What is a BIS Certificate of Conformity (CoC)?

BIS Certificate of Conformity
Batch & Product Type Conformity Assurance BIS Scheme-IV / Scheme-X

The Certificate of Conformity (CoC) is granted by the Bureau of Indian Standards (BIS) under Scheme-IV (and Scheme-X for specific critical machinery) of the BIS (Conformity Assessment) Regulations. Unlike standard ISI mark licensing which requires a permanent in-house lab and continuous surveillance, CoC is often issued for specific product lots, customized assemblies, or products where type testing and factory conformity evaluation suffice.

CoC is essential for specialized electrical equipment, transformers, industrial machinery, and components imported or supplied for critical infrastructure, government tenders, and defense sectors in India.

Lot & Batch Compliance

Permits compliance verification for specific consignments or batches without long-term factory surveillance obligations.

Statutory Customs Release

Enables swift customs clearance for imported capital goods, project equipment, and specialized precision instruments.

CoC Applicability

Common Products Covered under BIS CoC

Products and sectors frequently seeking BIS Certificate of Conformity:

Transformers & Power Gear
Distribution & Power transformers, substations, switchgears
Industrial Machinery
Pumps, compressors, diesel engines, lifting equipment
Renewable Energy Components

Procedure

Process to Obtain BIS CoC

1
Technical Scrutiny & Standard Mapping

Mapping product technical specifications to relevant Indian Standards (IS/ISO/IEC equivalent) and identifying required test parameters.

2
NABL Lab Testing Coordination

Submitting product samples to BIS-recognized or NABL accredited laboratories for complete type testing.

3
Dossier Submission on Manakonline

Filing application on the BIS portal with test reports, technical construction file, quality system documents, and declaration of conformity.

Scrutiny & Grant of Certificate of Conformity

BIS scrutinizes test results and documentation, issuing the official Certificate of Conformity for regulatory and customs use.

CoC FAQs

Frequently Asked Questions

An ISI Mark License (Scheme-I) requires full in-house lab setup and factory surveillance for continuous serial manufacturing. A Certificate of Conformity (Scheme-IV) evaluates conformity based on type test reports and quality checks, suitable for specific lots or equipment types.

The CoC is typically valid for 1 to 3 years or for the specified consignment/lot, after which renewal or fresh batch certification is required.
