What Harp International does

Harp International Limited is a privately-held UK specialty chemicals company founded in 1991 and headquartered at a 75,000 sq.ft. facility in Pontypridd, South Wales. The company manufactures and distributes a broad portfolio under the HARP® brand covering refrigerants (HFCs, HCFCs, hydrocarbons, HFOs, natural refrigerants such as R290, R600a, R717, and R744), lubricants/refrigeration oils (mineral, PAG, POE, and synthetic HC), foam blowing agents, aerosol propellants, and industrial gases. These products serve the refrigeration and air conditioning industry as the primary segment, with secondary verticals in foam insulation manufacturing, aerosol production, and industrial gas users.

The company's underlying technical assets include a proprietary HARP® brand portfolio with anti-counterfeiting measures, an industry-first cylinder tracking platform (trackmycylinders.com) for F-Gas compliance, the largest standalone refrigerant reclamation plant in the UK, proprietary separation technology under development for halocarbon mixture reclamation, and a BS EN ISO 9001-accredited analytical laboratory for refrigerant and oil testing. Integrated management system certification under ISO 9001:2015, ISO 14001:2015, and BS ISO 45001:2018 underpins regulatory compliance for handling ozone-depleting substances and high-GWP F-gases.

Harp operates a hybrid go-to-market combining direct sales for UK customers, a wholly-owned subsidiary network (Harp USA Inc., Harp Middle East L.L.C., Harp Middle East Qatar LLC, Gaspack Services Ltd), and exclusive distributor relationships spanning 87+ countries across Europe, the Middle East, Africa, Asia, and the Americas. Revenue is generated through one-time product sales across multiple packaging formats (12oz through 208-litre drums) supplemented by professional service revenue from refrigerant reclamation, analytical testing, and cylinder testing/refurbishment. Pricing is opaque, with customers directed to contact sales representatives for quotes.
