Port Throughput

Rotterdam handles 26% of the ranked tonnage and, with Antwerp-Bruges, 42% of it — volumes then fall by roughly two-thirds from the second port to the third.

Gross weight of goods handled (all traffic), summed across the year’s quarters; the inbound share is the discharged portion of that tonnage, and the trend line is each port’s annual total over the available history. The ranked tonnage is a top-25 of Europe’s busiest harbours, not a continental total. Officially-reported tonnage is the demand-side counterpart to AIS-derived port activity. Commodity flows →
