A carrier’s lien is the legal right of a carrier to retain possession of cargo, or sometimes shipping documents tied to that cargo, until freight and other agreed charges are paid. In international shipping, it can help secure payment for transportation-related amounts that are due under the contract of carriage. Its scope depends on the governing contract and applicable law.
How it works
The lien usually applies only while the carrier still controls the goods or documents; once release occurs, the leverage is often lost. Depending on the shipment and contract language, the claim may extend beyond ocean freight to related charges such as storage, demurrage, detention, or documented advances, but not every charge is automatically covered.
Practical limits
Importers and exporters should review booking terms, bills of lading, and credit arrangements carefully, because lien rights can vary by mode of transport and jurisdiction. A carrier generally cannot use a lien to resolve unrelated disputes over damaged cargo or service complaints unless the contract or law clearly allows it. For example, if an importer fails to pay assessed freight charges, the carrier may refuse to release the container until payment is made or the dispute is otherwise resolved.
