The International Tissue Technical Advisory Group (ITTAG) was established in 2017. ITTAG focuses on tissues, apart from ocular tissues, across all regions. It provides direction and support to the activities of the European Tissue Technical Advisory Group (ETTAG) and the North American Tissue Technical Advisory Group (NATTAG).

The Membership comprises Technical Experts in human tissues and Representatives appointed by organizations involved in tissue banking.

In addition to members, liaisons attend meetings. Liaisons are from regulatory authorities or other groups interested in ISBT 128.

Other persons interested in the work of the ITTAG may attend meetings as observers at the discretion of the chairperson.

ITTAG last met on July 2 to discuss new terminology and the draft of a briefing paper on the concept of standardized labeling.
