Individual Members

The IUPAC Affiliate Membership Program (AMP) allows any individual with an interest in IUPAC and IUPAC activities to sustain a relationship with the Union.

The Affiliate Membership Program is an annual application program that offers individuals a path for global collaboration and participation in various projects, conferences and committees of IUPAC.  Further explanation is stated through the AMP objectives and benefits.  To become an Affiliate Member of IUPAC, individuals can apply directly online: JOIN.

At the IUPAC Council meeting at Leuven, Belgium in 1981, IUPAC discussed a plan to establish an Affiliate Membership Program. The intention of the AMP was to engage individual chemists, National Adhering Organizations (NAOs), the International Council of Scientific Unions (ICSU), and Chemical Societies more effectively in the work of the Union. The issues involved were set out first by an ad hoc group and subsequently by a Committee on Affiliate Membership and over the years, were discussed additionally by the Bureau, the Finance Committee, and the Executive Committee. In 1985, at the 32nd General Assembly in Lyngby, Denmark, the AMP plan was approved by Council by majority vote. The first Affiliate Members were enrolled at the beginning of 1986 with the recruitment of 5,500 members in the first year of operation.

In 2019, almost 1,000 chemists from 50 countries registered as Affiliates. Included in this number are nearly 360 sponsored Affiliate members from developing and economically disadvantaged countries.

During 2016 and early 2017, discussions led by the Treasurer and Executive Director, led to proposed changes that would achieve broader global engagement by active chemists and offer the opportunity for younger chemists in NAO and non-NAO countries to engage in IUPAC membership. The proposed changes were discussed at the 155th Executive Committee Meeting, Beijing 8-9 November 2016 and 99th Bureau (virtual) meeting 8 April 2017. A revised Affiliate Membership Program (AMP) proposal was approved at the 49th Council meeting in São Paulo, Brazil in July 2017. The original objectives and intentions of the AMP remain as part of this revised program.
