The Bureau of Indian Standards (BIS) license ensures that a product fulfills Indian quality and safety standards. It is required for a variety of items, including electrical appliances, electronics, and building materials. To receive a BIS license, applicants must first register on the BIS website, then submit the necessary documentation, test their products in BIS-approved labs, and undergo factory inspections. Once accepted, the product may bear the ISI mark or CRS certification. The license is valid for one or two years and must be renewed on a regular basis. BIS certification guarantees product reliability, customer safety, and regulatory compliance in the Indian market.
