BIS certification is mandatory for DC supplied and battery operated air purifiers in India. The requirement comes from the Safety of Household, Commercial and Similar Electrical Appliances (Quality Control) Order, 2026 (S.O. 1739(E), dated 6 April 2026). The Order comes into force on 1 October 2026 for large and medium enterprises, 1 January 2027 for small enterprises, and 1 April 2027 for micro enterprises. These air purifiers must conform to IS 302 (Part 1):2024, which is harmonised with IEC 60335-1, together with any applicable particular requirements. Each unit must carry the ISI Mark under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018. Products manufactured in India solely for export are exempt. Foreign manufacturers apply through the Foreign Manufacturers Certification Scheme (FMCS). Non-compliance is punishable under the BIS Act, 2016.
A DC supplied or battery operated air purifier is a compact appliance that draws in room or cabin air and passes it through a filter or other cleaning stage. It runs from a built-in rechargeable battery, a USB or adaptor supply, or a 12 V vehicle socket. Typical examples are car air purifiers, desktop and personal purifiers, and portable units for small rooms. Because these products combine a fan, a battery or charging circuit and sometimes an ionizer or UV-C stage, they carry shock, heat, fire and radiation risks that mains-only products do not.
The 2026 Quality Control Order for household and similar electrical appliances makes BIS certification compulsory for this product group. Manufacturers need a BIS licence and the ISI Mark. Importers and brand owners must source only from BIS-licensed factories. This guide explains what the Order requires, which standard applies, what testing involves and how to plan your certification.

Is BIS Certification Mandatory for Battery Operated Air Purifiers?
What Is BIS Certification for DC Supplied Air Purifiers?
BIS certification is the licence and ISI Mark that the Bureau of Indian Standards grants once an air purifier model has been tested and found to conform to IS 302 (Part 1):2024 and the applicable particular requirements. It is how the 2026 Quality Control Order is enforced for this product.
Yes. The Ministry of Commerce and Industry notified the Order on 6 April 2026. It supersedes the 2025 Order and covers 90 appliance categories, including air-cleaning appliances. The scope of IS 302 (Part 1) reaches appliances rated up to 250 V single-phase, and up to 480 V for other supplies, including DC and battery-operated ones. Once the Order applies to you, such an air purifier cannot lawfully be manufactured, imported, distributed or sold unless it conforms to the notified standard and bears the ISI Mark. You can read the Order's scope on the Department for Promotion of Industry and Internal Trade website. Licence and standards information is published by the Bureau of Indian Standards.

Applicable Standard: IS 302 (Part 1):2024
India's household electrical safety standard is the IS 302 series. A general part applies to every household appliance. A particular part, where one applies, adds requirements written for a specific appliance group — for air purifiers, the international reference is IEC 60335-2-65.
Products Typically Assessed Under This Category
12 V or USB-powered units fitted in cup holders, headrests or dashboards.
Units with a built-in battery for small rooms, desks, nurseries and travel.
Compact purifiers supplied through a USB cable, power bank or external DC adaptor.
Models adding an ionizer, electrostatic stage or UV-C lamp, which need extra checks.
QCO 2026 Implementation Dates
The Order applies different start dates by enterprise size, as defined under the Micro, Small and Medium Enterprises Development Act, 2006.
The Order applies to both domestic manufacturers and importers. Goods manufactured in India purely for export are outside its scope.
Mandatory Tests for DC Supplied Air Purifiers
Samples are tested at a BIS-recognised laboratory against IS 302 (Part 1):2024 and any applicable particular requirements. The exact test plan depends on the edition in force and your model's construction. Testing generally falls into these groups:
Depending on the design, additional checks may apply, such as moisture resistance, creepage and clearance distances, and component endurance. Marking durability and the instruction manual are reviewed alongside these tests.
Marking and User Information
- ISI Mark — the Standard Mark with the BIS licence number (CM/L number), on the product, rating label, packaging and manual.
- Rating label — rated DC voltage, input power or current, battery details where applicable, model or type, and manufacturer name, address and brand.
- Safety instructions — charging guidance, filter replacement and cleaning, and warnings for ionizer or UV-C stages.
- Special parts — compatibility notes for the specified adaptor, cable or vehicle socket.
BIS Certification Process — Step by Step
The process below follows Scheme-I. Delays usually come from incomplete documents or samples that fail in the laboratory.
Confirm that your product is an air-cleaning appliance under the Order, identify the standards that apply, and check which implementation date applies to your enterprise.
Group models by rating, construction and features such as ionizer or UV-C. Freeze the motor, cell, charging circuit and adaptor details before testing begins.
Compile factory, quality-control, product and authorisation documents. Foreign manufacturers also appoint an Authorised Indian Representative.
Submit the Scheme-I application with fees and supporting documents on the BIS online portal. BIS scrutinises the file and may raise queries.
A BIS officer inspects the manufacturing process, in-house testing facilities and quality system, and draws samples from your production.
Samples are tested against IS 302 (Part 1):2024 and any particular requirements. A failed test means corrective action and retesting, so pre-compliance checks save time.
BIS reviews the inspection findings and test reports. When every requirement is met, the licence is granted with a CM/L number for the certified models.
Mark every certified unit with the ISI Mark and licence number, then comply with periodic surveillance, marking fees and renewal.
Indian Manufacturers vs Foreign Manufacturers (FMCS)
The standard and the tests are the same for everyone. What differs is how the licence is applied for, how the factory is inspected, and who holds accountability in India.
| Business | Typical BIS Responsibility |
|---|---|
| Indian manufacturer | Apply for the Scheme-I BIS licence covering each certified model |
| Foreign manufacturer | Apply through the FMCS route and appoint an Authorised Indian Representative |
| Importer | Verify that the overseas supplier holds a valid BIS licence covering the exact model being imported |
| Brand owner using a contract manufacturer | Ensure the factory holds the licence for the certified models and that brand authorisation is in order |
| Export-only manufacturer | Check that the goods fall within the Order's export exemption before relying on it |
- Licence is held by the Indian manufacturer
- BIS inspects the factory in India
- Samples tested at a BIS-recognised laboratory
- Shorter overall timeline
- Small and micro enterprises get later start dates
- Licence is held by the foreign manufacturer
- An Authorised Indian Representative is appointed
- BIS inspects the overseas factory
- Longer timeline because of inspection scheduling
- Importers must buy from BIS-licensed manufacturers
Documents Required
Missing or inconsistent documents are the most common reason applications stall. Prepare the following before filing:
- Business documents — company registration or Udyam certificate, GST registration, and proof of the manufacturing premises.
- Authorised signatory — board resolution or authorisation letter with identity proof. Foreign manufacturers also submit the Authorised Indian Representative appointment.
- Factory details — layout plan, manufacturing process flow chart, and list of plant, machinery and production equipment.
- Testing and quality control — list of in-house test equipment with calibration certificates, and the quality-control plan covering incoming, in-process and final checks.
- Product documents — model list, ratings, circuit diagram, bill of materials and critical component list including cell, charger and adaptor details.
- Brand and packaging — trademark proof and packaging artwork showing ISI Mark placement.
- Samples and test request — samples and the test request to a BIS-recognised laboratory.
- Declarations and undertakings — BIS-format declarations signed by the authorised signatory.
Timeline and Cost Factors
The figures below are indicative. Your actual timeline depends on document readiness, the number of models, laboratory availability and inspection scheduling.

Exemptions and Relaxations
The Order includes several carve-outs. Use them only after confirming that your situation fits the wording precisely.
The Order does not apply to goods manufactured domestically for export. Products sold in India remain fully covered.
Manufacturers of household appliances may import up to 200 units a year for research and development. These units cannot be sold and must be recorded year-wise.
A manufacturer who is BIS-certified or has applied for certification may sell declared stock for up to six months from the implementation date, subject to a declaration to BIS.
Small enterprises comply from 1 January 2027 and micro enterprises from 1 April 2027.
Post-Certification Obligations
- Use the ISI Mark exactly as licensed — on the product, rating label, packaging and manual.
- Keep routine tests and records — electric strength, insulation, charging and functional checks and marking verification, with instruments calibrated on schedule.
- Inform BIS before changes — any critical component change (cell, charger, motor, UV-C or ionizer module) or design revision needs prior intimation, and new models may need to be added to the licence.
- Support surveillance — market sample testing and factory audits.
- Renew on time — licences are granted for a fixed validity and must be renewed before they lapse.
Common Non-Conformities for Battery Operated Air Purifiers
Missing overcharge and short-circuit protection, or an uncertified adaptor. Fix the power chain before sampling.
Casing or battery area runs too hot in a compact enclosure. Review airflow, spacing and component placement early.
Fingers can reach the fan when a filter door is opened. Add guards and interlocks.
Ionizer ozone or UV-C leaking past a filter door. Measure before testing and switch the lamp off when the door opens.
Missing DC voltage, battery or adaptor details on the label, or weak label durability.
Missing circuit diagrams, critical component lists or calibration certificates delay the application and factory inspection.
Penalty for Selling Without the ISI Mark
Once the Order applies to you, air purifiers without a valid BIS licence and ISI Mark cannot be lawfully placed on the Indian market. Contravention is punishable under the Bureau of Indian Standards Act, 2016. Consequences can include fines, imprisonment and seizure of non-conforming goods. Imported consignments without a valid licence and marking also risk being held at customs. Note that the ISI Mark certifies electrical safety only; claims such as CADR or HEPA grade need separate performance test reports.
