CRS BIS Registration is a compulsory approval required for certain electronic and IT products before they can be sold or imported into India. CRS stands for Compulsory Registration Scheme, and it is managed by the Bureau of Indian Standards (BIS). In simple words, this system makes sure that electronic products used by people in India are safe and meet basic quality standards.Under CRS, products are tested in BIS-approved laboratories. If the product passes testing, the manufacturer declares that it meets Indian standards and is allowed to use the BIS Standard Mark. Without this registration, products can be stopped at customs, removed from online platforms, or even banned from sale. This rule applies to both Indian and foreign manufacturers.
