Do third-party sellers need EPR compliance for marketplaces?

Yes, third-party sellers must secure their own Extended Producer Responsibility (EPR) registration numbers to sell on e-commerce marketplaces, as platforms are now legally required to block non-compliant merchants or assume financial liability for their packaging and product waste. In France, marketplaces have been required to declare products for sellers who lack a Unique Identifier since early 2022.

For years, independent merchants could ship goods globally through major digital marketplaces with very little regulatory friction. A seller based in Asia or North America could easily list a packaged electronic device on a European platform and reach millions of buyers without worrying about local waste management laws. This created an uneven playing field where domestic brands paid their environmental fees to fund recycling infrastructure, while overseas cross-border sellers effectively bypassed the system, leaving local municipalities to handle their waste for free.

To fix this gap, environmental authorities across Europe have shifted their enforcement strategy directly onto the digital platforms. Marketplaces are now positioned as regulatory gatekeepers. If an independent seller wishes to list a product, they must prove they are participating in the relevant national recycling schemes. For an e-commerce entrepreneur, this means that ignoring environmental compliance no longer just risks a hypothetical fine from a foreign government; it risks an immediate suspension of their storefront and frozen sales.

What third-party seller compliance actually means

Third-party seller compliance means the seller listing on a marketplace, not the marketplace itself, is the producer who must register and pay. Under modern Extended Producer Responsibility frameworks, the duty to finance the collection and recycling of waste lies with the producer placing the item onto a national market. In the context of e-commerce, the third-party seller is generally considered this producer. To operate legally, the seller must register with a national registry or a Producer Responsibility Organisation, pay eco-modulated fees based on the materials they ship, and receive a formal registration number.

Marketplaces are obligated to collect and verify these registration numbers from their third-party sellers before allowing them to trade. The European Union's Packaging and Packaging Waste Regulation (PPWR) explicitly mandates this gatekeeper role to prevent free-riding, tying it directly to the traceability rules laid out in the Digital Services Act (Regulation EU 2022/2065) (Packaging and Packaging Waste Regulation (EU) 2025/40). Platforms must secure this compliance information before allowing any seller to use their digital infrastructure to reach local consumers.

In that context, where providers of online platforms... Enable consumers to conclude distance contracts with producers, they should... Obtain information from those producers about their compliance with the extended producer responsibility obligations set out in this Regulation.

If a seller fails to provide this proof, the platform must take action. Depending on the specific national law, the platform will either suppress the seller's product listings entirely or act as the deemed producer. In the deemed producer scenario, the platform pays the environmental fees on the seller's behalf and subsequently charges those costs back to the merchant, often applying steep administrative markups for the inconvenience.

Does this apply to me?

If you use a digital portal, platform, or app to sell physical goods directly to end users in countries with active EPR laws, these compliance requirements apply to your business. The scope of your liability depends on what you are selling and where your buyers are located. Almost all consumer goods require packaging compliance, while specific products like electronics, batteries, and textiles trigger additional, separate EPR obligations that require their own distinct registration numbers.

In France, since early 2022, EPR obligations apply directly to marketplaces (My membership - Citeo.com). If you sell into France via a platform and do not provide your Unique Identifier, the marketplace is legally required to declare the products on your behalf. To manage this, the platform must keep an up-to-date register of its third-party sellers, tracking the number of packaged products sold, the seller's identity, and their unique identifier for each EPR scheme.

In the United Kingdom, the rules apply differently depending on where the seller is based. Operating an online marketplace is a regulated packaging activity in the UK if the website or app allows non-UK businesses to sell their goods into the UK (Packaging waste: prepare for extended producer responsibility - Daera). In this scenario, the marketplace assumes the compliance burden for the foreign seller. However, if the platform only hosts UK-based organisations, it is not classed as carrying out the marketplace activity. This leaves the primary compliance and reporting burden squarely on the individual UK-based third-party seller, who must register and report their own data if they meet the national thresholds.

What data must a marketplace collect to prove seller compliance?

The rules for marketplace compliance rest on specific data points and legal mechanisms established by the overarching regulations, which merchants must track exactly.

Common misconceptions about third-party seller compliance

“The marketplace automatically handles all my environmental fees for me”

While some platforms offer a pay-on-behalf service, this is not the default standard across all countries or all waste streams. Even when a marketplace does pay your fees, they generally charge you a premium for doing so and still require you to eventually obtain your own registration number. Under the PPWR, you are expected to provide your own registration number or self-certification to the platform to prove you are handling your own obligations.

“I only need one EPR registration number to sell across European marketplaces”

This is a frequent misunderstanding of how European environmental law works. EPR is managed at a national level. If you sell through a marketplace into Germany, France, and Spain, you need to register with the relevant authorities in all three countries independently. Providing a German LUCID number to your marketplace dashboard will not unblock your suspended listings in France.

“Small sellers are exempt from providing compliance proof to platforms”

There is no universal small business exemption for marketplace compliance. In many European countries, the threshold for packaging EPR registration is zero, meaning that selling even one packaged item requires a registration number. The marketplace cannot allow you to sell that single item without verifying your compliance status first, regardless of how small your annual revenue is.

“My drop-shipping supplier handles the compliance, so I do not have to”

If you operate a drop-shipping model where a factory ships goods directly to the consumer, but the consumer bought the item from your branded marketplace storefront, you are generally the seller of record. The marketplace will look to you, the merchant holding the seller account, to provide the EPR registration numbers, not your anonymous overseas supplier.

5 examples of third-party seller compliance scenarios

1. Non-EU electronics sellers

A consumer electronics merchant based in China lists products on a European marketplace. Because the seller is based outside the EU, the marketplace demands proof of registration for both Waste Electrical and Electronic Equipment (WEEE) and packaging. Without these numbers, the platform hides the listings from European buyers.

2. The French pay-on-behalf mechanism

A small independent clothing brand selling into France ignores the marketplace's request for a textile and packaging Unique Identifier. To comply with French law, the marketplace keeps the listings active but calculates the estimated eco-fees, pays them to the French authorities, and deducts the cost directly from the brand's sales disbursements.

3. UK marketplace import liability

A digital platform operating in the UK hosts sellers from the United States. Because the platform allows non-UK businesses to sell into the country, it triggers the specific UK online marketplace activity rules, forcing the platform itself to track and report the packaging data for those imported American goods.

4. Domestic UK marketplace sales

An app designed exclusively to help UK-based independent bookstores sell their goods to UK readers. Because all sellers are domestic UK organisations, the app operator is not classed as carrying out the marketplace activity, leaving each bookstore to determine their own EPR obligations.

5. Self-certification under PPWR

A merchant providing a formal self-certification document to their marketplace platform, legally confirming that they only offer packaging that fully complies with the extended producer responsibility requirements in the specific Member State where the consumer is located.

Terms related to third-party seller compliance

Frequently asked questions

Why is my marketplace suddenly asking for an EPR number?

Marketplaces are asking for Extended Producer Responsibility registration numbers because new national and European regulations mandate that they do so. Laws now dictate that platforms must obtain this information to prevent free-riding, and they face severe penalties if they allow non-compliant sellers to trade on their websites.

What information must platforms collect under the new European rules?

Under the Packaging and Packaging Waste Regulation, providers of online platforms must obtain specific information from producers before allowing them to use their services. This generally includes an EPR registration number, or a self-certification by the producer confirming that they comply with the rules in the Member State where the consumer is located.

Does the UK hold marketplaces responsible for their sellers?

It depends on where the seller is located. In the UK, owning an online marketplace is a defined packaging activity if the platform allows non-UK businesses to sell their goods into the UK. However, if the platform only sells goods from UK-based organisations, it is not classed as carrying out this activity.

What happens if I do not provide my registration number?

If you fail to provide your EPR registration number, the marketplace is legally required to take action. In most countries, this means the platform will suspend your seller account or block your listings from being visible to consumers in that specific country. In some jurisdictions like France, the platform may pay the fees on your behalf and charge you a premium.

Can a marketplace simply agree to pay the fees for me?

Yes, in some circumstances. The regulations state that the financial contributions imposed on producers are without prejudice to voluntary agreements where online marketplaces, acting on a written mandate, consent to accept all or part of those costs on behalf of the producers. However, the merchant is still ultimately responsible for ensuring the compliance is handled.

Do I need a different number for each European country I sell in?

Yes. Extended Producer Responsibility is enforced at a national level, not centrally by the European Union. You must register with the specific national authority or Producer Responsibility Organisation in every individual country where you sell goods to end consumers, and you must supply all of those different numbers to your marketplace.
