The Bureau of Indian Standards (BIS) operates two compulsory registration schemes that affect a wide range of imports: the ISI mark scheme for products governed by quality-control orders, and the Compulsory Registration Scheme (CRS) for electronics and IT goods. If an imported product falls under a mandatory BIS standard and the importer cannot show a valid registration or licence, customs can detain the shipment, refuse clearance and even order re-export. This guide explains which products are covered, the difference between ISI and CRS, how to obtain registration, and the documentation that keeps cargo moving.
What BIS compliance actually covers
BIS is India's national standards body. Through Quality Control Orders (QCOs) issued by various ministries, BIS makes Indian standards compulsory for specified products. Compliance is shown either by an ISI mark licence (for products under the BIS certification scheme) or by registration under the Compulsory Registration Scheme (for electronics and IT goods). The obligation applies whether the goods are manufactured in India or imported.
ISI mark scheme vs CRS
| Feature | ISI Mark Scheme | Compulsory Registration Scheme (CRS) |
|---|---|---|
| Products | Cement, steel, tyres, batteries, food products, household appliances, chemicals and many others | Electronics, IT goods, LED lights, mobile phones, laptops, power banks and similar |
| Marking | ISI mark with licence number CM/L on product and packaging | Standard mark with R-number on product and packaging |
| Factory inspection | BIS inspects the manufacturing unit | No routine factory inspection; product tested in BIS-recognised lab |
| Application route | Through BIS portal; includes sample testing and factory audit | Through BIS portal; self-certification based on test reports from recognised labs |
| Validity | Typically one year, renewable | Typically two years, renewable |
Products commonly under BIS mandatory standards
- Cement, steel and structural products — IS 1489, IS 2062 and related standards.
- Electrical cables, switches, capacitors and domestic electrical appliances.
- Food products including packaged drinking water, milk powder and infant food.
- Tyres, tubes, automotive components and helmets.
- Chemicals, fertilizers and certain industrial inputs.
- Electronics and IT goods under CRS, such as mobile phones, tablets, printers, LED lamps and power adapters.
The CRS registration process
- 1Identify the applicable Indian standard (IS number) and the QCO that made it mandatory.
- 2Get the product tested in a BIS-recognised laboratory, either in India or abroad if the lab has a mutual recognition arrangement.
- 3Create an application on the BIS portal and upload the test report, factory documents and authorised Indian representative details.
- 4BIS reviews the application and, if complete, grants registration and a unique R-number.
- 5Apply the standard mark with the R-number on the product and packaging before import.
- 6Renew before expiry; any design or component change may require fresh testing.
Labelling and documentation at import
Every BIS-regulated product must carry the applicable mark (ISI or CRS standard mark) and the licence or registration number on the product itself and on the retail packaging. The bill of entry should declare the BIS registration or licence number, and the importer should keep the registration certificate and test reports ready for customs examination. Missing or incorrect marking is the most common reason for detention.
How to avoid customs holds
- Check the latest QCO list before ordering — new products are added regularly.
- Confirm that the supplier has applied the correct mark and R-number or CM/L number.
- Ensure the product description and HS code on the invoice match the BIS registration.
- Keep registration certificates and lab test reports available during customs examination.
- For products not yet under a QCO, obtain a no-compulsion certificate or legal opinion if there is any doubt.
BIS rules evolve quickly. A product that did not need registration last quarter may be covered by a fresh QCO today. We verify the current mandatory list before every shipment and can guide importers through the registration or clearance process.
Frequently asked questions
What happens if I import a BIS-regulated product without registration?
Customs can detain the goods, refuse clearance and may order re-export or destruction. The importer may also face penalties under the BIS Act and the relevant QCO.
Can a foreign manufacturer apply for BIS registration directly?
Yes, but foreign manufacturers usually appoint an authorised Indian representative (AIR) to handle the application, testing coordination and compliance on the ground.
Does BIS registration replace an import licence?
No. BIS registration is a quality-compliance requirement. If the product also needs an import licence, FSSAI clearance, WPC approval or any other permit, those remain separate obligations.
How do I know if my product needs ISI or CRS?
Check the latest Quality Control Orders on the BIS website or consult a compliance specialist. As a rule, electronics and IT goods fall under CRS, while industrial, chemical and consumer products usually fall under the ISI mark scheme.
