India's Bureau of Indian Standards runs two distinct conformity schemes: CRS for electronics and IT goods, and ISI Mark for industrial and household products. Choosing the wrong one wastes months and thousands of rupees in application fees.

BIS CRS is a self-registration scheme for electronics and information technology goods. Introduced under the BIS Act 2016 Section 10(1), it applies to products notified by the Ministry of Electronics and Information Technology (MeitY) and other ministries as compulsorily registrable. CRS does not require a factory audit. The manufacturer submits test reports from BIS-recognized labs, self-declares conformity, and receives a registration number. The Standard Mark with the R-Number must then appear on the product and packaging. The scheme is designed for fast-moving consumer electronics where factory audits would create unacceptable delays. Most CRS registrations complete in 15-30 days after test report submission. ## What is BIS ISI Mark? BIS ISI Mark is the traditional certification scheme under the BIS Act 2016 Section 14. It applies to industrial products, household appliances, chemicals, and building materials where quality consistency and manufacturing process control are critical. ISI Mark certification requires a detailed factory audit by BIS inspectors. The audit examines manufacturing processes, quality control systems, testing facilities, and raw material traceability. This is why ISI Mark certification takes 90-120 days and requires ongoing surveillance audits. The ISI Mark itself carries the license number (CM/L-xxxxx) and signifies that the product meets the relevant Indian Standard (IS) specification and that the manufacturing facility maintains adequate quality systems. ## Products typically under BIS CRS Electronic watches LED luminaires and LED lights CCTV cameras and recorders Cash registers and POS terminals Smart card readers and biometric devices Mobile phones, tablets, and laptops Power adapters and chargers IT equipment including printers and scanners This is a representative list. The full compulsorily registrable goods list is published by MeitY and updated periodically. Always verify current applicability before applying. ## Products typically under BIS ISI Mark Steel products and cement Electrical cables and wires Transformers and capacitors Pressure cookers and domestic gas stoves Water meters and electricity meters Medical equipment like X-ray machines Household appliances like mixers and irons Industrial chemicals and fertilizers ISI Mark covers over 300 product categories. The BIS certification scheme operates on a product-by-product basis with specific Indian Standards for each category. ## Key differences at a glance AspectBIS CRSBIS ISI Mark Registration vs CertificationCRS is a registration scheme — no factory audit requiredISI is a certification scheme — mandatory factory audit Governing ActBIS Act 2016, Section 10(1)BIS Act 2016, Section 14 Mark AppliedStandard Mark with R-NumberISI Mark with license number Application RouteOnline through BIS portal, self-attested documentsDetailed application with factory inspection Timeline15-30 days after test report submission90-120 days including factory audit Validity2 years, renewable1-2 years, subject to surveillance audits ## Frequently asked questions ### Can a product require both BIS CRS and ISI Mark? Generally no — a product falls under one scheme based on its category. However, if your product contains sub-components that fall under different categories, each component may need its own compliance. For example, a laptop needs CRS registration as a whole, but its power adapter may also need separate CRS registration if sold standalone. ### What happens if I apply for the wrong certification? If you apply for ISI Mark when CRS applies, BIS will reject your application after initial review. If you apply for CRS when ISI Mark is required, you may get registration but face enforcement action later. Use our decision tool to verify before applying — it checks your product category against the official BIS compulsorily registrable goods list. ### Do foreign manufacturers need a different approach? Foreign manufacturers can apply for both CRS and ISI Mark, but must appoint an Authorized Indian Representative (AIR) with a permanent address in India. For CRS, the AIR handles the registration. For ISI, the AIR coordinates factory audits if the manufacturing facility is overseas — though ISI Mark is rarely sought by foreign manufacturers due to the factory audit requirement. ### Is the testing laboratory the same for both schemes? No. CRS requires testing at BIS-recognized labs (often foreign labs with ILAC accreditation are accepted). ISI Mark requires testing at BIS-approved labs in India specifically. For CRS, you can use test reports from accredited labs abroad. For ISI Mark, samples are typically tested in India even for foreign manufacturers. **Disclaimer:** This guide is based on the BIS Act 2016 and official notifications from MeitY and BIS. Product categorization can change with new government orders. Always verify current applicability with the official BIS compulsorily registrable goods list before applying.
