Indutech's BIS Certification License assures that it meets the Bureau of Indian criteria' (BIS) quality and safety criteria. Manufacturers must adhere to applicable Indian Standards (IS) codes, such as IS 15891 (filter textiles) or IS 1891 (conveyor belts). The procedure consists of determining suitable standards, submitting an application through manakonline.in, product testing at a BIS-approved lab, and a factory inspection. Following compliance, BIS provides the license, authorizing the use of the ISI mark. To provide quality assurance, the accreditation must be renewed on a regular basis and subject to audits. This accreditation is critical to market acceptability and regulatory compliance.
