Ocean Network Express (ONE) container tracking — what the delay is costing you

Tracking tells you where the box is. It never tells you what it is about to cost. Enter a Ocean Network Express (ONE) container number and your discharge port to get the last free day and the dollar exposure of every day past it — carrier demurrage, detention and, where it runs separately, terminal storage.

Ocean Network Express (ONE) bills demurrage and detention as separate clocks at Los Angeles / Long Beach. Discharge.

Market-typical per-diem for this region, escalated through the published band structure. Your service contract or the carrier filing overrides it — we verify against the actual tariff on a free audit.

The Ocean Network Express (ONE) gotcha

On several intra-Asia trades ONE grants one combined free period; counting two separately overstates your free time.

Already been billed by Ocean Network Express (ONE)?

A charge that does not serve an incentive purpose, or an invoice missing required elements, is disputable. Send three recent invoices and one bill of lading and we return a written leak report in 48 hours — free, no contract.
