Seattle-Tacoma Container Volumes Fall 12.4% in New Shipping Update
Container Volumes Decline
The Northwest Seaport Alliance reported year-to-date container throughput of 1,433,525 TEU at the ports of Seattle and Tacoma, down 12.4%, according to a July 24 report from WorldCargo News. The two ports form a major US gateway for transpacific international shipping.
The decline indicates that less containerized cargo moved through the gateway than in the same period a year earlier. The published figures measure total port throughput; they do not by themselves identify a single cause or show the performance of every individual trade lane.
Imports Lead the Drop
Full import containers were down 13.9% year to date, a steeper decline than the 1.2% decrease in full exports. Despite the export decline, full export volume remained 1.8% above the gateway’s five-year average.
The difference between imports and exports is important for capacity planning. Lower inbound volumes can change vessel space, equipment positioning and inland transport demand, but the figures do not guarantee lower freight rates or faster terminal handling.
What China-US Shippers Should Watch
China-origin importers using Seattle or Tacoma should monitor carrier schedules, blank sailings, container availability and rail connections before committing cargo. Port-wide volume weakness can lead carriers and terminals to adjust operations even when an individual shipment remains on schedule.
Shippers should compare Pacific Northwest routings with other US gateways using total landed cost, delivery location and inland transit requirements. Booking decisions should rely on current sailing and terminal data, not the headline volume decline alone.
