Direct answer: To dispute a Port Newark demurrage or detention invoice, check it against the required fields in 46 CFR §541.6. If any single required element is missing — the per-day rate schedule, basis for liability, billing-party certification, or dispute contact — you have no legal obligation to pay until a corrected invoice arrives. Submit a written dispute within 30 calendar days of the invoice date, citing each deficient element by CFR subsection and attaching terminal records, appointment logs, or gate closure notices as supporting evidence.
D&D invoices arrive fast. The dollars are large, the language is dense, and most AP teams just pay them. That's exactly what carriers are counting on.
Between April 2020 and March 2025, nine major ocean carriers collected approximately $15.4 billion in demurrage and detention charges from US importers, per the FMC's own data. A material share of those invoices did not meet the FMC's minimum billing requirements. Some arrived late. Some covered days the terminal gate was physically closed. Some billed parties who never touched the container.
If you are holding a Port Newark D&D invoice right now, this is the framework to audit it before you pay a dollar.
What Just Changed: The September 2025 DC Circuit Ruling and the 2026 FMC Follow-Up
What Section 541.4 Said Before It Was Vacated
When the FMC's D&D Final Rule went into effect on May 28, 2024 (89 Fed. Reg. 14330), §541.4 established which parties could lawfully receive a demurrage or detention invoice. It restricted carriers from billing parties who had no contractual connection to the cargo move — most notably, motor carriers and drayage operators who never agreed to absorb those costs.
What the Court Actually Struck Down — and What It Left Intact
On September 23, 2025, the U.S. Court of Appeals for the D.C. Circuit issued its decision in World Shipping Council v. Federal Maritime Commission, No. 24-1088. The court vacated §541.4 as arbitrary and capricious. Specifically, it found the FMC's rationale was internally contradictory: the Commission claimed contractual privity as its governing principle, then categorically excluded motor carriers from billing even where a direct contract existed. The court severed §541.4 from the rest of the rule.
That's the headline. Here is what it missed: one subsection was struck. The rest of 46 CFR Part 541 — invoice content requirements under §541.6, the 30-day issuance deadline under §541.7, and the 30-day dispute window under §541.8 — was not challenged and remains fully in force. The FMC said so explicitly in its own public statement following the ruling. See the FMC official statement on World Shipping Council v. FMC decision.
The 2026 FMC Final Rule: Formal Removal from the CFR
In early 2026, the FMC issued a final rule formally removing §541.4 from the Code of Federal Regulations, responsive to the D.C. Circuit's order. This was a ministerial action to bring the CFR into alignment with the court's ruling. It did not modify, suspend, or affect any other provision of Part 541.
The Practical Impact: Who Can Now Be Billed Is a Contract Question, Not a Regulatory One
With §541.4 gone, no federal regulation specifies who can and cannot receive a D&D invoice. Motor carriers and drayage operators now face billing exposure that is determined entirely by contract — or, where no contract exists, by contested commercial and legal terrain. The FMC may initiate new rulemaking under OSRA 2022 to fill this gap, but no such rule has been finalized as of mid-2026.
For importers and BCOs, the practical impact is smaller: your exposure was always grounded in your contract with the carrier. What protects you today is §541.6 through §541.8 — and those are intact. For a detailed breakdown of what the ruling means for drayage operators, see our piece on the FMC §541 motor carrier detention billing ruling.
The Compliance Checklist: Every Required Field in a Lawful D&D Invoice Under 46 CFR §541.6
Definition — Demurrage vs. Detention: Demurrage is the charge assessed when cargo remains inside the terminal past the free-time period. Detention is the charge assessed when a shipper or motor carrier holds a carrier-owned container outside the terminal beyond the agreed return window. Both are governed by 46 CFR Part 541. They are separate charges and can accrue simultaneously on the same container.
The 46 CFR Part 541 — Demurrage and Detention (eCFR) invoice content requirements took effect May 28, 2024, after OMB approved the information collection under Control No. 3072-0073. Every compliant invoice must contain the following. Under §541.5, if any single element is missing, the billed party owes nothing until a corrected invoice is issued.
Section A — Identifying Information (Container, BOL, Basis for Liability)
- Container number(s) covered by the charge
- Bill of lading number or booking number
- The basis on which the billed party is being held liable — explicit, not implied
Section B — Timing Information (Dates, Free Time, Invoice Date)
- The date free time began and the last free day
- The date(s) on which charges were incurred
- The invoice date (which starts your 30-day dispute clock)
Section C — Rate Information (Per-Day Rate, Tier Schedule, Total Charges)
- The per-day rate at each tier of the carrier's published tariff
- The number of days billed at each rate
- The total dollar amount due
Section D — Contact and Dispute Process Information
- A specific email, phone number, or portal URL through which disputes can be submitted
- Digital means — such as a URL or QR code — directing the billed party to a publicly accessible website explaining what documentation is required to request fee mitigation, refund, or waiver
- Defined timeframes for the dispute process that comply with the billing requirements of Part 541
Section E — Billing-Party Certification (Carrier Did Not Cause the Charge)
This is the most powerful element for dispute purposes. Under §541.6(e), the billing party must certify that its own conduct, or the conduct of its agents, did not cause or contribute to the charge. That certification is directly testable. If your container sat at PNCT because the vessel arrived two days late and your free time was counted from the published arrival date rather than actual cargo availability, the certification is false. Terminal records will show it.
| Required Invoice Element (46 CFR §541.6) | What a Compliant Invoice Shows | What a Non-Compliant Invoice Looks Like |
|---|---|---|
| Container ID and BOL number (§541.6(a)) | Specific container number(s) and BOL or booking reference | Generic "freight charges" or missing container number — non-payable per §541.5 |
| Basis for billed-party liability (§541.6(a)) | States contractual or legal basis linking this party to the charge | No explanation of why this party owes — non-payable per §541.5 |
| Free-time start and last free day (§541.6(b)) | Exact dates shown for free-time window | Missing or shows only the charge start date — non-payable per §541.5 |
| Dates charges were incurred (§541.6(b)) | Day-by-day or date-range breakdown of billed days | Lump sum with no date breakdown — non-payable per §541.5 |
| Per-day rate and tier schedule (§541.6(c)) | Rate per day at each tier, number of days at each tier | Single total figure with no rate breakdown — non-payable per §541.5 |
| Total amount due (§541.6(c)) | Clear final dollar amount | Missing or inconsistent with the rate math — non-payable per §541.5 |
| Dispute contact information (§541.6(d)) | Named contact, email, phone, or portal URL specifically for disputes; plus digital means to access mitigation instructions | General customer service number only, no digital dispute pathway — non-payable per §541.5 |
| Billing-party certification (§541.6(e)) | Explicit written certification that billing-party conduct did not cause the charge | Missing certification or boilerplate without factual attestation — non-payable per §541.5 |
The 30-Day Clocks: How Timing Rules Under §541.7 and §541.8 Work in Your Favor
Clock 1 — Carrier Must Issue Within 30 Days of Last Incurred Charge (§541.7(a))
Under 46 CFR §541.7(a), the billing party must issue the invoice within 30 calendar days from the date the charge was last incurred. Miss that window, and the billed party is not required to pay. Check the postmark or email timestamp against the last billed day. A carrier that takes five weeks to bill you has already forfeited the right to collect.
Clock 2 — You Have 30 Days from Invoice Date to Request Mitigation or Refund (§541.8(a))
Under §541.8(a), you have at least 30 calendar days from the invoice issuance date to submit a written request for mitigation, refund, or waiver. Note "at least" — some carrier tariffs or contracts provide a longer window. Start your clock from the date printed on the invoice, not the date it arrived in your inbox.
Clock 3 — Carrier Must Attempt Resolution Within 30 Days of Your Request (§541.8(b))
Once you submit a timely dispute, the billing party must attempt to resolve it within 30 calendar days of receiving your request. If they go silent, that silence is itself a Shipping Act compliance issue you can raise with the FMC.
NVOCC Pass-Through: The 30-Day Window for Intermediaries (§541.7(b))
If you are an NVOCC that received a D&D invoice and must pass the charge through to your shipper customer, §541.7(b) gives you 30 calendar days from the date you received the underlying carrier invoice — not from the date the charge was originally incurred — to issue your own compliant invoice. This is the timing relief in Part 541 that explicitly benefits intermediaries. Document when you received the carrier invoice; that timestamp is your clock start.
Treat these clocks the way carriers treat yours. Put a calendar alert on the invoice date the moment it arrives. Miss the 30-day dispute window and you have handed the carrier a clean bill.
Port Newark-Specific Dispute Grounds: Terminal Failures That Legally Nullify D&D Charges
The FMC's core policy rationale — stated in the Final Rule preamble and repeated in the FMC Final Rule on Detention and Demurrage Billing Practices — is that D&D charges must incentivize cargo movement. They cannot lawfully punish a shipper for conditions outside their control. That principle is your leverage.
Appointment Denial as a Documented Dispute Ground
Every terminal at Port Newark/Elizabeth — PNCT, Maher, APM, GCT Bayonne, Port Newark Marine Terminal, Port Jersey — runs its own appointment system. If you requested an appointment during your free-time window and the terminal had no available slots, that denial is recorded in the terminal's own system. Screenshot it. A day you could not pick up the container because the terminal would not let you in cannot lawfully be billed as your demurrage.
If you have had a container sit at Port Newark because of appointment failures or chassis problems, see our breakdown of what to do when your container stuck at Port Newark due to chassis or gate appointment failure.
Chassis Unavailability at Maher, PNCT, and Global Terminal
Chassis shortages at Port NY/NJ are most severe at Maher Terminals and Global Terminal. TRAC Intermodal has reported insufficient labor to repair chassis fast enough to meet demand, creating pool-wide shortages that cascade across the entire port complex. If your driver showed up and no chassis was available, get a driver dispatch record and a chassis pool availability log for that date. Both are obtainable and both are direct evidence the delay was not shipper-caused.
Terminal Gate Closures and ILA Holiday Blackouts
ILA holiday gate closures are published in advance in NYTC tariff schedules. A day the terminal gate was physically closed cannot be billed as a demurrage day. Pull the published gate schedule for the billing period and cross it against the days on the invoice. Any overlap is a billing error — not a gray area.
Vessel-Caused Delays and Late Availability Notifications
If the vessel arrived late and your free time was calculated from the published arrival date rather than actual cargo availability, days you had no physical access to the cargo cannot lawfully be billed. Under the carrier's own §541.6(e) certification, the vessel delay contributed to the charge — making the certification false on its face. Document this with the vessel AIS record and the terminal's cargo availability notification timestamp.
Step-by-Step Audit: How to Review Every Invoice Before Paying a Dollar
Step 1 — Pull the Terminal Gate Record and Match It to Billed Days
Log into the terminal portal — PNCT, Maher, APM, and GCT each have one — and download the gate transaction record for the container. Map every billed day against what actually happened: did the terminal have the container available? Was a gate appointment attempted and denied? Was a chassis available? Mark every discrepancy before touching the invoice.
Step 2 — Verify the Invoice Contains All §541.6 Required Fields
Run the invoice against the eight-row checklist above. Note the specific subsection of §541.6 that is violated for each missing or incomplete field. You do not need to prove harm or intent. A missing element equals non-payable under §541.5.
Step 3 — Check the Issuance Date Against the Last-Incurred-Charge Date
Identify the last day of charges on the invoice. Count 30 calendar days forward from that date. If the invoice date falls after that deadline, the invoice is late under §541.7(a) and you are not required to pay.
Step 4 — Cross-Reference the Rate Against the Carrier's Published Tariff
Carrier tariffs are public. Pull the carrier's published demurrage tariff for the relevant container type, size, and terminal for the period covered. Verify that every per-day rate and tier break on the invoice exactly matches the published tariff. Overbilling at a higher tier, or miscounting days within a tier, is not uncommon. If the container is still accruing charges while you sort this out, see our page on port-side cross-dock storage when your warehouse is full.
Step 5 — Flag the Billing-Party Certification and Test It Against Operational Evidence
Read the §541.6(e) certification on the invoice. Then ask: did anything the carrier or terminal did contribute to this charge? Late vessel arrival, late cargo availability notification, terminal system downtime, chassis shortage at the carrier's preferred pool? Any yes is a factual dispute on the certification. Document it with timestamps and terminal records.
How to Write and Submit a Compliant Dispute Letter (With FMC Escalation Path)
What Your Written Dispute Must Include to Trigger the §541.8 Clock
Your dispute letter must do three things: identify the invoice by number and date, cite each deficient element by CFR subsection number, and attach supporting evidence. For factual disputes — appointment denial, gate closure, chassis unavailability — state the specific dates and attach documentation. State the exact dollar amount contested and the grounds for each contested item. Vague disputes do not trigger the §541.8(b) response obligation as cleanly as specific, cited ones.
Sending to the Billing Party: Contact Info Required on Every Invoice
Under §541.6(d), the billing party must provide a specific dispute contact on the invoice itself. Use that contact. Send by email with read receipt, or via the web portal if one is listed, and preserve proof of submission. The date you submit is the start of the billing party's 30-day resolution clock under §541.8(b).
Escalating to the FMC: CADRS and the Formal Charge Complaint Process
If the billing party does not respond within 30 days, you have two FMC channels. The first is Consumer Affairs and Dispute Resolution Services (CADRS), which provides informal, voluntary facilitation — faster and less adversarial. The second is a formal charge complaint filed with the FMC's Bureau of Enforcement, Investigations, and Compliance. Formal complaints go on the carrier's regulatory record. Carriers know this; CADRS often produces a response faster than a formal filing.
What Happens if the Carrier Ignores Your 30-Day Response Deadline
A carrier that receives a timely, documented dispute and fails to respond within 30 days under §541.8(b) is in violation of the Shipping Act. Document the submission date, record the lack of response, and file with CADRS immediately. That failure is a regulatory violation you can cite in your complaint, not a gray area.

Demurrage Rates at Port Newark in 2026: Know the Numbers Before You Negotiate
Current Tiered Rate Structure for Import Containers
At Port Newark in 2026, demurrage fees typically start at $150–$250 per container per day and escalate past $350 per day after the first week. Detention — the separate charge for holding the carrier's container outside the terminal — typically runs $100–$200 per day on its own tiered scale. These two charges can run simultaneously on the same container.
For context on how these charges interact with port congestion patterns, see our overview of Port Newark freight corridor congestion and dwell times.
How Maersk's January 2026 Tariff Update Changed the Math at Newark
Maersk updated its Newark import demurrage tariff effective January 1, 2026, adding $20 per day across all tiers for dry containers, non-operating reefers, SOC, and tanks at Newark terminals. Under the current schedule, a standard 20- or 40-foot dry container is billed approximately $370 per day for days 1–4 after free time expires, rising to $480 per day for days 5–9, exceeding $620 per day for days 10–29, and reaching $725 per day beyond 30 days.
At that rate, a container that sits 14 days past free time accumulates approximately $7,500 in demurrage before detention is factored in. A container at 30 days accumulates more than $14,000. These are not hypothetical figures.
Why Stacking Demurrage and Detention on the Same Container Is Increasingly Common
A container that sits in the terminal past free time accrues demurrage. Once it is picked up, the carrier's equipment clock — detention — starts running. If the trucker cannot return the empty because the terminal is not taking empties that day, detention keeps accumulating. The two charges are legally separate and must be invoiced and documented separately under §541.6. A single invoice that combines demurrage and detention without separate line-item rate schedules has a §541.6(c) deficiency.
After the Dispute: Preventing the Next Invoice With Operational Controls Near Port Newark
Cross-Dock Staging to Beat the Free-Time Clock
The cleanest way to stop a demurrage clock is to pull the container from the terminal before free time expires — even if your final delivery point is not ready. A cross-dock facility near the port lets you stage cargo outside the terminal, breaking the demurrage cycle without requiring your receiver to be ready. Cross-docking near Port Newark to beat the free-time clock costs less than a single week of Maersk demurrage at the current Newark rates.
Chassis Strategy: Why Asset-Backed Drayage Reduces D&D Exposure
Pool chassis dependency is a documented failure point at Port NY/NJ — TRAC Intermodal has reported repair backlogs insufficient to meet demand at Maher and Global Terminal. Every time a driver arrives and leaves without a container because no chassis was available, that is a day of demurrage exposure that requires documentation and dispute. Drayage operators who own their chassis eliminate this single point of failure. That is risk management, not a premium service.
Tracking Last Free Day Across Multiple Terminals
PNCT handles more than 1.7 million TEUs annually, and its ongoing expansion will add another 1.0 million TEUs of capacity. If you are moving volume through multiple terminals — PNCT, Maher, APM, GCT Bayonne — each calculates free time independently using its own gate-in date and tariff schedule. A spreadsheet with invoice date, last free day, and 30-day dispute deadline for every active container is the minimum required to avoid missing §541.8's dispute window.

Frequently Asked Questions
Does the September 2025 court ruling mean I no longer have FMC protection on my D&D invoices?
No. The DC Circuit vacated only §541.4, the section defining who may be billed. All remaining provisions of 46 CFR Part 541 — invoice content requirements under §541.6, the 30-day issuance deadline under §541.7, and the 30-day dispute window under §541.8 — remain fully in force per the FMC's own public statement. Your invoice checklist and dispute rights are unchanged.
What makes a D&D invoice legally non-payable under current FMC rules?
Under 46 CFR §541.5, failure to include any single required minimum information element eliminates the billed party's payment obligation until a corrected invoice is issued. Missing elements include the basis for liability, per-day rate schedule, or billing-party certification. A late invoice — issued more than 30 calendar days after the last charge was incurred under §541.7(a) — is also non-payable regardless of its content.
How long do I have to dispute a Port Newark demurrage or detention charge?
Under 46 CFR §541.8(a), you have at least 30 calendar days from the invoice issuance date to submit a written request for mitigation, refund, or waiver. Once you submit a timely request, the billing party must attempt to resolve it within 30 calendar days under §541.8(b). Set a calendar alert the moment the invoice arrives — missing the window does not eliminate the charge.
Can a denied terminal appointment at Port Newark be used to dispute a demurrage charge?
Yes. The FMC's policy rationale is that demurrage must incentivize cargo movement, not penalize parties for conditions outside their control. A documented appointment request denied due to slot unavailability during your free-time window is strong evidence the delay was not shipper-caused. Screenshot the denial from the terminal portal and reference it specifically in your dispute letter.
Can ocean carriers now bill drayage companies directly for detention after the §541.4 vacatur?
The vacatur removes the regulatory prohibition, so the answer depends entirely on what the contract between the motor carrier and the billing party says. Where no such contract exists, billing a drayage company remains commercially and legally contested territory. The FMC may initiate new rulemaking to address this gap, but no such rule has been finalized as of mid-2026.
What are current demurrage rates at Port Newark and how fast do they escalate?
In 2026, Port Newark demurrage typically starts at $150–$250 per container per day, escalating past $350 after the first week. Maersk's current Newark import tariff — updated effective January 1, 2026 — starts at approximately $370 per day for days 1–4 post-free-time, rises to $480 per day for days 5–9, exceeds $620 per day for days 10–29, and reaches $725 per day beyond 30 days. Early container recovery is critical given that math.
Bottom Line
Most D&D invoices get paid because disputing them looks harder than writing the check. It isn't. The FMC built a specific procedural framework for exactly this, and carriers are required by law to follow it. If the invoice is missing a required field, it is non-payable. If it arrived late, it is non-payable. If the billing-party certification is contradicted by terminal records, you have grounds. Run the audit first. Every time.
