What Counts as a Controlled Drug in the UK
Controlled drugs in the UK are governed by the Misuse of Drugs Act 1971 and the Misuse of Drugs Regulations 2001. The Act classifies substances into three classes — A, B, and C — based on harm and penalties. Class A includes heroin, cocaine, MDMA, and LSD. Class B includes cannabis (non-medicinal), ketamine, and certain codeine formulations. Class C covers anabolic steroids, benzodiazepines, and low-dose codeine preparations.
The Regulations divide controlled drugs into five schedules for licensing purposes:
| Schedule | Control Level | Examples | Licence Requirements |
|---|---|---|---|
| Schedule 1 | Highest control, minimal medical value | LSD, raw opium, cannabis (raw) | Licence required to possess, produce, supply, and import |
| Schedule 2 | High control, medical use | Morphine, diamorphine, methadone, amphetamines | Licence required to produce, supply, and import |
| Schedule 3 | Moderate control | Temazepam, buprenorphine, midazolam | Licence required to produce and import |
| Schedule 4 | Lower control | Most benzodiazepines, anabolic steroids | Import licence required; possession exemptions apply |
| Schedule 5 | Lowest control | Low-dose codeine preparations, pholcodine | Import licence required; some exemptions for finished medicinal products |
Schedule 1 substances face the strictest controls and are rarely licensed for commercial import outside research or specialised medical manufacturing. The schedule affects licensing requirements, storage, record-keeping, and destruction obligations.
When You Need an Import Licence
The requirement for a controlled drugs import licence is absolute: if you are importing any substance under the Misuse of Drugs Regulations 2001, you must have a valid import licence issued by the Home Office before the goods arrive in the UK. There are no de minimis thresholds or quantity exemptions for commercial imports.
The requirement applies regardless of form — raw active pharmaceutical ingredients (APIs), intermediate compounds, or finished medicinal products all require licensing if the substance is scheduled.
Limited personal use exemptions exist: individuals travelling to the UK may import up to 3 months’ supply without a licence if carrying a doctor’s letter and the medication is for personal use only. This does not extend to commercial imports, imports on behalf of others, or quantities exceeding 3 months’ supply. For more on personal licences, see the GOV.UK guidance on travelling with medicine containing controlled drugs.
For commercial operators, the critical distinction is between the domestic licence and the import/export licence. A domestic controlled drugs licence authorises activities within the UK — possession, production, or supply — but does not authorise import or export. You must hold both to lawfully bring controlled drugs into the country.
Pharmaceutical importers should note that the Home Office controlled drugs licence is separate from the MHRA Wholesale Distribution Authorisation (WDA(H)). Many operators require both. The MHRA authorisation relates to medicines regulation and good distribution practice; the Home Office licence relates to controlled drugs regulation under the Misuse of Drugs Act.

Step-by-Step Application Process
The application process for a controlled drugs import licence is managed entirely through the National Drugs Control System (NDS), an online portal operated by the Home Office Drugs Licensing and Compliance Unit (DLCU). You cannot apply for an import licence without first registering for an NDS account, and you cannot register for an NDS account without first holding a valid domestic controlled drugs licence.
Step 1: Obtain a Domestic Controlled Drugs Licence
Before accessing the NDS system, you must apply for and be granted a domestic controlled drugs licence. This authorises activities within the UK — typically possession, storage, and supply for importers. The application is made to the Home Office DLCU using the appropriate form, which varies depending on your business nature and the drug schedules you intend to handle.
Processing typically takes 4–6 weeks from receipt of a complete application. The Home Office may request additional information about premises, security arrangements, and standard operating procedures. Once granted, your domestic licence specifies the schedules you are authorised to handle and any attached conditions.
Operators should note that this is separate from EORI registration — you need both an EORI number and a controlled drugs licence to import. See our EORI number UK complete guide for registration details.
Step 2: Register for an NDS Account
With a valid domestic licence, register for an NDS account at dflu.homeoffice.gov.uk. Registration requires your domestic licence number, business details, and information about individuals authorised to use the NDS system on your behalf.
NDS account processing takes approximately 5 working days. During this period, the DLCU verifies your domestic licence details and sets up trading partner and preparation registrations. You receive login credentials once active.
Step 3: Register Trading Partners and Preparations
Before applying for an import licence, register trading partners and preparations in the NDS system. A trading partner is the overseas entity supplying the controlled drugs. A preparation is the specific formulation or product you intend to import.
Trading partner registration takes 5 working days. Provide the supplier’s full legal name and address, plus relevant licensing details from their jurisdiction. The DLCU may verify these with the exporting country’s competent authority.
Preparation registration also takes 5 working days. Specify the controlled drug substance, schedule, formulation, and strength. For finished medicinal products, provide the product name and marketing authorisation details where applicable.
Step 4: Apply for the Import Licence
Once trading partners and preparations are registered, apply for an import licence through the NDS portal. The application requires you to specify the preparation(s), trading partner(s), quantity (in grams or millilitres for the pure base substance), expected shipment date, and port of entry.
For internationally controlled substances under UN drug conventions, the NDS system references International Narcotics Control Board (INCB) estimates and assessments. If your intended import would exceed the UK’s INCB assessment, your application may be delayed or refused.
For export licence applications, you must also provide a copy of the import permit or equivalent authorisation from the destination country. The UK will not issue an export licence without evidence that the receiving country has authorised the import.
Licence Types, Validity, and Conditions
Controlled drugs import licences are issued for specific shipments and are subject to strict conditions. Understanding the validity periods and conditions attached to your licence is essential to avoid compliance breaches that could result in criminal penalties.
Validity Periods
Import licences are valid for 3 months from the date of issue. This means the shipment must arrive in the UK within 3 months of the licence being issued. If the shipment does not arrive within this period, the licence expires and a new application must be submitted.
Export licences are valid for 2 months from the date of issue, or for the duration of the importing country’s permit if that is shorter. The shorter validity period for exports reflects the need to coordinate with the importing country’s authorisation timeline.
Single-Use Per Shipment
Each import licence is single-use. Once a shipment has been made against the licence, the licence is exhausted and cannot be used again. This applies even if you ship less than the licensed quantity — the licence cannot be used for a second shipment of the balance.
If you need to import the same preparation from the same trading partner on multiple occasions, you must submit a separate licence application for each shipment. There is no provision for multiple-entry import licences for controlled drugs.
Under-Shipment and Endorsement
The NDS system requires endorsement of the actual quantity shipped immediately after dispatch — not after arrival. Log into the NDS portal, select the relevant licence, and enter the actual quantity shipped.
If you under-ship (ship less than the licensed quantity), the licence is still exhausted. You cannot use the remaining balance for a subsequent shipment. This is a common point of confusion for new importers, who sometimes assume a licence covers a quantity that can be shipped in multiple consignments. It does not.
No Post-Dating or Retrospective Issuance
Import licences cannot be post-dated or issued retrospectively. The licence must be in place before the goods are shipped from the overseas supplier. If goods arrive in the UK without a valid import licence, they will be detained by Border Force and may be subject to seizure and destruction.
Similarly, you cannot amend a licence after it has been issued to change the shipment date, quantity, or trading partner. If any of these details change, you must submit a new licence application.
For operators who frequently import medicines in finished dose form (Schedules 2–4 only), there is a frequent exporter licence available for those making 24 or more shipments per year. This is not available for importers, and it does not apply to Schedule 1 substances.
Exporting Controlled Drugs
While this guide focuses on imports, many operators also export controlled drugs from the UK. The licensing requirements for exports mirror those for imports, with some additional considerations.
Export Licence Requirements
An export licence is required for all controlled drugs exported from the UK, regardless of destination. The application process is the same as for imports — via the NDS system — but with one additional requirement: you must provide a copy of the import permit or equivalent authorisation from the destination country.
The UK will not issue an export licence without evidence that the receiving country has authorised the import. This is a requirement under the UN drug conventions and is strictly enforced by the DLCU.
Channel Islands and Postal Services
The Channel Islands (Jersey and Guernsey) operate separate licensing regimes from the UK. Exports to Jersey and Guernsey require an export licence, and the importer must hold a valid licence from the relevant Channel Islands authority. The frequent exporter licence (for 24+ shipments per year) is available for exports of medicines in finished dose form (Schedules 2–4 only) to the Channel Islands.
Controlled drugs cannot be posted from overseas for personal use. They must be imported through a registered pharmaceutical wholesaler holding the appropriate licences. This is a common point of confusion for individuals seeking to import medication from overseas pharmacies — such imports are not lawful without the proper licensing arrangements in place.
Penalties for Non-Compliance
The penalties for importing or exporting controlled drugs without a licence are severe. Under the Customs and Excise Management Act 1979 (CEMA) Schedule 1, importing or exporting a controlled drug without a licence is a criminal offence.
The maximum penalties depend on the class of drug involved:
| Class | Maximum Penalty on Indictment |
|---|---|
| Class A | 14 years imprisonment or life (for production/supply) |
| Class B | 14 years imprisonment |
| Class C | 14 years imprisonment (increased from 2 years in 2003) |
In practice, sentences for commercial import offences involving significant quantities of controlled drugs frequently result in custodial sentences. The Sentencing Council guidelines for drug offences take into account the harm category (based on the drug type and quantity) and the culpability of the offender (based on their role in the operation).
Beyond criminal penalties, non-compliance can result in seizure and destruction of goods, revocation of existing licences, disqualification from holding future licences, reputational damage, and MHRA enforcement action for pharmaceutical operators.
For context on HMRC enforcement powers more broadly, see HMRC customs powers and penalties.

Frequently Asked Questions
How long does it take to get a controlled drugs import licence?
NDS account registration takes 5 working days. Trading partner and preparation registration each take around 5 working days. Licence applications are typically processed within 5–10 working days, though this varies depending on the substance and whether INCB assessments need verification. Plan for 3–4 weeks minimum from starting the process to receiving your first import licence.
Can I import controlled drugs without a domestic licence?
No. You must hold a valid domestic controlled drugs licence before you can register for an NDS account, and you cannot apply for an import licence without an NDS account. The domestic licence is the foundation of the entire licensing regime.
What happens if my shipment arrives after the licence expires?
The licence is valid for 3 months from the date of issue. If the shipment arrives after this period, the licence has expired and the import is not covered. The goods may be detained by Border Force and could be subject to seizure. Always ensure your shipment timeline allows for the licence validity period.
Can I change the quantity or shipment date on an existing licence?
No. Import licences cannot be amended after issuance. If the quantity or shipment date changes, you must submit a new licence application. This is a common source of compliance breaches — operators sometimes assume minor changes are permissible. They are not.
Do I need a licence for Schedule 5 controlled drugs?
Yes. All scheduled controlled drugs require an import licence, regardless of the schedule. However, some Schedule 5 preparations (particularly low-dose codeine products in finished medicinal form) may qualify for certain exemptions under the regulations. Seek specific advice from the DLCU if you are importing Schedule 5 substances.
What records must I keep after importing controlled drugs?
Licensees must keep detailed records of all imports, including copies of licences, shipping documents, and NDS endorsements. Annual statistical returns must be submitted to the Home Office for wholesalers, manufacturers, producers, and suppliers. Record-keeping requirements are set out in the Misuse of Drugs Regulations 2001 and in your licence conditions.
