The EU MRL Database: How to Look Up a Limit Before You Ship
Most residue rejections are not caused by misuse in the field. They are caused by someone assuming a limit instead of reading it — the wrong commodity line, a residue definition that includes a metabolite, or a limit that changed between the spray date and the shipping date. The database that settles all three is public and free.
Key takeaways
- EU maximum residue levels are set under Regulation (EC) No 396/2005 and published in the EU Pesticides Database.
- Where no specific limit exists, a default of 0.01 mg/kg applies. That default is effectively a prohibition for most uses.
- The residue definition, not just the active substance name, determines what the laboratory measures.
- Commodity classification matters: limits are set against specific Annex I product codes, and neighbouring crops can carry very different values.
- Limits change. Check the version in force on the date of import, and check whether an amending regulation is already adopted but not yet applicable.
How the system is built
Regulation (EC) No 396/2005 harmonised residue limits across the EU. Before it, each member state set its own, and a consignment could be legal in one country and not in the next. The regulation defines a list of products in Annex I, each with a code, and sets limits per active substance per product. If a substance and product combination has no specific limit, a default value of 0.01 mg/kg applies unless a different default is specified. For most conventional actives, 0.01 mg/kg is at or near the limit of analytical determination, which means any detectable use will fail.
Limits are not a safety line drawn at the last possible point. They are set at the highest residue expected when the product is used according to good agricultural practice, provided that level is toxicologically acceptable. That is why a limit can be tightened when a use is withdrawn even though nothing about the substance’s toxicity has changed: with no approved use, there is no expected residue to accommodate.
The legal ceiling for a residue in or on a product, expressed in mg/kg and tied to a specific commodity code.
A limit set for a use not authorised in the EU, granted on application and only where the residue is toxicologically acceptable.
What the laboratory actually measures: parent compound alone, or parent plus named metabolites, sometimes expressed as parent equivalent.
The lookup, step by step
- Fix the commodity first. Find your product in Annex I by its code, not by its common name. Table grapes and wine grapes, sweet peppers and chilli peppers, spring onions and bulb onions are separate lines with separate limits.
- Search by active substance. Enter the active, not the trade name of the formulated product. One commercial product may contain two actives, each with its own limit.
- Read the residue definition. If it includes metabolites, your own analysis must cover them. A clean parent-only result proves nothing when the definition is broader.
- Note whether the value is a default. A limit of 0.01 mg/kg usually signals that there is no approved use and no import tolerance. Treat it as a stop, not as a number to aim under.
- Check the date of application. Amending regulations typically apply some months after publication. The limit that matters is the one in force when the goods are placed on the EU market.
- Subtract the buyer’s margin. Many European retailers contract at a fraction of the legal limit, and some cap the total number of detected residues per sample regardless of individual compliance.
| Situation | What the database shows | What to do |
|---|---|---|
| Specific limit set | A value above 0.01 mg/kg for your commodity | Design the programme to the pre-harvest interval that keeps you well below it. |
| Default limit | 0.01 mg/kg with no supporting use | Do not use the active on that crop for EU export. Detection is failure. |
| Import tolerance in place | A limit set although the use is not authorised in the EU | Usable, but verify the value has not been withdrawn since your last check. |
| Limit under review | A pending application or a published but not yet applicable regulation | Plan for the new value if harvest or shipment falls after the date of application. |
| Residue definition includes metabolites | A definition naming more than the parent | Instruct the laboratory accordingly; a parent-only method is not fit for purpose. |
Analytical uncertainty cuts against you at the border. Enforcement decisions normally allow for measurement uncertainty, but a result sitting just under the limit is a result that can be reported as a breach on re-analysis. Treat the legal limit as the boundary of a zone to stay out of, not a target.
Building the habit
The useful discipline is to run the lookup at three points rather than one: when the spray programme is designed, when the crop is booked for a specific destination, and again before the consignment is dispatched. Limits change between those moments more often than people expect, particularly for actives whose EU approval is close to expiry. Keeping a dated screenshot or export of the record you relied on costs nothing and settles arguments later.

Frequently asked questions
Where is the EU Pesticides Database?
It is published by the European Commission’s Directorate-General for Health and Food Safety and covers both active substance approvals and maximum residue levels. It is the authoritative source; third-party summaries lag behind it.
What is an import tolerance?
A residue limit set for a use that is not authorised inside the EU, granted on application where the resulting residue is shown to be toxicologically acceptable. It allows produce grown with that active elsewhere to enter legally.
Do Codex limits apply in the EU?
Codex maximum residue limits are taken into account when EU limits are set, but they do not apply automatically. The value that governs an EU import is the EU value.
Does washing or processing change compliance?
Compliance is assessed on the product as presented. Processing factors exist for some commodity and substance combinations and can be applied in defined circumstances, but they are not a general allowance.
What happens if a consignment exceeds a limit?
It can be refused entry or withdrawn from the market, and the finding is normally circulated through the EU rapid alert system. Repeated findings from one origin can trigger increased checks on subsequent consignments from that country.
