Green Cracker QR Verifier
Learn to verify a genuine green cracker step by step — the CSIR-NEERI QR code, the green logo and SWAS/STAR/SAFAL marks. Free verification guide.
Short answer:
- A genuine box shows two things together: the green CSIR-NEERI "Green Fireworks" logo and a QR code specific to that product. One without the other proves nothing.
- Scan the code with your phone camera or the "CSIR NEERI Green QR Code" app (Google Play Store); a real scan opens the manufacturer, product details, certificate, and a reference to the Supreme Court order.
- A blank scan, a broken link, or details that don't match the box means it isn't certified — put it back.
- Certified stock is built to one of three named formulations: SAFAL, STAR, or SWAS.
How to use it
Run the four checks below on any box before you buy, or the moment a delivery lands, rather than trusting a "green" name printed on the packaging. Each step mirrors how CSIR-NEERI itself defines a valid check, so a pass on all four confirms the box and a fail on any one means you stop there. Keep it handy for in-person shopping where scanning every box in advance isn't practical, and see the full tools library for the timing checker, decibel finder, and other calculators that pair with this one.
The four-step verification walkthrough
| Mark | Stands for | What makes it distinct |
|---|---|---|
| SAFAL | Safe Minimal Aluminium Cracker | Water held in a zeolite adsorbent, released as dust-suppressing vapour on ignition |
| STAR | Safe Thermite Cracker | Thermite-style reaction against a metal-oxide oxidiser, lower ignition temperature |
| SWAS | Safe Water Release | Water pre-loaded in hydrogel or calcium-peroxide additives, reacts with lime on burn |
Work through these in order; skipping ahead to the scan without checking the logo first is the most common way a fake slips past.
- Find the logo. Look for the circular "Green Fireworks / CSIR-NEERI-India" badge with a PESO licence reference and a certificate number printed on the box. No logo means the product fails right here, whatever the name on the label claims.
- Find the QR code next to it. It should be printed cleanly, not smudged, cropped, or visibly reused from another pack.
- Scan it. Point your phone camera at the code, or open the "CSIR NEERI Green QR Code" app from the Google Play Store and scan through that instead.
- Read what opens. A genuine scan shows the manufacturer's name and unit, the product name and variant, the formulation category (SAFAL, STAR, or SWAS), the certificate's details, and a reference to the Supreme Court's 2018 order. If the page is blank, the link fails to load, or the details don't match the box in your hand, treat it as uncertified and ask for a different batch.
None of the three changes the bang or the flash. CSIR-NEERI's own figures put all three in the same 100–120 dBA range as conventional crackers of the same type; the certification targets particulate matter, not sound or spectacle.
Why the check exists
The Supreme Court's judgment of 23 October 2018 (Writ Petition (Civil) No. 728 of 2015) permits the manufacture and sale of certified green crackers. The National Green Tribunal's orders of 9 November and 1 December 2020 (O.A. No. 249/2020) separately restrict use to green crackers in cities and towns where air quality is moderate or below. The logo-plus-QR pair is the mechanism that lets a buyer, or an enforcement officer, confirm a box actually clears that bar rather than just claiming to. For the full comparison of SAFAL, STAR, and SWAS chemistry and the PESO/CSIR-NEERI split of who certifies what, see green cracker certification marks explained. The complete scan-by-scan walkthrough, including what to do when a code fails, is in NEERI QR code for green crackers explained.

Frequently Asked Questions
Is the logo alone enough to prove a cracker is green-certified?
No. The logo signals intent to be certified, but only a QR code that resolves to matching product details confirms it against CSIR-NEERI's own record. A logo with no scannable code, or a code that doesn't match the box, isn't proof.
Do I need a special app to scan the code?
Not strictly. A standard phone camera reads it. The "CSIR NEERI Green QR Code" app on the Google Play Store is there for cases where your camera app doesn't read QR codes directly.
What if the QR code doesn't scan or opens to nothing?
Treat the box as uncertified. A working genuine code resolves to product and certificate details; a blank page, an error, or a mismatch means it hasn't passed verification.
Are SAFAL, STAR, and SWAS different certification tiers?
No. They're three separate chemistries CSIR-NEERI engineered to hit the same particulate-matter reduction bar, applied across different product types. None ranks above another.
