certko — Compliance. Assured.

Keep your marketplace listings live

Amazon, Flipkart and other marketplaces block listings for notified products without a valid BIS or CRS number. Check your product's status in seconds and certify before a delisting, not after.

Why marketplaces delist non-certified products

Amazon, Flipkart, Meesho, JioMart and other Indian marketplaces actively verify compliance for notified products. Listings for products under a Quality Control Order — toys, pressure cookers, helmets, electronics, appliances, footwear and many more — must display a valid BIS licence or CRS registration number (R-number). Missing or invalid numbers lead to listing blocks, delisting and account health strikes; enforcement drives also remove entire categories overnight.

Seller checklist before you list

  1. Search your product on Certko — by name or HSN code — to confirm whether it is notified and under which scheme (ISI or CRS).
  2. Get the certification in the right name — CRS registrations are per brand and per manufacturing location; reselling someone else's registration is not compliant unless you are an authorised brand seller.
  3. Add the number to your listing — marketplaces provide a compliance field for the BIS/CRS number; the printed label on the product and packaging must match.
  4. Watch upcoming QCOs — products that are legal to sell today can become mandatory in months. Our QCO Alerts page lists notified enforcement dates so you can certify before the deadline instead of after a delisting.
  5. Importing to sell? Customs also checks certification for notified goods — uncertified consignments are held or re-exported.

What Certko does for marketplace sellers

We confirm your exact product's status in minutes, run testing at the most economical approved lab, complete the CRS or ISI process, and hand you the number in the format marketplaces expect. If your listing was already taken down, we prioritise the fastest compliant route to reinstatement. Start with a free product check — search above or send us your listing link.

Frequently Asked Questions

Amazon asked for a BIS number on my listing. Where do I get it?

If your product is notified, the number comes from the BIS licence (ISI) or CRS registration (R-number for electronics). Search your product on Certko to see which applies; the certification is issued to the manufacturer per factory and brand.

My listing was delisted for missing BIS compliance. Can it be reinstated?

Yes — once you hold a valid certification for the exact product and it is added to the listing's compliance field, marketplaces typically reinstate it. We prioritise delisted-seller cases to shorten the downtime.

I import and resell — do I still need certification?

The certification must cover the manufacturer (Indian or foreign) of the product you sell. Importers of notified products must ensure the overseas factory holds BIS certification (FMCS or CRS) — customs and marketplaces both check.

Certko showed me the exact IS standard, real lab prices and a shortlist of labs near my warehouse in one evening. The certification quote I got through them was 30% below what I had been offered elsewhere.

The product testing pages made scope and sample size obvious before we requested a quote. When we did, the proposal matched what we had already budgeted.
