How To Know ISI Mark On Helmets Is Genuine


  • Genuine helmets have the "ISI mark", the helmet's IS code (IS 4151)  above the ISI mark and manufacturer's code (CM/L)  below the ISI mark
  • The ISI mark is not a removable sticker, it is non removable laminated print.
  • Costumers can verify the manufacturer at BIS website http://www.bis.org.in by providing the CM/L code in the "Product Certification - Online information - Application/License related" field.
  • Each helmet shall be clearly and indelibly marked with the manufacturer's name or trademark, size, year of manufacture and mass of the helmet.
