Rotterdam (UN/LOCODE: NL RTM) is Europe's largest port, handling over 14.2 million TEU annually (2025 data). The port's logistics and customs data exchange operates through Portbase — the Netherlands' Port Community System. Dutch customs (Belastingdienst / Douane) manage export clearance through the DMS system (Douane Management Systeem).

Portbase — How Does It Work?

Portbase is the Port Community System for all Dutch ports, connecting over 4,500 companies and organizations. Portbase provides the digital backbone for container tracking, customs integration, and logistics coordination in Rotterdam.

Key components for export:

Export Reporting — electronic export notification system linking customs declarations to port operations
DMS (Douane Management Systeem) — the Dutch customs system handling export declarations and MRN processing
Container tracking — real-time container status and loading confirmation through Portbase
