Identity and composition

R-1234yf is a single substance, not a blend, and its GWP is published in Annex II, Section 1 rather than in Annex I. That is why it consumes no HFC quota — it remains a fluorinated greenhouse gas, but its leak-check thresholds are counted in kilograms rather than in tonnes of CO2 equivalent.

Who may buy

Fluorinated refrigerant gas is not an ordinary product. Article 11(6) of Regulation (EU) 2024/573 limits who may buy it for installation, maintenance, servicing or repair — and it binds the seller too.

The two declarations available at checkout

Technical use / installation and servicing

A valid F-Gas certificate is required for charging, installation, maintenance, servicing, repair or recovery. At checkout you enter the certificate holder, the number and the issuing country.

Distributor / resale

I am buying the sealed product for resale without carrying out technical work on the gas or equipment. The option is available to a company, sole trader or professional entity.

The declaration is recorded with the order. The details may be checked before dispatch.

This page does not decide whether you may buy. That is settled at checkout, against the declaration you sign.
