Precursor chemicals are ordinary industrial and pharmaceutical substances that can also be used to make illegal drugs. Acetone is a common solvent; pseudoephedrine is in cold medicines; acetic anhydride is used in manufacturing. Because the same chemicals feed illicit laboratories, Kenya treats their misuse as one of the most serious drug offences on its statute book. Any manufacturer, importer, distributor or pharmacy that handles precursor chemicals in Kenya needs to know which substances are listed, what conduct is criminal, and how to protect itself from being used as a supplier. This guide explains the framework.
Which Chemicals Are Listed
The Narcotic Drugs and Psychotropic Substances (Control) Act (Cap. 245) lists precursor chemicals in its Fourth Schedule, inserted by the Narcotic Drugs and Psychotropic Substances (Control) (Amendment) Act, 2022. The Schedule, as consolidated on Kenya Law, names:
- ephedrine and pseudoephedrine;
- ergometrine, ergotamine and lysergic acid;
- 1-phenyl-2-propanone;
- acetic anhydride, acetone, anthranilic acid, ethyl ether, phenylacetic acid and piperidine;
- the salts of those substances wherever such salts can exist.
The list mixes medicines with bulk industrial chemicals. A pharmaceutical wholesaler selling pseudoephedrine products and a chemical trader selling drums of acetone are both dealing in Fourth Schedule substances.
What the Offence Covers
Section 4A of the Act creates the offence. A person commits it if they:
- manufacture or possess a Fourth Schedule substance for the purpose of producing any narcotic drug or psychotropic substance; or
- transport or supply such a substance to another person, knowing or having reasonable grounds to suspect that it is to be used in, or for, the unlawful production of a narcotic drug.
The penalty on conviction is a fine of not less than fifty million shillings and imprisonment for not less than twenty years. These are mandatory minimums, and the fine and imprisonment are cumulative rather than alternatives.
Two features matter most for legitimate businesses. First, the offence is not about possessing the chemical as such. Selling acetone to a paint factory is lawful. Second, the supply limb is triggered by “reasonable grounds to suspect”, not only by actual knowledge. A supplier that ignores obvious warning signs cannot rely on saying it did not know what the buyer intended.
Who Is Exposed
The businesses most exposed are those that sell listed chemicals to many small customers: chemical distributors, laboratory suppliers, hardware and industrial traders, and pharmaceutical wholesalers and pharmacies handling ephedrine or pseudoephedrine products. Transporters and warehouse operators can also fall within the supply and transport limb if they move consignments in suspicious circumstances. Directors should assume that a prosecution of the company will look closely at what the board knew and what controls it had approved.
Regulations and Record-Keeping
Section 4A(2) allows the Cabinet Secretary responsible for internal security to make regulations to carry out the section, in particular on documenting transactions in Fourth Schedule substances, adding or removing substances from the Schedule, and keeping records and furnishing information. Businesses should check whether any such regulations are in force before relying on general practice, and should monitor any changes to the Schedule.
Even without detailed regulations, good records are the strongest defence a supplier has. A record showing who bought the chemical, in what quantity, for what stated use, and what checks were made, is the evidence that the supplier had no reasonable grounds for suspicion.
Imports and International Controls
Precursor trade is also controlled internationally under the 1988 United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. Exporting countries use the International Narcotics Control Board’s PEN Online pre-export notification system to tell importing countries’ authorities about planned shipments of listed chemicals. A Kenyan importer should therefore expect its foreign supplier to need regulatory clearance, and should not be surprised if shipments are queried or delayed.
Where the precursor is itself a medicine, such as a pseudoephedrine product, the ordinary pharmaceutical rules also apply. The product must be registered under the Pharmacy and Poisons (Registration of Health Products and Technologies) Rules, 2022, and the distributor needs a wholesale licence under section 27 of the Pharmacy and Poisons Act (Cap. 244). Our guide to obtaining a pharmaceutical wholesale licence in Kenya explains that licence.
Practical Controls for Suppliers
- Know your customer. Verify the buyer’s identity, business registration, premises and the stated end use before first supply.
- Check plausibility. Compare order quantities with what the customer’s business could realistically use.
- Watch for warning signs. Cash payments, third-party payers, unusual delivery addresses, reluctance to explain end use and sudden large orders all call for questions.
- Record everything. Keep transaction records, customer files and notes of any refused orders.
- Escalate. Have a clear route for staff to raise concerns, and take legal advice promptly when a transaction looks wrong.

Frequently asked questions
Is it illegal to sell acetone in Kenya?
No. Acetone is a listed precursor, but the offence under section 4A applies to possession for drug production, or supply where the supplier knows or has reasonable grounds to suspect the chemical will be used for unlawful drug production.
What is the penalty for a precursor offence?
A fine of not less than fifty million shillings and imprisonment for not less than twenty years.
Are pseudoephedrine medicines precursors?
Yes. Pseudoephedrine and its salts are in the Fourth Schedule. Products containing it are also medicines subject to registration and wholesale licensing under the Pharmacy and Poisons Act.
Can the list of precursors change?
Yes. Section 4A(2) allows the Cabinet Secretary responsible for internal security to add or remove substances by regulation.
