What exactly is changing in the EU customs rules?
Until 2026, shipments below a certain value could cross the border without a full customs procedure. That exemption is being removed. From July 2026, every shipment, including low-value ones, is subject to full declaration and documentation requirements. The most widely discussed measure is the new fee of 3 euros per parcel. But as Paweł Zakielarz, CEO of Shopreturns, puts it: those 3 euros are probably the least significant challenge. The real risk lies in compliance failures. Businesses that lack end-to-end traceability and documentation per shipment risk every return becoming a new customs moment, with associated costs that can easily exceed the value of the shipment itself.
Why is the return flow the biggest problem?
Until now, a return shipment was operationally treated as a domestic movement once the parcel had cleared customs. That is changing. From July 2026, a return to a non-EU supplier can be treated as a new import event when the parcel comes back. Businesses without unambiguous documentation, a clear link between the original customs document and the return, previously risked an administrative warning. Going forward, they risk double charges. In environments where return rates are high in certain product categories, this adds up quickly. The core of the problem is not customs legislation itself, but the quality of the underlying data: is the shipment reference unambiguous, is the HS-code consistent, is the value declaration correct and traceable to the return?
What do the new EU customs rules mean for logistics service providers?
Logistics parties that clear goods on behalf of clients become jointly responsible for the completeness of the declaration. That is not new, but the scale is. Where previously a portion of goods flows could be kept outside the full declaration process, every parcel must now go through the same pipeline. For customs brokers and freight forwarders, this means more volume, more declaration moments, and a greater risk of errors if you are still working manually or with disconnected systems. The question is not whether your system can handle this, but whether your data can. Structurally missing fields such as shipment reference, value declaration, or country of origin are no longer acceptable as an operational inconvenience. They become a financial risk.
Structured data is no longer a luxury, but a prerequisite
The core response to this regulation is not buying more software. It is ensuring your operational data is correct before a document crosses the border. That means: one source record per shipment, automatic validation of mandatory fields, and a link between inbound and outbound movements so that a return can always be traced back to the original declaration. AI tools can help with reading documents, matching shipment references, and flagging missing fields, but only when there is a structure to build on. Businesses still working with loose emails, separate spreadsheets per client, or manually retyped value declarations have a structural problem, not a technology problem.
What can you do right now?
Start with an audit of your current shipment documentation. Which fields are mandatory under the new rules, and how many of your current inbound shipments already supply those fields consistently? That gives you a factual picture of your exposure. From there, you can prioritize: which documentation flows carry the most risk, which clients or suppliers provide the sloppiest data, and where are the highest return rates? Those are the areas where it pays to invest first in structured ingestion and validation, before the import moment, not after. Businesses that wait for the first double charge to arrive have already lost the argument.
