Introduction
Tamil Nadu is highly industrialized and has a good automobile, textile, electronics, and leather industry presence in India. BIS ISI certification is in high demand in those cities where the concentration of industrial activities is the highest, such as Chennai, Coimbatore, Tiruppur, Hosur, and Madurai. In this case, ISI certification is not only a legal obligation of businesses but also a tactical step to acquire legal approval to sell in the market. Large-scale automobile manufacturers based in Chennai, as well as textile exporters who base their operations in Tiruppur, rely on ISI certification to ensure that their products meet the national standards. Brand Liaison acts as a trusted partner for companies in the state by simplifying the process of application, documentation, testing, and approval, enabling businesses to expand confidently in domestic and international markets.
What is BIS ISI Certification?
BIS ISI Certification is a quality and safety mark certification for the notified products covered under the Applicable product list before being sold in India. It shows that a product is up to the standards of India, and it can be used in the domestic market.
BIS ISI certification is issued by the Bureau of Indian Standards (BIS), the national standards body of India. It ensures that the products sold in Tamil Nadu are of high quality, safe, and reliable.
Who Should Apply for an ISI Mark Certification?
All Manufacturers (Indian and Foreign) who are selling or exporting certain notified products into India must apply for a BIS ISI Certification. It is important to comply with Indian laws to gain smooth market access.
Importers and traders cannot apply directly for a BIS ISI license, as the BIS license is granted only to the actual manufacturer. Importers are advised to request a copy of the BIS ISI certificate from the actual manufacturers to sell the products in India.
