Common Confusion Between CRS, ISI Mark, and Hallmarking
These three distinct BIS-related certification schemes are sometimes conflated, and clarifying the differences helps businesses pursue the correct one.
These three distinct BIS-related certification schemes are sometimes conflated, and clarifying the differences helps businesses pursue the correct one.
CRS (Compulsory Registration Scheme) applies specifically to electronics and IT products, involving product testing and registration rather than the traditional ISI mark process.
The ISI mark represents BIS's more traditional certification scheme, applicable to a broad range of non-electronics product categories under mandatory or voluntary certification.
Hallmarking is a distinct scheme specifically for precious metals (particularly gold), certifying purity rather than the broader safety/quality parameters that ISI mark or CRS certification address.
Confirming which specific scheme applies to your product — rather than assuming based on general 'BIS certification' terminology — ensures you pursue the correct, applicable process.
Frequently Asked Questions
Are these three schemes interchangeable?
No, each applies to distinct product categories with its own specific process — confirming which applies to your specific product is essential.
Does a single product ever require more than one of these schemes?
This would be unusual given how distinctly these schemes are scoped to different product types, though confirming your specific product's exact requirements is always worthwhile.
