National Refrigerants has identified illegal and potentially non-compliant R1234yf refrigerant cylinders circulating within the UK market.
Investigations indicate that these cylinders originated from China and may contain illegally manufactured or otherwise unauthorised R1234yf refrigerant. Analysis suggests that the refrigerant may lack important stabilising additives designed to protect charging equipment and hose assemblies, increasing the risk of contamination, fouling, and damage to service equipment. As a result, businesses should exercise caution when sourcing refrigerant and be aware of the risks associated with illegal R1234yf cylinders.
Further concerns have been identified regarding cylinder compliance. Reported issues include conflicting tare weight markings, missing contents weight information, and product labelling and traceability details that may not meet UK compliance requirements. Potential non-compliance may also exist in relation to HMRC import regulations and UK Weights & Measures requirements.
In addition, the cylinders do not display the required UK Transportable Pressure Equipment (TPE) conformity marking (ρ). Cylinders manufactured or placed into service in the UK after 2021 must carry this marking and, without it, cannot legally be used in the UK.
National Refrigerants strongly advises businesses not to purchase or use these cylinders and to report any suspected illegal or non-compliant products to the relevant authorities, including Trading Standards and the Environment Agency. Businesses that encounter suspected illegal R1234yf cylinders should take immediate steps to verify product authenticity and compliance.
