Disputing Demurrage and Detention Charges: A Practical Guide for Shippers
Understanding the process for disputing demurrage and detention charges is essential when ocean carriers assess penalties for delays beyond your control. Demurrage and detention fees were originally designed…

Under the Federal Maritime Commission (FMC) regulations stemming from the Ocean Shipping Reform Act of 2022 (OSRA 22), shippers possess strong legal tools to challenge improper billing. Challenging these charges successfully requires understanding statutory protections, establishing time-stamped evidence, and enforcing strict procedural deadlines.

Audit Invoices when Disputing Demurrage and Detention Charges
Before evaluating the operational cause of a delay, examine the structure of the invoice itself. Under 46 CFR Part 541, any demurrage or detention invoice must contain specific required data elements to be legally enforceable.

Confirm that the carrier or non-vessel-operating common carrier (NVOCC) included the following details on the billing statement:

Clear start and end dates for allowed free time, along with the precise date the container became physically available for pickup.
The specific rate calculation, including daily tier escalations and tariff or service contract numbers.
Written certification that the billing party’s own performance did not contribute to the operational delay.
Complete contact details and clear instructions on how to submit a formal fee mitigation or waiver request.
Crucially, carriers must issue demurrage or detention invoices within 30 calendar days from the date charges stop accruing. If an invoice arrives on day 31 or later, or omits mandatory regulatory data elements, the billed party is not legally obligated to pay under federal rules.

Build a Time-Stamped Operational Audit Trail
If an invoice meets basic formatting requirements, your dispute shifts to proving that the delay was unpreventable. Carrier disputes succeed or fail based on contemporaneous, verifiable proof rather than post-hoc assertions.

Maintain a digital log for every container move containing the following evidentiary assets:

Screenshots of port terminal reservation systems demonstrating a complete lack of available appointment slots during the free-time window.
Time-stamped GPS data, driver logs, and Equipment Interchange Receipts (EIR) proving drayage trucks were turned away at the gate or faced excessive dwell times.
Written documentation of terminal closures, severe weather holds, or system outages that prevented container retrieval or empty returns.
Logs showing that the terminal refused an empty container return due to lot congestion or mandated an unworkable dual-transaction requirement.

Execute the Formal 30-Day Dispute Protocol
Once you compile your evidence, submit a formal dispute directly through the carrier’s designated dispute portal or billing contact. Billed parties have at least 30 calendar days from the date of invoice issuance to submit a request for mitigation, refund, or waiver.

Cite the specific bill of lading, container numbers, and exact dollar amounts in dispute. Reference 46 CFR Part 541 and attach your time-stamped evidence as numbered exhibits.

The billing party must attempt to resolve the dispute within 30 calendar days of receiving your request. If the carrier denies your claim without adequate operational justification, or fails to respond within the 30-day window, escalate the matter by filing a Charge Complaint or formal petition with the FMC’s Office of Consumer Affairs and Dispute Resolution Services (CADRS).

FAQ
What is the operational difference between demurrage and detention?

Demurrage applies to containers sitting inside the port terminal beyond granted free time. Detention applies to containers held outside the terminal beyond free time before being returned empty to the carrier’s depot.

Can a carrier bill both the importer and the drayage trucker for the same container fee?

No. FMC Part 541 regulations strictly prohibit dual billing. A ocean carrier or NVOCC cannot issue duplicate demurrage or detention invoices to multiple parties for the same shipment.

What happens if a terminal refuses an empty container return due to space limitations?

If a marine terminal or depot turns away an empty container due to capacity constraints, detention fees cannot be legally assessed for that delay, provided you maintain documentation of the refused return.

Are ocean carriers required to pause the clock during weekends and official port holidays?

Free-time calculations depend on the specific tariff or service contract terms, but carriers cannot assess fees for days when the port terminal is completely closed and physically inaccessible for cargo pickup.

How long does an ocean carrier have to respond to a formal demurrage dispute?

Under FMC regulations, the billing party must attempt to resolve a submitted fee mitigation or waiver request within 30 calendar days of receipt.

Cross-Border Trucking Capacity: Securing Mexico-US Routes During Peak Seasons

Nearshoring growth along major manufacturing hubs like Monterrey, Saltillo, and Querétaro has turned cross-border trucking capacity between Mexico and the United States into a scarce resource. When produce harvesting, industrial manufacturing, and retail peak seasons overlap, southbound and northbound freight volumes diverge rapidly. Unprepared shippers face extended border dwell times, equipment shortages, and steep spot market rates.

Managing freight across ports like Laredo, El Paso, and Otay Mesa requires navigating specific operational constraints. Capacity bottlenecks rarely stem from a shortage of highways; they happen at transfer cross-docks, drayage handoffs, and customs clearance points where equipment and driver availability stall.

Mitigating Structural Equipment Imbalances
The fundamental challenge of Mexico-US cross-border lanes is directional imbalance. Northbound shipments carrying manufactured goods, electronics, and produce regularly outnumber southbound shipments carrying raw materials or finished consumer goods. This creates a chronic deficit of standard 53-foot dry vans and temperature-controlled trailers inside Mexico.

To secure capacity during volume spikes, shippers must avoid relying on spot market drayage operators. Establishing dedicated equipment repositioning programs or utilizing door-to-door through-trailer service agreements ensures Mexican drayage drivers have pre-allocated empty trailers waiting at border yards.

Optimizing the Three-Leg Transport Model
Most cross-border freight moves via a three-leg transfer model involving a Mexican linehaul carrier, a localized drayage or border transfer operator, and a US linehaul carrier. Delays on any single leg compound border wait times.

Streamlining this process requires aligning carrier partnerships before peak surges begin:

Validate that your Mexican freight forwarder or logistics provider maintains direct interchanges with authorized B-1 visa drivers and vetted US motor carriers.
Ensure mandatory documentation including the Mexican Carta Portilla complement and US CBP pre-filed entry summaries is fully cleared prior to the truck arriving at the Mexican border facility.
Shift high-volume, non-perishable freight lanes toward intermodal rail networks at key interchange points like Laredo or Eagle Pass to relieve pressure on over-the-road trucking capacity.
Working with specialized cross-border logistics partners prevents physical equipment from idling at transfer yards while administrative disputes are resolved.

FAQ
Why does cross-border trucking capacity tighten so drastically during peak season? Peak retail shipping, agricultural harvest cycles, and automotive production schedules converge simultaneously, creating a surge in northbound freight demand that exceeds available trailer and driver capacity.

What is the difference between direct through-trailer service and transloading? Through-trailer service keeps freight inside the same trailer from origin to destination, avoiding physical handling at the border. Transloading involves offloading cargo at a border cross-dock from a Mexican trailer into a US trailer.

How far in advance should cross-border truckload capacity be locked in for peak season? Shippers should finalize core contract volume allocations and lock in primary carrier lane commitments 60 to 90 days before peak seasonal spikes begin.

What documents are required to prevent truck delays at Mexican and US customs? Trucks require a validated Bill of Lading with the Mexican Complemento Carta Portante, commercial invoices, and a cleared US Customs Entry Summary or Automated Manifest System (AMS) filing prior to border arrival.

Can intermodal rail fully replace over-the-road trucking for Mexico-US shipments? Intermodal rail is ideal for heavy, long-haul freight with flexible delivery windows, but over-the-road trucking remains necessary for time-sensitive, high-value, or temperature-controlled cargo.

5 Essential Steps for Clearing USDA Agricultural Imports at Long Beach

Clearing USDA. Agricultural cargo arriving at the Port of Long Beach faces strict joint oversight from U.S. Customs and Border Protection (CBP) Agriculture Specialists and the USDA’s Animal and Plant Health Inspection Service (APHIS).

A single missing phytosanitary certificate or incorrect treatment protocol can freeze a container on the terminal, generating thousands of dollars in daily demurrage charges or triggering mandatory re-exportation.

Successfully navigating agricultural clearance requires pre-arrival documentation, physical hold coordination, and partner agency sign-offs.

Phase 1: Pre-Arrival & Clearing USDA Documentation
Documentation errors cause the majority of initial agricultural holds. When clearing USDA shipments, importers must assemble and verify all regulatory certificates prior to vessel discharge:

Obtain active USDA APHIS permits (such as PPQ Form 587 for plants or VS Form 16-6A for animal products) tailored to the specific country of origin and botanical or animal species.
Secure the original foreign Phytosanitary Certificate issued by the exporting country’s National Plant Protection Organization (NPPO), ensuring exact match on weights, descriptions, and treatments.
Confirm your ocean carrier submits the Automated Manifest System (AMS) data at least 24 hours prior to foreign loading to avoid manifest discrepancies.
Transmit partner government agency (PGA) message sets through the Automated Commercial Environment (ACE) during initial entry summary filing.
Phase 2: Port Holds & Clearing USDA Inspections

Upon arrival at the Port of Long Beach, CBP Agriculture Specialists evaluate entry data to determine whether cargo requires physical sampling or agricultural examination:

Check ACE status notifications for Agriculture Holds (1A) or Emergency Action Notifications (EAN / Form PPQ 523).
Coordinate drayage to an approved Centralized Examination Station (CES) if CBP orders a full container devanning and inspection.
Ensure wood packaging material (WPM) strictly complies with ISPM-15 international standards, bearing legible stamps on all pallets and dunnage to avoid immediate quarantine.
Phase 3: Quarantine Treatment & Final Release

If inspectors detect actionable pests or prohibited plant residue during the process of clearing USDA cargo, the shipment enters quarantine protocol:

Secure an official USDA-approved treatment order if a fumigation or cold-treatment option is granted on the EAN.
Transfer cargo via bonded, seal-verified transport to a licensed USDA-certified treatment facility near the port complex.
Obtain official USDA sign-off following successful treatment or secondary re-inspection to trigger final electronic release in ACE before returning the container to domestic chassis.
FAQ
What happens if CBP Agriculture Specialists find an actionable pest in my cargo at Long Beach?

CBP issues an Emergency Action Notification (EAN). Depending on the pest classification, you will be given options to treat the cargo at an approved local facility, re-export the shipment, or destroy it under government supervision.

Can USDA-regulated agricultural goods be inspected directly at the terminal quay?

Most detailed agricultural exams occur at a designated off-dock Centralized Examination Station (CES) equipped for devanning, re-cooling, and intensive sampling, rather than at the ocean terminal.

How does non-compliant wood packaging material (WPM) affect cargo release?

Untreated or unstamped WPM triggers immediate separation. CBP can order the re-exportation of the entire shipment if the non-compliant wood cannot be safely separated from the cargo on site.

Who pays for fumigation or quarantine services at the port?

The importer of record bears full financial responsibility for all CES transfer fees, devanning costs, USDA-supervised treatments, and terminal demurrage accrued during holds.

Do fresh produce imports require additional Partner Government Agency filings?

Yes. Beyond USDA APHIS, most fresh food and produce imports require FDA Prior Notice filings and must meet USDA Agricultural Marketing Service (AMS) grade standards.

Clearing FDA Medical Device Import Holds at the Port of Los Angeles

When the Food and Drug Administration places an administrative hold on a medical device shipment at the Port of Los Angeles (POLA), demurrage and detention fees begin accruing immediately. Marine terminals at POLA and neighboring Long Beach enforce strict free-time windows, leaving importers very little time to resolve document mismatches or physical examination requests before container storage costs escalate into thousands of dollars.

Resolving these holds requires a systematic approach: identifying the specific mechanism stalling your entry, matching your technical documentation to FDA records, and submitting targeted data packets directly through the proper electronic channels.

Understanding FDA Hold Classifications at POLA

Medical device entries transmitted through the Automated Commercial Environment (ACE) encounter two primary types of regulatory holds:

1. FDA Examination or Review Hold: The status reflects that "FDA MAY PROCEED" has been withheld. This typically indicates an automated data flag or a manual desk review conducted by compliance officers at the FDA's Los Angeles District import operations office.
2. Notice of FDA Action (Detention and Hearing): This is a formal administrative action issued under Section 801(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act). The notice specifies that the device appears to be adulterated, misbranded, or manufactured in an unregistered facility, triggering a strict response window (typically 10 to 20 business days) before FDA issues a Notice of Refusal of Admission.

Audit Affirmation of Compliance (AOC) Codes

The vast majority of desk-review holds at POLA stem from inaccurate or incomplete Affirmation of Compliance (AOC) codes submitted by customs brokers during initial entry filing. An entry flag occurs whenever ACE transmission data does not match records in the FDA Unified Registration and Listing System (FURLS).

Importers must cross-reference their entry paperwork against four critical identifiers:
• Premarket Submission Number (PMN): Verify that the 510(k), PMA, or De Novo clearance number matches the cleared indications for the device. If the device is 510(k)-exempt, confirm that the broker transmitted the correct exempt product code rather than leaving the field blank.
• Device Listing Number (LST): Ensure the 7-digit listing number corresponds directly to the active commercial distribution record in FURLS.
• Foreign Manufacturer Registration (DEV): Check that the foreign establishment's registration number (FEI) is active and that annual registration user fees (MDUFA) are fully paid for the current fiscal year.
• Device Initial Importer (DII): Confirm that the U.S. entity listed as the importer of record on CBP Form 7501 holds an active Initial Importer registration with the FDA.

When an AOC error is identified, your customs broker must submit an electronic entry correction in ACE or upload revised commercial invoices and device specifications directly via FDA's Import Prior Notice and Entry Review portal (ITACS).

Managing Physical Examinations and Wharf Inspections

If the FDA issues a physical exam hold, the container cannot move into domestic commerce until FDA consumer safety officers complete a physical check. At POLA, cargo may be inspected directly at the marine terminal or transferred under customs bond to a Centralized Examination Station (CES) like Price Transfer or FCL Logistics.

Physical examinations focus on device labeling compliance under 21 CFR Part 801 and Unique Device Identification (UDI) requirements under 21 CFR Part 830:
• Labeling Integrity: Outer packaging, unit cartons, and package inserts must display the manufacturer's name, place of business, adequate directions for use, and required prescription statements (e.g., "Rx only" if applicable).
• UDI Rules: Devices must bear a proper UDI label in both human-readable plain text and automatic identification and data capture (AIDC) format, matched against records in the Global Unique Device Identification Database (GUDID).

If labeling defects are discovered during an inspection, importers can prevent outright refusal by submitting Form FDA-766 (Application for Authorization to Relabel and to Perform Other Action). This formally requests authorization to bring the non-compliant goods into legal compliance under FDA supervision at a designated bonded warehouse.

Assembling a Detention Rebuttal Package

Receiving a formal Notice of FDA Action requires a structured legal and technical response submitted directly to the assigned compliance officer before the hearing date expires.

Your response submission should contain:
• High-resolution photographs of production labels, showing the exact placement of UDI identifiers, lot numbers, and distributor/manufacturer markings.
• Copy of the FDA 510(k) clearance letter or PMA approval order tying the trade name directly to the specific model numbers in the container.
• Device Master Record (DMR) excerpts establishing manufacturing specifications and quality system compliance (21 CFR Part 820).
• Proof of valid foreign site registration and active listing status pulled directly from the public FDA database.

Once the compliance officer reviews and accepts the evidence, an updated Notice of FDA Action showing "MAY PROCEED" will be issued. This release automatically updates CBP systems, lifting the customs hold and allowing final drayage to proceed.

FAQ

What is the difference between a CBP hold and an FDA hold on medical devices?
A CBP hold relates to tariff classification, customs valuation, intellectual property, or general security checks. An FDA hold is a Partner Government Agency (PGA) action based strictly on regulatory compliance under the FD&C Act, such as registration, listing, labeling, or premarket clearance.

Can I move my container out of the Port of Los Angeles while under an FDA review hold?
Importers may request permission to move containers under a CBP conditional release bond to an off-port bonded warehouse or secure facility within the port limits while awaiting FDA admissibility decisions, preventing severe terminal demurrage charges.

What happens if an FDA medical device hold is ignored?
If you fail to respond to a Notice of FDA Action before the specified deadline, the FDA will issue a Notice of Refusal of Admission. Once refused, the merchandise must be exported or destroyed under CBP and FDA supervision within 90 days.

How long does the Los Angeles FDA District office take to review submitted entry documentation?
Electronic documents submitted through ITACS are typically processed within 2 to 5 business days, though complex inquiries involving laboratory testing, physical wharf exams, or formal detentions may take 1 to 3 weeks depending on port volume.

Can a foreign manufacturer contact the FDA directly to resolve an import hold?
While foreign manufacturers can provide technical documentation, communications regarding import holds are generally coordinated through the U.S. Designated Agent, the Initial Importer of record, or the licensed customs broker managing the ACE entry.
