TEC Certification in India — Complete Guide for Telecom Equipment Manufacturers & Importers

If you manufacture or import telecom equipment for the Indian market, TEC Certification is one of the most critical regulatory requirements you need to address. Whether it is a telephone, a router, a VSAT system, a base station component, or any other product that connects to India's public telecom network — TEC approval is mandatory before your product can be legally sold or deployed.

TEC stands for Telecommunications Engineering Centre — the technical arm of India's Department of Telecommunications (DoT). TEC issues Interface Approvals and Equipment Type Approvals that confirm telecom products meet India's technical interface standards and performance specifications before they are permitted to connect to the public network.

At Ornate Quality Services, we have helped telecom equipment manufacturers and importers navigate the TEC certification process since 2013. This guide covers everything you need to know — what TEC certification is, which products require it, how the process works, what it costs, and how to avoid the delays that commonly hold up TEC applications.

What is TEC Certification?

Why TEC Certification Is Essential for Your Business

TEC Certification is not just a regulatory checkbox — it is a gateway to the Indian telecom market. Here is why getting TEC certified matters for your business.

Mandatory Under Indian Telecom Law

The Indian Telegraph Act and DoT's Mandatory Testing and Certification of Telecom Equipment (MTCTE) policy make TEC approval compulsory for all telecom equipment connected to Indian networks. Since 2021, DoT has significantly expanded the list of products under mandatory TEC certification and has strengthened enforcement at ports of entry and in the market. Non-compliant products are being actively recalled and penalised.

Required for Network Operators and Service Providers

Telecom operators in India — including Jio, Airtel, Vi, and BSNL — are required by DoT to use only TEC-certified equipment in their networks. If you supply equipment to telecom operators or infrastructure providers, TEC certification is a non-negotiable prerequisite. Without it, your product will not be considered for procurement regardless of its technical capabilities or pricing.

Customs Clearance for Imported Equipment

Since the expansion of the MTCTE policy, Indian customs authorities check for TEC certification for notified telecom product categories. Products imported without valid TEC approval are being held at ports, returned to origin, or destroyed. The financial and reputational cost of a customs hold on telecom equipment — which is often high-value — is significant.

Essential for Government and Institutional Buyers

Government departments, defence establishments, railways, and public sector undertakings that procure telecom equipment require TEC certification as a mandatory qualification criterion. If your business targets these buyers — or intends to in the future — TEC approval is essential from the outset.

Competitive Advantage in the Indian Telecom Market

India is one of the world's largest telecom markets. A TEC-certified product signals technical credibility, regulatory compliance, and a serious commitment to the Indian market. It differentiates your product from uncertified competitors and builds confidence with buyers, integrators, and network operators.

Which Products Require TEC Certification in India?

TEC certification under the MTCTE policy applies to a wide range of telecom and network equipment. The following table covers the most common product categories for which manufacturers and importers seek TEC approval.

The MTCTE policy list is updated periodically as DoT brings new product categories under mandatory certification. Our team monitors all DoT notifications and will confirm the current TEC certification requirements for your specific product during your free consultation.

TEC Certification Process — Step by Step

The TEC certification process under the MTCTE policy is structured but involves multiple agencies — TEC, designated test labs, and DoT's online portal. Here is a complete breakdown of every stage and how Ornate Quality Services manages the process for you.

TEC Certification Registration Requirements

Before applying for TEC Certification, manufacturers and importers must meet the following eligibility requirements.

For Indian Manufacturers

• Valid business registration in India — GST registration and company incorporation certificate
• Product must comply with the applicable TEC Interface Approval Standard or Equipment Type Approval specification
• Product samples available for testing at a TEC-empanelled laboratory
• Technical documentation demonstrating compliance with the applicable TEC standard
• Qualified technical personnel capable of supporting the testing process and responding to TEC queries

For Importers

• Valid Import Export Code (IEC) registered with DGFT
• Authorisation letter from the foreign manufacturer confirming the importer's right to certify and sell the product in India
• Product samples available for testing at a TEC-empanelled laboratory in India
• Complete technical documentation from the foreign manufacturer including interface specifications and block diagrams

For Foreign Manufacturers (Direct Application)

Foreign manufacturers can apply for TEC certification directly through the MTCTE portal or through an authorised Indian representative. Ornate Quality Services acts as the authorised representative for international manufacturers — managing the complete TEC application process in India on their behalf.

TEC Certification Cost — What to Expect

TEC certification involves several cost components. Understanding these upfront helps you plan your certification budget accurately.

TEC Application Fee

TEC charges a government application fee at the time of filing. The fee varies by product category and type of certification — Interface Approval or Equipment Type Approval. Application fees typically range from INR 5,000 to INR 25,000 depending on the product and the number of interfaces being certified.

Laboratory Testing Charges

Testing charges are paid directly to the TEC-empanelled laboratory. Costs vary significantly by product category and the number of parameters to be tested. For terminal equipment and networking devices, testing typically costs between INR 20,000 and INR 80,000 per product. Complex products with multiple interfaces or advanced features may cost more.

Annual Surveillance Fee

TEC charges an annual fee for maintaining the certification during its validity period. This covers TEC's ongoing surveillance activities and is typically a fraction of the initial application fee.

Professional Service Fees

Ornate Quality Services charges a fixed professional fee for end-to-end TEC certification management — from product classification and standard identification to lab coordination, application filing, query resolution, and certificate delivery. All fees are quoted transparently before we begin work.

TEC Certification Validity and Renewal

TEC certifications are typically issued with a validity period of three to five years, depending on the product category and the type of certification issued. The exact validity is specified on the certificate at the time of issue.

Renewal Process

TEC certification renewal must be initiated before the existing certificate expires. The renewal process involves filing a renewal application on the MTCTE portal, submitting updated documents, paying the renewal fee, and confirming that the product continues to conform to the applicable TEC standard.

If the product has undergone hardware or software changes since the original certification, fresh testing may be required as part of the renewal process. Our team assesses any product changes and advises on whether renewed testing is necessary before initiating the renewal application.

Standard Updates

TEC periodically updates its Interface Approval Standards to reflect changes in technology and network requirements. When a standard applicable to your certified product is updated, your certification may need to be re-evaluated against the new standard. Our team monitors TEC standard updates and proactively advises clients when their certification may be affected.

Penalties for Selling Telecom Equipment Without TEC Certification

Since the enforcement of the MTCTE policy, DoT and TEC have significantly strengthened compliance monitoring. The consequences of selling or importing non-certified telecom equipment in India are serious and have become increasingly difficult to avoid.

India's MTCTE enforcement has been particularly active since 2022. TEC and DoT have issued recall notices for multiple non-certified product categories and have directed customs to increase port-level checks. Acting proactively is the only safe approach for any serious telecom equipment business targeting the Indian market.

Real Example — How We Helped a European Networking Equipment Manufacturer Get TEC Certified

A European manufacturer of enterprise-grade IP phones and VoIP adapters approached Ornate Quality Services after their distributor in India received a show-cause notice from DoT. Several models of their IP phones had been identified as non-compliant under the MTCTE policy and were being sold in India without valid TEC Interface Approval.

The Challenge

The manufacturer had been selling their products in India through a local distributor for several years without TEC certification — largely because the MTCTE policy had been expanded to include their product category only recently. With a DoT notice already issued, they needed to get TEC certified quickly while also managing the existing compliance situation with their distributor.

What We Did

Our team conducted an immediate compliance assessment of their product portfolio — covering seven IP phone models and two VoIP adapter models. We identified the applicable TEC Interface Approval Standard for each product category, coordinated urgent testing at a TEC-empanelled lab in Delhi, and prepared the complete MTCTE portal applications in parallel with the testing process.

We also assisted the distributor in responding to the DoT show-cause notice by demonstrating that a TEC certification application was actively in progress — which helped defer enforcement action while the certification process was completed.

The Result

TEC Interface Approvals were obtained for all nine product models within four months. The DoT notice was satisfactorily resolved, and the distributor resumed normal sales operations. The manufacturer has since expanded their India-certified product range and now runs all new product launches through Ornate's compliance screening process before entering the Indian market.
