The port at a glance
The Jose D. Leon Guerrero Commercial Port is Guam's single commercial seaport and the supply line for the island's population, its tourism economy and a large US military presence. The Port Authority of Guam is a public corporation of the Government of Guam. Matson accounts for roughly half of the port's cargo volume according to a 2025 credit rating review, and military-related cargo is a significant share. The port also serves as a transshipment point for Micronesian islands.
Guam's trade mix makes D&D classification important. Cargo from the US mainland is domestic trade, while cargo from Asian origins is US foreign commerce. 46 CFR Part 541 governs D&D billed by ocean common carriers and MTOs in foreign commerce, so an Asian import billed by an ocean carrier is squarely within the rules, and a domestic container from the West Coast is generally not.
The most common error is treating all Guam containers the same. Before disputing, check the origin, the bill of lading and who issued the invoice. Then apply the Part 541 elements and windows to foreign commerce invoices, and the carrier's published terms to domestic ones. In both cases, the terminal's availability and hold records are the evidence base.

Where D&D builds up at Guam.
Typhoons and port closures
Typhoon conditions close the port and shut down cargo operations, sometimes for days. Billed days that overlap closure notices are a clear incentive-principle issue for foreign commerce charges.
Trade classification
Domestic mainland cargo and foreign commerce Asian cargo arrive side by side. Classify each invoice before disputing so the right rules are cited.
Infrequent sailings
Limited service frequency means a missed or delayed call pushes cargo and empty repositioning out by a week or more.
Military cargo surges
Military-related cargo is a significant share of volume. Surges can strain yard space and equipment availability for commercial importers.
Transshipment to Micronesia
Boxes moving onward to other islands depend on connecting services. Delays at the transfer should be documented separately from terminal delays.
Free time and disputes at Guam
Free time in Guam comes from the carrier's tariff or your service contract, and terminal storage from the Port Authority of Guam's tariff. Check every foreign commerce D&D invoice for the 20 minimum elements of § 541.6, including the specific tariff rule relied on and the specific dates charged.
Foreign commerce invoices must be issued within 30 calendar days of the date the charge was last incurred (§ 541.7), and you have at least 30 calendar days from issuance to request relief (§ 541.8). Typhoon closures are the clearest Guam example of days when cargo could not be moved, which the FMC's incentive principle in 46 CFR § 545.5 addresses.
ATAHSKIA tags each invoice by trade lane and billing party, audits foreign commerce charges against Part 541, and attaches closure notices to relief requests automatically.
Guam D&D FAQ
Does FMC Part 541 apply to containers shipped to Guam?
It applies to D&D billed by ocean common carriers and MTOs in US foreign commerce, such as imports from Asia. Containers shipped from the US mainland move in domestic trade under a different framework.
Can I dispute demurrage for days the port was closed by a typhoon?
For foreign commerce charges, yes. Days when the port was closed and cargo could not be moved are a focus of the FMC's incentive principle. Attach the closure notices to a relief request within the § 541.8 window.
Who runs the Port of Guam?
The Port Authority of Guam, a public corporation of the Government of Guam, operates the Jose D. Leon Guerrero Commercial Port.
