TEC, BIS and WPC serve different regulatory purposes. TEC's MTCTE framework addresses notified telecom equipment, BIS administers applicable product standards and certification schemes, and WPC handles relevant wireless and radio-frequency matters. A product may need one, two or several approvals, and one does not replace another. Check each framework independently against current official sources.
Are you planning to manufacture, import or sell electronic products, telecom equipment or wireless devices in India? Before launching your product, it is important to identify the applicable regulatory requirements. Depending on the product and its technical characteristics, you may need TEC certification, BIS certification, WPC approval or more than one of these approvals.
Although these terms are frequently used together in product compliance discussions, TEC, BIS and WPC serve different regulatory purposes. TEC's MTCTE framework addresses notified telecommunication equipment, BIS administers applicable product standards and certification schemes, and the Wireless Planning and Coordination (WPC) Wing handles relevant wireless and radio-frequency regulatory matters.
Choosing the wrong compliance route can lead to unnecessary testing, additional expenses and delays in bringing a product to market.
In this guide, Rego Services explains the differences between TEC, BIS and WPC approval in India, the products and regulatory requirements each may cover, and how manufacturers and importers can identify the appropriate compliance route.

1. What Is TEC Certification?
TEC certification is a commonly used term for approval and conformity assessment processes associated with the Telecommunication Engineering Centre under the Department of Telecommunications, Government of India.
For equipment covered by the Mandatory Testing and Certification of Telecommunication Equipment (MTCTE) framework, the applicable Essential Requirements must be satisfied and the required Certificate of Conformity Assessment obtained, subject to applicable rules and exemptions. MTCTE requirements may address technical parameters, electromagnetic compatibility, safety and other requirements specified for the equipment.
Which products may require TEC certification?
The official MTCTE product lists cover notified telecom and related equipment categories. Depending on the current notifications, examples may include certain:
- Routers and network switches.
- Optical network and transmission equipment.
- Cellular network equipment.
- Customer premises equipment.
- Other specifically notified telecom and ICT equipment.
These are illustrative examples. Not every router, networking product or electronic device automatically requires the same MTCTE certification.
How to check TEC applicability
- Identify the exact product and model.
- Check the current MTCTE phase-wise product list.
- Identify the applicable Essential Requirements.
- Verify the certification scheme and any additional requirements.
- Check relevant notifications, exemptions and mandatory dates.
Official reference: MTCTE Portal. For the detailed application workflow, read our TEC Certification Process Guide.
2. What Is BIS Certification?
The Bureau of Indian Standards (BIS) is India's national standards body. It administers certification and conformity assessment schemes for products covered by the applicable requirements.
BIS certification is not a single universal scheme for all products. The applicable route depends on the product category, relevant Indian Standard and governing order or certification scheme. For example, certain electronics and information technology goods are covered by the Compulsory Registration Scheme (CRS). Other product categories may be governed by different BIS certification arrangements, including applicable licence-based schemes and Quality Control Orders.
Which products may require BIS certification?
The applicable BIS requirements depend on the relevant product order or scheme. Examples of products covered by particular BIS schemes may include:
- Specified electronic and IT products.
- Certain electrical appliances.
- Products covered by applicable Quality Control Orders.
- Other products included in mandatory BIS certification or registration requirements.
The product name alone is not sufficient to establish applicability. Confirm the relevant Indian Standard, product category, effective date and scheme.
How to check BIS applicability
- Identify the product and intended use.
- Check the applicable BIS product category and Indian Standard.
- Review the current compulsory certification order or registration scheme.
- Verify the implementation date and any applicable exemptions.
- Follow the prescribed BIS application and testing procedure.
Official reference: BIS Scheme II Registration Scheme.
3. What Is WPC Approval?
The Wireless Planning and Coordination Wing operates under the Department of Telecommunications and handles relevant wireless and radio-frequency regulatory matters.
One commonly discussed approval is Equipment Type Approval (ETA). Under the applicable route, ETA may be required for specified wireless devices operating in de-licensed frequency bands permitted in India. The DoT describes an ETA self-declaration route for eligible commercial or finished products, including certain mobile and computing devices, short-range devices, microphones, speakers, headphones and cameras operating in permitted bands.
This does not mean every product in those categories automatically requires the same approval. The applicable route depends on its wireless characteristics, intended operation and current requirements.
Which products may require WPC ETA?
Depending on the equipment and applicable rules, wireless compliance assessment may be relevant to products such as:
- Bluetooth-enabled devices.
- Wi-Fi-enabled products.
- Wireless headphones and speakers.
- Certain short-range wireless devices.
- Other equipment operating in applicable de-licensed frequency bands.
Other wireless equipment may be subject to different authorisation or licensing requirements. Do not assume that ETA is the correct route for every radio transmitter or receiver.
How to check WPC applicability
- Identify the product's radio interfaces and supported frequency bands.
- Confirm whether the equipment operates in a permitted de-licensed band.
- Check the applicable WPC/DoT approval route.
- Review the required RF test reports and technical documentation.
- Confirm whether the self-declaration route is available for the specific product.
Official reference: DoT Equipment Type Approval (ETA).
4. Do You Need TEC, BIS and WPC Approval for the Same Product?
Not necessarily. A product may be subject to one, two or several regulatory requirements, depending on its classification and technical features. The correct compliance route cannot be determined simply by checking whether a product contains electronics, connects to a network or uses wireless communication.
A router may need to be assessed against the applicable MTCTE product category. If the device also uses wireless interfaces, additional wireless requirements may need to be examined. BIS applicability should be checked separately against the relevant product orders and standards rather than assumed.
A Bluetooth speaker may require assessment under the applicable WPC ETA route if it falls within the relevant wireless requirements. Whether BIS certification is required depends on the applicable product scheme or order. TEC applicability must be independently checked against the notified MTCTE product categories.
A laptop may be covered by applicable BIS requirements under the relevant electronics certification scheme. Its wireless interfaces may also require a separate assessment under applicable WPC rules. TEC applicability should be determined independently and not assumed solely because the laptop contains wireless connectivity.
Equipment intended for telecom networks may fall within the MTCTE framework. Additional BIS or wireless requirements may also apply if the product falls within their respective regulatory scope.
These examples illustrate how to assess the frameworks; they are not definitive product-specific legal determinations. Always check the latest official requirements for the exact model.
5. TEC vs BIS vs WPC: How to Choose the Correct Approval
Use this decision process as an initial screening tool.
Step 1: Does the product fall under a notified MTCTE category?
Check the official MTCTE product list and applicable Essential Requirements. If the equipment is covered, determine the required conformity assessment route and any applicable exemptions.
Step 2: Is the product covered by a BIS certification or registration requirement?
Check the relevant BIS scheme, Indian Standard, Quality Control Order or compulsory registration order. Do not assume that TEC certification replaces an applicable BIS requirement.
Step 3: Does the product use wireless or radio-frequency functionality?
Identify its radio interfaces and operating bands, then check the relevant WPC/DoT rules. Where applicable, determine whether ETA self-declaration or another authorisation route is required.
Step 4: Check whether multiple requirements apply
A product may fall under more than one framework. Confirm the applicable obligations independently rather than treating the approvals as interchangeable.
Step 5: Confirm current requirements before applying
Product classifications, notifications, exemptions and procedures may change. Use current official sources before planning tests or submitting an application.
6. What Documents Are Required for TEC, BIS and WPC Approval?
The documentation varies by framework and product.
Documents commonly relevant to TEC / MTCTE

The current official requirements should be checked for the specific product and route.
7. What Are the Differences in Cost and Processing Time?
TEC, BIS and WPC do not have one common fee or approval timeline. The total cost and duration depend on the applicable procedure, test scope, laboratory arrangements, documentation, application complexity and any additional regulatory conditions.
| Factor | TEC / MTCTE | BIS | WPC |
|---|---|---|---|
| Fees | Applicable certification fees and testing charges | Fees prescribed by the relevant BIS scheme and testing arrangements | Applicable ETA or other approval charges |
| Testing | Based on relevant Essential Requirements | Based on the applicable Indian Standard and scheme | RF testing or other evidence as required by the route |
| Timeline | Depends on testing and MTCTE assessment | Depends on the scheme, testing and assessment | Depends on the applicable approval route and documentation |
| Key verification | Current MTCTE procedure and notifications | Current BIS scheme and product orders | Current DoT/WPC requirements |
Do not rely on a single generic fee or timeline when preparing a product launch plan. Obtain a product-specific estimate after confirming the applicable regulatory route. For TEC-specific cost considerations, read our TEC Certification Fees Guide.
