BIS certification is mandatory for low speed food grinding machines 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. Low speed food grinding machines 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 low speed food grinding machine is a motor-driven grinder that works at low speed, mainly for domestic and similar use, to grind grains, pulses, spices and batter. Demand is growing with modern kitchens, cloud kitchens and food-processing units. Because the appliance combines mains power, a continuously running motor, water or wet food and moving grinding parts, poor construction can cause electric shock, overheating, fire or mechanical injury.
The 2026 Quality Control Order for household and similar electrical appliances makes BIS certification compulsory for this product. Manufacturers need a BIS licence and the ISI Mark. Importers and brand owners must source only from BIS-licensed manufacturers. This guide explains what the Order requires, which standard applies, what testing involves and how to plan your certification.

Is BIS Certification Mandatory for Low Speed Food Grinding Machines?
What Is BIS Certification for Low Speed Food Grinding Machines?
BIS certification is the licence and ISI Mark that the Bureau of Indian Standards grants once a grinding machine 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. Once the Order applies to you, a low speed food grinding machine 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 adds requirements written for a specific appliance group. BIS has also issued a product manual with grouping guidelines for the variety "Low Speed Food Grinding Machine".
Products Typically Assessed as Low Speed Food Grinding Machines
Motor-driven low speed grinders used to grind grains, cereals and pulses.
Low speed grinders, typically with stone or roller grinding parts, used to prepare batter and pastes.
Low speed units used to grind spices and similar dry food material.
Units used in restaurants and small food-processing set-ups, where they fall within the standard's scope and voltage limits.
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 Low Speed Food Grinding Machines
Samples are tested at a BIS-recognised laboratory against IS 302 (Part 1):2024 and the applicable particular requirements. The exact test plan depends on the edition in force and your model's construction. Testing generally falls into these groups:
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 machine, rating label, packaging and manual.
- Rating label — rated voltage and frequency, input power, class of protection, model or type, and manufacturer name, address and brand.
- Safety instructions — safe loading, keeping hands and utensils away from moving parts, cleaning with the supply disconnected, and service guidance.
- Special parts — compatibility notes where detachable cords or special plugs are used.
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 a low speed food grinding machine under the Order, identify the IS 302 parts that apply, and check which implementation date applies to your enterprise.
Group models by rating and construction. Freeze the motor, switch, capacitor and power cord 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.
