Cracking Down on Chemicals Used to Make Illegal Drugs

Published December 03, 2025

Goal: Stop illegal drugs

This new EU regulation merges old rules, creates a digital system to license and track dangerous chemicals, bans designer precursors unless licensed, and cuts paperwork for businesses.

What the problem that is being addressed

  • Illicit drug makers are increasingly using designer precursors – chemicals that have no normal commercial use but can be turned into drugs.
  • The two existing EU rules (Regulation (EC) No 273/2004 for the internal market and Regulation (EC) No 111/2005 for trade with third countries) are old, split, and create a lot of paperwork for businesses that sell or use these chemicals.
  • The rules do not cover designer precursors well, and the administrative burden on operators and customs authorities is high.

How that problem is being solved here

  • The two old regulations are merged into one new Regulation that covers both internal and external trade.
  • Three new categories of precursors are defined:
  1. Category 1 – the most dangerous chemicals (e.g., phenylacetone).
  2. Category 2 – widely used chemicals that can still be diverted (e.g., red phosphorus, hydrochloric acid).
  3. Category 3 – designer precursors that have no normal use except research.
  • Designer precursors are now automatically banned unless a company gets a licence or gives a prior notification for research use.
  • A centralised electronic system will let operators:
  • apply for licences, registrations and prior notifications online.
  • verify that their customers also have licences.
  • report suspicious transactions, thefts or disappearances.
  • notify customs of import/export quantities.
  • Customs will use the same system to check licences and quantities before releasing goods.
  • A Drug Precursors Information Repository will list all scheduled and non‑scheduled substances, their legitimate uses and how they can be used in drug production.
  • The new rules remove the need for periodic reporting by operators and simplify many administrative steps.

What changes as a result of this document

Item Change Numbers
Licences & registrations Simplified, digital, fewer forms 10 % rise in enforcement costs; one‑off cost of €7.7 million for operators to adjust to new rules
Administrative burden Reduced by €25.27 million per year (net saving) 25.27 million €
Digital system Built by DG GROW, linked to the EU Single Window for customs €1.322 million (internal market IT) + €24.148 million (external trade IT)
Information repository New database of all precursors €0.530 million
Transition period 3 years after entry into force for full application 3 years
Review 10‑year evaluation of the Regulation 10‑year review
SME impact 92 % of the ~4 000 active licences are SMEs 4 000 licences, 92 % SMEs
Budget Total estimated cost for IT and repository over 2028‑2034 €26.427 million (IT) + €0.530 million (repo) + €24.148 million (external trade) ≈ €51 million
Legal Repeals Regulations (EC) No 273/2004 and (EC) No 111/2005
Scope Covers all scheduled and non‑scheduled precursors, except for pharmacies, veterinary dispensaries and certain official authorities

The Regulation therefore tightens control of dangerous chemicals, speeds up customs checks, cuts paperwork for businesses, and creates a single digital platform that will make the EU’s drug‑precursor system clearer and more efficient.
