Nickel-Cadmium Battery BIS CRS Certification: Step-by-Step Registration Process

BIS CRS registration for nickel-cadmium batteries is mandatory for manufacturers, importers and brand owners who sell sealed secondary cells and batteries in India. The certificate proves the product meets Indian safety and performance norms and lets you legally sell the battery in the market.

Why this registration matters?

Batteries can be hazardous if they fail. The CRS makes sure batteries meet standards for safety and performance. It protects consumers and supports trustworthy brands. This also helps importers clear customs without delay. 

Products covered under CRS

The scheme covers sealed nickel-cadmium cells and batteries intended for portable applications, and related battery packs that fall under the notified Indian Standards. Check the BIS product list for exact scope before testing. 

Who must apply

Manufacturers in India must apply. Importers and authorised Indian representatives must also register models. Brand owners who market cells under a label must comply. If you sell in India, you must follow CRS rules.

Key documents to prepare

Gather these documents before you apply:

• Filled application form from BIS portal.
• Company incorporation or business registration proof.
• GST registration and PAN copy.
• NABL accredited lab test report for the model.
• Technical specification sheet and datasheet.
• User manual and label specimen.
• Authorisation letter for Indian representative, if applicable.
• Declaration of conformity signed by authorised signatory.

Testing and labs

BIS will also receive the reports supplied by the NABL accredited or BIS recognised labs. The tests are done in accordance with the Indian Standards that are in line with IEC standards. The electrical safety, charging and discharging behaviour, temperature performance, and leakage are tested. Make sure you use a lab that has experience in battery testing so that there is less rework.

Step by step process

1. Register on the BIS CRS portal and create an account.
2. Fill application model wise and upload documents.
3. Submit the NABL test report and pay the processing fee.
4. BEE reviews the file; BIS technically scrutinises reports.
5. BIS may inspect factory or sample units.
6. On approval, BIS issues a registration number and certificate.
7. Use the CRS mark and registration number on the product and packaging.

Fees and timelines

Fees include application charges, inclusion charges for test reports and annual registration fees. Labs charge separately for testing. The BIS fee structure shows processing and inclusion costs which vary by number of test reports. Typical time to grant is a few weeks to a few months depending on lab availability and inspections. Plan tests early to avoid launch delays.

Labeling and post registration duties

After registration you must label products with the CRS mark and unique number. Keep production and sales records. Report production figures to BIS as required. Any change in design or component that affects safety needs fresh tests and inclusion. Market surveillance checks may follow to verify compliance.

Common reasons for rejection

Applications fail when test reports come from non-accredited labs, when model numbers do not match, or when documents are incomplete. Mismatched sample and production units also cause refusal. Pre-check documents and use correct model identifiers to avoid delay

Practical tips for smooth approval

• Use a NABL lab experienced in battery tests
• Test the exact commercial model not a prototype
• Keep label and datasheet consistent across files.
• Respond fast to BIS queries.
• Maintain sample traceability with batch numbers.

Penalties for non-compliance

The promotion of unregistered batteries and mislabeled units may result in fines, confiscation of products and import restrictions. Traditions may hold unregistered deliveries. Recidivists are assigned heavier fines and may be delisted by the CRS.

Record keeping and audits

Store retention test reports, production records, invoices and label proofs. Retain documents over a number of years because BIS can audit or conduct market surveillance. Records are helpful in facilitating inspection and traceability

Recent updates in 2025

BIS refined CRS guidance and updated lab acceptance criteria in recent notices. Digital submission of lab reports and QR code linking for quick verification are becoming common. Check BIS CRS portal frequently for the latest circulars.

Checklist before submission

• Signed application and company proofs.
• NABL test report matching model.
• Label specimen and user manual.
• Payment receipt and authorised signatory proof.
• Photos of sample and packaging.

Technical standards to check

Confirm the exact Indian Standard your product must meet. For nickel-cadmium cells the standard aligns with safety norms. Check the IS number on the BIS CRS list. Ask the lab to give test results in BIS format

Sample management and traceability

Label each test sample with batch and heat numbers. Keep a sample register. Note who packed and who sent the sample. When inspectors arrive, show batch records. Traceability proves production and reduces disputes.

Importer responsibilities

If you import appoint an Indian authorised representative. Keep invoices and bills ready. Ask suppliers to share factory and material test certificates. Early planning avoids port holds. Customs can ask for CRS proof, so prepare ahead.

Final note

BIS CRS makes the market safer. Good labs, clear records and early planning cut delays. Use a checklist and track timelines to launch. BIS CRS can be complex for new applicants. Agile Regulatory prepares documents, coordinates NABL tests, files the application and follows up with BIS. They track deadlines and help manage factory inspections. With expert help you cut mistakes and get to market faster.
