ENS — Entry Summary Declaration — is the European Union's advance cargo security declaration. It is the EU counterpart to U.S. ISF and AMS, required for goods entering the customs territory of the EU regardless of whether the goods will actually be released into free circulation.
Filing timing depends on mode:
- Deep-sea container traffic — 24 hours before lading at the foreign port (mirrors the U.S. 24-Hour Rule)
- Deep-sea bulk and break-bulk — 4 hours before arrival
- Short-sea (intra-EU and near-EU) — 2 hours before arrival
- Air long-haul — 4 hours before arrival
- Air short-haul (under 4 hours flight time) — by time of actual takeoff
- Rail and inland waterways — 2 hours before arrival
- Road — 1 hour before arrival
Responsibility lies with the carrier (or, by arrangement, a representative such as a freight forwarder or NVOCC).
ENS has been substantially modernized through ICS2 — the EU Import Control System 2 — which rolled out in three releases between 2021 and 2024. ICS2 introduced harmonized pre-loading and pre-arrival data sets across all modes, and requires submission of HS codes at 6-digit minimum (a notable change from the legacy ICS regime).
ENS data is used by EU customs authorities to perform Common Risk Analysis (CRA) and to issue "Do Not Load" instructions when warranted.
