In today’s fast-changing telecom industry, failing to comply with the national standards is not just a regulatory concern but also an economic concern. Of all approvals, TEC certification remains the most important for a manufacturer or importer of telecom equipment whose products are to be sold in the Indian territory. The Telecommunication Engineering Centre, under the Department of Telecommunications, issues a TEC certification, which ensures that telecom equipment meets basic requirements about safety, electromagnetic compatibility (EMC), and technical specifications.
We at Diligence Certification ease the oftentimes challenging procedure of getting TEC certification for businesses so they can get faster compliance and market access. This blog is a complete one about everything and anything you need to know about TEC certification: different modes of voluntary testing certification, mandatory testing, and certification of telecom equipment (MTCTE), products covered under different phases, documentation requirements, and how Diligence Certification can assist you.
Introduction to TEC Certification
In India, TEC certification is required for all telecom equipment that is manufactured, imported, sold, or used. This certification assures that the equipment meets essential requirements (ERs) regarding safety, EMC, and other technical parameters; without TEC certification, telecom products cannot legally be sold or connected to public networks in India.
For manufacturers, importers, and traders striving to make their mark on the Indian telecom scene, TEC certification is a critical opening through which they need to pass. Much in the way we assist all types of companies in getting their TEC certification with a minimum hiccup, Diligence Certification is your partner in an oftentimes confusing compliance maze.
Types of Voluntary Testing Certification
Apart from mandatory certification, TEC provides voluntary testing certification for telecom products for quality assurance and standardization. The authority has four main types of voluntary certifications:
1. Type Approval
This is granted when the product conforms to the Generic Requirements (GRs) laid down by TEC. It ensures that the product meets the minimum standards for quality and performance.
2. Interface Approval
Interface Approval certifies that the telecom equipment conforms to the Interface Requirements (IRs) to interoperate with other network equipment.
3. Certificate of Approval (CoA)
If the product is not covered under any existing GR or IR, then the manufacturer may apply for a Certificate of Approval (CoA) under its own specifications, which are then evaluated by TEC.
4. Technology Approval
This is an approval for prototype telecommunication products developed by R&D institutions to ensure they meet technical standards so that they can be taken up for mass production.
Obtaining voluntary TEC certification under any of the above-mentioned categories can help manufacturers prove the quality of their products, despite this being not legally binding.
Products Under TEC Approval




A wide range of telecom products requires TEC certification to ensure safety, interoperability, and technical compliance. Some common products under TEC certification include:
- Routers
- Switches
- Optical Transport Equipment
- Network Interface Devices
- PON Equipment (OLTs, ONUs)
- Feedback Devices
- Base Stations
- Smart Meters
- Tracking Devices
At Diligence Certification, we help businesses identify whether their product falls under the scope of TEC certification and guide them through the approval process.
Mandatory Testing and Certification of Telecom Equipment (MTCTE)
Mandatory Testing and Certification of Telecom Equipment (MTCTE) was established under the Indian Telegraph (Amendment) Rules, 2017. According to this issue, before any telecom equipment could be sold or used in India, it had to be mandatorily tested and certified.
The testing shall be carried out in laboratories designated by the TEC or recognized Conformance Assessment Bodies (CABs). Certification will be granted only to products that conform to the Essential Requirements (ERs) prescribed by TEC.
Without the TEC-issue certification under MTCTE, telecom products cannot be connected to public telecom networks in India. Diligence Certification helps your products meet these requirements and assists you in obtaining the certification in the quickest possible manner.
