(E) of 5 September 2017). The procedure came into force on 1 October 2018 and the first products became mandatory on 1 October 2019. On 16 May 2025, G.S.R. 315(E) made the Telecommunications (Framework to Notify Standards, Conformity Assessment and Certification) Rules, 2025 under section 19 of the Telecommunications Act 2023. They supersede rules 528 to 537 but keep existing Essential Requirements, ITSAR documents and exemptions in force until replaced. Key provisions:

• TEC and the National Centre for Communication Security (NCCS) are the Appropriate Authorities (rule 4).
• Draft standards must be published for at least 60 days of consultation and reviewed at least every five years (rule 5).
• An authority may recognise a laboratory in India or, in the public interest, an ILAC-accredited laboratory in another country, except countries that share a land border with India (rule 6).
• No equipment to which a standard applies may be sold, deployed or used without a valid Certificate of Conformity Assessment (rule 8).
• R&D, demonstration, testing and personal-use imports are exempt; no recertification is needed when model and brand are unchanged (rule 9).
• A person found with uncertified equipment must stop within seven days and can regularise within 180 days by paying ten times the fee (rule 12).

Phases and mandatory dates

Phase	Mandatory certification date (TEC Annexure-I, July 2024)	Examples of equipment
1	1 October 2019	2-wire telephones, G3 fax, modems, cordless telephones, ISDN CPE, PBX
2	1 October 2020	PON OLT/ONT/ONU, feedback devices, SDH and multiplexing equipment
3	1 January 2024 to 1 October 2024	Wi-Fi access points and CPE, PTP/PMP wireless access at 2.4 or 5 GHz, WLAN controllers, IoT gateways, tracking devices (1 January 2024); cellular repeaters (1 April 2024); 2G to 4G base stations (1 August 2024); smart electricity meters (1 October 2024)
4	1 January 2024 to 1 October 2024	Conferencing equipment, HF radio, VHF/UHF radio, mobile radio trunking, LAN switches, routers, SIM, eSIM and eUICC, PTP/PMP microwave
5	1 July 2024 and 1 October 2024	5G core functions, E-band radio relay (July); 5G base stations, hypervisors, SIP terminals (October)
VI	180 days after S.O. 982(E) of 25 February 2025	Cellular customer premises equipment, fixed wireless phones, SAN and fabric interconnect switches, network security equipment and firewalls, NGSO satellite user terminals and gateways

Phase VI is the first phase notified under section 19 of the Telecommunications Act 2023.

Essential Requirements, schemes and laboratories

The MTCTE Procedure v3.0 (TEC 93009:2024) defines the Essential Requirements as EMI/EMC, safety, technical requirements, security requirements set by DoT or NCCS, and other requirements. ERs reference international documents, often ETSI EN and 3GPP specifications. Unlike an EU harmonised standard, which is voluntary and gives a presumption of conformity, an ER is the mandatory test scope.

• General Certification Scheme (GCS): base stations, repeaters, radio systems, satellite equipment; TEC evaluates the reports; certificate normally within 4 to 8 weeks of complete reports.
• Simplified Certification Scheme (SCS): the other categories, including equipment operating in the 2.4 GHz and 5 GHz bands, IoT gateways, routers and LAN switches; reports are not evaluated by TEC; certificate normally within fifteen working days.
• Laboratories: testing in TEC designated conformity assessment bodies, with reports not older than five years. ILAC-accredited reports are accepted only as time-bound relaxations; on 30 June 2026 TEC extended ILAC acceptance to 31 December 2026 for some base station variants, SIM, VHF/UHF radio and E-band radio relay, from non-border-sharing countries, with reports not older than two years.
• Safety: a valid BIS certificate or a safety report from a BIS recognised laboratory is accepted for the safety part of the ER (clause 5.8).
• Scope limit: only complete, standalone equipment is certified. Modules and components are not covered, and systems made of several pieces of equipment are certified piece by piece (clause 5.4, amended 19 September 2024).

Security: ITSAR and NCCS

The ITSAR documents (Indian Telecom Security Assurance Requirements) are issued by NCCS in Bengaluru. The procedure makes security part of the ER and lets TEC or NCCS notify the date from which a category must be certified against its ITSAR; an integrated certificate is then issued for ER and ITSAR. For IP routers and Wi-Fi CPE, an NCCS notification of 2 October 2024 accepted applications until 31 October 2024 with a self-declaration of conformance to the ITSAR and issued "Pro Tem" certificates valid six months.

Certificate, validity and label

A certificate covers one model, for any quantity; associated models and family configurations can be certified without retesting. Procedure v3.0 raised the validity of a regular certificate from five to ten years; provisional certificates, issued when some parameters are exempted, are valid two years. The OEM, or the AIR for a foreign OEM, must mark the equipment with the brand, model and serial number and the TEC certification label (TEC logo with MTCTE followed by the certificate number). An e-label is allowed on devices with an integrated display, with a physical label on the packaging. Labelling is waived for six months from the mandatory date or from the certificate date, whichever is later.

WPC Equipment Type Approval

ETA through self-declaration

The WPC Wing generates ETA through self-declaration under office memorandum ETA-WPC/Policy/2018-19 of 26 February 2019. A generated certificate shows how it works: the applicant is the Indian manufacturer or the authorised Indian representative of the foreign manufacturer; it lists frequency ranges, maximum output power and the applicable gazette notification; the RF test report can come from an accredited foreign laboratory; and the certificate is self-generated, without signature, and verifiable on the Saral Sanchar portal. Its conditions:

• it is valid only for equipment exempted from import licensing under the DGFT import policy;
• use is on a non-interference, non-protection, non-exclusive basis under the cited band notification;
• it is no longer valid if the declared parameters change;
• WPC field units may take samples for RF checks;
• a false declaration or a non-genuine test report exposes the applicant to prosecution;
• once generated for a model, it can be used by others to import that model.

The certificate examined carries no expiry date. Equipment outside these conditions does not qualify for the self-declaration route.

Licence-exempt bands

Each band is opened by its own rules, which set power, bandwidth and use conditions. G.S.R. 45(E) of 28 January 2005 covers the 2.4 GHz ISM band used by Wi-Fi and Bluetooth; the 5 GHz RLAN bands are opened by separate notifications. The newest is the lower 6 GHz band:

Parameter (G.S.R. 47(E), in force 21 January 2026)	Low power indoor	Very low power outdoor
Band	5925 to 6425 MHz	5925 to 6425 MHz
Maximum EIRP	30 dBm	14 dBm
Maximum PSD	11 dBm/MHz	1 dBm/MHz
Maximum emission bandwidth	320 MHz	320 MHz
Out-of-band emissions	-27 dBm/MHz	-27 dBm/MHz

Further conditions: no use on oil platforms; no indoor use in land vehicles, boats or aircraft below 10,000 feet; no communication with or control of drones; a contention-based protocol; an in-built antenna; and type approval. These rules were made under the Indian Telegraph Act 1885 and the Indian Wireless Telegraphy Act 1933, although the 2025 conformity rules already rest on the Telecommunications Act 2023.

SACFA

Clearance by SACFA (Standing Advisory Committee on Frequency Allocation) concerns the siting of transmitting stations such as masts and antennas. It is an installation clearance for network operators and infrastructure, not an approval of a consumer device.

Applicant, testing and validity across the three tracks

	BIS CRS	TEC MTCTE	WPC ETA (self-declaration)
Applicant for a foreign manufacturer	Manufacturer with its Authorised Indian Representative	AIR, a company or firm incorporated in India	Authorised Indian representative
Accepted test reports	BIS recognised laboratory only, against the IS	TEC designated CAB; ILAC reports only under time-bound relaxations	RF report from an accredited laboratory, foreign ones included
Maximum report age	90 days	Five years (two years for ILAC relaxations)	Not stated on the certificate
What is certified	Product, brand and factory location	Model (plus associated models and families)	Model and declared radio parameters
Validity	Two years, renewal for two to five years	Ten years (regular), two years (provisional)	No expiry date on the certificate
Mark	Standard Mark with IS number and licence number, BIS website	TEC logo, MTCTE and certificate number	No marking condition on the certificate

Coming from CE or FCC, nothing transfers automatically. A CE file built on RoHS, LVD and RED, or an FCC grant from a TCB, is not an Indian certificate. The RF test report behind them can support an ETA if it comes from an accredited laboratory, while CRS testing has to be repeated in a BIS recognised laboratory. For the EU and US side, see CE vs FCC and parallel EU and US certification.

Claims the texts contradict

Common claim (some made by earlier versions of this page)	What the texts say
CRS is notified by MeitY under the Information Technology Act	The 2021 Order is made under sections 16 and 25(3) of the BIS Act 2016
CRS uses an IS transposition of IEC 60950 or IEC 62368 depending on the product	The Schedule cites IS 13252 (Part 1):2010 and IS 616:2017; S.O. 4997(E) moves both to IS/IEC 62368-1:2023, with concurrent running until 1 November 2028
IS 15885 covers self-ballasted LED lamps	Self-ballasted LED lamps are entry 21 under IS 16102 (Part 1):2012; IS 15885 (Part 2/Sec 13) covers LED control gear (entry 19)
A CRS registration number has the form R-XXXXXXXXXX	The texts only require the licence number and the IS number with the Standard Mark; no format is fixed in the sources read here
MTCTE Phase 1 became mandatory in late 2018, and Phase 5 is the latest	The procedure came into force on 1 October 2018, but Phase 1 products became mandatory on 1 October 2019; Phase VI was notified on 25 February 2025
MTCTE rests on amendments to the Indian Telegraph Rules	Since 16 May 2025 it rests on section 19 of the Telecommunications Act 2023 and G.S.R. 315(E), which supersede rules 528 to 537
The MTCTE certificate is referenced in the technical documentation	The equipment carries the TEC logo, MTCTE and the certificate number (clause 9.1)
MTCTE certificates last five years	Procedure v3.0 raised regular certificates to ten years; provisional ones last two
MTCTE testing must happen in Indian laboratories	Designated CABs are the rule; ILAC reports are accepted under time-bound relaxations, and the 2025 Rules allow recognition of foreign ILAC laboratories outside land-border countries
WPC reviews the ETA technical file	The self-declaration certificate is generated by Saral Sanchar without signature; WPC field units can audit afterwards
A wireless router needs CRS for its mains supply	Routers are not in the CRS Schedule; their external power adaptor is (entry 16)
The 2025 telecom rules define the Authorised Indian Representative	The AIR definition appeared in the draft G.S.R. 82(E) of 29 January 2025 but not in the final G.S.R. 315(E); the AIR is defined by the MTCTE procedure
Hindi labelling is required on top of English	None of the CRS, MTCTE or ETA texts read here imposes a language for the mark

Step by step for a connected product

1. Map the lists: CRS Schedule entry and its Indian Standard, MTCTE category and ER (check the MTCTE portal), and the band rules for each radio.
2. Appoint the Indian representative under a written authorisation; MTCTE asks for the authorisation and the agreement between the foreign OEM and the AIR at registration.
3. CRS: test in a BIS recognised laboratory to the current IS, file within 90 days of the report, then affix the Standard Mark with IS and licence numbers.
4. MTCTE: test in TEC designated CABs, reuse the BIS safety certificate for the safety part, add the ITSAR certification where notified, apply on the MTCTE portal, then label with TEC, MTCTE and the certificate number.
5. ETA: upload the accredited RF test report on Saral Sanchar for each model and check the declared frequencies and power against the band rules.
6. Plan changes: a CRS design change needs retesting; an MTCTE model with different hardware or software is a new model; an ETA is void if its declared parameters change.
