Amazon’s recent changes to customs documentation requirements across the Pan-European fulfillment network impose new hurdles for non-EU sellers, emphasizing the need for accurate MRN and EORI data to ensure seamless inventory replenishment and compliance.
Amazon’s Pan-European Customs Changes Put New Pressure on Non-EU Sellers
Amazon’s latest customs compliance changes are creating fresh pressure for non-EU sellers that use the company’s Pan-European fulfillment network. Beginning September 1, new import documentation requirements will affect how inventory enters and moves through the EU, requiring merchants to provide more detailed customs information for shipments connected to Amazon’s EU fulfillment centers.
According to notices described in industry reports and updates in Seller Central, sellers shipping inventory to Amazon warehouses in the EU will need to provide two key identifiers for every applicable shipment: a Movement Reference Number (MRN) and an Economic Operators Registration and Identification (EORI) number.
The new requirement expands a rule that had already applied in France to the wider Pan-European fulfillment program. It now includes other markets such as Germany, Italy, Spain and Poland, among others. For sellers operating cross-border electronics, mobile accessories, lifestyle products or other goods through Amazon’s European logistics network, the change could affect more than customs paperwork. It may also influence inventory planning, sourcing relationships, freight contracts and the speed at which products can be replenished.
What the MRN and EORI Requirements Mean
The MRN is the customs declaration reference associated with a shipment. It provides a reference point for the relevant import declaration and helps identify the customs process connected to goods entering the EU.
The EORI, meanwhile, identifies a company within EU customs systems. It is used to link a business to customs-related activity and documentation. Together, the MRN and EORI give Amazon more visibility into the import records connected to inventory stored in its European fulfillment network.
For sellers, the central issue is not simply obtaining two pieces of information. The larger challenge is ensuring that the information is available, accurate and connected to the correct shipment and business entity. A merchant may have products moving through several stages of sourcing and logistics before they arrive at an Amazon warehouse. If customs data is held by a freight forwarder or another service provider, the seller may not automatically receive the records Amazon now expects.
This is particularly important for businesses that have relied on duty-inclusive logistics structures. Under those arrangements, freight forwarders may have handled customs clearance under their own VAT or customs arrangements. In such cases, the seller may have received a delivered shipment without receiving the complete underlying import documentation.
That model can be convenient from an operational perspective. It may simplify the seller’s immediate logistics workload by placing customs coordination with the provider. However, Amazon’s updated requirements mean that merchants may now need access to documentation that previously remained with the logistics partner.
Why the Change Matters to Pan-European Sellers
Amazon’s Pan-European fulfillment model allows inventory to be distributed through fulfillment centers in multiple European markets. For sellers, the network can support cross-border sales while reducing the need to manage each customer delivery separately.
However, the model also depends on consistent compliance across the supply chain. Inventory must be imported, documented, and recorded in a way that supports its movement into Amazon’s EU warehouses. When documentation standards change, sellers must make sure that their sourcing and logistics arrangements can produce the necessary records.
The expansion beyond France means that sellers cannot treat the requirement as a country-specific issue. Merchants using fulfillment centers in Germany, Italy, Spain, Poland and other participating markets may need to review their broader EU process rather than addressing only one destination.
The impact may be especially significant for non-EU sellers. A company based outside the bloc may rely on a freight forwarder to coordinate international transportation, customs clearance and delivery to Amazon. If the forwarder has historically managed the import process on the seller’s behalf, the merchant may need to revise the relationship so that MRN and EORI information is returned after clearance.
This could affect businesses of different sizes. A large supplier may have several logistics providers, multiple sourcing locations, and inventory moving through different routes. A smaller seller may depend on a single forwarder and have less visibility into the customs process. In both cases, the commercial requirement is similar: sellers need to be able to connect their inbound shipments with the customs information Amazon requires.
The 60-Day Grace Period
Amazon is giving sellers a 60-day grace period to comply with the new requirements. During that period, merchants have time to collect and upload the required MRN and EORI details.
If the information is not uploaded within the grace period, sellers may lose the ability to create new inbound shipments to Amazon’s EU fulfillment centers. This does not mean that all existing inventory will immediately be removed or blocked. Goods already in transit and inventory already received are not affected under the described policy.
The more immediate risk concerns future replenishment. A seller may continue to have products available in Amazon’s fulfillment network, but could face difficulty sending additional inventory if the required records are incomplete. For businesses with fast-moving products, including consumer electronics, mobile devices, accessories or lifestyle goods, a disruption in replenishment could place pressure on inventory availability.
The timetable also creates a practical deadline for logistics reviews. Sellers may need to renegotiate contracts, establish new document-sharing procedures, and confirm that customs data is returned after clearance. Waiting until a new shipment is ready to depart could leave too little time to resolve gaps in documentation.
Logistics Providers Become a Central Part of Compliance
The rule change places freight forwarders and other logistics providers at the center of the compliance process. A seller may not be able to satisfy Amazon’s requirements without cooperation from the company that handled customs clearance.
The first step for many merchants will be to determine whether their providers can supply post-clearance MRN and EORI information for each relevant shipment. Sellers may also need to clarify which entity appears in the customs records and whether the documentation corresponds to the seller’s own business information or the provider’s arrangements.
This distinction matters because duty-inclusive shipping structures can involve customs and VAT processes managed by the forwarder. If a provider cleared goods under its own arrangements, the seller may need to understand how that affects the records Amazon expects to see.
The practical response is likely to be administrative rather than operational at first. Merchants may need to:
- - Request MRN and EORI details from freight forwarders after customs clearance.
- - Confirm that each record is linked to the correct shipment.
- - Add documentation obligations to logistics service agreements.
- - Review previous shipments for missing import information.
- - Establish a process for storing customs records.
- - Verify that future inbound shipments can be supported by complete documentation.
These steps do not necessarily require sellers to change their product sourcing or physical transportation routes immediately. However, they may change how sellers manage data across the supply chain. A merchant that previously viewed customs documentation as the logistics provider’s responsibility may now need to treat it as an internal compliance requirement as well.
Implications for Sourcing and Inventory Planning
The requirement may also influence sourcing decisions. Sellers that source products from outside the EU often coordinate manufacturing, freight, customs clearance and marketplace fulfillment through several parties. When each participant holds only part of the shipment information, it can become difficult to assemble a complete record.
For example, a business may purchase goods from an overseas manufacturer, use a third-party freight forwarder, and send the inventory to an Amazon fulfillment center in the EU. If the forwarder manages customs but does not automatically provide the MRN and EORI information, the seller may not have the records needed for Amazon’s system.
This makes documentation flow an important part of supplier and logistics selection. Price, delivery time and transportation terms remain relevant, but sellers may also need to evaluate whether a provider can reliably return customs data.
The change could be particularly relevant for sellers with frequent replenishment cycles. A merchant may be able to manage a small number of shipments manually, but repeated inbound movements can create a larger administrative burden if records are delivered inconsistently. Establishing a standard process with the logistics provider may reduce the risk of missing information before the grace period ends.
A Broader Compliance Trend
For B2B suppliers, freight forwarders and marketplace sellers, Amazon’s update points to a wider trend in European trade compliance. Customs documentation is becoming an increasingly important part of maintaining access to major fulfillment and sales channels.
The ability to move goods through the supply chain is no longer the only concern. Sellers must also be able to demonstrate how those goods entered the market and which business information is associated with the import process. Clean records may therefore become a practical condition of continued growth.
This does not mean that inventory already in transit or already received will be affected by the described requirement. It does mean that future replenishment could depend on whether sellers can provide the necessary documentation.
For non-EU merchants, the immediate priority is to understand how their existing logistics arrangements work in practice. A contract may describe transportation and delivery responsibilities without clearly explaining how customs records are transferred back to the seller. The new requirement makes that information-sharing process more important.
What Sellers Should Review Now
Sellers using Amazon’s Pan-European fulfillment network should review their current inbound process before the 60-day grace period expires. The review should focus on whether every relevant shipment can be matched with the required MRN and EORI details.
They should also examine past shipments, particularly those handled under duty-inclusive logistics structures. Missing historical records may not affect inventory already received, but identifying documentation gaps can help reveal whether the same problem may affect future shipments.
The key issue is accountability. If a freight forwarder handles customs clearance, the seller should know how and when the relevant information will be delivered. If the seller’s records do not match Amazon’s requirements, future inbound shipments may be delayed or unavailable for creation.
Amazon’s change therefore connects customs compliance with marketplace operations. Sellers may continue to source products, arrange transportation, and sell through the EU, but their ability to replenish Amazon inventory may depend on the quality of their import documentation.
