What is TEC Certification for India?


Telecommunication Engineering Center (TEC) is the authority in India responsible for the certification for telecommunication products in accordance with the Mandatory Testing Certification of Telecommunication Equipment (MTCTE) regulations.

The Indian Telegraph Amendment Regulations of September 5, 2017 stipulate that all telecommunication equipment must undergo mandatory testing and certification before sale, import or use in India.

TEC’s scope of responsibilities includes the following tasks:

  • Issuance of standards related to telecommunications equipment and services.
  • Cooperation with multilateral organizations (for example International Telecommunication Union)
  • Working with the Department of Telecommunication (DoT), assisting with policy planning for the telecommunications sector.
  • Testing and certification of telecommunication products and issuance of certificates
  • Technical support of the DoT

Previously this was a voluntary certification, but was made mandatory in 2019. TEC has been converting the regulations step by step for the various product groups to the mandatory MTCTE. According to Indian law, the supply, sale and import of these products are only permitted once they have successfully obtained TEC certification.

Which products are covered by TEC registration?

Various products in the telecommunications sector fall under the TEC obligation. These include, for example:

  • IoT gateway
  • Modems
  • Cordless phones
  • DSL devices
  • Communication devices with microwaves
  • Executive phone systems
  • NSD / ISD coin phones
  • Electronic telephone instruments
  • Key telephone systems
  • Telephones with 2 lines
  • Pay phones
  • Terminals for connection to the public telephone network
  • CLIP phones
  • G3 fax machines
  • ISDN customer premises equipment (CPE)
  • Private automatic branch exchange (PABX)

Some products may require BIS certification in addition to mandatory TEC certification. There are also products for which TEC certification may be waived if BIS CRS registration is already available.

Products with Wi-Fi or other wireless communication will also need an additional WPC certification.

TEC Certification Process

Depending on the structure and complexity of the product, the following two certification groups are distinguished:

General Certification Scheme

In this group, test reports from an accredited laboratory must be submitted in addition to the application documents. With a few exceptions, almost all products for which TEC certification is required fall into this category.

Simplified Certification Scheme

In this group, a declaration must be submitted for TEC registration that the products meet the requirements of the TEC standards (Essential Requirements). Product testing is usually not required. Very few products currently fall under the Simplified Certification Scheme for TEC registration in India. These products are:

  • Fax machines
  • Telephones with two lines
  • Modems (connectable to 2-wire analogue line)
  • ISDN subscriber terminals

The Steps of a TEC Certification at a Glance:


Preparation of the application documents and application to TEC


Product testing in India according to MTCTE Guidelines


Submission of documents including test reports


Issuance of the certificate


Marking and labeling of the product

TEC certification requires product testing in an accredited laboratory in India. After evaluation of the results of the product testing, the certificate is issued. The certificate contains details of the applicant, the product and the applicable Indian norms and standards, as well as the date of issue.

Once you have the certificate, your certified products can be marked accordingly. So far, no factory inspections are required, but this may change in the future.

TEC Marking

Products must be marked with the TEC logo on the body of the device after certification is complete.

In addition, the following info must be provided:
“INDIA, Essential Requirement (ER) number, Model No. and Country of Origin”.


AIR (Authorized Indian Representative)

The application for TEC approval must always be made through an Authorized Indian Representative (AIR). This is a representative in India authorized by the manufacturer who will act as a local contact for the Indian authorities and is responsible for submitting applications.
