The mission of the International Antimony Association (i2a) is to inspire product stewardship along the antimony value chain. This mission is accomplished by generating and sharing information concerning the environmental and health safety and societal benefits of antimony and antimony compounds. One of the pillar regulations framing the product stewardship of antimony substances is the European REACH regulation (Regulation (EC) n° 1907/2006). This Regulation sets the rules and steps by which information must be generated, assessed, shared and kept up to date. However, the information is then used as a reference database on antimony and antimony substances in many other regulatory programs and various jurisdictions worldwide. Through a common evidence base, i2a promotes a harmonized risk management and continued safe use of antimony and antimony substances across the value chain and geographical borders.
