What to know about internal complaint-handling under the DSA

TL;DRInternal complaint-handling under the Digital Services Act (DSA) is the formal mechanism that gives sellers on Very Large Online Platforms – including Amazon FR – the right to challenge a platform's content-moderation or suspension decision through an internal review process before pursuing any external route. The DSA requires these platforms to operate an accessible, timely, and reasoned complaint system. For a seller facing a listing removal or account restriction on Amazon FR, that system is the first procedural step, and how it is used shapes every option that follows.

On paper, the DSA's complaint rules look like a straightforward path: submit a complaint, receive a reasoned decision, move on. In practice, the system involves procedural conditions, specific evidentiary requirements, and downstream consequences that most sellers encounter for the first time when their account is already at risk. This FAQ hub answers the questions we consistently hear from Amazon FR sellers who have just received a deactivation notice or a statement of reasons and do not yet know what their rights actually are.

The sections below cover: what the internal complaint-handling mechanism actually is and what the DSA requires of Amazon; how the process unfolds on Amazon FR in practice; what a seller must prepare before filing; the decision points and trade-offs between the internal route, the Platform-to-Business Regulation (P2B), and the Digital Markets Act (DMA); and what to do if the complaint comes back rejected. A short FAQ addresses the three questions sellers ask most often.

What is internal complaint-handling under the DSA, and what does it require of Amazon FR?

The DSA's internal complaint-handling obligation requires Amazon, as a Very Large Online Platform (VLOP), to give any seller who receives a restriction notice a clear path to challenge that decision internally before resorting to external mechanisms. The obligation is not optional. Under the DSA, a VLOP must maintain a free, electronic, and easily accessible system for complaints against decisions to restrict access to, or remove, content or services. Amazon FR is subject to those requirements because of its designation as a VLOP under the DSA regime.

What does that mean concretely? When Amazon FR issues a statement of reasons – the formal document that must accompany any content-moderation or suspension decision under the DSA – it must also tell the seller that an internal complaint mechanism exists and how to reach it. The statement of reasons itself is a DSA requirement: it must identify the legal or contractual ground for the decision, describe the facts and circumstances relied on, and indicate what redress options are available. A suspension notice that omits that information is not compliant with the DSA, and that gap is itself a basis for challenging the restriction.

In our practice, we regularly see statements of reasons on Amazon FR that satisfy the form of the DSA requirement but are thin on substantive reasoning. The platform names a policy category – inauthentic goods, or a safety concern, or an IP complaint – but does not connect the stated facts to the seller's specific account history or product listing. That gap matters. An internal complaint that identifies the reasoning failure directly, and supplies the evidence the platform's original review did not have, is structurally stronger than a generic appeal. The internal complaint mechanism is not an automatic second refusal. It is an obligation the platform must take seriously, and a well-framed complaint can and does change outcomes.

The DSA also creates accountability for how the complaint is handled. The platform must process the complaint without undue delay and must give a substantiated statement of reasons for its decision on the complaint. That creates a written record – and a record the seller can later use in a P2B mediation, a DMA-based complaint, or a broader regulatory escalation. For the full background on how EU marketplace law shapes these obligations, see our EU marketplace regulation guide for sellers.

How does the internal complaint process actually unfold on Amazon FR?

The process begins with the statement of reasons, which Amazon FR is required to issue when it takes a content-moderation or suspension action. The seller then has the right to submit a complaint through the platform's internal mechanism – in practice, this typically means a structured submission through Seller Central or a designated appeals channel, depending on the nature of the restriction. The complaint must identify the specific decision being challenged, the ground for the challenge, and any supporting evidence.

Timing matters here. The DSA does not set a fixed deadline for the seller to lodge a complaint, but the Platform-to-Business Regulation imposes its own obligations, and Amazon's terms reflect both sets of rules. Acting quickly is important for a separate reason: the longer a listing is down or an account is restricted, the more inventory cycles, disbursement windows, and customer relationships are affected. In matters we handle involving Amazon FR, the practical pressure is almost always the same – the seller's cash flow does not pause while the platform works through its internal review.

Once the complaint is submitted, Amazon FR's internal system is required to process it without undue delay. The DSA does not define "undue delay" as a number of calendar days, and in our experience the actual review period varies with the complexity of the underlying issue and the queue of matters the platform is managing. What the DSA does require is a substantiated decision at the end of that process – not a template response, and not a bare confirmation of the original decision without reasoning.

If the internal complaint resolves the restriction, the process ends there. If it does not – if the complaint is rejected, or if the platform's response is inadequate – the seller is not out of options. The DSA creates a pathway to out-of-court dispute resolution through certified DSA dispute settlement bodies. Separately, the P2B Regulation's own dispute-resolution mechanism may apply. And for broader systemic issues with how Amazon FR operates, the DMA's gatekeeper obligations are a distinct but complementary tool. The P2B dispute resolution mechanism is addressed in detail in our dedicated guide.

What must a seller prepare before filing an internal complaint on Amazon FR?

A well-prepared internal complaint does several things at once: it responds to the specific reasoning in the statement of reasons; it supplies the evidence the platform's automated or first-level review did not have; and it creates a clear record for any escalation that follows. Preparing that complaint requires working backward from the statement of reasons itself.

The first step is to read the statement of reasons with care. What is the stated ground for the restriction? Is it a policy category – safety, IP, authenticity – or a contractual provision? Does the stated ground match the actual facts of the listing or the account? In many matters we work on, the statement of reasons names a category but does not actually apply it correctly to what the seller was doing. That mismatch is the core of the complaint.

Evidence to gather before filing typically includes:

• The original statement of reasons and any associated notice from Amazon FR, in full
• Supplier invoices, authorization letters, or chain-of-custody documentation for the products at issue
• Any prior correspondence with Amazon FR about the same listing or account issue
• Product safety documentation, CE declarations, or test reports if the restriction cites a safety ground
• A clear account timeline showing that the restriction arises from a specific event, not a pattern of conduct
• Screenshots and records of the affected listings at the time of restriction

What a seller should not do is submit the same evidence the platform already reviewed, without any additional argument or framing, and expect a different outcome. The internal complaint mechanism is an opportunity to provide new reasoning or evidence. If the complaint simply repeats the seller's original listing information, the platform has no new basis on which to change its decision. The complaint must identify specifically what the platform got wrong and supply the material that corrects it.

An error we regularly see in matters that come to us after a rejected first complaint: the seller addressed the policy category instead of the statement of reasons. The platform cited, say, a product safety concern and referenced a particular category of documentation. The seller responded with general product information rather than the specific safety documentation the platform identified as missing. The internal complaint process rewards precision, not volume.

What are the decision points and trade-offs between the internal route, P2B, and the DMA?

A seller on Amazon FR facing a restriction under EU rules has several procedural tools available. Choosing between them – and in what order – is one of the first strategic questions we work through with sellers, because the choices are not mutually exclusive but they do affect each other.

The internal complaint route under the DSA is the starting point in most situations. It is free, it is fast relative to external escalation, and it creates the written record on which all later routes depend. If the internal complaint succeeds, the other routes become moot. If it fails, the platform's substantiated rejection decision becomes a document the seller can use in a P2B mediation or DSA dispute-settlement proceeding to show that the internal route was genuinely exhausted.

The P2B Regulation adds a separate layer. Under the P2B rules, Amazon FR is required to offer sellers access to mediation through an independent mediator for disputes about access to the platform. The P2B mediation route is not dependent on the DSA internal complaint process – a seller can in principle pursue both – but in practice the internal complaint record strengthens the P2B case considerably. If the complaint reveals that the platform's reasoning was internally inconsistent, or that the statement of reasons omitted material facts, that inconsistency becomes the center of the P2B submission. Our guide on P2B dispute resolution for marketplace sellers sets out how that mechanism operates.

The DMA's gatekeeper obligations are a third dimension, relevant where the restriction on Amazon FR relates to how the platform uses data, preferential ranking, or access to its core platform services. The DMA does not give individual sellers a direct complaint right in the same way the DSA does, but it creates obligations on Amazon as a gatekeeper that a seller's lawyer can reference in a regulatory complaint or in communications with the European Commission or a National Competent Authority. For sellers whose restriction follows a pattern affecting a category or a class of third-party sellers, a DMA-based escalation is worth evaluating alongside the internal route.

The decision between routes also depends on commercial timing. Internal complaints can resolve quickly. P2B mediation typically takes longer. Regulatory escalation is a multi-month process at minimum. A seller whose inventory is tied up pending a disbursement or whose listings are generating zero revenue needs a triage judgment – which route is most likely to restore trading quickly, and which routes build the long-term record in parallel. That triage is where legal advice on EU marketplace regulation adds the most immediate value. For a practical account of how a P2B suspension was resolved, see how one seller resolved a P2B regulation notice of suspension.

What happens if the internal complaint is rejected, or if Amazon FR's response is inadequate?

A rejected internal complaint is not the end of the road. Under the DSA, a seller who has used the internal complaint mechanism and received a substantiated rejection can access out-of-court dispute settlement through a certified DSA dispute settlement body. Those bodies are independent, certified by the Digital Services Coordinator of the relevant member state, and able to resolve disputes about the platform's decision. Amazon FR, as a VLOP, is required to engage with a certified settlement body in good faith and to bear a reasonable share of the costs.

What makes a post-rejection escalation viable? The quality of the internal complaint record. If the complaint clearly identified the error in the statement of reasons, supplied corrective evidence, and the platform's rejection failed to engage with that evidence, the seller has a strong basis for arguing before a settlement body that the internal process was not conducted in good faith. Conversely, a thin complaint that only restated the seller's original position gives a settlement body less to work with.

There is also the question of what "inadequate" means. The DSA requires the platform's response to the internal complaint to be substantiated. A template response that confirms the original decision without any engagement with the specific arguments raised in the complaint is arguably non-compliant with that requirement. Flagging that deficiency directly – in a follow-up submission or in the settlement-body filing – is a separate basis for challenge that does not depend on the merits of the underlying suspension decision.

In matters involving Amazon FR sellers who came to us after a rejected first complaint, the most common problem was that the complaint itself was not built around the statement of reasons. Once that was corrected – refiling with a complaint that tracked the platform's stated reasoning point by point and addressed each gap – the outcome was frequently different. A rejected internal complaint, properly diagnosed, is often a filing problem rather than a substantive problem with the seller's position.

Where the restriction involves a related issue under P2B or DMA rules, those tracks can run in parallel with the DSA escalation. The legal and procedural relationship between the three regimes is not always intuitive, and the seller's goal – restoring access, recovering disbursements, protecting the account long-term – may be best served by a coordinated approach rather than a sequential one.

FAQ: What sellers ask most about internal complaint-handling under the DSA

How long does resolving internal complaint-handling under the DSA usually take on Amazon FR?

There is no fixed statutory deadline that applies to every case. The DSA requires Amazon FR to act without undue delay, but what that means in calendar terms depends on the complexity of the matter, the evidence submitted, and the platform's current review capacity. In our practice, straightforward complaints with complete supporting evidence can move through the internal review process in a matter of weeks. More complex matters – those involving multiple products, underlying IP disputes, or safety documentation issues – take longer. The important point is that filing a complete, well-framed complaint from the start reduces the likelihood of requests for further information that extend the timeline. Sellers should not assume that filing quickly with incomplete evidence is better than filing carefully with a complete submission. A second round of requests adds delay, not speed.

What are the main risks if I handle internal complaint-handling under the DSA alone?

The primary risk is creating a weak record that limits what is possible in later escalation. The internal complaint is not a form-filling exercise. It is a legal submission that the platform evaluates against specific DSA and P2B obligations – and that a DSA dispute settlement body will later examine if the complaint is rejected. A complaint that does not track the statement of reasons, that fails to identify the platform's specific reasoning error, or that supplies general documentation instead of targeted evidence may be technically complete but is unlikely to succeed. There is also the risk of waiving procedural options inadvertently. If a complaint is framed in a way that concedes facts that are actually in dispute, or that misidentifies the ground for challenge, correcting that framing in a later proceeding is harder. A suspension under EU rules may look final; it is not – but the path back depends on the quality of the filing that was made at the first opportunity.

Do I need a lawyer for internal complaint-handling under the DSA?

You are not required to use a lawyer, but there are practical reasons why legal support changes the outcome. The DSA's requirements for what a valid internal complaint must contain are not straightforward, and neither are the evidentiary standards that make a complaint persuasive rather than merely procedurally complete. In our practice, the sellers who come to us after a rejected first complaint almost always made the same error: they responded to the category of the suspension rather than to the specific reasoning in the statement of reasons. A lawyer who regularly works with DSA complaints on Amazon FR understands what the platform's review process is actually looking for, how to frame a root-cause argument in terms the review system credits, and how to preserve the record for P2B or settlement-body escalation. For sellers with significant revenue on Amazon FR, or where the underlying restriction involves a complex supply-chain, IP, or safety documentation issue, the cost of legal support is typically well below the cost of a prolonged suspension.
