How can you tell genuine refrigerant from counterfeit?
Buying refrigerant? We supply Stallion and Refron (GFL) in factory-sealed cylinders from Hyderabad.
Why refrigerant attracts counterfeiters
The product is a pressurised gas nobody can eyeball: identical cylinders, invisible contents, verification requiring a lab. Add a price gradient — quota-tightened R-22, duty-affected R-134a (the 2025 ADD): and the fraud writes itself: cheap hydrocarbons or R-40-cut blends in convincing livery. Chemours and other majors run formal brand-assurance programmes precisely because the problem is real and global; the injury record is in why fakes are dangerous.
The four-layer check
| Layer | What to verify |
|---|---|
| 1 · Source | Registered, established seller — for R-22, demand the ODS registration; run the four-step seller check |
| 2 · Documents | Manufacturer SDS for the exact brand, GST invoice naming brand and product, batch/COA where applicable (full set) |
| 3 · Cylinder | Intact factory seal and valve; crisp brand label with batch; stampings consistent; no scraping or repainting (colour proves nothing) |
| 4 · Brand features | Holograms/security codes verified through the brand's own channel where offered |
Red flags that end the conversation
A price far below the market for a quota-controlled gas; "unbranded but same quality"; refilled disposables (flatly illegal); sellers allergic to paperwork; loose or reused seals; labels that misspell their own brand. Any one of these is sufficient reason to walk. The downside is not a weak batch but a flammable or system-killing one.
When suspicion survives the paperwork
Field verification exists: a refrigerant identifier reads composition at the valve, and pressure–temperature sanity checks catch gross substitution (a cylinder's pressure at known ambient should sit on the fluid's curve — the physics from the pressure guide). For consequential volumes, a lab GC against AHRI 700 limits settles it. Our own position is the boring one that works: factory-sealed product from the brands we are appointed to carry, papers attached, every time — see the compliance page.
The economics of the fake — and why scarcity decades are peak risk
Counterfeiting follows margin, and refrigerants in a phase-down era offer margins most contraband would envy. The cost structure explains the behaviour: hydrocarbon blends or R-40-cut mixtures cost a fraction of legitimate fluorochemical production, cylinders and label printing are commodity items, and the product's identity is invisible without instruments, so a fake sold at a mere 15–20% discount to market still multiplies the fraudster's outlay several times over. Now add the demand curves this site documents: R-22 on a shrinking quota staircase, R-134a under a reference-price duty, high-GWP HFCs facing Kigali repricing — every force that lifts legitimate prices widens the counterfeit margin in lockstep, which is why enforcement history worldwide shows fake-refrigerant waves cresting precisely during transition decades. The strategic consequence for buyers is that authenticity discipline must scale with price, not relax under cost pressure: the moment a quoted price makes you exhale with relief is the moment the four-layer check earns its keep, because 'too cheap for the quota environment' is not a bargain signal but a composition question. Institutional buyers can go one step further and make the discipline contractual (specifying registered-seller sourcing, branded sealed product and batch documentation in AMC and procurement terms) which converts every rule on this page from good practice into an enforceable clause, and quietly prices the grey market out of your supply chain.
