Producer
Coster Group S.p.A.
Italian specialty valve and actuator manufacturer (HQ Carnago, Varese, Lombardy; private, family-owned; ~€350M revenue); the third-tier supplier in pMDI metering valves behind Bespak and Aptar Pharma. Coster Group manufactures pMDI metering valves for generic inhaler manufacturers and some branded products, predominantly serving European and Latin American markets. Coster also manufactures aerosol valves for personal care products (hairspray, deodorant) and industrial applications — the same Italian valve engineering company that makes the valve in a can of Axe body spray also makes the metering valve that delivers albuterol in some generic asthma inhalers. Coster's position in the pMDI valve market represents a strategic supply diversification option for pharmaceutical companies seeking alternatives to the Bespak/Aptar duopoly, though its smaller scale and qualification breadth limits uptake.

Did you know2024
Coster Group is predominantly known in the packaging industry as a supplier of aerosol valves for personal care — it makes the valve inside cans of Axe, Pantene hairspray, and countless private-label deodorants. What pharmacists and pulmonologists almost certainly do not know is that the same Varese-based valve engineers who design consumer aerosol dispensers also manufacture pMDI metering valves that deliver precise doses of albuterol and budesonide in generic asthma inhalers. Coster sits behind the Bespak/Aptar duopoly in pharmaceutical aerosol valves but represents the only Italian-engineered option for inhaler manufacturers seeking supplier diversification — the same Coster factory floor produces both the valve in a can of dry shampoo and the metered-dose mechanism inside a rescue inhaler.
Coster Group S.p.A. ↗Origin2023
Coster Group was founded in Carnago, Varese in 1947 by the Coster family, initially producing aerosol valves for Italy's postwar personal care industry. The company grew with the global aerosol boom of the 1960s-70s, supplying valves to hairspray and deodorant brands. In the 1990s, Coster applied its precision valve engineering to pharmaceutical aerosols as pMDI inhalers demanded metering valves with dose accuracy measured in microliters — the same manufacturing discipline that ensures a hairspray valve dispenses consistently translates directly to pharmaceutical dose precision.
