US Import Demurrage vs Detention Container Charges: Logistics Guide Released

Posey International announces the release of a new guide to demurrage and detention, designed to help U.S. importers understand how each container charge arises and how shipments can be planned around free time.

Houston, United States, November 10, 2026 /NewsNetwork/ -- Houston logistics company Posey International has published a new guide to demurrage and detention, two daily container charges that importers often confuse. The guide targets companies shipping through Houston and other U.S. ports and explains how to plan around both fees.

Terminals are built to move containers rather than store them, the guide explains, so each one gets a short grace period known as free time. Posey International traces most charges to planning gaps before the ship arrives, and aims to move that work to the booking stage.

That planning starts with knowing which charge applies, and the company's guide draws the line by location. Demurrage is billed while a loaded container remains inside the terminal after free time ends. Detention applies once it has left and its own free days expire, continuing until it is returned empty.

Both charges can land on one shipment, the company's guide notes, because a single delay tends to carry through. Customs holds, mismatched paperwork, and limited trucking can keep a container at the terminal, and a congested warehouse can slow its return, leaving the importer with two invoices.

"The common thread is coordination," a Posey International spokesperson explains. "Freight, customs, trucking, and warehousing all have to line up, and these charges tend to appear in the gaps between them. We published this guide so importers can spot those gaps before daily fees start."

To close those gaps, the guide recommends filing customs entries before the ship docks, negotiating extra free days, and booking trucks early. For bills that still arrive, Posey International outlines the Federal Maritime Commission's 2024 rule setting 30-day windows for issuing and disputing invoices. A late bill, the company cautions, may not be payable.

The guide draws on Posey International's experience as a 3PL and freight forwarder founded in 1974. The company handles customs brokerage, air and ocean freight, project cargo, trucking, warehousing, cross-border shipping, and customs bonds, operating across Texas, New York, New Jersey, Georgia, California, and Mexico.
