A comprehensive, practical roadmap for manufacturers seeking ISI mark certification under Bureau of Indian Standards (BIS) Scheme-I. Learn documentation requirements, modern testing facility options, factory audit procedures, and how Sun Associates provides end-to-end consultancy support.
The Bureau of Indian Standards (BIS) operates the Product Certification Scheme (Scheme-I) to grant manufacturers the right to affix the prestigious ISI mark. Compliance demonstrates rigorous conformity to Indian Standards and is mandatory for hundreds of notified industrial products.
Scheme-I is the core licensing framework for tangible industrial and consumer products. It verifies that manufacturing infrastructure, quality control systems, and product parameters consistently meet published Indian Standards.
Line ministries (including Steel, Chemicals, Heavy Industries, and DPIIT) issue mandatory QCOs prohibiting the production, import, storage, or sale of non-certified products. Adherence ensures seamless commercial operation and avoids penalties.
Each product standard is accompanied by an official BIS Scheme of Inspection and Testing (SIT). It outlines mandatory sampling frequencies, testing parameters, maintenance of quality logs, and criteria for batch conformity.
Under recent BIS policy directives, manufacturers can explore flexible testing options such as shared cluster facilities or eligible external laboratories, eliminating the assumption that an exhaustive in-house laboratory is universally compulsory for every product.
Navigating BIS certification requires a structured approach from initial gap analysis to the formal grant of license. Here is how the process works in practice.
Verifying applicable standards, amendments, and raw materials
The process begins by identifying the active Indian Standard (IS code) governing your product and checking relevant QCO notifications. Your manufacturing line, machinery capability, and raw material supplier credentials are evaluated against the standard requirements to establish an actionable compliance plan.
Establishing quality verification pathways per SIT requirements
Determine the testing route based on your product's Scheme of Inspection and Testing (SIT) and applicable BIS circulars. Whether using in-house apparatus, shared facilities, or external testing arrangements, all measuring instruments and gauges must hold valid calibration certificates to guarantee test accuracy.
Online application submission with official supporting records
Prepare the comprehensive documentation portfolio required by BIS. The application is filed on the official Manakonline portal, including factory registration documents, process flow charts, machinery lists, testing arrangements, and undertaking declarations.
Physical verification of manufacturing controls and quality processes
BIS inspecting officers visit the manufacturing premises to examine the production setup, verify raw material traceability, review testing facilities, and observe witness testing. During the audit, officers select and seal independent product samples for external laboratory verification.
Third-party verification in a BIS-approved laboratory
The sealed product samples are dispatched to a designated BIS laboratory or BIS-recognized external testing laboratory. The sample undergoes complete testing across all parameters specified in the Indian Standard. The official test report is subsequently submitted to BIS for technical scrutiny.
Official licensing and ongoing surveillance compliance
Upon successful scrutiny of the factory audit report and independent test results, BIS grants the Certificate of Marks License (CML). The manufacturer receives a unique 7-digit CML number, allowing the official application of the ISI mark on conforming production batches.
Recent updates from the Bureau of Indian Standards provide flexible compliance pathways, allowing manufacturers to choose the most practical and cost-effective testing arrangements.
Setting up testing apparatus directly within your factory premises. This traditional route offers immediate batch clearance capabilities, complete operational autonomy, and routine quality verification by your own plant technicians.
Under recent BIS policy directives, small and medium enterprises (MSMEs) in industrial clusters can leverage approved shared testing centres or cluster laboratories for capital-intensive testing equipment, substantially lowering initial capital expenditure.
Where permitted by specific Indian Standards and BIS guidelines, manufacturers can enter into formal agreements with recognized external laboratories for testing selected parameters, subject to procedural compliance and formal BIS acceptance.
A well-structured documentation portfolio is critical to avoid unnecessary scrutiny delays or application queries. Sun Associates assists in organizing and drafting every required element.

Scheme-I is the traditional Product Certification Scheme that grants the right to use the ISI mark on manufactured goods. It involves rigorous factory audits, verification of manufacturing processes, and compliance with the Scheme of Inspection and Testing (SIT). In contrast, the Compulsory Registration Scheme (CRS, Scheme-II) is a self-declaration scheme primarily for electronics and IT goods, based on lab test reports without mandatory initial factory audits.
Under updated BIS guidelines (including policy circulars issued on 16 December 2025), an in-house laboratory is no longer universally compulsory for every product. Depending on the applicable Indian Standard and product category, manufacturers may utilize alternative testing arrangements such as shared facilities, cluster laboratories, or eligible external accredited laboratories, subject to stated exceptions and BIS approval.
Typical timelines generally range from 30 to 90 days from application submission to grant of license. The duration depends on factory readiness, completion of documentation, prompt scheduling of the BIS inspection, and the testing duration required by the independent laboratory for product verification.
When the Ministry notifies a product under a mandatory Quality Control Order (QCO), manufacturing, importing, storing, selling, or distributing non-certified stock is prohibited by law. Non-compliance can lead to confiscation of goods, heavy monetary penalties, and legal action under the Bureau of Indian Standards Act, 2016.
A newly granted BIS license is typically valid for one to two years initially. It can subsequently be renewed for periods of up to five years, provided the manufacturer maintains compliance with the Scheme of Inspection and Testing (SIT), pays applicable marking fees, and passes periodic surveillance audits.
Yes. Foreign manufacturers can apply for BIS certification under the Foreign Manufacturers Certification Scheme (FMCS). The process requires nominating an Authorized Indian Representative (AIR) and undergoing physical inspection of the overseas manufacturing premises by BIS officers.
