Who Can Legally Buy Refrigerant? Section 608 and 609 Explained

Refrigerant is not a general-merchandise item. Under Section 608 of the Clean Air Act, the sale of refrigerant in cylinders, cans and drums is restricted to certified buyers — and that restriction covers both ozone-depleting refrigerants such as R-22 and non-ozone-depleting substitutes such as R-410A and R-134a.

Section 608: stationary equipment

A technician holding EPA Section 608 certification can purchase any refrigerant intended for stationary equipment: residential split systems, rooftop packaged units, walk-in coolers, process chillers and everything in between.

Employers can buy as well, provided they can show written evidence that they employ at least one properly certified technician. In practice that means a copy of the certificate on file with the distributor, tied to the trading account rather than to the individual placing each order.

Section 609: motor vehicle air conditioning

Section 609 certification covers motor vehicle air conditioning work. A 609-certified technician can buy refrigerant for vehicle systems, and so can their employer under the same written-evidence rule.

There is an important limit here that catches people out: a Section 609 certification does not allow the purchase of refrigerant intended for stationary equipment, and that restriction applies regardless of container size. A 609 card will not get you a 25 lb cylinder for a walk-in cooler.

The small-can exception

One narrow exception exists. Small cans of non-exempt MVAC refrigerant — containers designed to hold two pounds or less, fitted with unique fittings and self-sealing valves — can still be sold to buyers without certification. This is the exception that keeps DIY car air-conditioning top-up cans on retail shelves.

Everything else in a cylinder, can or drum needs a certification behind it.

What this means when you order from Refrigora

We verify certification before the first order ships. Send your Section 608 or 609 certificate once and it stays on file against your account, so repeat orders and pallet quantities move without you re-sending paperwork each time.

If you are ordering on behalf of a company, send the certificate of the technician you employ along with confirmation of employment. That is the written evidence the rule asks for.

Rules change. Check current EPA guidance for the definitive position before making compliance decisions for your business.
