CEMS / e-Carina — customs modernised post-2013

Croatia's EU accession on 1 July 2013 triggered an immediate dismantling of internal customs borders with Slovenia and Hungary, and a sweeping national system overhaul. Carinska uprava (customs administration) operates from the CEMS (Carinski elektronički modul) and the e-Carina platform, integrated with the UCC (Union Customs Code, Regulation EU 952/2013). Internal Schengen land borders fell on 1 January 2023, making BA / RS / ME crossings the new EU external boundary.

History — EU accession, Schengen, UCC

Before 2013, Croatia ran a post-Yugoslav customs regime with national procedures. EU accession on 1 July 2013 imposed within weeks: disappearance of intra-EU customs checks (SI and HU), switch to the Common Customs Tariff, adoption of the Harmonised System (HS) and Combined Nomenclature (CN).

UCC application in May 2016 (Regulation EU 952/2013, succeeding the 1992 CCC) forced a systems overhaul: Croatia progressively rolled out NCTS phase 4 then phase 5, AES, ICS2, and the EORI system. The 2023 euro switch and Schengen entry the same year shifted external borders toward BiH, Serbia, and Montenegro — now the main HR customs operational hot zones.

Before 2013 | Carinska uprava (customs administration) runs checkpoints on
            | land borders with SI, HU, RS, BA, ME. National customs
            | codes and non-EU procedures.
            |
2013-07-01  | EU accession — internal customs borders with SI and HU
            | disappear. Integration with the Common Customs Tariff and
            | the CCC (Directive 992/2008/EC) framework.
            |
2016-05-01  | UCC (Union Customs Code, Regulation EU 952/2013) applies —
            | Croatia subject like every Member State. CEMS overhauled.
            |
2017-2019   | Progressive rollout of EU systems — NCTS (computerised
            | transit), AES (Automated Export System), EORI (Economic
            | Operators Registration), CDS (Customs Decisions).
            |
2021        | Launch of the e-Carina portal (carina.gov.hr) consolidating
            | online services for economic operators.
            |
2023-01-01  | Eurozone entry — all duties and taxes in EUR. Schengen entry
            | for land borders (HU and SI), checks removed. BA/RS/ME
            | borders become the new EU external boundary.
            |
2023-2024   | ICS2 phase 3 — rollout of maritime and land entry summary
            | declarations. Port of Rijeka on the front line.
            |
2025-2026   | UCC re-engineering — preparing the 2nd-generation EU systems
            | (UCC reform 2027-2028) with ePAS, EU Single Window, and
            | VAT-CCT integration.

Governance — Carinska uprava + DG TAXUD

Carinska uprava Republike Hrvatske, integrated with Porezna uprava under a single "Carinska uprava" directorate of the Ministarstvo financija, handles operations: declarations, physical controls, EORI, AEO (Authorised Economic Operator).

EU coordination flows through the European Commission's DG TAXUD. The relevant EU systems — NCTS, AES, ICS2 — are operated by DG TAXUD IT services, with national Croatian nodes hosted by APIS IT. The Customs Trader Portal (CTP) on the HR side is e-Carina.

Technical schema — CEMS + NCTS + ICS2

Main flows follow the WCO (World Customs Organization) data models imposed by DG TAXUD:

• NCTS phase 5 — computerised transit, messages CC015B (declaration), CC013B (amendment), CC029B (release).
• AES (Automated Export System) — export declaration, message CC515B + CC528B (exit confirmation).
• ICS2 (Import Control System 2) — safety & security entry summary declaration, deployed in 3 phases (air Express, postal, maritime/land).
• EORI — Economic Operators Registration and Identification, format HR + OIB for HR.
• EU CTP (Customs Trader Portal) — unified EU portal for customs decisions (CDS), accessible via HR e-Carina.

Croatia vs neighbours (SI, HU) — Adriatic corridor

Adoption — Rijeka port, BiH/RS border

• Port of Rijeka — ~14M tonnes freight/year, ~280K TEU containers, reference ICS2 maritime entry point.
• BA border — ~932 km, main crossings Stara Gradiška, Slavonski Šamac, Metković. Heavy-truck flows from BiH (including EU imports from Sarajevo, Mostar).
• RS border — ~314 km, crossings Bajakovo (A3 Belgrade-Zagreb motorway), Tovarnik. Major Türkiye -> EU Balkan transit traffic.
• ME border — ~22 km, single crossing Karasovići. Modest but sensitive volume (Adriatic tourism).
• EORI HR — ~60,000 registered economic operators in 2026, including ~5,000 AEO-certified (Authorised Economic Operator status).

Common pitfalls

• Malformed HR EORI. Correct format: HR + 11 OIB digits. Many foreign service providers add a different HR prefix format — ICS2 / NCTS rejection.
• Confusing Schengen and customs union. The HR-SI land border has been open since 2023 (Schengen + customs union). But HR-BA stays controlled — EU external border. Frequent error among new HR exporters.
• Thinking France/IT/DE accepts HR LIB. Croatian internal-transit waivers (LIB-HR) are not recognised abroad. Use NCTS T1 or T2 depending on status.
• Stale HS codes. Combined Nomenclature (CN) is updated annually (CN 2026 currently). A CN 2022 code is rejected. Always follow EUR-Lex publications.
• ICS2 phase 3 unprepared. Maritime operators landing at Rijeka must submit an ENS (Entry Summary Declaration) at least 24 h before arrival. Non-compliance = port block + fine.
