Ports of Seattle and Tacoma container volume dropped 6% in July
The Northwest Seaport Alliance's full international imports in July increased 3.5% from June while year-over year volumes decreased 11.4%. Both volume variances were driven by ongoing market volatility resulting from tariffs and a strong July 2024 when the NWSA successfully handled a surge of cargo diversions from Canada during their labor disruptions.
Fluid vessel and rail operations have contributed to a significant increase in export volume compared to the same time last year, driving exports up by 19.9%.
Total container volume (international and domestic) for the month reached 249,578 twenty-foot equivalent units (TEUs), down 6% compared to July 2024. YTD volumes are up 3.5%, with full imports growing 0.9% and full exports declining 1%.
Domestic container volumes increased 2.6% compared to YTD 2024. Alaska volumes increased 1.5%, and Hawaii volumes increased 8.7%.
Total breakbulk volume decreased 23.2% for 206,180 metric tons YTD. High interest rates and tariffs continue to impact this segment. Auto volumes were 170,076 units, down 15.9% YTD due to the slowing of auto sales nationwide.
