About Seattle/Tacoma container volume (TEU)
This page tracks monthly container volume at the Port of Seattle/Tacoma in TEU, twenty-foot equivalent units, split into loaded imports, loaded exports and empty containers. Loaded imports are the demand signal a US importer watches; empties are a tell about trade imbalance and equipment. The numbers are the port authority's own, re-published by BTS, and they land weeks after the month they cover, so a reading here is the latest month available rather than the current week.
