33 U.S. Code § 2236 - Port or harbor dues
Port or harbor dues may not be levied for the purposes described in paragraph (1)(B) of this subsection after the dues cease to be levied for the purposes described in paragraph (1)(A) of this subsection.
Upon the arrival of a vessel in a harbor in which the vessel may be subject to the levy of port or harbor dues under this section, the master of that vessel shall, within forty-eight hours after arrival and before any cargo is unloaded from that vessel, deliver to the appropriate authorized representative appointed under subsection (a)(6)(C) of this section a tonnage certificate for the vessel and a manifest of the cargo aboard that vessel or, if the vessel is in ballast, a declaration to that effect.
The shipper, consignor, or terminal operator having custody of any cargo to be loaded on board a vessel while the vessel is in a harbor in which the vessel may be subject to the levy of port or harbor dues under this section shall, within forty-eight hours before departure of that vessel, deliver to the appropriate authorized representative appointed under subsection (a)(6)(C) of this section an export declaration specifying the cargo to be loaded on board that vessel.
Port or harbor dues levied under this section against a vessel constitute a maritime lien against the vessel and port or harbor dues levied against cargo constitute a lien against the cargo that may be recovered in an action in the district court of the United States for the district in which the vessel or cargo is found.
