In India’s compliance landscape, one wrong certification can cost months of delay.
Last year, a Pune-based machinery manufacturer had its shipment held at customs for nearly two months — the reason? The company applied for an ISI Mark license, but its product actually fell under the new BIS OTR (Scheme-X) framework.
This confusion is increasingly common as India transitions toward unified product regulations under the Omnibus Technical Regulation (OTR). Whether you manufacture, import, or sell equipment, understanding the difference between OTR and ISI Mark is crucial to avoid costly mistakes.
The Bureau of Indian Standards (BIS) is India’s national standards body under the BIS Act, 2016. It ensures that products sold in India meet safety, reliability, and performance benchmarks.
BIS operates several certification schemes:
The ISI Mark is the oldest and most recognized product safety symbol in India. It ensures that the product meets the Indian Standard (IS) for its category.
In simple terms, ISI certification = mandatory approval for products explicitly listed in government notifications.
The Omnibus Technical Regulation (OTR) is BIS’s latest framework for cross-sector product compliance. Introduced in 2022 and scaled through 2024-25, OTR consolidates scattered safety and quality approvals into a single certification route.
It is designed for:
Under OTR, applicants obtain certification once and can demonstrate compliance with multiple BIS or sectoral standards through a single license.

Until recently, manufacturers had to navigate several schemes — ISI for certain goods, CRS for electronics, and FMCS for imports. This led to duplication, higher costs, and inconsistent standards.
The BIS OTR framework was introduced to:
According to DPIIT (2024), more than 1,200 product categories are expected to migrate to OTR by FY 2026, replacing multiple scheme-specific registrations.
| Feature | BIS OTR (Scheme-X) | ISI Mark (Scheme-I) |
|---|---|---|
| Objective | Unified multi-sector compliance under Omnibus Technical Regulations | Mandatory safety and quality assurance for notified products |
| Applicable To | Manufacturers & importers whose products aren’t yet under ISI/CRS | Domestic manufacturers of products under QCOs |
| Testing Process | Type testing + factory evaluation by BIS or accredited labs | In-plant sample testing + BIS surveillance audit |
| Certificate Validity | 2–5 years (renewable) | 1 year initial + renewals up to 5 years |
| Coverage | Industrial machinery, EV components, composite systems | Consumer goods, construction materials, electrical products |
| Foreign Manufacturers | Covered through FMCS-OTR route | Covered under FMCS (Scheme I) |
| Product Marking | OTR Mark / QR code linked to BIS portal | ISI logo with IS number |
| Legal Basis | BIS (Conformity Assessment) Regulations 2018 + Scheme-X Guidelines 2025 | BIS Act 2016 + Quality Control Orders (QCOs) |
Interpretation:
If your product isn’t in a QCO list but is subject to an Indian Standard, the OTR route is usually the right pathway to compliance.
Example:
A solar-powered industrial fan combines mechanical and electrical components. Since it spans renewable energy and electrical machinery categories, it qualifies under OTR (Scheme-X) instead of a traditional ISI mark.
| Particulars | Fee (₹) | Remarks |
|---|---|---|
| Application processing | 1,000 – 2,000 | Non-refundable |
| Product testing | 20,000 – 50,000 | Depends on product type |
| Annual license fee | 1,000 / product | Payable to BIS |
| Renewal (after 5 yrs) | 2,000 + testing charges | Subject to review |

Average approval time: 40 – 45 days after submission of complete documents.

According to BIS internal reports (2024), average OTR approval time is about 45 days, compared with 60–75 days for separate multi-scheme licensing earlier.
Operating without valid BIS certification—whether ISI or OTR—can invite serious penalties under the BIS Act 2016 and DGFT regulations:
Maintaining the correct license also protects brand trust and enables smooth B2B sales to government or PSU buyers.
The next phase of BIS modernization (2025 – 2027) aims to:
By FY 2026, most industrial and hybrid-technology goods will likely be certified under OTR (Scheme-X) instead of individual ISI routes.
| Product Type | Example | Certification Required | Relevant Scheme |
|---|---|---|---|
| Consumer goods under mandatory QCO | Pressure cooker, cable, helmet | ISI Mark | Scheme I |
| Electronic & IT products | Laptop, monitor, printer | CRS | Scheme II |
| Industrial machinery / hybrid systems | Compressor, panel, EV charger | OTR Certification | Scheme X |
| Imported goods for India | Foreign electronics, equipment | FMCS + OTR | Scheme X (FMCS route) |
Imagine investing ₹ 20 lakh in product testing under the wrong scheme—only to learn your category moved under OTR.
That’s why expert pre-screening of your product category saves both time and compliance cost.
In 2025, the question isn’t whether you need BIS certification — it’s which one fits your product.
Choosing the correct path—ISI for mandated goods or OTR for new and composite products—ensures smooth licensing, faster market entry, and full legal protection.
BIS certification is not paperwork — it’s your product’s passport to the Indian market.
