Marketplace and Third-Party Seller Producer Obligations: Who Files When You Sell on Amazon, Walmart, or eBay
When a brand sells through Amazon, Walmart Marketplace, eBay, or similar platforms, the question of who is the producer for EPR purposes is not always the platform. Here is how producer-of-record allocation works across UK, EU, and US state regimes for marketplace and third-party-seller models.

Why marketplace sales need their own producer analysis
A brand selling through its own DTC site is straightforward: the brand is the producer in most regimes. A brand selling through a traditional retailer is also generally clear: the brand is typically still the producer, with the retailer as the customer.
Marketplace and third-party seller models complicate the analysis because the platform sits between the brand and the consumer in a way that varies by platform model and by jurisdiction. The platform may be the seller, the fulfillment agent, the importer, or just an intermediary, sometimes within the same brand's portfolio.
The producer determination is not a brand-level question. It can change SKU by SKU and channel by channel.
The relevant variables
For each marketplace channel, the producer determination usually depends on:
- The brand on the package. Does the platform sell its own private label, or are the goods branded by a third-party seller?
- The seller of record. Whose entity name appears on the consumer invoice or sales record?
- The fulfillment model. Does the platform fulfill from its own warehouses (FBA-type model) or does the seller ship directly?
- The importer of record. For cross-border sales, who legally imports the goods into the destination country?
- The platform's express role. Some jurisdictions assign producer status to platforms in specific scenarios; others do not.
How major regimes handle marketplace models
EU PPWR. Distinguishes between:
- Goods sold by the marketplace under its own brand or as the seller-of-record. The marketplace is the producer.
- Goods sold by third-party sellers using the marketplace as a sales channel. The third-party seller is generally the producer. Where the seller is non-EU, an EU-based authorized representative is required, and the marketplace may have ancillary obligations to verify the seller's compliance under platform-liability provisions. Final platform-liability provisions are set in the 2026 PPWR implementing acts.
UK pEPR. Treats online marketplaces as obligated parties in some scenarios, particularly where they handle non-UK sellers' goods or facilitate sales without identifiable UK producers. The specifics depend on UK regulator guidance. Consult current UK pEPR guidance for the 2026 position on online marketplaces.
US state EPR programs.
- California SB 54. Marketplaces and certain online platforms can be deemed producers when no upstream entity qualifies, typically when the third-party seller is non-US and no US importer qualifies. For US-based brands selling through marketplaces, the US brand is generally the producer.
- Oregon, Colorado, Maine, Maryland, Minnesota, Washington. Each has its own treatment of marketplace seller obligations. Generally, the marketplace is not the producer when a qualifying US brand is the seller; the marketplace becomes the producer in fallback scenarios. Consult each state's published rule for 2026 marketplace-of-record provisions.
Common scenarios
Scenario 1, US brand sells through Amazon US (FBA). Amazon fulfills, but the US brand is the seller of record. The US brand is the producer in US state EPR programs. Amazon is not the producer for these third-party sales.
Scenario 2, US brand sells through Amazon EU using FBA-EU. US brand ships inventory to EU FBA centers; consumers in EU member states purchase. The US brand is generally the producer for PPWR and member-state EPR purposes and needs an EU authorized representative. Amazon is not the producer for the third-party sales.
Scenario 3, Non-US brand sells through Amazon US. A non-US brand without a US importer entity may not have a US-based producer. In that case, Amazon may be treated as the producer or may be required to verify the non-US seller's compliance, depending on the state. State-by-state 2026 provisions vary; consult each state's current rule.
Scenario 4, Walmart Marketplace third-party seller. Walmart is the platform; the third-party seller is the seller of record. The third-party seller is generally the producer. Walmart's first-party (private-label) sales are different, Walmart is the producer for those.
Scenario 5, eBay / smaller marketplaces. Generally do not handle fulfillment or take title to goods. The seller is the producer; eBay is not the producer for third-party sales.
Scenario 6, Brand-operated marketplace within a retailer's site. Some retailers operate hybrid models where part of the inventory is owned by the retailer and part by third-party brands selling through the retailer's URL. The producer determination follows the seller-of-record per SKU, not the URL.
What changes for a brand selling through marketplaces
Brands selling through marketplaces typically need to:
- Confirm seller-of-record status per channel and per SKU. The platform's own classification may not match the EPR-relevant determination.
- Maintain producer registration in each obligated jurisdiction even when sales are platform-fulfilled.
- Track shipments by destination market, even when the platform handles fulfillment, to allocate tonnage correctly.
- Verify whether the platform charges back EPR-related fees and reconcile against the producer's own filings to avoid double payment.
A common operational gap: brands assume that because Amazon "handles everything," it also handles EPR. It generally does not, for third-party seller sales.
What this means operationally
Producer determination for marketplace channels is a per-SKU, per-channel exercise, not a brand-level rule. The same brand selling the same SKU through two different platforms or two different fulfillment models can have different producer obligations.
Documenting the producer determination per SKU/channel combination, with the rule applied, makes the filings defensible.
What to do in 2026
- Inventory marketplace channels by platform, fulfillment model, and seller-of-record entity.
- Apply the producer-determination rule per channel for each obligated jurisdiction.
- Confirm registrations in each jurisdiction where the brand is the producer for marketplace sales.
- Reconcile any platform-charged compliance fees against your own filings to avoid double-counting.
How Packgine helps
Packgine carries the producer determination at the SKU/channel level, applies jurisdiction-specific marketplace rules, and produces filings that reflect the actual producer-of-record per channel. When the brand expands into a new platform or a new fulfillment model, the determination logic runs explicitly rather than defaulting to a brand-wide assumption.
