➡️ This may indicate a new phase in the illegal refrigerant market.
With HFCs, much of the illegal traffic in Europe has been linked to quantities entering the market outside the quota framework.
In many cases, the question was:
✔️ is this product entering the market through the authorised regulatory channel?
➡️ With HFOs, the issue can be different.
Especially
for high-value patented products such as HFO-1234yf, the question is
not only whether the product is physically available.
The question is also:
▪️ who produced it,
▪️ under which authorisation,
▪️ inside which patent boundaries,
▪️ with which quality control,
▪️ and with which guarantee on composition, purity and stability.
➡️ This is an important difference.
For HFCs, the illegal market has often tried to bypass the regulatory restriction on volumes.
For HFOs, the risk may move toward products that imitate legitimacy.
✔️ A cylinder can have a label.
✔️ A supplier can issue an invoice.
✔️ A commercial offer can look normal.
But these elements do not automatically prove the real origin, production rights or technical integrity of the product.
On LinkedIn, I increasingly see offers for HFO-1234yf
from suppliers that do not clearly explain the origin of the product,
the authorisation framework, or their relationship with the recognized
patent holders.
This absence of clarity is not a detail.
➡️ It shows how parallel markets adapt to the rules.
When regulation controls quantities, the illegal market tries to bypass quantities.
When
technology ownership, patents and production authorisation shape
access, the risk shifts toward counterfeit products and unclear origin.
▪️ For official manufacturers, this is a question of intellectual property, product integrity and brand protection.
▪️ For distributors, the exposure is more operational.
They are close to the market, but they do not always have full visibility on what stands behind a commercial offer.
▪️ For installers and end users, the risk is technical.
A refrigerant is not interchangeable only because the label says the same name.
Composition, purity, stability and compatibility matter.
The next illegal frontier in refrigerants may not look like illegal traffic.
❗ It may look like a legal product.
