The Bureau of Indian Standards (BIS) is the statutory body empowered by the Bureau of Indian Standards Act 2016 under the Ministry of Consumer Affairs, Food and Public Distribution, Government of India. It administers conformity assessment schemes ensuring industrial products comply with rigorous safety, environmental, and quality standards.
Under BIS Scheme-I (Product Certification Scheme), manufacturers receive an official Certification Marks Licence (CML) granting the legal right to affix the iconic ISI Mark to certified products and packaging.
For domestic manufacturers in India, applications are processed via two specific administrative routes: Option 1 (Normal Procedure) and Option 2 (Simplified Fast-Track Procedure). Both options verify that the factory possesses complete in-house testing equipment, qualified quality personnel, and conforms to the specified Scheme of Testing and Inspection (STI).
Over 650+ product categories—ranging from steel bars (IS 1786), cement, chemical polymers, electrical appliances, toys, and cables—are covered under mandatory QCOs. Producing, storing, or selling non-certified goods in India carries severe civil and criminal penalties under Section 29 of the BIS Act.
Under Quality Control Orders issued by DPIIT, Ministry of Steel, and Ministry of Heavy Industries, the following high-demand products must hold an active CML number:
| Category | Indian Standard (IS) | Product Scope | Mandatory Testing Focus |
|---|---|---|---|
| Steel & Construction | IS 1786 / IS 2062 | High Strength Deformed TMT Bars & Structural Steel | Yield stress, bend/rebend, carbon equivalent % |
| Cement Products | IS 269 / IS 1489 | Ordinary Portland Cement (33/43/53 Grade), PPC | Compressive strength, fineness, consistency, Le-Chatelier sound |
| Electrical Cables | IS 694 / IS 1554 | PVC & XLPE Insulated Working Cables up to 1100V | Conductor resistance, spark test, thermal stability, spark test |
| Household Appliances | IS 302-2-3 / IS 302-2-21 | Electric Irons, Storage Water Heaters (Geysers) | Leakage current, earthing continuity, pressure withstand |
| Packaged Water | IS 14543 / IS 13428 | Packaged Drinking Water & Natural Mineral Water | Microbiological count, total dissolved solids, pesticide residues |
| Toys & Child Goods | IS 9873 / IS 15644 | Safety of Toys (Mechanical, Electrical, Chemical) | Heavy metals, small parts test, sharp edge hazard, flame resistance |
BIS allows domestic plants to choose between two application routes depending on urgency and lab testing readiness:
Application is submitted first without pre-testing. BIS officers visit the plant, draw samples during audit, and send them to an approved laboratory.
Samples are pre-tested at a BIS-recognized NABL laboratory beforehand. Test report is submitted alongside the application on Manakonline.
IS Standard Gap Audit: Verifying product parameters against relevant Indian Standards & QCO circulars.
In-House Testing Setup: Procuring required testing machines, standard gauges, and calibrating instruments.
Manakonline Submission: Online application filing with manufacturing flow, machinery list, and QC manuals.
Inspection Handholding: Accompanying BIS inspecting officers during on-site physical evaluation.
Grant of CML License: Receipt of 7-digit CML number, STI acceptance letter, and label marking permission.
Unlike simple trade registrations, obtaining a BIS ISI Mark license requires a fully operational in-house testing laboratory situated inside the factory premises. BIS does not allow outsourcing of routine testing unless specific equipment exemptions are formally granted in the Product Manual.
Every Indian Standard is accompanied by a designated Scheme of Testing and Inspection (STI) that stipulates testing frequencies, sampling sizes, and acceptable quality levels (AQL).
All measuring and testing instruments must have valid calibration certificates traceable to NABL or national standards bodies.
The plant must employ at least one full-time qualified testing chemist/engineer holding a relevant degree (B.Sc, B.Tech).
Systematic maintenance of raw material inspection logs, daily routine test registers, and non-conforming batch disposal logs.
The following verified documents must be submitted on the Manakonline portal:
Certificate of Incorporation / Partnership Deed, MSME Udyam registration, Factory License, and GST Certificate.
Factory premises ownership deed or registered lease agreement, alongside floor layout plan demarcating testing lab and storage.
Inventory of installed plant machinery, production capacity, machine serial numbers, and process flow diagram.
Detailed list of testing apparatus specified under the IS code, with valid NABL calibration certificates.
Registered trademark certificate or official brand authorization letter if manufacturing for external brand owners.
Appointment letters, qualification degrees, and experience records of in-house quality personnel plus raw material test certificates.
1. Portal Registration: Create credentials on the official portal (www.manakonline.in) under Product Certification Scheme.
2. Standard Mapping: Select the applicable Indian Standard (IS Code) and choose between Option 1 or Option 2.
3. Document Upload: Upload verified PDFs of plant layout, machinery list, test equipment calibration, and QC staff credentials.
4. Fee Settlement: Pay official application fees directly via government payment gateway.
5. Verification Audit: Coordinate with nominated BIS Branch Office inspecting officer for physical on-site audit.
ISI licences are initially valid for 1 or 2 years and can be renewed for up to 5 years. Renewal applications must be submitted 1 month before expiry:
