# BIS · BIS Compulsory Registration Scheme (CRS)

India's market-access scheme for products in the compulsory registration scope. Testing must be completed at a BIS-recognised Indian laboratory — overseas reports are generally not accepted. Once registered, the standard mark and registration number (R-number) may be applied.

| | |
|---|---|
| Issued by | Bureau of Indian Standards (BIS) |
| Assessment route | Compulsory registration |
| How it is obtained | Confirm whether the product is in scope and which IS edition applies; test at a BIS-recognised laboratory; submit factory details and proof of the manufacturing address; appoint an Authorised Indian Representative (AIR). |
| Marking rules | The standard mark must appear together with the registration number, in the format and position specified by BIS. Unregistered models may not use it. |
| Validity and upkeep | Registration is typically valid for two years and renewable; scope and standard revisions trigger review. |
