Quick Answer – BIS ISI Certification and BIS CRS Registration are two different product certification schemes introduced by the Bureau of Indian Standards (BIS). ISI Mark Certification comes under Scheme-I and generally involves product testing, factory inspection, and quality control assessment. Whereas BIS CRS Registration comes under Scheme-II and mainly covers notified electronic and IT products, requiring product testing in a BIS-recognised laboratory and document verification. Both schemes ensure that products meet the applicable Indian Standards before being sold in India. Brand Liaison provides consultancy for both the BIS certification schemes for the Indian market, including faster approvals, document preparation, eligibility checks, and more.

Introduction

In India, the Bureau of Indian Standards (BIS) plays an important role in maintaining the quality and safety of products being sold in the market. It introduces different types of BIS Certification schemes to ensure that notified products meet the applicable Indian Standards.

Among BIS's various schemes, ISI Mark Certification and BIS CRS Registration are two commonly required product compliance certifications. However, businesses often get confused about which certification applies to their products.

Understanding the difference between the two certifications is important for manufacturers who import or sell the notified products in India. In this blog, we explain both schemes, their requirements, and their major differences.

What is BIS ISI Certification?

BIS ISI Certification is a mandatory product certification scheme for various products listed under the BIS ISI applicable product checklist. It allows manufacturers to use the ISI Mark on the notified products that meet the requirements of the relevant Indian Standard.

Manufacturers must obtain the required BIS ISI license before selling or importing the notified products in the Indian market.

It mainly covers products related to consumer safety, construction, electrical equipment, and industrial applications.

Products Covered Under ISI Certification

Here are the notified products covered under the ISI Certification Scheme:

  • Cement and steel products
  • Plywood
  • Electrical cables and wires
  • Pressure cookers
  • LPG cylinders
  • Packaged drinking water
  • Helmets
  • Footwear
  • Household electrical appliances

Moreover, manufacturers should first check the products' eligibility for BIS ISI certification. This results in fewer delays and faster certification approvals. 

Features of BIS ISI Certification

  • Factory Assessment: To obtain BIS Certification, the officials inspect the manufacturing unit of the manufacturers to check production facilities, machinery, and quality control arrangements.
  • Testing Products at BIS-accredited labs: Some samples of the products are tested at labs recognized by BIS to verify compliance with the applicable Indian Standard.
  • Maintain Quality Control: Businesses must maintain proper quality control and testing facilities.
  • ISI Mark: The certified products must carry the ISI Mark along with the relevant IS number and CM/L license number.

What is BIS CRS Registration?

BIS CRS (Compulsory Registration Scheme) is a mandatory certification registration for the notified electronic and IT products covered in the applicable CRS product list for import or sale in India.

Under this registration, eligible manufacturers must get their notified products tested in a BIS-recognised laboratory and register them with BIS before selling them in India. It generally follows a product-testing and registration-based process without a factory inspection before registration.

Products Covered Under CRS Registration

The following are the common electronic products covered under the CRS scheme:

  • Mobile phones
  • Laptops and tablets
  • LED lights
  • Power banks
  • CCTV cameras
  • Smart watches
  • Bluetooth speakers
  • LED televisions
  • UPS and inverters
  • Power adapters

Note: Manufacturers must verify the eligibility of the notified electronic and IT products for CRS registration before obtaining registration.

Features of BIS CRS Registration

  • Testing at BIS-recognised labs: The notified product samples are tested in a BIS-recognised laboratory as per the applicable Indian Standard.
  • No Factory Inspection: There is no requirement for factory inspection for CRS registration.
  • R-Number: The notified electronic products must carry the applicable Mark and registration number.
  • Market Surveillance: BIS officials may conduct market surveillance and test products to check continued compliance.

Selling the notified or covered products without the required ISI certification or CRS registration creates legal compliance issues for manufacturers, importers, and other eligible sellers.

The following are the risks related to non-compliance:

  • Restrictions on importing or selling the product.
  • Seizure of non-compliant products.
  • Imprisonment and other legal action.
  • No customs clearance for imports.
  • Suspension or cancellation of an existing BIS license or registration, where applicable.
  • Business financial loss

Therefore, manufacturers and importers must identify the correct BIS certification scheme and complete the required certification before importing or selling the notified products in the Indian market.

Other Certifications Required for Notified BIS Products

The Bureau of Indian Standards has provided an applicable product checklist that needs mandatory BIS Certification Compliance. 

However, the notified products under BIS product list can require other mandatory certifications like electrical appliances under CRS can require compliance with BEE Certification as well. Similarly, TEC, WPC, and EPR certifications must also be obtained for the products falling under multi-certification requirement. 

You can connect with Brand Liaison, a reputed product compliance consultancy firm to get these certifications smoothly and sell the products confidently in the Indian market. 

Note: If an electrical product is eligible for BIS ISI Certification, then it cannot obtain BIS CRS Registration. Only one of the certifications is mandatory to obtain in India.

Conclusion

Both BIS ISI Certification and BIS CRS Registration are two different BIS schemes introduced to ensure that notified products meet the applicable Indian Standards.

While ISI Mark registration mainly covers products that require manufacturing facility assessment, CRS Registration primarily covers notified electronic and IT products through product testing and registration.

Manufacturers and importers can connect with Brand Liaison, a trusted BIS Consultant in India, to check the applicable BIS notification and Indian Standard before starting the certification process.
