In 2025, with 60.0 million tons of goods handled, the port of Trieste recorded a slight growth of +0.7% compared to the traffic handled in the previous year. The increase was produced by the +4.4% increase in the traffic of the liquid bulk which amounted to almost 43.1 million tonnes, of which 42.0 million tonnes of crude oil disembarked at the SIOT marine terminal (+4.4%). The Authority of Port System of the Eastern Adriatic Sea has announced that The increase is largely due to higher demand for Czech Republic oil supply as a result of the interruption in 2025 of supplies via the Russian pipeline Druzhba, to ensure the country's energy security.

On the other hand, the decline in miscellaneous goods was marked, standing at 16.8 million tons (-7.4%), with only one containerized traffic which, with 681,733 TEUs handled, suffered a decline of -19.0% due to a marked contraction in traffic that began in the second half of the year and linked to the remodulation of services after the cessation of the 2M alliance between the shipping companies MSC and Maersk. The reduction in container traffic was exclusively produced by the contraction of transhipment volumes that have been equal to 144,803TEU (-52.8%), while import-export containers were remained stable at 536,930 TEUs (+0.4%), of which 405,015 containers full (+4.9%). "This trend, even in the presence of a overall negative - observed the President of the Authority of the Port System, Marco Consalvo - confirms the nature of Trieste as a gateway port, oriented to real import-export flows and not to pure transshipment. The decline in TEUs therefore does not signal a loss of competitiveness, but a qualitative selection of traffic, with more goods directly related to the productive economy European Union'.

In the Motorways of the Sea segment, 2025 has closed with 317 thousand ro-ro units transited (+7.4%). In the Dry bulk sector was affected by a downturn -7.3% with 112 thousand tons handled, with the exception of cereals (79 thousand tons, +4.9%).
