These guidelines have been published to assist national laboratories and other relevant scientific institutions in obtaining, in a timely fashion, the reference standards that they require. They address some of the most frequently encountered difficulties and provide guidance on how to overcome obstacles. They are intended for use by laboratories that are in need of reference standards and by competent national authorities that are responsible for the control of drugs and precursors and that issue the import and export authorisations required to exercise that control.
