The BIS Certification License for potable water bottles in India guarantees adherence with Indian Standards (IS) for safety and quality. The pertinent criteria call for IS 14723 for stainless steel bottles and IS 15410 for polycarbonate bottles. Manufacturers have to apply using the Manak Online Portal, send required paperwork, go through a factory inspection, and pass product testing in a BIS-registered laboratory. Approved, they get an ISI Mark License—mandatory for market compliance. The certification calls for regular renewing and compliance audits. In the Indian market, BIS certification guarantees customer safety and regulatory compliance, therefore improving the product reputation.
