The idea of ​​establishing a mechanism for harmonization of standards among Islamic countries was first brought to the agenda in the COMCEC Meeting held in 1984.

The Statute of SMIIC, prepared in this scope, was adopted at the 14 ^th COMCEC Meeting held in 1998 and submitted for signature of member states for the first time at the 15^th COMCEC Meeting held in İstanbul one year later.

The Statute entered into force in August 2010 after the fulfilment of the ratification requirement of ten OIC member states and SMIIC started its activities in Istanbul as an affiliated organ of the OIC.

The Secretary General of SMIIC is İhsan Övüt. Mr. Övüt was first elected to this post at the 7^th SMIIC General Assembly Meeting in Istanbul on 20 November 2014 and re-elected at the 12^th General Assembly Meeting held in Istanbul on 26 November 2017.
