We wish to reaffirm that the only laboratory authorized by the Rabbinate to check for shaatnez is the “KAJ Shaatnez Inspection Laboratory,” (K’hal Adath Jeshurun) led by Rabbi Kalman Strauss.

We have become aware that there is another non-shaatnez label being used that bears the words “Approved by KAJ.” This label is absolutely unauthorized. The Rabbinate takes no responsibility for the non-shaatnez status of any garments bearing such a label.
