TAC APPROVAL FOR AUTOMOBILE: The Certification that production samples of a design will get after achieving specified performance standards is known as vehicle type approval. With the implementation of the India Central Motor Vehicles Rules in 1989, AIS certification became available (CMVR). The CMVR publishes rules and regulations relating to vehicle approval, traffic restrictions, and the production and maintenance of motor vehicles, among other things. The Ministry of Road Transport and Highways is the responsible body for enforcing emission legislation, including Type Approval and production Conformity. The MORTH has established a standing Committee on Emission Legislation implementation, chaired by joint Secretary of MORTH, to advise the nodal agency on such implementation. TACs are awarded for products that must meet stringent technical and safety standards.

If the number of base models and variants manufactured/imported is more than one, and the individual base model and variants are less than 250 in any six-month period in a year, the testing agencies may select one vehicle from among such models and variants once a year to conduct such tests.


TAC stands for Type Approval Certificate is a certificate of conformity given to automotive products.TAC Approval or Type Approval Certification is given to a product that meets regulatory compliance, technical, and safety requirements.

Homologation Certification is the process of certifying automobiles for roadworthiness according to the government's criteria for all vehicles manufactured or imported into the country. The tests guarantee that the vehicle satisfies the criteria in terms of safety and performance.


The Government of India has designated ARAI as one of the primary testing and certification agencies under Rule 126 of the Central Motor Vehicle Rules, 1989. The Automobile Research Association of India (ARAI), founded in 1966 by the automotive industry in collaboration with the Indian government, is the country's largest automotive R&D organization.

The Automotive Research Association of India (ARAI) provides comprehensive certification and homologation services for a wide range of automotive vehicles, systems, and components. ARAI also provides assistance to car manufacturers in the area of export homologation. The international certification bodies of Singapore, the Netherlands, and Australia have recognized ARAI for conducting testing in accordance with their standards.

The Automobile Industry Standard, or AIS, is a technical automotive standard for India. The Central Motor Vehicle Act of 1989 mandated AIS Certification.


Automotive Electronics, Gasoline Tanks, Safety Glass, Tires, Seat Belts, Brake Hoses, Lights, Batteries, and Door Locks are examples of products that fall under this category.


  1. A producer of such product or a participant in the production process
  2. Importers or Dealers who purchase a product from a foreign producer
  3. A foreign manufacturer has its business in India and is involved in trading activities


  1. Application form in the prescribed format
  2. Compliance report and test results in accordance with the method prescribed.
  3. In the case of Traders, Authorization letters from the manufacturer appoint him as the product's trader.
  4. A sample of the product for testing,
  5. A technical document including Installation instructions, operating manuals, and maintenance manuals.


Type Approval Certification process consists of the following steps.

  1. Submit application - Collect all the above-mentioned documents and applications from the manufacturer. Review all documents carefully, and after reviewing, submit an application with the required documents.
  2. Product testing In India - After collecting and verifying all the documents, in the next step, product testing is done in India from a recognized testing center.
  3. Factory audit - Auditors from India conduct factory premises inspections to check whether everything is according to the provided information in the application.
  4. Issue of Certificate - If the auditors get a satisfactory report of the product and manufacturing premises, the certificate will be issued.
  5. Marking and labeling of the parts - At last, marking and labeling of the parts is done.

Note: Electromagnetic compatibility tests of automobile electronics can be carried out at the manufacturer's facilities under specified conditions and do not need to be carried out separately in India.


The average processing time taken for a grant of TAC is approximately 1 months for Indian manufacturers and 2 months for the foreign manufacturer. The rest will depend upon the circumstances. It may vary due to certain factors like applicant delays in response to queries raised, if any, delay in conducting inspection or testing of the sample, delay in repayment of dues, etc.
