Before every peak season, Amazon Europe faces a new round of compliance reshuffling.

On September 1, EU FBA inbound warehousing will see its strictest policy tightening ever.

From September 1, if you are a non-EU registered cross-border seller storing FBA inventory in the EU and your goods originate outside the EU, you must submit both MRN and EORI information at inbound. Both are mandatory.

The platform checks who imported, who declared, who holds the EORI, and which MRN corresponds to the shipment. This chain must match. The core of the review is authenticity and traceability.

Many sellers think if they only ship to Germany or Spain and do not sell in France, they are safe. The answer is no.

If you are enrolled in Pan-European FBA, Amazon automatically transfers inventory across warehouses to French fulfillment centers. Once goods move to a French warehouse, missing the corresponding MRN and EORI will be judged as non-compliant.

So what are MRN and EORI?

An MRN is an 18-digit unique number generated by EU customs for each import declaration, like a clearance receipt for that shipment. Each shipment has a different MRN. You need to obtain it from the freight forwarder or customs broker handling clearance.

An EORI is a fixed identification number issued by EU customs to a business, like the company's EU customs household registration. The same company's EORI stays fixed and does not change by shipment.

This new rule is mandatory and strictly enforced.

The rule requires that for all eligible shipments, MRN and EORI must be submitted within 60 days after receipt at an Amazon fulfillment center.

If valid information is not submitted in time, the button to create new FBA inbound plans will be disabled, so you cannot replenish the corresponding marketplace. This effectively locks your EU FBA restocking channel.

Existing inventory already in warehouses can still be sold, and in-transit shipments will still be received normally. After you complete the information, restrictions usually lift automatically. But if this happens during Q4 peak season restocking, the restriction can directly cause stockouts and make you miss the peak season.

After the new rule takes effect, the biggest impact is on the traditional double-clearance tax-inclusive model.

Previously, to save costs, sellers used freight forwarders' double-clearance tax-inclusive services, clearing customs under the forwarder's VAT and EORI. Sellers had no corresponding import records, meaning the goods' origin was unclear.

Industry estimates show that after switching to compliant self-tax clearance, profits for some categories may drop by 1–4 percentage points. But the cost of non-compliant inspection is far higher: inspection fees, high storage fees, listing removal, and longer restocking cycles. Total losses are often several times the tariff itself.

Note that the effective date is based on when the shipment arrives at the fulfillment center, not when the shipment was created. For example, if you created and shipped a shipment in late August, as long as the fulfillment center receives it on or after September 1, you must provide MRN and EORI.

With only five days left before the policy takes effect, sellers must start preparing now.

• Check your account: confirm whether Pan-EU is enabled. Non-EU entities using Pan-EU or direct shipments to French warehouses must act.
• Confirm with your freight forwarder: for every EU FBA import shipment, obtain a real and valid MRN clearance receipt and the EORI used for declaration. Refuse tax-inclusive channels without an MRN.
• Upload path in Seller Central: Inventory → Manage Amazon Shipments, and fill in the EORI and MRN in the shipment details.

Gradually tightening compliance is an irreversible trend. Sellers who complete compliance adjustments early will gain an advantage, while those who wait and delay will face increasing operational risks.

With only a few days left before the new rule takes effect, all EU FBA sellers must act immediately to avoid peak-season restocking disruptions caused by compliance issues.
