A Bureau of Indian Standards (BIS) license is a certification required by manufacturers to verify that their products meet Indian quality and safety standards. It is required for some products, including electronics, food, and industrial goods. The process entails determining the suitable Indian Standard (IS) Code, applying through the BIS site, submitting the required documentation, and having the product tested in a BIS-approved lab. BIS personnel conduct factory inspections to ensure compliance. If authorized, the manufacturer is issued a BIS license, which allows them to use the ISI mark on their product. The certification must be renewed on a regular basis, and compliance audits may be done. The process entails application fees, testing fees, and an annual license price. Obtaining a BIS license enables firms to ensure product quality, create consumer trust, and meet regulatory criteria. It is crucial for producers who intend to market regulated items in India.
