We would like to inform you of recent regulatory enforcement updates at the ports of Rijeka (Croatia) and Koper (Slovenia) concerning EU ICS2 (Import Control System 2) requirements.

As communicated earlier, we would like to reiterate the guidelines for Full and Partial Filing scenarios under EU ICS2 regulations. To refer to the detailed guidelines: Click Here

Key Change

The port authorities at Rijeka and Koper have now activated their Risk Management Systems (RMS) to validate the completeness of ENS filings performed by respective economic operators, in line with the layered filing framework under ICS2.

The following economic operators must ensure that their respective partial filings are completed at least 24 hours prior to vessel arrival at the compliance load port:

Forwarders (Self-Filing)

Forwarders who have opted for self-filing by nominating the EORI of the next filing party in the shipping instructions must complete the remaining partial filing (F15) directly via the EU ICS2 Single Trader Interface (STI).
Direct Customers (Self-Filing)

Direct customers opting for self-filing by nominating the EORI of the next filing party must complete the required partial filing (F17) via STI.

Operational Impact

If the required partial filings are not completed within the defined timeline :

A HOLD will be imposed by Customs authorities
Shipment will not be allowed to proceed further in the supply chain
Missed vessel connections in case of transshipment
Delays in customs clearance for import shipments

The HOLD will remain in place until complete and compliant data is submitted and validated.

Cost Implications

All costs arising due to such HOLD (including Demurrage, Detention, and other operational costs) will be borne by the "Next Filing Party" (as defined in the shipping instructions) responsible for subsequent partial filing to EU ICS2 system.

For short sea services the cargo will have to be retained on board for missing partial filing to EU ICS2 system and cost associated will be borne by the "Next Filing Party" (as defined in the shipping instructions).

Customer Action Required

To avoid disruptions, we strongly request you to:

Ensure timely submission of HBL or Buyer and Seller data to STI for partial filing cases at least 24 hours prior vessel arrival at compliance load port
Align with your filing party (forwarder/BCO) to ensure compliance before cargo cut-off

Keynote : These measures are part of the EU-wide ICS2 compliance framework, and similar enforcement may be extended to other ports.

Should you have any questions, please feel free to reach out to your customer service representative.

We appreciate your business and look forward to continuing our work together.
