The Northwest Seaport Alliance reports that tariffs and elevated retail inventories weighed on full-year total container volume (international and domestic), finishing at 3,156,598 twenty-foot equivalent units (TEUs).

Full-year breakbulk volumes, 327,574 metric tons, decreased 18.7% as high interest rates and tariffs impacted this segment. Full-year auto volumes, 274,001 units, were down 18.9% due to slow auto sales nationwide due to high interest rates and tariffs.
