Empty containers were 28.4% of all box moves across the tracked US ports in May 2026. Long Beach had the highest empty share at 36.1%. A high empty share reflects trade imbalance and carrier equipment repositioning, not congestion.
Empty containers were 28.4% of all box moves across the nine tracked US ports in May 2026.

About Empty-container share by US port
This page shows the empty-container share of monthly box volume at each tracked US port: empties as a share of the three container streams the port authorities report, loaded imports, loaded exports and empties, all in TEU. An empty container is a box moving with no cargo in it, repositioned by the carrier to where the next load is, so a high empty share is a read on trade IMBALANCE and equipment flow, not on congestion. A West Coast import gateway that takes in far more loaded boxes than it sends back out has to move the difference back overseas empty, so its empty share runs high; an export-leaning port fills more of its outbound boxes and shows a lower empty share. It is a structural feature of a trade lane, not a delay: nothing here says a box with a high empty share sat longer or moved slower. For how long import boxes actually sit, see the Los Angeles import-container dwell page; for the demand ranking, see the busiest-ports page. The shares are computed from the port authorities' own monthly container statistics, republished by BTS, and each port's three shares sum to 100%.
