Notations for Cd stable isotope compositions and the use of reference materials are discussed. It is proposed that Cd stable isotope data should be reported as variations of the 114 Cd/ 110 Cd ratio/ using either the δ 114/110 Cd or ε 114/110 Cd notations. Future publications should report results for BAM‐1012 Cd, the only currently available international Cd isotope reference material. It is also recommended that “Münster Cd” and a range of specified geological reference materials are used as additional reference materials. The final choice of a primary “zero‐delta” reference standard remains the most important outstanding question.
