In March 2026, a company in Mulhouse that manufactures transmission parts for industry, with one hundred and eighty employees and half its turnover from exports, receives a letter from its main Japanese customer. The customer is reorganising its supply chain and asks all its European suppliers to show, by the end of the year, that they hold Authorised Economic Operator (AEO) status. The administrative and finance director opens the self-assessment questionnaire, reads it to the end and stops at one question: has the company committed any infringements of customs legislation in the last three years? In 2024, it entered into a customs settlement (transaction) over a valuation error. The amount was modest. The question, much less so.
AEO status is often presented as a label obtained by filling in a file. It is an administrative decision, based on precise criteria, preceded by an on-site audit and followed by ongoing monitoring. This page explains what the status really brings, what it requires, how the procedure works, and how to prepare for it without turning the application into the starting point of an inspection.
1. Two statuses, one logic
Any economic operator established in the customs territory of the Union that meets the criteria of Article 39 may apply for Authorised Economic Operator status (Art. 38(1) of the Union Customs Code (Regulation (EU) No 952/2013)). The status consists of two types of authorisation: AEO for customs simplifications, known as AEOC, which allows the holder to benefit from certain simplifications under customs legislation; and AEO for security and safety, known as AEOS, which gives entitlement to facilitations relating to security (Art. 38(2)). The same person may hold both at the same time (Art. 38(3)), in which case the authority issues a combined authorisation (Art. 33 of Implementing Regulation (EU) 2015/2447).
The status is recognised by the customs authorities of all Member States (Art. 38(4)). It may also have effects outside the Union. The benefits of the status are granted to operators established in third countries whose conditions are recognised as equivalent, on a reciprocal basis and under an international agreement or Union legislation (Art. 38(7)). It is this mutual recognition mechanism that explains the Japanese customer’s request: its own authorised operator status presupposes a supply chain made up of reliable operators.
Which one to choose? It depends on the business. An importer or exporter wishing to access clearance simplifications will aim for AEOC. A company that forms part of an international logistics chain, or whose customers require it for security reasons, will aim for AEOS. In most cases, a combined application makes the most sense, because the audit covers largely common criteria and the additional criterion for each (competence for one, security for the other) adds little to the overall effort.
2. What the status really brings
The Union Customs Code promises the authorised operator more favourable treatment than other operators in respect of customs controls, including fewer physical and document-based controls (Art. 38(6)). Delegated Regulation (EU) 2015/2446 sets out what this involves (Art. 24). When the AEO lodges certain declarations, it is notified in advance that its consignment has been selected for control, before the goods arrive or before they are presented to customs, unless notification might jeopardise the control. Its selected consignments are given priority for control and, at its request, may be controlled at a place other than the place where the goods must be presented.
There is one limit, however. This favourable treatment does not apply to controls related to specific elevated threat levels or to control obligations laid down in other Union legislation (Art. 25 of the Delegated Regulation). Sanitary, phytosanitary or dual-use controls, for example, continue to apply under their own rules.
The second benefit is less visible. It often matters more. On the basis of AEOC status, and provided that the requirements specific to each simplification are met, the authorities authorise the operator to benefit from the simplifications provided for under customs legislation, without re-examining the criteria already verified when the status was granted (Art. 38(5)). The status then works like a passport: it shortens the examination of all subsequent authorisations.
Our position is measured, and it contrasts with some promotional discourse. For a company that makes only a few dozen declarations a year, reduced controls do not in themselves justify the investment the status represents. The real reason for an application almost always lies elsewhere: access to simplifications, a customer’s requirement, or the wish finally to structure the customs function within the company. Without one of these reasons, it is better to refrain.
3. The five criteria, as the administration reads them
Article 39 of the Union Customs Code sets out the criteria for granting the status, and Implementing Regulation 2015/2447 specifies how they are assessed.
The first criterion is the absence of any serious infringement or repeated infringements of customs legislation and taxation rules, including no record of serious criminal offences relating to the economic activity (Art. 39(a)). For a company, it is assessed over the previous three years and covers not only the applicant but also the person in charge of the company or exercising control over its management, and the employee in charge of customs matters (Art. 24(1) of the Implementing Regulation). The text allows significant flexibility: the criterion may be considered fulfilled where the authority considers an infringement to be of minor importance in relation to the number or size of the operations, and has no doubts as to the applicant’s good faith (Art. 24(2)).
The second criterion is the demonstration of a high level of control of operations and of the flow of goods, by means of a system of managing commercial records and, where appropriate, transport records (Art. 39(b)). The Implementing Regulation requires in particular an accounting system consistent with generally accepted accounting principles, which facilitates audit-based customs control and maintains a historical record of data providing an audit trail (Art. 25). This is often the most demanding criterion for medium-sized companies, because it requires physical flows, accounting flows and customs declarations to be capable of being reconciled.
The third criterion is proven solvency (Art. 39(c)). It is fulfilled where the applicant is not subject to bankruptcy proceedings, has fulfilled its financial obligations regarding payment of duties and taxes connected with import or export during the last three years, and demonstrates sufficient financial standing, in particular no negative net assets unless they can be covered (Art. 26 of the Implementing Regulation). A company established for less than three years is assessed on the basis of the records and information available.
The fourth criterion, specific to AEOC, is compliance with practical standards of competence or professional qualifications directly related to the activity carried out (Art. 39(d)). It is fulfilled where the applicant or the person in charge of customs matters has proven practical experience of at least three years in customs matters, applies a customs quality standard adopted by a European standardisation body, or has successfully completed training covering customs legislation provided by an approved entity (Art. 27 of the Implementing Regulation). The fifth criterion, specific to AEOS, is the existence of appropriate security and safety standards: physical integrity and access control, logistical processes, handling of specific types of goods, personnel and business partners (Art. 39(e) and Art. 28 of the Implementing Regulation).
4. The procedure: questionnaire, audit, decision
The application is accompanied by a self-assessment questionnaire made available by the customs authorities (Art. 26(1) of Delegated Regulation 2015/2446). The operator submits a single application covering all its permanent business establishments in the Union (Art. 26(2)). The authorities then carry out on-site checks at the premises where the applicant carries out customs-related activities (Art. 29 of the Implementing Regulation).
The decision is taken within the standard period of one hundred and twenty days from acceptance of the application (Art. 22(3) of the Code), which may be extended by no more than sixty days, and longer where pending criminal proceedings raise doubts as to compliance with the infringements criterion (Art. 28 of the Delegated Regulation). The authorisation takes effect on the fifth day following the decision (Art. 29 of the Delegated Regulation).
The questionnaire is no formality. The answers it contains are reread by the auditors and compared with the documents and with what they find on site, and an inaccurate answer, even one given in good faith, undermines the credibility of the entire application, which comes at a price when the administration has to decide whether a past infringement is or is not of minor importance within the meaning of Article 24(2) of the Implementing Regulation, an assessment in which the trust it places in the applicant plays a decisive role. An honest, documented answer about a past incident is better than a smooth answer that the audit will contradict.
Rejection of an application has no effect on favourable decisions already taken, unless they were based on a criterion of the status which the examination showed was not met (Art. 32 of the Implementing Regulation). The risk of a refusal is therefore not nil for existing authorisations.
5. After the grant: monitoring, suspension, revocation
The status is subject to monitoring (Art. 38(1) of the Code). The holder must inform the authorities without delay of any event arising after the decision that may affect its continuation or content (Art. 23(2)). A change of managing director, a warehouse move, a reorganisation of the customs function, insolvency proceedings, the arrival of a new controlling shareholder, the departure of the customs manager who led the application, the opening of a new logistics site in another Member State, outsourcing customs clearance to a provider not envisaged in the original file: all of this may affect the criteria, and all of this must be reported, preferably before the administration discovers it for itself during a reassessment.
Where a status authorisation is suspended for failure to meet one of the criteria, any decision based on the status in general or on the criterion concerned is also suspended (Art. 30(1) of the Delegated Regulation). The reverse is not automatic: suspension of a decision taken in respect of an AEO does not entail suspension of its status (Art. 30(2)). Revocation of the status, for its part, does not affect favourable decisions already taken, unless the status was a condition for them or they are based on a criterion that is no longer met (Art. 34 of the Implementing Regulation).
In practice, a company that has built its customs clearance organisation on simplifications obtained thanks to AEOC status may see that whole organisation undermined by a serious infringement or a deterioration in its financial position. The status is won once. It is maintained every day.
6. Preparing the application without stirring up a dispute
Preparing an AEO application is a customs compliance audit. It almost always brings to light classification, valuation or origin errors, poorly documented procedures and imprecise representation mandates. That is its main benefit. It is also its main risk, because the administration’s audit may discover these errors before the company has corrected them.
The order matters. First, an internal diagnostic covering the last three years, conducted under the direction of an adviser. Next, dealing with the anomalies: correcting declarations where possible, regularising national charges where the right to make mistakes applies (Art. L. 313-1 of the Customs Code, which nevertheless excludes customs duties themselves), applying for repayment where the company has overpaid, and taking a considered decision on what should be reported to the administration. Finally, the application, with a questionnaire describing a cleaned-up situation and procedures that work.
Past infringements must be addressed head on. A settlement concluded with the administration does not make the facts disappear, and it is in the light of Article 24 of the Implementing Regulation that the authority will assess whether they are serious, repeated or of minor importance. The quality of the defence conducted at the time, the amounts at stake relative to the volume of operations and the corrective measures taken since then then form the heart of the argument.
For the Mulhouse company, the 2024 settlement is not an insurmountable obstacle. An isolated valuation error, of a modest amount in relation to thousands of declarations, followed by a correction of procedures, is typically an infringement of minor importance. That still has to be shown, with supporting documents, rather than hoping the auditor will not notice it. The auditor will.

Frequently asked questions
What is the difference between AEOC and AEOS?
AEOC (customs simplifications) gives access to the simplifications provided for under customs legislation; AEOS (security and safety) gives entitlement to facilitations relating to security (Art. 38(2) of the Union Customs Code). Both may be held together, in the form of a combined authorisation. The competence criterion is specific to AEOC, the security criterion to AEOS.
What are the practical benefits of AEO status?
Fewer physical and document-based controls, advance notification when a consignment is selected for control, priority controls and, on request, controls carried out elsewhere than at the place of presentation (Art. 24 of Delegated Regulation 2015/2446). For AEOC, criteria already verified are not re-examined when applying for simplifications (Art. 38(5) of the Code). These benefits do not apply to controls related to elevated threat levels.
Does a past infringement prevent a company from obtaining AEO status?
Not necessarily. The criterion concerns serious or repeated infringements during the last three years (Art. 39(a) of the Code; Art. 24 of Implementing Regulation 2015/2447). It may be considered fulfilled where the infringement is of minor importance in relation to the volume of operations and the administration has no doubts as to the applicant’s good faith.
How long does the procedure take?
The decision is taken within one hundred and twenty days of acceptance of the application (Art. 22(3) of the Code), a period that may be extended by sixty days, and longer in the event of pending criminal proceedings (Art. 28 of the Delegated Regulation). The authorisation takes effect on the fifth day following the decision. Internal preparation beforehand often takes several months.
Can AEO status be withdrawn?
Yes. The status is subject to monitoring and may be suspended or revoked if a criterion is no longer met. Suspension extends to decisions based on the status or on the criterion concerned (Art. 30 of the Delegated Regulation); revocation affects other decisions only if the status was a condition for them (Art. 34 of the Implementing Regulation).
