List of ISI-Certified Companies for Importers (Updated 2026)

If you’re importing electronics, appliances, cables, or any product that falls under India’s mandatory BIS/ISI certification scheme, you need to know which manufacturers are already certified before you place an order, not after your shipment gets stuck at customs.

Below is our updated list of ISI-certified companies, along with how to read it, how to verify a supplier’s certification is still valid, and what to do if your supplier isn’t on the list yet.

What Is the ISI Mark and Why Does This List Matter?

The ISI mark is India’s mandatory quality certification, issued by the Bureau of Indian Standards (BIS), for products considered essential to consumer safety think electrical appliances, cement, LPG cylinders, helmets, and electronics. If a product category falls under the mandatory list and your supplier doesn’t hold valid ISI certification, your shipment can be seized, rejected, or returned at Indian customs, regardless of product quality.

For importers sourcing from China or elsewhere, this creates a specific risk: many overseas factories manufacture excellent products but have never registered for ISI certification, because it isn’t required in their home market. Checking this list before you place a purchase order can save you weeks of delays and the cost of a rejected shipment.

Who Needs to Check This List?

• Importers bringing in electronics, appliances, or electrical components from China or other countries
• First-time importers unfamiliar with India’s BIS/ISI compliance requirements
• Sourcing agents vetting factories on behalf of Indian buyers
• Anyone who has been asked by a supplier “do we need ISI certification for this?”

If you’re unsure whether your specific product category requires ISI certification at all, see our complete list of products requiring mandatory ISI marking before going further.

How to Read This List

Each entry in the downloadable list includes:

• Company/manufacturer name
• Product category covered under their certification
• License number issued by BIS
• Certification status (active/renewal pending)

A company appearing on this list is certified for the specific product category listed next to their name not for every product they manufacture. Always cross-check that your exact product falls under their certified scope, not just their company name.

How to Verify a Supplier’s ISI Certification Is Genuine

A company appearing on a list including this one isn’t a substitute for verifying certification directly. Before finalizing an order:

1. Ask your supplier for their BIS license number and cross-check it against the official BIS CARE portal.
2. Confirm the certified product category matches your order exactly a supplier certified for “LED lamps” isn’t automatically certified for “LED drivers.”
3. Check the certification expiry/renewal date. Licenses lapse, and an outdated PDF list (including ours) can miss a recent change.
4. Get the certificate copy in writing as part of your purchase agreement, not just a verbal confirmation.

What If Your Supplier Isn’t ISI-Certified?

This is more common than most first-time importers expect. If your preferred factory doesn’t hold ISI certification for your product category, you generally have three options:

• Apply for certification on their behalf through BIS’s Foreign Manufacturer Certification Scheme (FMCS) a process that typically takes several weeks and requires product testing.
• Switch to an already-certified manufacturer for that product category, even if it means a new supplier relationship.
• Work with an import agent who can manage the certification process and supplier vetting simultaneously, so it doesn’t stall your launch timeline.
