Customs Regulations and Maritime Routes in France

The EU customs framework at French ports

France, as an EU member state, applies the Union Customs Code (UCC) — the primary legal framework governing the import, export, and transit of goods through EU territory. The UCC, which entered into force progressively from 2016, replaced the earlier Community Customs Code and introduced significant changes to declaration processes, guarantee systems, and special customs procedures.

Customs control at French ports is exercised by the Direction générale des douanes et droits indirects (DGDDI), operating under the Ministry responsible for public accounts. DGDDI officers are present at all commercial port entry points, coordinating with other inspection bodies — notably the DDPP (Direction départementale de la protection des populations) for sanitary controls on food products, and the ANSES laboratories for veterinary and phytosanitary checks.

Import procedures at French ports

When a vessel arrives at a French commercial port, the cargo it carries must be declared to customs through a set of procedural steps governed by the UCC and its implementing regulations:

1. Entry Summary Declaration (ENS): Before the vessel's arrival, the carrier must file an Entry Summary Declaration through the French SAFE system, which feeds into the EU-wide ICS2 (Import Control System 2) framework. This declaration covers cargo descriptions, shipper and consignee details, and container/seal numbers.
2. Temporary Storage: Upon discharge from the vessel, goods enter a period of temporary storage at the terminal. This period is limited under the UCC (generally up to 90 days for sea freight) and the goods must be placed under a customs procedure before the deadline expires.
3. Customs Declaration: The importer or their customs broker files a customs declaration (Single Administrative Document, or SAD) specifying the customs procedure requested — free circulation, inward processing, customs warehousing, etc. The declaration includes the commodity classification under the Combined Nomenclature (CN), the customs value, the origin of the goods, and applicable duties and taxes.
4. Release for Free Circulation: Once the declaration is accepted and any applicable duties paid, the goods are released. Physical inspection may be conducted on a risk-selected basis before release.

Authorised Economic Operator (AEO)

Companies that move goods regularly through EU customs and meet defined standards of compliance, financial solvency, and security can apply for AEO status. AEO-certified importers benefit from fewer physical controls, priority lanes at customs, and simplified procedure entitlements. DGDDI administers AEO certifications in France; the official guidance is published on douane.gouv.fr.

Export procedures

For goods leaving France by sea, an Export Declaration must be filed through DELTA X before the goods are brought into the port zone. The customs system assigns an Export Accompanying Document (EAD) with a Movement Reference Number (MRN) that accompanies the goods from the declarant's premises to the port. At the port exit, the system records the exit of the goods, triggering the zero-rate VAT treatment applicable to exports.

Dual-use goods — items with both civilian and military applications — require an export authorisation from the Secrétariat général de la défense et de la sécurité nationale (SGDSN) before an export declaration can be accepted. Similarly, certain agricultural commodities exported under EU common agricultural policy mechanisms require export licences or refund applications processed through FranceAgriMer.

Sanitary and phytosanitary controls

Goods of animal or plant origin entering France from outside the EU must pass through a Border Inspection Post (BIP / Poste d'inspection frontalier) for mandatory sanitary and phytosanitary checks. French ports with designated BIPs include Le Havre, Marseille, Dunkerque, and others. The BIP system operates under EU Regulation 2017/625 on official controls along the agri-food chain.

Physical inspections at BIPs involve documentary checks, identity checks, and physical examination of the consignment, which may include sampling and laboratory analysis. Products found non-compliant are subject to refusal, destruction, or re-dispatch at the importer's expense.

Main maritime shipping routes

French ports are situated at the intersection of several major global shipping routes. The geographic position of the French coastline — spanning the Atlantic, English Channel, North Sea, and Mediterranean — means different French ports serve different trade corridors.

North Range routes (English Channel / North Sea)

Le Havre and Dunkerque participate in the Northern Range, the cluster of major European ports stretching from Le Havre through Zeebrugge, Antwerp, Rotterdam, and Hamburg. The largest container vessel services — deployed by alliances such as THE Alliance, Ocean Alliance, and 2M — call at two or three Northern Range ports per rotation, with Le Havre typically the westernmost French call on eastbound Asia-Europe services.

Feeder services connect Le Havre and Dunkerque to smaller ports in the United Kingdom, Ireland, Scandinavia, and the Baltic, redistributing cargo discharged from mother vessels.

Atlantic routes

Nantes-Saint-Nazaire and La Rochelle are positioned on Atlantic trade routes connecting France to West Africa, Brazil, and North America. La Rochelle handles substantial volumes of agricultural commodities exported to North Africa and the Middle East. Saint-Nazaire is associated with shipbuilding (the STX/Chantiers de l'Atlantique shipyard) as well as commercial port activity including wind turbine component imports for offshore energy projects.

Mediterranean routes

Marseille-Fos serves Asia-Europe container services transiting through the Suez Canal, as well as intra-Mediterranean feeder networks connecting to ports in Spain, Italy, Greece, Turkey, and North Africa. The port competes with Genoa, Barcelona, and Valencia for Mediterranean gateway traffic destined for the French and Swiss inland markets.

Since the Suez Canal's role in global shipping became particularly visible during the 2021 blockage incident and subsequent capacity pressures, discussions around alternative routing — including the Cape of Good Hope diversion — have affected scheduling patterns on Asia-Europe services serving Marseille.

Cross-Channel routes

The shortest maritime crossing between France and the United Kingdom operates between Calais and Dover, with Dunkerque-Dover and Calais-Folkestone as additional options. These short-sea routes carry an exceptionally high volume of freight trailers and passenger vehicles. Since the UKs departure from the EU Single Market, additional customs formalities apply to both directions of cross-Channel freight, and port operators at Calais and Dunkerque have invested significantly in border control infrastructure to accommodate the increased documentation requirements.
