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 membership program that offers individuals a path for global collaboration and participation in various projects, conferences and Division 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.


READ about it in CI …  “IUPAC offers an Open Door to Chemists of the World – A Program Revisited, by Colin Humphris, CI Apr 2018, pp. 26-28 <>

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 2022, almost 1,000 chemists from 40 countries registered as Affiliate Members.

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 all 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.

Objectives of the Affiliate Membership Program

  1. To maximize the participation of chemists world-wide in the affairs of IUPAC and to disseminate information about IUPAC, its activities, and its output to a much wider audience globally.
  2. To provide a broader personal contact base for IUPAC to chemists who are not recorded as active members of IUPAC bodies identified in its Divisions and Committees.
  3. To promote a wider contact of IUPAC with Chemical Societies and other chemistry organizations by encouraging them to operate an Affiliate Program with IUPAC.
  4. To provide a route for contact with individual chemists in countries without a Chemical Society (or one with insufficient resources to operate a program) by encouraging them to become affiliated directly via the IUPAC Secretariat.

The Affiliate Membership Program 2022

The Affiliate Membership Program will continue as a vital part of IUPAC with benefits to chemists globally. Currently, there are chemists from 40 different countries that participate in the program.

IUPAC believes that the improvements made in the program in 2018 are significant because they improve the value to Affiliate Members in the Union through enhanced opportunities for them to participate in the activities of the Union and through discounted pricing for publications, conferences and workshops.

The key aspects of the Affiliate Membership Program are:

  1. Affiliate Members from both NAO and non-NAO countries are eligible to be nominated as candidates for Associate Member positions in Division elections and for appointment to Standing Committees. Affiliate Members who are current for 2022-2023 may participate in the nomination process via self-nomination to Associate Member positions on both IUPAC Divisions and Standing Committees, irrespective of country of residence.  If elected, they are required to to maintain their AMP status for the following biennium.
  2. Affiliate Members may participate in IUPAC projects, including development and leadership of project proposals and as members of project task groups.
  3. Affiliate Members can receive a 10% discount on registration fees for IUPAC endorsed conferences and symposia. Affiliate members can receive a 25% discount on IUPAC books.
  4. Affiliate Members receive access to Chemistry International, and are able to download a full PDF version of quarterly issues. The IUPAC magazine, Chemistry International (CI), informs members of the various IUPAC activities and conferences. IUPAC no longer offers a print copy of CI.
  5. Affiliate Members receive their documentation via the IUPAC website and through their Member Profile page. They are able to download a certificate of membership, an Affiliate Membership card and a letter signed by the IUPAC Executive Director. The membership card has a membership number that identifies an individual as an AMP member of IUPAC.

Administration and Membership Fees

The AMP is administered in many countries and some regions through an AMP Coordinator. For IUPAC member countries, the coordinator is appointed by the NAO. For non-member countries the coordinator will be appointed by a recognized Chemistry Society, agreed by IUPAC.

To become an IUPAC affiliate, review your options here and JOIN.

AMP Membership is USD 50.00 per year, including digital access to CI.

If you are already an Affiliate Member through a coordinator, your National Adhering Organization or National Chemical Society will inform you how to renew your membership.

The Affiliate Membership Program operates on a calendar year, and those who join the Affiliate Program will retain their status until December of that year. For your interest in participating as an AMP Coordinator: Please contact the Executive Director at the IUPAC Secretariat by email: [email protected].
