ISI Mark vs CRS vs FMCS: Which BIS Certification Does Your Product Need?

BIS operates three main product certification schemes, and one of the most frequent questions we receive is: "Which one applies to my product?" The answer depends on what the product is, where it is manufactured, and which Indian Standard covers it. This guide cuts through the confusion.

The Three Schemes at a Glance

• ›ISI Mark (Scheme I) — for domestic manufacturers of industrial, household, and consumer products under mandatory or voluntary IS standards
• ›FMCS (Scheme II) — for foreign manufacturers of any product subject to a mandatory QCO who want to sell in India
• ›CRS (Compulsory Registration Scheme) — for electronics and IT products sold in India, regardless of where they are manufactured

ISI Mark — Scheme I

The ISI Mark under BIS Scheme I is the certification for domestic manufacturers — companies with production facilities inside India. If your product falls under a mandatory Quality Control Order (QCO), you must obtain an ISI Mark before you can manufacture or sell it in India. For non-QCO products, the ISI Mark is voluntary but commercially valuable.

Scheme I involves factory inspection by a BIS officer plus lab testing at a BIS-recognised lab. The licence is product-specific (one IS number, one licence) and renewed annually.

• ›Who: Indian domestic manufacturers only
• ›What: Industrial, household, chemical, textile, and other non-electronics products with an IS number
• ›Process: Application → lab testing → factory inspection → licence
• ›Timeline: 10–18 weeks
• ›Mark on product: ISI logo + IS number + CM/L licence number

FMCS — Scheme II (Foreign Manufacturers)

FMCS is the Scheme I equivalent for manufacturers based outside India. If a foreign manufacturer's product is covered by a mandatory QCO (requiring an ISI Mark), the only legal path is FMCS. There is no way to import a QCO-covered product without it.

The key difference from Scheme I: BIS officers physically travel to the overseas factory for inspection, at the applicant's expense. This makes FMCS significantly more expensive and time-consuming than domestic ISI Mark.

• ›Who: Foreign manufacturers exporting QCO-covered products to India
• ›What: Same product categories as ISI Mark — industrial, household, chemical goods under QCOs
• ›Process: Application + AIR appointment → overseas factory inspection by BIS → lab testing → licence
• ›Timeline: 6–12 months
• ›Mark on product: ISI logo (same mark as domestic ISI) + IS number + CM/L licence number

CRS — Electronics and IT Products

CRS stands apart from both ISI Mark and FMCS because it applies specifically to electronics and IT products under the MeitY notification — and it has no factory inspection requirement at all. Any manufacturer or importer (domestic or foreign) can apply directly.

CRS registration is per product model and valid for 2 years. The mark affixed is "R-CRS" rather than "ISI".

• ›Who: Any manufacturer or importer (domestic or foreign) of electronics and IT products
• ›What: Mobile phones, laptops, LED lights, chargers, power banks, TVs, routers, UPS, and 100+ other electronics categories
• ›Process: Lab testing → BIS Connect portal application → registration certificate
• ›Timeline: 3–8 weeks
• ›Mark on product: R-CRS mark + registration number

Decision Tree: Which Scheme Applies?

• ›1. Is your product an electronics or IT product listed in the MeitY CRS notification? → CRS
• ›2. Is your product covered by a QCO and manufactured outside India? → FMCS
• ›3. Is your product covered by a QCO and manufactured inside India? → ISI Mark (mandatory)
• ›4. Is your product covered by an IS standard but not under a QCO, and manufactured in India? → ISI Mark (voluntary)
• ›5. None of the above? → BIS certification may not be required; verify by searching the IS database

Side-by-Side Comparison

• ›Factory inspection: ISI Mark ✓ (India) | FMCS ✓ (overseas, at your cost) | CRS ✗ (none)
• ›Who can apply: ISI Mark — Indian manufacturers only | FMCS — foreign manufacturers only | CRS — anyone
• ›Timeline: ISI Mark 10–18 weeks | FMCS 6–12 months | CRS 3–8 weeks
• ›Valid for: ISI Mark — 1 year (renewable) | FMCS — 1 year (renewable) | CRS — 2 years
• ›Per model or per factory: ISI Mark — per product/IS | FMCS — per product/IS | CRS — per product model
• ›First-year cost: ISI Mark ₹50K–₹2L | FMCS ₹3L–₹8L | CRS ₹45K–₹85K per model
