EU Marketplace Regulation: the complete guide for sellers

TL;DREU marketplace regulation is the body of rules – principally the Digital Services Act (DSA), the Digital Markets Act (DMA), the Platform-to-Business (P2B) Regulation, and the General Product Safety Regulation (GPSR) – that governs how platforms like Amazon must treat third-party sellers in Europe and, in important respects, how those rules now reach US-based sellers trading into EU marketplaces. A suspension or delisting under these rules is not final: EU law gives sellers the right to a reasoned explanation, an internal complaint channel, and, where the platform qualifies as a gatekeeper or Very Large Online Platform, additional procedural protections that most sellers never use.

As enforcement automation has tightened across EU marketplaces, the cases reaching our practice increasingly involve sellers who received a suspension notice with little explanation and assumed the decision was unchallengeable. It is not. The purpose of this guide is to map the entire EU regulatory regime as it applies to marketplace sellers – what each instrument covers, how the procedural path actually works, where the leverage sits, and what the realistic decision points are. This is the hub page for Tutamen's EU practice cluster; the sections below carry links to deeper spoke pages on each topic.

What EU Marketplace Regulation Actually Is – and Why It Reaches US Sellers

EU marketplace regulation is not a single statute – it is a layered regime, and understanding which layer applies to a given situation determines the entire strategy.

The P2B Regulation (Regulation 2019/1150) was the foundation. It imposed minimum transparency and fairness obligations on platforms offering intermediation services to business users established in the EU: written terms, a statement of reasons before restricting or terminating an account, an internal complaint-handling system, and access to mediation. The P2B rules were designed specifically for the seller-platform relationship and remain directly relevant to most suspension disputes today.

The DSA elevated and broadened those obligations. Amazon is designated as a Very Large Online Platform (VLOP) under the DSA, meaning it faces the most demanding tier of requirements: detailed statements of reasons when content or accounts are restricted, a reinforced internal complaint mechanism, access to certified out-of-court dispute settlement bodies, and compliance auditing. For sellers, the practical payoff is a cleaner, more defensible paper trail and a formal channel to push back when a restriction is poorly explained.

The DMA creates a separate set of obligations for platforms designated as gatekeepers. Amazon has been designated as a gatekeeper for several of its core platform services. The DMA's obligations – non-discrimination, data access, self-preferencing limits – are primarily structural and compete-law adjacent. They matter most to sellers who believe the platform is systematically disadvantaging third-party listings relative to Amazon's own retail offers. In matters we handle, the DMA argument is rarely the first tool, but it becomes relevant in systemic-exclusion cases.

The GPSR replaced the old General Product Safety Directive in December 2024 and tightened the obligations on economic operators – including marketplace sellers – around product traceability, responsible person requirements, and incident reporting. A product safety suspension on Amazon EU is now more likely to cite GPSR than the old directive, and the response needs to address the correct instrument.

Where does a US-based Amazon seller fit? If you sell into Amazon.de, Amazon.fr, Amazon.it, Amazon.es, or Amazon.co.uk (which retains parallel UK rules), the EU-side obligations apply to your listings regardless of where your business is incorporated. Your Amazon account is subject to the relevant P2B and DSA protections even if you have never set foot in Europe. The marketplace's terms, and the underlying regulation, follow the listing, not the seller's location.

How Does the Suspension and Delisting Process Actually Work Under EU Rules?

Under the P2B Regulation and the DSA, a platform restricting or terminating a business user's account must provide a statement of reasons before or, in the case of urgent restrictions on illegal content grounds, immediately after the restriction takes effect.

In practice, the statement of reasons is often thin. A notice citing "violation of selling policies" without identifying the specific policy, the specific listing, or the evidence the platform relied on is not, on its face, a compliant statement of reasons under EU law. That gap is the starting point for many of the cases we work on. The first task is always to read the notice carefully and identify exactly what was and was not explained.

The procedural sequence generally runs as follows. The seller receives a restriction notice. Within the notice or accompanying it, the platform must identify the facts, the rules, and – where AI or automated means are used – the fact that automated decision-making was involved. The seller then has access to the internal complaint-handling system. For Amazon as a VLOP, that system must be effective, meaning it has to be staffed, not merely nominal. A response that ignores the substance of the complaint and restates the original decision in identical terms is a failure of the DSA's requirements – and one that can be escalated.

If the internal process does not produce a satisfactory outcome, EU sellers have two additional routes: certified out-of-court dispute settlement bodies (an innovation of the DSA) and – for systemic issues – the Digital Services Coordinator in the relevant member state. For US sellers trading into the EU, the practical access to those bodies depends on which marketplace is involved and where the dispute is centered. In matters we handle, we assess which channel is realistic given the seller's location, the account type, and the specific nature of the restriction before committing to a path.

What distinguishes a well-run EU dispute from a poorly run one? The seller who treats the process as purely an internal Amazon escalation – submitting a Plan of Action written entirely in Amazon's own framing, without reference to the regulatory rights at play – is working at a disadvantage. The seller who puts the platform on notice of its specific P2B and DSA obligations, sets out the deficiencies in the statement of reasons, and uses the formal complaint channel correctly is operating from a stronger position.

What Does the P2B Regulation Protect in Practice?

The P2B Regulation is narrower than the DSA in scope but in many ways more immediately useful for individual seller disputes, because it was drafted specifically for the business-user relationship.

The core protections are: a written, plain-language terms document; at least 15 days' notice before most changes to terms (shorter in some circumstances); a statement of reasons when an account or listing is restricted, suspended, or terminated; an internal complaint-handling system with a genuine response obligation; and access to mediation through mediators named in the terms.

The notice obligation is particularly important. The platform must tell you what it found, what rule it says you violated, and – importantly – give you a genuine opportunity to clarify the situation. If the restriction is later lifted following that clarification, the platform must tell you which specific input was decisive. This creates a record, and a record creates accountability.

We regularly see cases where a seller's account was restricted on automated grounds – a policy-match flag, an IP complaint trigger, a product-safety algorithm – and the restriction notice contained no real explanation. The P2B requirement is not met by a boilerplate notice. Building a formal response that identifies the gap in the notice, requests the specific factual basis, and uses the complaint channel as the vehicle for doing so is a different approach than the informal "contact seller support" route, and it produces a different kind of response from the platform.

The P2B Regulation also contains explicit rules about ranking. Platforms must disclose the main parameters that determine ranking for sellers' listings and the relative importance of those parameters. This matters in cases where a seller suspects a ranking penalty rather than a formal suspension – a quiet suppression that is harder to see and harder to challenge. The ranking-disclosure obligation gives a seller's counsel a hook to demand transparency.

How Does the DSA Change the Leverage for Sellers?

The DSA's seller-facing obligations build on P2B but go further in ways that matter operationally. Amazon as a VLOP faces requirements that a smaller platform does not, and those additional requirements translate into additional procedural rights for sellers on the receiving end of enforcement action.

First, the DSA requires that statements of reasons for content or account restrictions identify the specific ground relied on, whether automated tools were used, and what legal or contractual basis applies. If Amazon's enforcement was AI-driven – which a significant share of deactivations are – the DSA requires disclosure of that fact. A seller who knows the decision was automated knows immediately that there is no human analysis to push back on; the platform's process is the point of attack.

Second, the internal complaint system under the DSA must be accessible, free of charge, and produce a decision that is not merely a restatement of the original. In our practice, the quality of platforms' internal complaint responses has improved since VLOP designation – imperfectly, but meaningfully. A well-structured complaint filed through the correct channel, citing the DSA's requirements explicitly, does get a different quality of engagement than a generic appeal ticket.

Third, certified out-of-court dispute settlement (ODS) bodies give sellers a formal external route that does not require litigation. These bodies, certified by member state Digital Services Coordinators, can issue non-binding decisions on whether the platform's restriction was consistent with its terms and the DSA. The platform must engage in good faith. This is not arbitration – the outcome is not enforceable in the way an arbitral award is – but for many sellers it is a faster and cheaper route to a substantive review than court proceedings, and the platform's reputation with regulators creates a real incentive to comply.

What about the DMA? The DMA's gatekeeper obligations are enforced by the European Commission, not by individual sellers, and there is no direct private right of action under the DMA at the EU level (though some member states are developing complementary national routes). The DMA matters most as background context for cases involving systemic self-preferencing or discrimination – where the seller can demonstrate that the platform's conduct is part of a pattern that the Commission is already scrutinizing. In those cases, filing with the relevant Digital Services Coordinator or raising the issue through the European Commission's DMA enforcement channel can add weight to a negotiated resolution.

What Are the Real Decision Points – and the Trade-offs?

When a seller comes to us with an EU marketplace restriction, the first conversation is about the decision tree, not the paperwork.

If the restriction is a single-listing suspension citing a product-safety or IP ground, the immediate path is to identify whether the ground stated in the notice is factually supportable, build the counter-evidence (corrective documentation, test reports, authorization records, prior-use evidence), and use the internal complaint channel with a formal written submission that cites both the specific factual basis and the platform's P2B/DSA obligations. Timeline for a well-run single-listing complaint: several weeks in most cases, occasionally longer if the platform routes the complaint through a specialized review team. The operator reality is that inventory tied to a suspended ASIN is costing money every day – speed and precision in the initial submission matter more than volume.

If the restriction is an account-level suspension, the stakes are higher and the strategy is more differentiated. An account suspension may have a single root cause that a Plan of Action addresses, or it may reflect an automated enforcement decision that was never reviewed by a human. In the second case, the DSA's disclosure requirements become the lever: putting the platform on formal notice that the statement of reasons is insufficient and demanding a compliant response is sometimes more effective than filing a Plan of Action that implicitly accepts the platform's framing.

If internal routes have been exhausted – the initial appeal rejected, the formal complaint dismissed or responded to with a form letter – the ODS route or a regulatory complaint to the relevant Digital Services Coordinator is the next step. For a US seller trading into the EU, the practical question is which member state's DSC has jurisdiction; the answer usually tracks where Amazon's relevant EU entity is established and where the contract is governed. We work through that analysis case by case.

What if the issue is not a suspension but a systemic pattern – a ranking penalty, a Buy Box suppression, or a change in terms that reduces a seller's commercial position? These cases are harder to frame through the individual complaint process. The P2B ranking-disclosure obligation and the DMA's non-discrimination rules are the starting points. In practice, a formal demand letter setting out the specific P2B or DMA obligation the platform appears to be breaching, with a request for information and a deadline, sometimes produces a faster commercial resolution than a formal regulatory complaint – particularly where the seller has a significant commercial relationship with the platform.

A seller facing a product-safety suspension linked to the new GPSR requirements is in a distinct situation. The GPSR's responsible person requirement means that a non-EU seller must designate a responsible person established in the EU before their products can lawfully be made available on EU marketplaces. If Amazon restricts a listing because the required responsible person documentation is absent, that is a compliance gap, not a rights violation – and the correct path is to address the compliance gap, not to argue against the restriction. Distinguishing compliance remediation from genuine rights violations is a judgment call that affects both the strategy and the fee structure.

The GPSR and Product Safety: A Distinct Compliance Regime

Product safety is the fastest-growing category of EU marketplace suspension we see, and the GPSR – fully applicable from December 2024 – has changed the shape of these cases substantially.

The GPSR applies to all products made available to consumers in the EU, including through online marketplaces. It imposes obligations on manufacturers, importers, distributors, and – directly relevant to many Amazon sellers – fulfillment service providers. More importantly for marketplace sellers, it makes online marketplace operators responsible for ensuring that the economic operators using their platforms provide the required product documentation. Amazon, as the marketplace, will enforce GPSR compliance – and has been doing so through increasingly automated listing checks.

The responsible person requirement is the most operationally significant change for non-EU sellers. A product placed on the EU market must have a responsible person with an EU address whose name and contact details appear on the product or its packaging. Without a valid responsible person, a listing can be suspended, and the seller may face a compliance notice that requires remediation before any relisting is possible. This is not a gray area; it is a hard requirement of the regulation.

Beyond the responsible person, GPSR requires that products have a risk assessment, that certain categories of products include QR codes linking to safety information, and that serious risks are notified to the RAPEX/Safety Gate system. For sellers in categories like electronics, childrenswear, toys, furniture, and personal protective equipment, the documentation obligations are substantial and need to be embedded in sourcing and listing workflows, not treated as a one-off fix.

The intersection of GPSR with the DSA is worth noting. If Amazon restricts a listing on GPSR grounds and the statement of reasons does not identify the specific GPSR provision allegedly violated or the specific product documentation found to be deficient, the seller has a P2B/DSA argument about the quality of the notice even as they address the underlying compliance issue. Both tracks can run simultaneously.

Extended Producer Responsibility and the Hidden Compliance Cost

Extended Producer Responsibility (EPR) requirements – principally for packaging, electrical and electronic equipment, and batteries – are a separate layer of EU compliance obligation that has generated a growing number of marketplace suspensions, particularly for sellers who listed into the EU market without establishing the required national producer registrations.

EPR rules are national in implementation even when derived from EU directives. Germany's LUCID packaging register and its ElektroG/WEEE register are the most visible examples, but every major EU member state has its own EPR regime for each covered category. Amazon, as part of its GPSR and broader product-safety compliance push, has tightened its requirements for EPR registration documentation across its EU storefronts.

A seller who lists batteries, electronics, or packaged goods in Germany without the required LUCID and relevant EPR registrations risks both listing restriction and, in principle, administrative penalties from national enforcement authorities. The marketplace suspension is the most immediate commercial problem, but it is a symptom of the underlying compliance gap. In matters we handle involving EPR-based restrictions, the work has two stages: documenting and remedying the compliance gap, then using the P2B/DSA complaint channel to challenge any restriction that was not accompanied by an adequate statement of reasons.

Bundeskartellamt, DMA, and Systemic Competition Concerns

For sellers facing what looks less like an individual enforcement action and more like a systematic disadvantage – consistent Buy Box suppression, discriminatory ranking, or terms changes that appear designed to benefit Amazon's own retail offers – the competition-law dimension of EU marketplace regulation becomes relevant.

The Bundeskartellamt, Germany's Federal Cartel Office, has been among the most active national competition authorities in relation to Amazon. Under Section 19a of the German Competition Act (Gesetz gegen Wettbewerbsbeschränkungen), the Bundeskartellamt has designated Amazon as a company of paramount significance for competition across markets, allowing it to prohibit specific practices without requiring a finding of abuse of dominance in the traditional sense. Proceedings and outcomes in those cases are matters of public record, but specific case outcomes from those proceedings should not be read as guarantees of any individual outcome.

The DMA sits alongside national competition law. Where a seller can document a specific self-preferencing or discrimination pattern, a complaint to the European Commission's DMA enforcement channel is one option – though the Commission's process is aimed at systemic infringement and does not produce individual remedies quickly. In practice, the most effective route for an individual seller with a competition-adjacent complaint is often a formal demand letter citing the specific DMA or P2B provision, combined with a complaint to the national Digital Services Coordinator, while keeping the regulatory avenue open as leverage for negotiation.

We regularly advise sellers on whether their situation involves a genuine competition-law angle or is better framed as a standard P2B/DSA complaint. The distinction matters because the strategies, timelines, and fee structures are different. Committing to a competition-law track when a well-drafted DSA complaint would have resolved the issue faster and cheaper is a costly mistake – and one that we see sellers make when they are advised by generalist counsel without specific marketplace-regulation experience.

Micro-Cases: How These Issues Arise in Practice

A kitchenware brand selling into Amazon.de and Amazon.fr came to us in fall 2025 after receiving account-level restriction notices on both storefronts simultaneously. The stated ground was product-safety non-compliance. The notices identified no specific product, no specific standard, and no specific documentation deficiency – simply a reference to Amazon's general product-safety policy. We built the formal complaint using the P2B statement-of-reasons deficiency as the initial lever, demanded the specific factual basis for the restriction, and simultaneously ran a GPSR compliance audit. The audit identified one category of products that did require remediation; the majority were compliant. The formal complaint produced a substantive response from Amazon's specialized compliance team; after the remediation documentation was submitted for the affected category and the complaint record was complete, the restriction was lifted for the compliant product lines.

A US-based electronics distributor selling into several EU storefronts came to us in spring 2026 after a listing suppression that did not come with a formal restriction notice – the listings simply stopped appearing in search results across Amazon.co.uk and Amazon.de. No appeal notification had been issued. We framed the matter as a ranking-restriction under the P2B Regulation's ranking-transparency provisions, demanded the specific parameters relied on, and filed a formal internal complaint. The platform's response identified an automated policy flag linked to EPR registration documentation the distributor had submitted but that had not been processed correctly in Amazon's system. Once the documentation processing error was corrected, the listings restored. The key in that case was not the appeal itself but correctly identifying that the issue was a documentation processing failure, not a substantive compliance failure – two different problems requiring two different responses.

Common Mistakes Sellers Make Without Specialist Representation

The myth that EU sellers have no leverage once a platform suspends them is the single most costly misconception in this practice area. Sellers who accept that framing typically take one of two wrong paths: they either abandon the account or they submit a generic appeal that does not engage the regulatory rights at all.

The generic Plan of Action problem is real. A POA written in Amazon's own content format – root cause, corrective actions, preventive measures – is the right tool for a performance or policy deactivation on the US platform. It is not the right tool, or not the only tool, for an EU restriction where the statement of reasons itself is deficient. Using a US-style POA for an EU DSA-governed restriction is like responding to a court filing with a letter – the format signals that the sender does not understand the proceeding they are in.

The second common mistake is missing the formal complaint channel. Most sellers who appeal an EU restriction do so through Seller Central's standard appeal interface. That interface may satisfy the internal complaint obligation technically, but it does not put the platform on formal notice of its P2B/DSA obligations. A formal written complaint, submitted through the designated channel and explicitly invoking the seller's rights under the applicable regulation, creates a record that the informal route does not. The platform's response obligation is higher. The quality of the response is, in our experience, typically better.

The third mistake is conflating compliance remediation with rights vindication. If the platform's restriction has a legitimate basis in a genuine compliance gap – a missing GPSR responsible person, an absent EPR registration – the correct response is to fix the compliance gap, not to argue that the restriction was unlawful. Arguing the wrong track wastes time and damages credibility with the platform's compliance team. Conversely, if the restriction has no basis in a genuine compliance gap and the platform's statement of reasons is deficient, accepting the restriction as legitimate and rushing to "fix" something that is not broken is an equally costly error.

What does handling this correctly require? At minimum: a careful read of the notice against the actual regulatory requirements, a parallel compliance audit, a decision on whether the complaint track, the remediation track, or both tracks should run simultaneously, and a formal submission that is calibrated to the specific regulatory instrument involved. That is the scoping work we do at the start of every EU matter.

Seller Decision Points: a Practical Decision Map

The choice of path in an EU marketplace matter depends on three variables: the type of restriction (listing-level vs account-level), the stated ground (policy, product-safety, IP, or unexplained), and the history of the account and the seller's EU compliance posture.

If the notice cites a specific product-safety standard and there is a genuine documentation gap, the route is GPSR or EPR remediation combined with a formal complaint challenging the adequacy of the notice, on a timeline of several weeks to a few months depending on the complexity of the documentation. If the notice cites an IP complaint and the seller has authorization or prior-use evidence, the route is a counter-notice and formal complaint, on a faster timeline if the evidence is ready. If the notice is essentially unexplained or cites a generic policy reference, the route is a formal P2B/DSA complaint challenging the statement-of-reasons deficiency, with a demand for the specific factual basis, before filing any substantive response on the merits.

If a first formal complaint was submitted and received a form-letter response, the route is either a second escalation within the internal system identifying specifically how the response failed to meet the DSA's requirements, or a referral to an ODS body, or both. If the ODS route has been exhausted or is not available for the specific matter, a regulatory complaint to the Digital Services Coordinator is the remaining formal channel before litigation. In matters involving a US seller trading into the EU without an EU establishment, we work with appropriate local counsel to ensure the formal complaint is filed correctly in the relevant jurisdiction.

A brief note on fees: EU marketplace matters at Tutamen begin with a fixed scoping review, which identifies the applicable instruments, the account's compliance posture, and the realistic path. Ongoing representation is quoted as a fixed fee after the scoping review, so the seller knows the cost before committing to the next stage. There are no open-ended retainers and no surprises.

Frequently Asked Questions

How long does resolving EU marketplace regulation usually take on Amazon US?

The timeline depends on the type of restriction and the route taken. A single-listing complaint where the factual basis is clear and the evidence is ready typically takes several weeks. An account-level suspension involving a compliance audit alongside a formal DSA complaint usually takes longer – a matter of months in most cases. Where the internal complaint process produces a deficient response and the matter moves to an ODS body or Digital Services Coordinator, the timeline extends further. What consistently shortens the timeline is the quality and precision of the initial formal complaint: a submission that identifies the specific regulatory deficiency, provides the relevant evidence, and puts the platform on notice of its obligations draws a substantive response faster than a generic appeal.

What are the main risks if I handle EU marketplace regulation alone?

The most common risk is using the wrong procedural tool. Sellers who submit a US-style Plan of Action for an EU regulatory restriction miss the formal complaint channel entirely, which means they generate no record of the platform's failure to comply with its P2B or DSA obligations. A second risk is conflating compliance remediation with rights vindication – accepting a restriction as legitimate and attempting to fix a compliance gap that does not exist, while the actual problem (a deficient statement of reasons or an automated decision with no human review) goes unchallenged. A third risk is missing time-sensitive steps: the P2B Regulation's notice periods, the DSA's complaint timelines, and the window for ODS referral all have procedural implications.

Do I need a lawyer for EU marketplace regulation?

Not every EU marketplace restriction requires legal representation. If the issue is a straightforward documentation gap – a missing responsible person under GPSR or an absent EPR registration – the seller may be able to remediate and appeal without specialist help, provided they identify the correct compliance standard and submit the right documentation. Legal representation becomes important when the restriction is not explained adequately, when the internal complaint process has already produced a deficient response, when there is a systemic pattern suggesting DMA or P2B ranking-disclosure issues, or when the matter involves multiple EU storefronts or a dispute over whether the restriction was lawful in the first place. At minimum, a one-time scoping review by specialist counsel – to identify the applicable instruments and the realistic options – is almost always worthwhile before committing to a response strategy.
