Annual Legitimate Requirements (ALR)

In its resolution 49/3, entitled "Strengthening systems for the control of precursor chemicals used in the manufacture of synthetic drugs", the Commission on Narcotic Drugs (in March 2006) inter alia requested member States to provide to the International Narcotics Control Board, annual estimates of their legitimate requirements for ephedrine, pseudoephedrine, 3,4-methylenedioxyphenyl-2-propanone (3,4-MDP-2-P) and 1-phenyl-2-propanone (P-2-P) and, to the extent possible, estimated requirements for imports of preparations containing those substances that could be easily used or recovered by readily applicable means.
Estimated annual legitimate requirements (ALR) for precursors are intended to guide exporting countries about the requirements of importing countries. ALRs are provided through form D and can be amended, as the need arises, by means of an official communication. ALRs relate to calendar years and remain valid until a new estimate is received.
