Overview
The effective control of chemicals used in the illicit manufacture of narcotic drugs and psychotropic substances is an important tool in combating drug trafficking. These chemicals, known as drug precursors, also have legitimate commercial uses as they are legally used in a wide variety of industrial processes and consumer products, such as medicines, flavourings and fragrances.
It is necessary to recognise and protect the legal trade in these substances, while at the same time discouraging their diversion for illicit purposes. Drug precursor chemicals should not be confused with Explosive precursor chemicals which are controlled under a separate regime.
Categories
Regulation of drug precursors covers a number of chemical substances which are divided into 4 categories:
- category 1 covers the most sensitive substances (the main drug precursors)
- category 2 covers less sensitive substances and some pre-precursors
- category 3 covers bulk chemicals that can have different types of uses in the manufacturing process (for example, as feedstock, solvents or impurities removers)
- category 4 covers medicinal products of some category 1 substances
With the exception of category 4 drug precursor chemicals, the legislation generally excludes medicinal products for human use, but covers all natural products and preparations (or mixtures) containing at least one scheduled substance, provided that they can be extracted by readily applicable or economically viable means.
The list of precursors and chemicals frequently used in the illicit manufacture of narcotic drugs and psychotropic substances under control are defined by the United Nations International Control Board.

Legal background
The basis for precursor control is to be found in the United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances adopted in Vienna on 19 December 1988.
UN convention
Article 12 of the convention specifically covers substances frequently used in the illicit manufacture of narcotic drugs and psychotropic substances and requires that countries implement measures to control and monitor the legitimate trade in drug precursors as an essential way to prevent their diversion.
Legislation
The convention is implemented through the following legislation:
- Feb 2004 Regulation (EC) No 273/2004, which controls and monitors intra-community trade as amended by The Law Enforcement and Security (Amendment) (EU Exit) Regulations 2019
- Dec 2004 Regulation (EC) No 111/2005 on trade between EU and third countries as amended by The Law Enforcement and Security (Amendment) (EU Exit) Regulations 2019
- Article 5(4) Protocol on Ireland/ Northern Ireland
Definitions
The terms used in this guidance are defined as:
Placing on the market: any supply, whether in return for payment or free of charge, of scheduled substances; or the storage, manufacture, production, processing, trade, distribution or brokering of these substances for the purpose of supply.
Operator: any natural or legal person engaged in the placing on the market of scheduled substances.
Responsible officer: operators are required to appoint an officer responsible for the trade in scheduled substances. The officer shall be empowered to represent the operator and to ensure that the trade conducted takes place in compliance of regulations.
Guarantor: another senior person in the company that agrees to guarantee the responsible officers performance of their obligations.
Domestic licensing
Domestic licences are required for any companies that possess, manufacture, produce or supply drugs precursor chemicals in England, Wales or Scotland. Domestic licensing requirements apply to Category 1, 2 and 3 drug precursor chemicals.
Domestic licensing requirements for operators in precursors can be found on the Precursor chemicals wallchart for domestic licensing.
You must hold a valid domestic licence to be able to apply for an import-export licence.
