Bundeskartellamt proceedings and sellers: the current state for sellers

German competition law is reshaping how Amazon operates across Europe. The Bundeskartellamt – Germany's Federal Cartel Office – has applied its extended abuse-control powers to platforms with paramount cross-market significance, and the downstream effects land directly on individual sellers. If you sell on Amazon ES or any other European Amazon surface and have seen unexplained listing changes, margin pressure from platform rules, or a suspension notice that reads like a compliance measure, you may already be inside the blast radius of those proceedings. Understanding what is happening, and why, is the starting point for any practical response.

TL;DRBundeskartellamt proceedings against Amazon concern the platform's treatment of third-party sellers under German competition law – specifically the authority's power to prohibit conduct by platforms with paramount cross-market significance. For sellers, the proceedings matter because they can constrain Amazon's ability to suspend, delist, or impose one-sided conditions without adequate justification or a fair internal-complaint path. Sellers on Amazon ES and other EU surfaces gain indirect protection: the rulings and commitments negotiated at the platform level set the floor for what Amazon must offer to every seller who can invoke them.

This briefing covers three things: what the proceedings actually mean at the account level, the realistic procedural path a seller can use alongside or after those proceedings, and the decision points that determine whether a seller should act alone or bring in specialist counsel. We also address the P2B Regulation, the Digital Services Act (DSA), and the Digital Markets Act (DMA) – because those instruments interact with Bundeskartellamt outcomes in ways that either expand or limit a seller's options depending on which surface and which country is involved.

What does the Bundeskartellamt's role actually mean for a marketplace seller?

The Bundeskartellamt's extended powers under German competition law allow it to prohibit specific conduct by platforms before that conduct causes lasting market harm. For Amazon, the authority has examined practices including parity obligations, the relationship between first-party retail and third-party selling conditions, Buy Box allocation, and the terms on which sellers access Prime-eligible logistics. The proceedings are formal: Amazon operates as a respondent, the authority issues findings, and the platform either commits to changes or faces binding orders.

In matters we handle, sellers often discover the practical effects only after a problem has already occurred on their account. A listing suppression that arrives with a reference to "policy compliance" may have its roots in a platform-level commitment Amazon made to the Bundeskartellamt – a commitment that changes what Amazon can and cannot do, and what you are owed as a result. That gap between the platform's regulatory obligations and what actually shows up in a suspension notice is where most of the dispute work sits.

The proceedings do not give sellers a direct enforcement right in the sense that you cannot file a complaint with the Bundeskartellamt about your own account suspension and expect a personal ruling. What the proceedings do is generate a legal and factual record of what Amazon agreed to change, and that record becomes a foundation for: internal-complaint claims under the platform's own procedures, P2B Regulation complaints, DSA transparency claims, and – in serious cases – civil proceedings in German courts or arbitration under the dispute-resolution mechanism applicable to your account.

For Amazon ES sellers specifically, the wrinkle is jurisdiction. Amazon's Spanish marketplace operates under Amazon Services Europe SARL, a Luxembourg-incorporated entity. German competition law applies to Amazon's conduct in the German market, but the commitments Amazon has given to the Bundeskartellamt are structural – they apply to how the platform operates, and therefore they affect seller treatment across the EU surfaces in practice. Whether a specific commitment is enforceable in Spain requires a separate analysis, which is one reason cross-border EU marketplace disputes benefit from counsel who can read across the regulatory instruments rather than stopping at one country's law.

How the P2B Regulation, the DSA, and the DMA change the seller's position

Three EU-level instruments now run alongside Bundeskartellamt proceedings and, together, they give sellers more procedural traction than existed a few years ago. Understanding which instrument applies to your situation – and in which order – is the first practical task in any EU enforcement matter.

The Platform-to-Business (P2B) Regulation is the most immediately useful for most sellers. It requires platforms to provide a written statement of reasons for any suspension, delisting, or material restriction of service. A suspension notice that says only "policy violation" or that directs a seller to a help page is almost certainly non-compliant with the P2B requirements. The seller's right is to receive a particularized explanation – a right that has teeth because the platform's own complaint-handling system must address it.

The Digital Services Act (DSA) applies to Amazon as a Very Large Online Platform (VLOP). The DSA's relevance to individual sellers is primarily procedural: sellers can use the DSA's statement-of-reasons mechanism and the internal complaint-handling system to demand substantive review of a suspension decision. In our experience handling EU suspension matters, the DSA's complaint path is most powerful when used in combination with the P2B Regulation – the seller invokes both simultaneously to force a documented, reasoned review rather than the boilerplate denial that often comes from a standard appeal.

The Digital Markets Act (DMA) applies to Amazon as a designated gatekeeper. The DMA's obligations are primarily about interoperability, data access, and self-preferencing – they are not a direct suspension-appeal tool. But where a seller's suspension appears to be connected to the platform's self-preferencing conduct (for example, a seller whose listings were suppressed in favor of Amazon's own retail arm), the DMA creates a regulatory record and a European Commission enforcement track that can be referenced in parallel private proceedings.

The interaction between Bundeskartellamt commitments and these EU instruments is not automatic. A seller on Amazon ES who experiences a suspension cannot simply write to the Bundeskartellamt and cite the DMA and expect a coordinated response. The instruments require activation – a formal invocation through the right procedural channels, in the right sequence, with the right supporting documentation. We regularly see sellers lose procedural ground by filing an informal email complaint when what was needed was a formal P2B statement-of-reasons request that would have reset the platform's internal deadline.

For a full account of how EU-level instruments interact, the EU marketplace regulation complete guide for sellers sets out each instrument's scope, the procedural steps, and the common failure points in more detail than is possible in this briefing.

Who is affected and how does an Amazon ES seller know if the proceedings are relevant to their situation?

Not every Amazon ES suspension or listing problem is connected to Bundeskartellamt proceedings. The relevance test is whether the conduct you experienced – the suspension reason, the restriction type, the platform explanation you received – maps onto the categories of conduct the Bundeskartellamt has examined.

The sellers most likely to have a claim that overlaps with Bundeskartellamt territory are those who have experienced one or more of the following: a suspension or delisting accompanied by a vague or standardized reason that does not identify specific conduct; a change in Buy Box eligibility or Prime status that arrived without advance notice or explanation; a condition imposed on continued selling that appeared to cross-subsidize Amazon's own first-party retail position; or a refusal of access to the platform's internal-complaint system or a non-substantive response to a complaint.

Amazon ES sellers should also be aware that the platform's obligations under the P2B Regulation and the DSA apply to them regardless of the Bundeskartellamt proceedings. Those are EU-wide instruments. A seller on Amazon ES has procedural rights under EU law that exist independent of what the German authority has or has not decided. The Bundeskartellamt proceedings add weight and context to those claims – they do not create them from scratch.

In matters we handle involving EU marketplace suspensions, the initial review looks at three things: the suspension notice text and whether it meets P2B standards; the account history and whether there is a pattern that suggests structural platform conduct rather than an isolated policy enforcement decision; and the applicable BSA version and dispute-resolution path to confirm which instruments are actually available for that account. That review is the first step before any filing.

What is the realistic procedural path for a seller who has been suspended or restricted?

The procedural path for a seller on Amazon ES who believes their suspension or restriction is connected to, or contradicts, Amazon's regulatory obligations under EU law or Bundeskartellamt commitments runs in a defined sequence. Skipping steps or conflating them is the most common mistake.

Step one is the formal P2B statement-of-reasons request. If the suspension notice you received does not provide a particularized reason for the specific conduct at issue, you are entitled to request one. This request should be in writing, cite the P2B Regulation by name, and identify the specific decision you are challenging. The platform is required to respond to a formal complaint within the its internal-complaint framework. The response – or a failure to respond substantively – becomes evidence for every subsequent step.

Step two is the internal-complaint process under the DSA and the platform's own stated terms. This is not the same as submitting a standard Seller Central appeal. It is a formal invocation of the platform's complaint-handling obligation as a VLOP under the DSA. The distinction matters because a DSA complaint creates a documented record that a regulator can examine, whereas a Seller Central appeal is an informal submission that leaves no comparable trace.

Step three – if the internal path does not produce a substantive outcome – is the decision on external remedies. Those remedies include the dispute-resolution mechanism in the BSA (whose precise terms depend on the version of the agreement applicable to the account, which we check first), civil proceedings in the competent EU court, or – for conduct that is structural and affects multiple sellers – a complaint to the competent national regulator or to the European Commission under the DMA.

The timeline across these steps is not short. Internal-complaint procedures can take several weeks. External proceedings, including arbitration or civil litigation, typically take considerably longer. The seller's cash flow and inventory position during that period is a real consideration, and it shapes the strategic choice between pressing the internal path harder versus moving to external remedies sooner. We work to identify the fastest viable route for each situation, not the theoretically correct one in the abstract.

For sellers who have already gone through one round of the internal process and received a rejection, the picture changes. A first rejection does not close the path – it narrows it. The key is identifying why the first submission failed and whether the reason given was substantive or procedural. If it was procedural – the wrong format, the wrong channel, an incomplete statement – the fix may be straightforward. If it was substantive – the platform claiming the conduct was justified – the external remedies become more relevant. The step-by-step process for appealing a delisting on EU-registered accounts is covered in detail in the guide to appealing an EU delisting, step by step.

One micro-case from our practice illustrates the sequencing point. An electronics accessories seller on Amazon DE (winter 2025) came to us after a listing restriction had been imposed without a written reason and a standard help-center appeal had produced an automated response. We filed a formal P2B statement-of-reasons request, which forced a written explanation within the required timeframe. The explanation revealed the restriction was tied to a pricing-parity mechanism that Amazon had, in fact, already committed to modify as part of its Bundeskartellamt undertakings. We used that gap – between what the platform committed to do and what it had actually done to this seller's account – to build the internal-complaint case, and the restriction was lifted. The entire process, from first filing to resolution, took several weeks, not months.

What are the seller's decision points and trade-offs?

The myth that EU sellers have no leverage once a platform suspends them is precisely that – a myth. The regulatory infrastructure now in place gives sellers more procedural tools than at any previous point. The question is not whether tools exist, but which tool fits the specific situation and at what cost in time, money, and management attention.

The first decision point is timing. EU regulatory procedures have deadlines that are not always obvious from the suspension notice. A failure to invoke the P2B complaint path promptly does not extinguish the right, but it weakens the procedural record and makes the argument that the platform's conduct was ongoing harder to sustain. Sellers who wait to see if the account "fixes itself" before engaging specialist help consistently arrive with a thinner record than those who act quickly.

The second decision point is scope. A suspension that affects a single ASIN or a narrow product category is a different matter from a wholesale account deactivation or a structural change to Buy Box or Prime eligibility. The first may be resolved efficiently through the internal-complaint path alone. The second may require parallel tracks – internal complaint, P2B request, and a parallel assessment of whether the DMA or Bundeskartellamt-derived arguments add weight.

The third decision point is the BSA dispute-resolution path. The path depends on the BSA version that applies to the account, which we check first. For sellers on Amazon ES, the applicable BSA may be the EU version governed by Luxembourg law, and the dispute-resolution terms in that version differ from those in Amazon's US BSA. Whether arbitration, a Notice of Dispute, a pre-arbitration demand, or direct civil litigation is the right external tool requires reading the specific agreement applicable to the account before advising on the external route.

If you are facing a situation where the internal path has stalled and the external options feel unclear, the honest answer is that a single review call with counsel familiar with both EU marketplace regulation and the specific platform's BSA terms will tell you more than several weeks of working through Seller Central alone. The cost of that review is a fixed fee quoted up front. The cost of a misstep at the P2B or DSA stage – particularly filing in the wrong format or channel – can be weeks of procedural restart.

The difference between how enforcement plays out in EU jurisdictions versus the US is also relevant for sellers who operate on multiple surfaces. The divergence in approach, timelines, and available remedies is covered in the cross-surface analysis on why EU versus US enforcement differences happen and how sellers respond.

A second illustration from recent matters: a fashion brand selling on both Amazon ES and Amazon IT (spring 2026) came to us after a simultaneous account-level restriction appeared on both surfaces, citing unspecified "compliance requirements." The restriction affected their entire catalog, not individual listings, which signaled a structural platform decision rather than a product-level enforcement action. We built the statement-of-reasons case under the P2B Regulation across both surfaces simultaneously, mapped the restriction against the relevant Bundeskartellamt commitment record to identify where the platform's stated justification was inconsistent with its regulatory undertakings, and filed a formal DSA internal complaint. The restriction on Amazon ES was lifted; the Amazon IT path required a further round of the internal process and took longer, illustrating that even on closely related EU surfaces, the procedural pace is not uniform.

What is still uncertain and what sellers should watch

Several aspects of the regulatory picture remain genuinely unsettled, and sellers who rely on fixed interpretations risk building their strategy on a foundation that shifts.

The interaction between Bundeskartellamt commitments and the DMA's enforcement track is still being worked out. The European Commission has primary enforcement jurisdiction for DMA gatekeeper obligations, and the relationship between national competition-authority proceedings (like the Bundeskartellamt's) and Commission DMA proceedings is not yet settled by practice. A commitment Amazon gave to the Bundeskartellamt does not automatically satisfy a DMA obligation, and a DMA finding does not automatically revive or reinforce a Bundeskartellamt commitment. Sellers should treat these as parallel but distinct instruments.

The scope of private enforcement – the ability of an individual seller to bring a civil claim in an EU court based on a breach of a commitment made in Bundeskartellamt proceedings – varies by jurisdiction and is an active area of legal development in Germany and at the EU level. The question of whether a seller on Amazon ES can bring that kind of claim in a Spanish court, based on conduct governed by German competition-law commitments, involves a choice-of-law analysis that is not settled.

The DSA's VLOP enforcement track is operational but still maturing. The European Commission has begun formal proceedings against designated VLOPs, and the outcome of those proceedings will clarify the DSA's practical scope for sellers. In the meantime, sellers should use the DSA's internal-complaint mechanism as a procedural tool while treating Commission-level enforcement as background rather than a primary remedy for individual account disputes.

Finally, the P2B Regulation's penalty and enforcement regime differs across EU member states. Spain has its own enforcement authority for P2B compliance, and the intensity of enforcement has varied. Sellers on Amazon ES should be aware that a P2B complaint may need to be addressed to the Spanish authority if the internal-complaint path does not yield a substantive result, and that the Spanish authority's approach may differ from those of authorities in Germany, France, or Italy.

Frequently asked questions

How long does resolving bundeskartellamt proceedings and sellers usually take on Amazon ES?

Timelines vary considerably depending on which procedural track is used. A P2B statement-of-reasons request and the internal-complaint process typically move through their initial phase within several weeks. If the matter requires escalation to external dispute resolution – whether arbitration under the applicable BSA terms, a civil claim, or a regulatory complaint to the Spanish P2B enforcement authority – the timeline extends materially. Sellers should plan for several months on contested external matters and use the internal track first to test whether a faster resolution is possible. The specific facts of the account, the suspension reason given, and the quality of the documentation supporting the complaint all affect pace.

What are the main risks if I handle bundeskartellamt proceedings and sellers alone?

The primary risks are procedural. EU marketplace regulation involves multiple instruments – the P2B Regulation, the DSA, the DMA, and any applicable Bundeskartellamt commitment record – that must be invoked in the right format, through the right channel, and in the right sequence. A seller who files a DSA complaint in the wrong forum, or who submits a P2B request that is addressed to the wrong entity, may lose weeks to procedural restart. The second risk is substantive: without visibility into the specific Bundeskartellamt commitments Amazon has made, a seller cannot identify when the platform's stated reason for a suspension is inconsistent with its regulatory undertakings, which is often the most powerful argument available.

Do I need a lawyer for bundeskartellamt proceedings and sellers?

Not every situation requires counsel. A seller whose listing suspension comes with a clear P2B-compliant reason and who simply needs to correct an identified product issue may be able to manage the internal-complaint path without legal help. Where specialist counsel adds clear value is when: the suspension reason is vague, structural, or appears to conflict with EU regulatory obligations; a first-round appeal has been rejected; the matter involves cross-surface restrictions or impacts on the entire catalog; or the seller is considering external remedies. An attorney-led review at the outset costs less than fixing a misstep later, and the fee is fixed and quoted up front after a short review of the relevant documents.
