Demurrage Charges by Shipping Line
US Demurrage and Detention Charges
United States carriers on this page publish free-day allowances that vary by container type and direction (see 20TK import, 40TK import, 20TK export below) before per-day demurrage and detention slab rates apply. This page tracks 3,448 source-backed rows across 6 carriers, each tied to a published carrier tariff.
What This Page Covers
This United States page is generated from promoted ShippingRates demurrage and detention charges rows that include source URL or source file provenance. It is meant for operators, developers, and logistics agents comparing carrier-backed cost signals before a quote becomes commercial.
Rows that do not have source provenance, cannot be represented safely, or fall below the configured coverage threshold are not used for this public page. That keeps this content cluster aligned with the ShippingRates methodology.
How United States Demurrage & Detention Charges Work
Demurrage applies when a container sits inside the terminal beyond its allotted free days; detention applies once the container leaves the terminal but is returned late. For United States, both are billed as escalating daily slabs — the per-day rate rises the longer the container is held, which is why a short delay and a long delay are not simply multiples of each other.
Free-day allowances and slab rates differ by carrier, by direction, and by container type, and they change as carriers refile tariffs. The 6 carriers on this page are therefore shown as individual source-backed tariff rows. Comparing them side by side is the fastest way to see which carrier carries the lowest free-time risk on a given lane.
Use the rows below to estimate worst-case free-time exposure before booking, to validate a carrier invoice after the fact, or to drive an automated risk score inside a logistics workflow. Each row is tied to the tariff source it was validated against.
