Mediation under EU marketplace rules: what it means for marketplace

A suspension notice arrives. The listings are gone, the selling account is restricted, and the only thing an Amazon IT seller sees is a generic reference to policy. No clear appeal path. No obvious lever. That is the moment when the gap between US marketplace practice and EU marketplace law becomes commercially costly – and when the options that EU rules actually provide start to matter.

TL;DRMediation under EU marketplace rules is a formal dispute-resolution mechanism that gives Amazon IT sellers the right to request independent mediation when a platform decision – such as a suspension, a listing removal, or a contract restriction – cannot be resolved through the platform's internal complaint-handling system. The Platform-to-Business (P2B) Regulation and, for larger platforms, the Digital Services Act (DSA) together define those rights. They are enforceable, not advisory.

This analysis works through the mechanics: what mediation under EU marketplace rules is on Amazon IT, the realistic procedural path a seller takes from suspension to mediation, and the decision points and trade-offs a seller faces at each stage. It is written for founders, operations leads, and in-house teams who need a decision-grade read on what is still open.

Why EU Marketplace Rules Create a Different Starting Position

EU marketplace law places mandatory procedural obligations on platforms before the question of mediation even arises – and those obligations shift the commercial position of a suspended seller significantly.

In the US context, a seller whose Amazon account is deactivated is working within the terms of the Amazon Business Solutions Agreement (BSA). The BSA governs appeals, and its dispute-resolution provisions (which vary by account version) determine what formal paths exist. In the EU, the P2B Regulation layers on top of the contract. It applies to all online intermediation services, including Amazon, operating in EU member states. Amazon IT – Amazon's Italian marketplace – is directly in scope.

What does that mean practically? The P2B Regulation requires that platforms provide sellers with a statement of reasons before restricting, suspending, or terminating an account. It also requires that platforms operate an internal complaint-handling system that is accessible, free of charge, and capable of resolving complaints within a reasonable time. Only where the internal complaint-handling system fails to resolve a dispute does the P2B Regulation's mediation right become available. This is not a shortcut. It is a second-stage right that opens after the internal route is genuinely exhausted or blocked.

In matters we handle, sellers on Amazon IT frequently arrive with a suspension notice that either omits the required statement of reasons entirely or gives one so thin it cannot be acted on. That is itself a compliance problem for the platform – one that affects the seller's position in the internal complaint and, if needed, in mediation.

The DSA adds a further layer for Amazon, which the European Commission designated as a Very Large Online Platform (VLOP). Under the DSA, Amazon must operate a statement-of-reasons mechanism for content removals and must maintain an internal complaint-handling system for sellers and users. The DSA's complaint and redress rights partially overlap with the P2B framework, but the DSA's specific obligations around transparency and content moderation reinforce the seller's position when pushing for a substantive review.

For EU sellers exploring the full picture of these frameworks, our EU marketplace regulation guide for sellers sets out how the P2B Regulation, DSA, and Digital Markets Act (DMA) interact and what each means for account disputes.

What Does the Mediation Mechanism Actually Look Like?

The P2B Regulation requires platforms above a defined size threshold to identify, in their terms, at least two qualified mediators they are willing to engage with. Mediation under the Regulation is not compulsory for the platform in the sense that a court order is – but the platform is obliged to engage in good faith with any mediation a seller validly initiates through a listed mediator.

The key mechanics sellers need to understand:

• The right arises only after the internal complaint-handling system has been used and has not resolved the dispute. Jumping straight to mediation before engaging the internal system will typically result in the mediator declining jurisdiction.
• The mediation is confidential. Positions taken and documents shared during mediation cannot be used as evidence in later court or arbitration proceedings unless both parties agree.
• Costs are shared between the platform and the seller, but the Regulation caps the seller's share at a reasonable level. In practice, the platform's obligation to engage with listed mediators tends to moderate costs compared with formal arbitration.
• The outcome of P2B mediation is not automatically binding. The parties can agree a settlement; if they do not, the seller's remaining options are judicial or, for Amazon accounts, the BSA dispute path.
• For Amazon as a VLOP under the DSA, the internal complaint-handling system must be free of charge and must process complaints within a reasonable period. A failure to meet that standard is a compliance violation that a seller can raise both in mediation and with EU national Digital Services Coordinators.

In practical terms, mediation under EU marketplace rules on Amazon IT involves: an initial escalation through Seller Central's complaint mechanism, a formal written complaint asserting P2B rights, a waiting period for the platform's substantive response, and – if that response is inadequate – a formal request for mediation through one of the mediators Amazon has identified in its terms for EU business sellers.

What changes between Amazon EU marketplaces? The mediators listed in Amazon's terms, and the specific procedural steps for escalation through Seller Central, can differ. Amazon IT operates under Amazon's EU business-seller terms, which are governed by Luxembourg law – but the P2B Regulation applies as EU law across all member states. The procedural substance of the rights is the same in Italy, Germany, and France; the contact points and supporting documentation requirements may vary in practice.

How Does the Suspension Trigger This Path?

The realistic procedural path for an Amazon IT seller facing a suspension under EU rules runs in a defined sequence, and understanding where a seller currently sits in that sequence is the first analytical task.

Stage 1: Notice and statement of reasons. Under P2B, Amazon must provide a statement of reasons before or at the point of suspension (with limited exceptions for immediate action on safety or legal grounds). The statement should explain the grounds, the facts, and the contractual basis. If the notice a seller receives does not meet this standard, that is the first lever – a formal demand for a compliant statement of reasons is the foundation of everything that follows.

Stage 2: Internal complaint. The seller submits a written complaint through the internal complaint-handling system, identifying the specific P2B ground and requesting review. In matters we handle on Amazon IT, a well-constructed complaint at this stage references the statement of reasons, identifies the factual error or procedural gap, and requests reinstatement within a defined window. The internal system's response – or failure to respond – then determines whether the mediation right crystallizes.

Stage 3: Mediation initiation. If the internal complaint does not produce a satisfactory resolution – meaning the suspension is upheld without adequate justification, or the platform simply does not engage substantively – the seller may initiate mediation with one of the platform's listed mediators. The request typically requires a short written statement of the dispute, the prior complaint record, and identification of the outcome sought.

Stage 4: Mediation itself. A qualified neutral facilitates discussion between the seller and the platform. The mediator does not decide; they assist the parties in reaching agreement. The seller's goal is typically either reinstatement, a compliant statement of reasons for the refusal, or both.

Stage 5: Post-mediation options. If mediation does not produce a settlement, the seller may pursue judicial remedies in the relevant EU member state or, depending on the BSA terms applicable to the account, the contractual dispute path. For sellers concerned about parallel listing or safety complaints that triggered the suspension, those separate tracks also remain open.

A useful comparison: if the suspension arose from a product safety or CE marking complaint, the technical dispute track and the P2B mediation track run in parallel – and the outcome of one can inform the other. Our analysis of EU listing takedowns on safety grounds sets out how that technical track works and where it intersects with the complaint and mediation path.

What Are the Seller's Real Decision Points?

Mediation under EU marketplace rules is not the right tool in every situation. The commercial and procedural trade-offs deserve a clear read.

Is the suspension genuinely a P2B or DSA issue? Not all Amazon IT suspensions engage EU marketplace law in a way that makes mediation the strategic priority. If the suspension is driven by a performance metric (order defect rate, late dispatch) rather than a platform policy decision, the P2B statement-of-reasons right applies but the practical lever may be the standard Amazon appeal process first. If the suspension follows a rights-owner complaint – a trademark or product-safety report – the IP or safety track may move faster. The decision matrix: if the notice cites a platform policy ground without a clear factual basis, and the internal complaint produces no substantive engagement, then mediation is the next logical step. If instead the notice cites a seller performance issue and the internal system responds with a corrective-action path, standard reinstatement work may resolve the matter without reaching mediation.

Time and cash-flow cost. P2B mediation takes time – typically several weeks from initiation to conclusion, depending on the mediator's schedule and the platform's responsiveness. For a seller with inventory stranded at an Amazon IT fulfillment center and a disbursement cycle interrupted, that timeline is a commercial cost. The decision whether to pursue mediation, pursue a parallel judicial emergency measure, or both simultaneously is partly a cash-flow calculation. We regularly see sellers underestimate this timeline and make tactical concessions they didn't need to make simply because they ran out of runway.

What outcome can mediation realistically produce? The realistic options are: a negotiated reinstatement (the most common and most commercially valuable outcome); a compliant statement of reasons that enables a further judicial challenge; or, where the underlying dispute turns on a factual matter the platform is willing to revisit, a corrective agreement. Mediation does not produce a judgment. It does not bind the platform to reinstate if the mediator recommends it. Its leverage is the platform's reputational and regulatory interest in good-faith engagement – and, in the case of a DSA VLOP, its regulatory compliance interest before EU Digital Services Coordinators.

What does a well-constructed mediation request look like? In our practice, the requests that produce substantive engagement share certain characteristics: they are precise about the P2B obligation allegedly breached, they reference the internal complaint record, they are proportionate in the remedy sought, and they do not over-claim. A mediation request that reads like a demand letter will not move a platform compliance team; one that reads like a considered legal analysis of the gap between the statement of reasons provided and the P2B standard required will.

For sellers dealing with a CE marking or product safety component to the suspension, the interaction between the technical compliance track and the P2B mediation track is a separate strategic question. Our analysis of CE marking complaints and delistings addresses that interplay.

The DSA and DMA: What They Add to the Seller's Position

The DSA and Digital Markets Act (DMA) are not simply background – for sellers on Amazon IT, they add material procedural rights that interact with P2B mediation in concrete ways.

Under the DSA, Amazon as a VLOP must: maintain an internal complaint-handling system for sellers and users; provide clear, specific, and individually targeted statements of reasons for account restrictions; and, when asked, review decisions through a process that is not operated exclusively by automated means. That last point matters. A significant share of Amazon IT suspensions in our practice appear to originate from automated policy enforcement. The DSA provides an explicit right to request non-automated review – a right that sits alongside and reinforces the P2B internal complaint right.

The DMA applies to Amazon as a designated gatekeeper in the online intermediation market. It imposes specific obligations on Amazon's commercial conduct toward business users, including restrictions on self-preferencing and data use. In a mediation context, DMA obligations are less directly relevant than P2B/DSA rights – but a suspension that appears to follow a pattern of discriminatory enforcement or systematic disadvantage for third-party sellers may raise DMA questions worth noting in a formal complaint to the relevant regulatory body.

The practical question for a seller in mediation: can DSA and DMA rights be raised in P2B mediation? The answer is nuanced. P2B mediation governs the contractual relationship between the platform and the business user. DSA/DMA rights are public-law obligations enforceable by regulators, not directly by individual sellers in mediation. However, a seller can reference Amazon's DSA compliance obligations as context in a mediation statement – as evidence that the platform's conduct falls below the standard it is legally required to meet – without claiming private enforcement of those obligations in mediation.

The more direct use of DSA and DMA levers is a parallel complaint to the Italian Digital Services Coordinator or the relevant EU regulator. That path does not resolve the individual account suspension in the way mediation can, but it creates regulatory pressure and a compliance record that can matter in protracted disputes.

Two Scenarios from Practice

An apparel seller on Amazon IT (spring 2025) came to us after a full account suspension citing a generic "policy violation" with no specifics in the notice. The seller had used the internal complaint system and received a template acknowledgment with no substantive engagement. We reviewed the deactivation notice, identified the failure to provide a P2B-compliant statement of reasons, and built the internal-complaint case around that specific gap. Before the mediation stage was needed, the platform reviewed the complaint and provided a substantive statement of reasons – which disclosed that the trigger had been a mislabeled ASIN linked by an automated system to the main account. The corrective case was filed on the actual root cause, and the account was restored.

A consumer-electronics distributor on Amazon IT (winter 2026) had a different experience: the internal complaint produced a detailed, technically argued refusal citing CE marking documentation gaps. Mediation was initiated. The mediation process produced a structured discussion that ultimately turned on one document that the platform's automated review had flagged as absent but which the seller held. The mediator facilitated the production of that document in a format the platform's compliance team accepted, and the listing was restored under a remediation agreement. No judicial step was needed. The outcome was not guaranteed by the process – it followed from a correctly constructed mediation case.

What Sellers Get Wrong When They Try This Alone

What is the most common way this goes wrong? Sellers who move to mediation without first establishing a clear internal complaint record effectively give the mediator less to work with. The P2B mediation process derives its structure from the prior internal-complaint record. A thin or poorly argued internal complaint leads to a thin mediation case.

The second consistent error is conflating EU mediation with the US Plan of Action (POA) process. The POA model – root cause, corrective action, preventive measures – is the right format for Amazon US reinstatement. For P2B mediation on Amazon IT, the document that does the equivalent work is a structured legal complaint that references the specific P2B obligation breached, the evidence supporting the seller's position, and the remedy sought. Sellers who submit a POA-format document as their P2B complaint consistently receive responses that do not engage with the EU-law basis for the complaint.

A third error: believing that EU sellers have no leverage once a platform suspends them. That is the myth that EU marketplace law was specifically designed to address. The P2B Regulation's statement-of-reasons requirement, internal complaint right, and mediation mechanism all exist precisely because EU legislators recognized that the power asymmetry between platforms and business users required a legal correction. Using those rights effectively requires understanding exactly what each stage requires – not that they don't exist.

Finally, sellers underestimate the importance of timing. The internal complaint should be filed promptly after receiving the suspension notice and the (inadequate or absent) statement of reasons. Delays allow the platform's internal record to become fixed, make it harder to reconstruct the timeline, and – if a judicial emergency measure ever becomes relevant – reduce the options for urgency.

If you have already filed an internal complaint that came back with a template refusal, a second, properly structured read of that response can identify the specific ground on which the platform's position is weakest, and whether mediation or a parallel route is more likely to produce results.

The Operator's Calculation: When Is Mediation Worth Pursuing?

For a marketplace seller, mediation under EU marketplace rules is not a principled exercise in regulatory rights for its own sake. It is a commercial tool. The question is whether it is the right tool in a given situation, on a given timeline, at a given cost.

The case for mediation is strongest when: the internal complaint has genuinely been exhausted without a substantive response; the P2B ground is clear (missing or inadequate statement of reasons; no good-faith engagement with the internal complaint); the seller has the documentation to support a well-constructed mediation request; and the commercial value of the suspended account justifies the time and cost of the process.

The case is weaker when: the internal complaint has not yet been fully pursued; the suspension turns on a straightforward factual error that the standard Amazon appeals process can correct; or the seller's primary issue is a parallel technical compliance matter (CE marking, GPSR, EPR) where the technical track should move first.

A word on timing relative to other actions: P2B mediation and judicial emergency measures (injunctions) can in principle run in parallel, but courts in EU member states will generally expect to see evidence that internal remedies and mediation have been attempted before granting emergency relief. That sequence matters for how a seller builds the record from the first day after suspension.

In terms of fees: mediation under EU marketplace rules is one of the practice areas where we work to fixed-fee arrangements, quoted up front after a short review of the account situation and the prior correspondence. The scope and cost depend on where in the process the matter sits – early-stage internal complaint work, a mediation filing, or representation through the mediation itself. We do not quote a mediation fee before reviewing the suspension notice and internal complaint record, because those documents define the scope of what is actually needed.

Frequently Asked Questions

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

The full process – internal complaint through to a mediation outcome – typically takes several weeks to a few months, depending on the mediator's schedule and the platform's responsiveness at the internal complaint stage. The internal complaint phase can sometimes resolve the dispute without reaching formal mediation, which shortens the timeline considerably. Where formal mediation proceeds, the duration turns on the complexity of the underlying issue and whether documentary questions can be resolved quickly. No specific timeline is guaranteed by the process, and the commercial cost of the duration is a factor sellers should plan for before initiating.

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

The primary risk is a poorly constructed internal complaint that weakens the mediation record before the formal process even begins. Sellers who approach P2B mediation using the format of an Amazon US Plan of Action consistently receive non-substantive responses, because the P2B complaint requires a specific legal structure that references EU-law obligations rather than Amazon's internal quality standards. A second risk is timing: failing to file the internal complaint promptly, or missing the practical window for escalation, can limit what is available later. A third is scope: conflating EU mediation rights with DSA complaint rights or judicial options, and pursuing the wrong track first.

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

There is no formal requirement for legal representation in P2B mediation. However, in matters we handle, the outcome of mediation turns significantly on how the internal complaint and mediation request are constructed. These are legal documents in substance – they reference specific EU regulatory obligations, identify the legal standard the platform must meet, and define the remedy sought in terms the mediator can work with. A seller with a clear understanding of P2B and DSA obligations can construct a competent case. For most Amazon IT sellers dealing with a suspension while managing a live business, the time and risk cost of getting this wrong is the main reason to use legal assistance for at least the internal complaint and mediation filing stages.
