How one seller resolved mediation under EU marketplace rules

A suspension on Amazon IT looks, in the first hours, like a wall with no door. The listing is gone. The account dashboard shows a policy violation. The seller's emails to Seller Central come back templated. What the deactivation notice does not say – and what most sellers on the Italian marketplace do not yet know – is that EU law creates a second path that runs parallel to Amazon's own appeal process. This case study follows one anonymized seller who used that path to force a result that the standard appeal queue had already rejected.

TL;DRMediation under EU marketplace rules is a formal dispute-resolution mechanism that platforms operating in the EU must offer sellers under the Platform-to-Business (P2B) Regulation. On Amazon IT, this means an accredited external mediator can be engaged after the platform's internal complaint process has been exhausted. It is not a second appeal to Amazon. It is a structured, third-party process with its own procedural rights – and, in many matters, it is the lever that finally moves a suspended or delisted account.

The sections below trace the situation as it came to us, what was really happening beneath the surface, the strategy we recommended, the decision points along the way, and the lesson this account offers to any EU seller who has been told their suspension is final.

What brought this seller to us – and what the notice actually said

A suspension notice that cites a policy violation does not necessarily mean the platform has proved one. The seller in this matter – a mid-size accessories brand selling on Amazon IT for several years – received a listing suspension that Amazon's system classified as a product-compliance failure. The notice referenced a general product-safety concern. No specific test report was identified as deficient. No customs or regulatory authority had flagged the product. The seller had CE marking documentation and a declaration of conformity already on file in Seller Central.

The seller had gone through Amazon's standard review process twice. Both submissions were rejected without substantive comment – the response cited the same policy category, with no indication of what specifically remained unsatisfied. By the time the seller reached Tutamen, inventory sat in an Italian fulfillment center, the selling season was advancing, and the internal appeal channel felt closed.

Two things were immediately clear from reading the deactivation history. First, Amazon had not provided a statement of reasons adequate to let the seller identify and cure the actual deficiency. Second, the seller had not yet engaged the external complaint and mediation track that the P2B Regulation requires Amazon to make available to business sellers in the EU. That track had not been exhausted – because the seller did not know it existed.

In matters we handle on the EU regulatory side, this gap is common. Most sellers are unaware that the internal complaint-handling system Amazon operates under Article 11 of the P2B Regulation is separate from – and prior to – the mediation process. Working through that sequence correctly is what determines whether mediation is even open as an option.

What was really happening procedurally – the P2B and DSA layer

The P2B Regulation gives business sellers on platforms operating in the EU a right to a statement of reasons before or at the time of any restriction, suspension, or termination of their account or listings. That statement of reasons must be specific enough to allow the seller to understand the actual ground for the measure and to challenge it. A generic policy category does not satisfy this requirement.

The Digital Services Act (DSA) – which applies to Amazon as a Very Large Online Platform (VLOP) – adds further obligations. Platforms must provide a statement of reasons for content-moderation decisions and must maintain an internal complaint-handling system that gives sellers a meaningful opportunity to reverse or adjust a decision. Critically, the DSA's statement-of-reasons obligation applies to listing takedowns in certain contexts, reinforcing the P2B baseline.

For an in-depth breakdown of how these instruments interact for sellers on EU marketplaces, see our EU marketplace regulation guide for sellers.

In this seller's case, the two standard appeal submissions had been made directly into Amazon's Seller Central appeal flow, which is the platform's own internal process. That process had returned two rejections. Under the P2B framework, once a seller has engaged the internal complaint-handling system in good faith and received an outcome they dispute, the mediation track becomes available. The seller had not been informed of this in the rejection notices. That omission is itself a procedural issue worth raising.

What the seller was actually facing, therefore, was not simply a failed appeal. It was an inadequate statement of reasons (the original suspension) followed by an internal complaint process that had run without resolution. The next procedural step – mediation with one of the mediators Amazon is required to identify under Article 12 of the P2B Regulation – had never been initiated.

How the strategy came together – and what we recommended against

The first question we asked was whether the compliance documentation gap, if any existed, could be closed quickly. After reviewing the seller's CE marking file, the declaration of conformity, and the test reports, we concluded the documentation was materially complete. The likely issue – and this is pattern we see regularly in product-safety suspensions on Amazon IT – was not a documentation deficiency but a failure in how the documents had been presented to Amazon's review team, combined with Amazon's system not linking the uploaded files to the specific ASIN in question.

We recommended against a third standard appeal submission. A third filing into the same queue, with the same structure, after two rejections, rarely produces a different result if the underlying framing has not changed. More importantly, it risked establishing a pattern of exhausted remedies within the platform's own system – which could actually complicate the mediation filing, depending on how the mediator assessed the procedural history.

The strategy had three components. First, we drafted a formal internal complaint under the P2B Regulation's Article 11 mechanism, addressed to Amazon's business-seller complaint channel (separate from standard Seller Central appeals). This complaint identified the specific statement-of-reasons deficiency, attached the compliance documentation with a structured index, and formally demanded either reinstatement or a specific written explanation of the remaining deficiency. Second, we prepared the mediation filing to be ready to submit if the internal complaint did not produce a substantive response within a reasonable period. Third, we documented the commercial impact – not with invented figures, but with a clear factual record of inventory location, seasonal demand context, and the cost of further delay – to support the mediation submission if it became necessary.

Product-safety delisting on EU marketplaces raises a cluster of overlapping compliance questions. Our piece on EU listing takedowns on safety grounds covers the regulatory context that shapes how these submissions are received.

The decision points and trade-offs

At the point of engaging us, the seller faced three options. The first was to refile a standard appeal, accept the risk of another rejection, and hope a different reviewer saw the documentation differently. The second was to go directly to mediation without exhausting the formal internal complaint route. The third was the two-stage approach we recommended: internal complaint under P2B first, then mediation if needed.

The trade-off on option one was speed against probability. Refiling is fast. But after two substantive rejections on the same classification, the probability of a different outcome without a procedural change is low. The trade-off on option two – jumping straight to mediation – was that the mediator's jurisdiction under Article 12 is only available after the internal complaint mechanism has been used. Going directly to mediation without that prior step risked a procedural dismissal at the threshold.

The two-stage path we recommended was slower, but it preserved every option. An internal complaint under P2B could itself produce reinstatement – in which case mediation would never be needed. If it did not, the mediation filing would rest on a complete procedural record, including Amazon's response (or non-response) to the formal complaint. That record is material. A mediator assessing a dispute where the platform failed to provide an adequate statement of reasons, and then failed to respond substantively to a formal internal complaint, is looking at a different picture than a mediator presented with a seller who simply didn't like the outcome of two appeal rejections.

The seller also asked whether arbitration under an alternative dispute-resolution framework was available. We assessed this against the BSA version applicable to the account – the path depends on the BSA version that applies to the account, which we check first – and concluded that the EU regulatory mediation route was the more direct and proportionate tool for this dispute at this stage.

An analogous strategic analysis for sellers on Amazon DE – where CE marking issues arise in a similar regulatory context – appears in our guide to handling CE marking complaints and delisting on Amazon DE.

Outcome and what the result actually means

An accessories brand on Amazon IT (winter 2026) reached Tutamen after two standard appeals had been rejected on a product-compliance classification that the seller's documentation did not, on review, support. We drafted a formal P2B internal complaint identifying the statement-of-reasons deficiency, submitted it with a structured documentation index, and set a defined response window. Amazon's business-seller team responded within that window with a specific and different deficiency identification – not the generic classification in the original notice. The identified gap was a missing test scope notation on one sub-component. The seller's testing laboratory was able to issue a supplementary test report confirming the existing scope covered that sub-component. The listing was reinstated. Mediation was not ultimately required because the internal complaint procedure produced a substantive result – but the mediation filing was prepared and ready, and the seller knew before the internal complaint was sent that the next step was procedurally available and already structured.

What this outcome demonstrates is not that EU mediation is a magic route. It is that using the correct procedural sequence – internal complaint under P2B before mediation, with a substantive legal argument built on the statement-of-reasons failure – changes the nature of the platform's response. Amazon's internal complaint channel, when engaged formally under the regulatory framework rather than as a repeat Seller Central appeal, routes to a different review team. That team has different accountability than the standard appeal queue.

The result was also partly shaped by the documentation itself. CE marking and conformity documentation is only useful in a dispute if it is presented in a way that a non-technical reviewer can trace to the specific ASIN and the specific regulatory concern. Generic uploads to Seller Central rarely achieve that. A structured submission does.

The lesson for other EU marketplace sellers

Most sellers facing a suspension on an EU marketplace – Amazon IT, Amazon DE, Amazon FR, or any other surface covered by the P2B Regulation and the DSA – do not know that a formal complaint mechanism exists outside the platform's own appeal flow. They exhaust the appeal queue, receive rejections, and conclude the decision is final. It is not. The regulatory architecture the EU has built for platforms operating here gives business sellers rights that the platform's own interface does not advertise.

The myth worth addressing directly: EU sellers are not without leverage once a platform suspends them. This is the assumption that keeps sellers from using the rights they have. The P2B Regulation requires platforms to offer mediation. The DSA requires adequate statements of reasons. The Digital Markets Act (DMA) imposes further obligations on Amazon as a gatekeeper designation candidate. These instruments are not aspirational. They carry enforcement consequence, and a well-structured complaint invokes them in a way that a standard Seller Central appeal does not.

The practical lesson from this matter is procedural: exhaust the correct sequence. Internal complaint under P2B first, with a written argument built on the specific regulatory failures in the suspension notice. Mediation second, if the internal complaint does not produce a substantive result. Document the commercial impact throughout. Keep the record complete and dated. The mediator, if mediation is reached, will assess the quality of that record – and so will any regulatory authority that later looks at the platform's handling of the complaint.

EU sellers who believe a suspension is final because two Seller Central appeals have been rejected are, in most cases, at the beginning of the procedural path – not the end of it.

Frequently asked questions

How long does resolving mediation under EU marketplace rules usually take on Amazon IT?

The timeline varies significantly depending on whether the matter resolves at the internal-complaint stage or proceeds to formal mediation. In many matters we handle, a well-structured internal complaint under Article 11 of the P2B Regulation produces a substantive platform response within several weeks. If the internal complaint does not produce reinstatement and formal mediation is initiated, the process typically runs longer – often several additional weeks to months – depending on mediator availability, the complexity of the underlying compliance question, and how quickly the platform engages. The internal complaint stage should always be completed first, as it is a prerequisite to mediation and sometimes resolves the dispute without it.

What are the main risks if I handle mediation under EU marketplace rules alone?

The primary risk is procedural: engaging the wrong channel in the wrong sequence, which can foreclose options that would otherwise have been open. Sellers who go directly to mediation without first exhausting the P2B internal complaint mechanism risk a threshold dismissal. Sellers who file mediation submissions without a substantive legal argument – built on the statement-of-reasons failure and the specific regulatory obligations the platform owes – often receive a result that mirrors the appeal rejections they already have. A second practical risk is documentation framing: compliance files that are technically adequate but presented without a clear link to the specific ASIN and regulatory concern are routinely insufficient, even in mediation. The regulatory framing is what makes the difference between a filing that reads as another appeal and one that reads as a formal rights-based challenge.

Do I need a lawyer for mediation under EU marketplace rules?

Legal representation is not formally required, but the practical difference between a represented and an unrepresented seller in EU marketplace mediation is significant. The P2B Regulation and the DSA create specific procedural obligations on the platform, and invoking them correctly – identifying the statement-of-reasons deficiency, framing the internal complaint in regulatory terms, and structuring the mediation submission against the mediator's assessment criteria – requires familiarity with both the instruments and the platform's internal processes. In matters we handle, attorney-led submissions are consistently better positioned than self-filed complaints, not because of credential formality but because the legal argument changes the nature of the platform's response. For matters where the commercial stakes are material, the cost of getting the sequence wrong substantially outweighs the cost of professional guidance.
