CPV 243 classifies public tenders for inorganic and organic basic chemicals including acids, alkalis, water treatment chemicals and solvents in EU public procurement. Find contracts with Bond.
What does CPV 243 cover?
CPV group 243 (24300000) covers public contracts for inorganic and organic basic chemicals – mineral acids such as hydrochloric acid, sulphuric acid, and nitric acid; alkalis and bases including sodium hydroxide and calcium hydroxide; salts and mineral compounds; water treatment chemicals including coagulants, flocculants, pH adjusters, and disinfection chemicals; organic solvents; and other basic chemical raw materials and process chemicals.
In the public sector, inorganic and organic basic chemicals are procured primarily by water and wastewater utilities for water treatment processes. Sodium hypochlorite, aluminium sulphate, ferric chloride, and pH adjustment chemicals are essential inputs for drinking water treatment and wastewater purification. Swimming pool operators procure water treatment chemicals for pool water maintenance. Chemical laboratories at public universities, research institutes, and inspection authorities require inorganic and organic reagents and solvents. Public cleaning and maintenance operations use alkaline cleaning concentrates and acid descalers. Municipal heating network operators use corrosion inhibitors and water treatment additives.
Within CPV group 240, group 243 covers fundamental chemical building blocks and process chemicals, distinguishing it from group 249 (fine and speciality chemicals) and group 242 (colouring materials). Further information on the CPV system is available from the European Commission (SIMAP) and Regulation (EC) No 213/2008.
Typical Services in CPV 243
- Water treatment chemicals for municipal drinking water and wastewater treatment plants
- Pool water treatment chemicals for municipal swimming facilities
- Inorganic laboratory chemicals for public research and testing institutions
- Process chemicals for public heating networks and industrial facilities
