Precursor chemicals and clandestine laboratories in Europe

Precursors are ordinary industrial chemicals with lawful uses, controlled across the European Union by regulations imposing licensing, registration and the reporting of suspicious orders. Possession is not the offence. What is punished is handling them while knowing, or accepting, that they are destined for illicit production, which is why these files turn on knowledge rather than on chemistry.
That shapes who is exposed and what can be done about it. A distributor, a logistics operator or an equipment supplier is drawn in alongside the people running a site, and the company itself faces proceedings judged on whether its controls existed and worked. The defence is largely documentary: licences, customer declarations, checks on buyers and reporting records already sit in the company's systems, and they are what separates a lawful sale from a knowing supply.
Avv. Massimo Romano — Ordine degli Avvocati di Napoli n. 14553, patrocinante in Cassazione dal 23/10/2015 — Roma, Via Avicenna 97, 00146 · Milano, Via Giuseppe Pecchio 3, 20129 · Napoli, Corso Umberto I 237, 80138 — +39 335 669 3954
In brief
- Control operates through categories of scheduled substances carrying different obligations, with licensing or registration required of operators according to the category concerned.
- Reporting a suspicious order is an obligation in itself, and failing to report is sanctioned separately from any involvement in production.
- The market moves ahead of the schedules, so producers turn to closely related chemicals not yet listed, and prosecutions then rest on the general provisions and on proof of destination.
- Equipment is covered separately: glassware, reactors and tabletting machines are treated as apparatus for production rather than as ordinary stock in trade.
- Knowledge of destination is the battleground, and the contrast is stark between a listed substance sold to a registered buyer for a stated purpose and a delivery arranged to a farmhouse at night.
- Attribution at a site has to be proved rather than assumed, since presence where equipment is found is not production, and who rented, who paid and whose traces are present all have to be established.
- The stage reached matters, because preparation, attempt and completed production are different offences, and what was actually achievable with the material present is a technical question.
- Whether a seized substance was a precursor, an intermediate or inert is a laboratory matter, and the defence is entitled to test the analysis rather than accept the report as it stands.
How the control works
| Element | Content | Note |
|---|---|---|
| Scheduled substances | Categories with different obligations | EU regulations on drug precursors |
| Licensing and registration | Required for operators handling them | Depending on the category |
| Reporting of suspicious orders | An obligation on the operator | Failure is itself sanctioned |
| Non-scheduled chemicals | Watch lists and voluntary cooperation | Designer precursors move faster than the lists |
| The offence | Handling for illicit production | Knowledge or acceptance of destination |
| Equipment | Apparatus for production is separately covered | Glassware, reactors, tabletting machines |
The gap between the schedules and the market is the recurring problem. Producers move to chemicals not yet listed — closely related substances that convert in one step — and prosecutions then rely on the general provisions and on proof of destination rather than on a schedule entry.
What the defence works on
- Knowledge of destination. A chemical supplier who sold a listed substance to a registered buyer for a stated purpose is in a different position from one who arranged delivery to a farmhouse at night.
- The paperwork. Licences, customer declarations, know-your-customer checks and reporting records are the defence, and they exist in the company's systems.
- Attribution at the site. Presence at premises where equipment is found is not production, and who rented, who paid and whose traces are present have to be established.
- The stage reached. Preparation, attempt and completed production are different offences, and the analysis of what was actually achievable with what was there is technical.
- Expert evidence. Whether a mixture was a precursor, an intermediate or an inert substance is a laboratory question, and the defence is entitled to test it.
Where a business is involved
Chemical distributors, logistics companies and equipment suppliers are drawn into these cases regularly, and the exposure is not only individual: the entity itself faces proceedings, judged on whether its controls existed and worked. The framework is in the guide on corporate criminal liability.
The recurring failure is documentary. A company that cannot show what checks it ran on an order is left arguing about intention with nothing to argue from.
The same consignment can be a routine sale or a knowing supply, and the difference is read from the transaction itself. The table sets out which features point each way.
| Element of the transaction | Points towards a lawful sale | Points towards a knowing supply |
|---|---|---|
| The buyer | A registered operator with a licence on file | An individual with no trade in the substance |
| The stated purpose | A use consistent with the buyer's business | A purpose never explained, or plainly implausible |
| Delivery | To business premises, against signed documents | To a private address or a rural site, outside working hours |
| Payment | Through the company's ordinary banking channels | Cash, or through a party unconnected with the buyer |
| Volume and pattern of orders | Consistent with the buyer's normal consumption | Quantities and frequency that fit no declared activity |
| The file kept on the customer | Checks and declarations retained and dated | No file, or a file assembled after the enquiry began |
Frequently asked questions
Is possessing a precursor an offence?
Not in itself: they are lawful chemicals under a control regime. The offence is handling them knowing, or accepting, that they are destined for illicit production.
What if the chemical is not on any list?
Prosecutions then rely on general provisions and on proof of destination. Designer precursors move faster than the schedules, and that is the ordinary situation.
Our company supplied a listed substance.
Licences, customer declarations, checks and reporting records are the defence, and the entity itself can be prosecuted on whether its controls existed and worked.
I was present where equipment was found.
Presence is not production. Who rented, who paid, whose traces are present and what was actually achievable all have to be established.

What an investigation does to a business and a household
When a precursor case begins, the effect on daily life is out of proportion to the chemistry. The people involved are usually ordinary operators: a small trader, a logistics company, a laboratory supplier, an online seller or an employee who processed an order. They did not think of themselves as part of anything illicit, and then a search team arrives at the premises, takes computers, order books and stock, and leaves a company unable to ship or invoice for days.
Money suffers earliest. Bank accounts may be examined or restricted, stock may be seized, and customers who hear about the investigation stop paying or stop ordering. A supplier who relied on a single buyer for most of its turnover can find itself in difficulty within weeks. Insurers may refuse cover, and lenders may call in facilities. Licences held for handling regulated chemicals can be put at risk even before any finding, because the authorities that issue them are told.
The personal side is just as sharp. A director or sales manager may be told not to leave the country, may have a passport retained, or may be asked to attend repeated interviews. Employees fear for their jobs and are tempted to talk among themselves, which is dangerous. Families see the premises sealed and hear the word laboratory in the same sentence as the person's name, and the reputational harm spreads quickly in a small trade community.
Plan for this broader fallout. List the contracts, deliveries and licences that depend on normal operation, and tell the lawyer which of them are most exposed. Several of these problems can be addressed through applications to restore access to documents or stock, but only if they are raised promptly.
Who comes to this page
A reader runs a small business that sells industrial chemicals and has just had a search. The officers asked about particular customers and particular orders, took the order records, and left a document the owner cannot fully read. The owner is sure no offence was intended, because every sale looked routine, and wants to know what the authorities think the business knew and when.
Another reader is an employee, perhaps in sales, purchasing or shipping, who was asked to attend as a witness and now suspects the status may change. They processed orders as part of their job and are anxious about being held responsible for decisions that their employer made. They want to know whether to speak, whether to take their own lawyer and whether the company's lawyer can act for them.
Another reader is a relative or partner of someone arrested after a clandestine laboratory was found. The person may have rented a unit, bought equipment or lent a vehicle, and the family is trying to understand how a series of ordinary acts came to be treated as participation. They want to know what the charge says, how long the matter may last and what to do about the property that was seized.
All of these readers face the same core issue: the offence does not turn on possessing the chemical. It turns on knowledge, or acceptance, of where it was going. That makes the file a story about what people knew, which is why careful handling of statements and documents matters so much in the early days.
These cases are answered with paper that already exists somewhere in the business. The table lists the documents, who keeps them and what each is used to prove.
| Document | Who holds it | What it is used to prove |
|---|---|---|
| The licence or registration for the category | The authority that issued it | That the operator was entitled to handle the substance |
| Customer declarations of intended use | The customer, with a copy kept by the operator | What the buyer stated the material was for |
| Checks carried out on the buyer | The operator's compliance records | That the sale was examined before it went through |
| Reports of suspicious orders | The operator and the authority receiving them | That the reporting obligation was met when it arose |
| Transport and delivery documents | The carrier and the warehouse | Where the material actually went, and who signed for it |
| Laboratory analyses in the file | The investigating authority | What the seized substance was, and whether the method is sound |
What to gather before anything else
These cases are won or lost on documents that show what the operator knew and did at the time of each order. Assemble the following before the initial conversation with a lawyer, and send copies rather than originals.
- Everything handed over at the search, photographed in full: the order authorising it, the list of items seized and any record the officers asked you to sign.
- Licences, registrations and permits that the business holds for handling controlled chemicals, with dates and the offices that issued them.
- Customer checks: forms, declarations of end use, identity checks and any questionnaires sent before a sale. They show what the business asked and how it responded to the answers.
- The orders themselves, with quantities, dates, destinations and payment details, plus delivery records and transport documents.
- Records of any report of a suspicious order made to an authority, and any internal note explaining why an order was accepted or refused.
- Staff lists showing who handled each stage, so responsibility can be assigned accurately.
- Internal procedures and training records on handling controlled chemicals and spotting unusual requests.
- Correspondence with customers, including emails and messages, preserved exactly as they are.
- The names of advisers, such as compliance consultants or accountants, who may hold relevant material.
The decisions of the coming days
A precursor investigation poses a handful of real choices, and each has a price. The most urgent is whether people connected with the business should speak to investigators before they have taken advice. Because the case turns on knowledge, a careless remark about a customer, such as an offhand comment that an order looked odd, can be treated as proof that the operator suspected something. An account given without documents in front of you can also be inaccurate in detail. The price of waiting is that investigators may read hesitation as evasion, but a considered statement made with counsel and records is worth far more than a hurried statement.
The next choice is whether the company and the individuals need separate lawyers. Their interests can diverge: the business may want to show that the director was misled, while the director may want to show that the system was sound. Sharing counsel is cheaper, but it can compromise both. The decision should be taken early, before anybody gives a statement that fixes a position.
A further choice is how to treat the seized material. The business may need copies of documents to keep operating or to answer customers and regulators. Asking for them is sensible, but the request must be made through counsel and should not be accompanied by commentary on the facts.
Finally, decide how to speak to customers, suppliers, banks and the authority that issued the licences. Silence can alarm them, and an explanation can be used against you. Agree a short, neutral message and a single person who delivers it.
Mistakes to avoid
Under pressure, businesses and individuals make the same errors, and several of them are expensive. Avoid the following.
- Do not discuss customers or orders with colleagues in ways that could look like agreeing an account. Conversations and messages can be examined.
- Do not alter, tidy or backdate records. Changing an order form or adding a note after the event is treated as concealment and destroys the credibility of everything else.
- Do not delete emails or messages with customers. They are often the best proof that the operator asked the right questions.
- Do not contact the customer under investigation to ask what they told the authorities.
- Do not sign a record of search or interview that you cannot read in full.
- Do not make public statements on social media, in trade forums or to the press.
- Do not assume that a lawful sale is a defence by itself. The question is what was known or accepted about the destination.
- Do not let any employee speak for the company without agreement on what will be said.
Exposure runs on separate tracks for the person and for the business, and they are defended differently. The table compares them.
| Feature | The individual | The company |
|---|---|---|
| What is alleged | Handling material with knowledge of its destination | A failure of the controls that should have prevented it |
| What the proceedings examine | Conduct and state of mind | Whether a control model existed and was actually applied |
| Who answers | The person who arranged or carried out the supply | The entity, through its representatives |
| What the defence rests on | The transaction documents and the absence of knowledge | Evidence that procedures existed, were trained and were enforced |
| What is at stake beyond the penalty | Personal liability and restrictions on activity | Licences, contracts and the ability to keep trading |
| What has to be preserved at once | Correspondence and the customer file | Compliance records, training logs and reporting history |
Questions to ask your lawyer
Because these cases turn on knowledge, the useful questions are about proof of what people knew. Bring these to the lawyer.
- What exactly does the file say I or the business knew or accepted, and what evidence does it rely on?
- Which substances are involved, how are they classified, and what obligations applied to each?
- Did the business hold the right licences and registrations at the time of each order?
- Were there warning signs in the orders, and how will the other side say we should have reacted?
- What did our checks on customers show, and how can we prove them?
- Do the company and the individuals need separate lawyers, and when must that be decided?
- What can be done to recover documents, stock or accounts that were seized or restricted?
- What does the investigation mean for our licences, and who must be told?
- If the matter crosses a border, who coordinates with the lawyer abroad?
When the chemicals, the customers or the laboratory are abroad
Precursor cases are inherently international. A chemical may be produced in a country, shipped through a neighbour and delivered to a customer further away, and the clandestine laboratory may sit somewhere else again. The control regime is European, but enforcement, language and procedure are national, so a single order can generate parallel inquiries that do not coordinate quickly.
Documents are the usual bottleneck. Invoices, certificates and customs papers from other countries may need official translation and certification before an Italian authority will use them, and Italian records requested abroad face the same route. Start immediately, scan everything and keep a log of what was sent and to whom. Post is slow and a missing certificate can delay a hearing.
Calls across time zones should be scheduled in advance, since offices in different countries keep different hours and holidays. Agree who contacts the lawyer abroad and who reports to the business. Where a foreign authority has also requested information, the lawyers must coordinate so that what is said in any inquiry does not contradict the others.
If an individual is detained abroad in connection with a precursor matter, the consulate can confirm where they are and pass messages, but it does not choose the lawyer, pay for the defence or address the merits. Tell the office from the outset which countries are involved, in which languages the records are kept, and whether any foreign proceeding exists.
Terms you will meet in these files
These words appear on this page and are likely to appear on documents connected with a precursor case. Understanding them lowers the anxiety of reading a file.
- Precursor is an ordinary industrial chemical with lawful uses that can also be used in illicit production. The substance is not unlawful in itself.
- Scheduled substances are the categories of precursor that carry obligations, with different duties depending on the category.
- Licensing and registration are the permissions that operators handling scheduled substances must hold, depending on the category.
- Suspicious order is a request that raises concern about its end use. Operators have an obligation to report it, and failure to do so is sanctioned in itself.
- Non-scheduled chemicals are substances not on the controlled lists, for which watch lists and voluntary cooperation apply.
- Knowledge is the legal heart of the offence: knowing, or accepting, that the chemical is destined for illicit production.
- Clandestine laboratory is a site used for illicit production, which is where precursors are often found.
If another term appears on a document, ask the lawyer to explain it before anyone responds.
How the office handles precursor investigations
Contact is by phone on +39 335 669 3954 or by email at avvmassimoromano@gmail.com. A call about a search, an arrest or a seizure is treated as urgent, including outside normal hours. The initial conversation covers what happened, what papers were handed over, who is affected and whether anybody is detained.
The office works in English and Italian. Photographs of documents can be sent through a secure channel and are read before any approach is suggested. For a business the plan usually distinguishes the position of the company from that of each individual, sets out who should and should not speak to investigators, and lists the documents that must be gathered and preserved.
Where the case touches another country, the office identifies a lawyer qualified there, agrees the scope of that work and coordinates, so that statements, applications and messages are consistent. Updates reach the client through a single point of contact after each development.
The engagement is confirmed in writing, with scope and fees stated clearly. The firm has offices in Rome at Via Avicenna 97, in Milan at Via Giuseppe Pecchio 3 and in Naples at Corso Umberto I 237, and meetings can be held in person or by video. No outcome is promised, but you will know what is being done and why.
About the lawyer
A relative detained abroad changes the shape of a family's day: nobody knows who to call first, and the information that does arrive is fragmentary. Avv. Massimo Romano works on Italian criminal matters, European arrest warrants and the position of Italians arrested outside Italy, and he is admitted to plead before the Court of Cassation. The office works from Rome, Milan and Naples, which matters when papers have to be filed in one city while the family lives in another. Contact usually begins with a telephone call or a WhatsApp message describing, in plain terms, what happened. He reads whatever paperwork exists before giving an opinion; if something is missing, he says what to ask for and who to ask. After that first conversation the family receives a written account of the position and the steps that follow. Discussions with relatives are held in the language they use at home.
Telephone the office or send a WhatsApp message. Before you call, gather the document you received, the name of the authority written on it, and the file reference if one appears.
