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.
Governments are obliged to report annually on substances frequently used in the illicit manufacture of narcotic drugs and psychotropic substances and should complete Form D and submit it by the deadline of 30 June each year. Governments are urged to complete all the sections of the Form and to provide comprehensive, mandatory information on methods of diversion, stopped shipments and illicit manufacture.
The Red List is the list of chemicals frequently used in the illicit manufacture of narcotic drugs and psychotropic substances under international control.

This guidance document provides a collated list of options and concrete actions to address the proliferation of non-scheduled chemicals and designer precursors, including through international cooperation. It is an important resource for governments looking to implement tried or feasible practices or use this document as a basis for cooperation globally. This brochure is a result of a series of activities and consultations with Member States organized or supported by the Board to address this issue.
Precursor chemicals play a vital role in the processing and manufacture of illicit drugs. The Board has long been aware of their significance and works untiringly in assisting Governments to prevent diversion of these chemicals. However, in contrast to the harmful substances they are used to create, these same chemicals are extremely important in our daily lives as they provide the building blocks for innumerable commodities on which the modern world relies. The Board acknowledges the crucial function of the chemical industry in the advancement of our societies; in the same manner, it recognizes the threat chemicals pose when falling into criminal hands.
Copies for official use, in Arabic, Chinese, English, French, Russian and Spanish, are available on INCB secure portal.
The International Narcotics Control Board has repeatedly highlighted the central role of public-private partnerships and voluntary cooperation with industry as an effective strategy to address the diversion of precursors as well as the use of non-scheduled chemicals in illicit drug manufacture.
Governments of all exporting countries and territories are reminded that it is an obligation to provide pre-export notifications to Governments that have requested them pursuant to article 12, paragraph 10 (a), of the United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances of 1988.
This document contains a compilation of the recommendations relating to international precursor control produced by the International Narcotics Control Board (INCB). The recommendations have been compiled utilising the Board's annual reports on precursors from 2000-2016 and the Annual Reports from 2004-2016. As such, the document is an all-encompassing reflection of every single recommendation made by the Board in these published reports.
This directory lists competent national authorities empowered to issue certificates and authorization for the import and export of narcotic drugs and psychotropic substances; and competent national authorities empowered to regulate or enforce national controls over precursors and essential chemicals.
