• MINGSUNG INSIGHT | DEMURRAGE & DETENTION Container Demurrage & Detention 2026: A Free-Time Audit and Recovery Playbook for US ImportersFMC's OSRA enforcement gives importers 30 days to dispute D&D charges. Most shippers lose 8–15% of D&D fees they could legitimately recover. Here's the 2026 audit playbook. SOURCE Mingsung International Logistics · BY Paul Liang · UPDATED May 15, 2026 · READ 12 MIN |

FAQ — FIVE QUESTIONS WE HEAR MOST
|
1. The Quiet Margin Leak Most Importers Tolerate
Demurrage and detention charges quietly drain importer margins every quarter. They get paid because they're "standard" — and because disputing them looks like more work than it's worth. In 2026, that math has flipped. The Federal Maritime Commission's (FMC) enforcement of the Ocean Shipping Reform Act (OSRA) 2022 has armed importers with concrete dispute mechanisms.
Most US importers can recover 8–15% of paid D&D fees through structured audit — money that goes straight to the bottom line.
2. The Two Charges, Clarified
| Charge | What it covers | Triggered by |
|---|---|---|
| Demurrage | Container sitting at the port beyond free time | Late pickup from terminal |
| Detention | Container retained outside the port beyond free time | Late return of empty container |
Both can hit the same shipment if pickup is late AND empty return is delayed.
3. The 2026 FMC Compliance Standard
Under OSRA 2022, carriers must:
- Publish demurrage and detention schedules publicly on their websites
- Not apply charges retroactively beyond 30 days after the invoice event
- Provide complete invoice fields: BOL, container number, port of discharge, free time dates, availability date, specific charge dates, rate basis, dispute contact
- Respond to dispute requests within 30 days
Importers also have 30 days to request a refund, mitigation, or waiver after invoice receipt. If any required invoice field is missing, you may not owe the charge at all.
4. The Six-Step Audit Process
| Step 1 — Invoice field check Verify every Part 541 field is present. Missing field = potential full waiver. |
| Step 2 — Free-time math Recalculate including weekends, holidays, and the actual day the container became available (not the discharge day). Carriers sometimes count weekends incorrectly. |
| Step 3 — Pickup/return event timeline Pull terminal gate logs, trucker appointment records, empty return notices. Map the shipment day-by-day. |
| Step 4 — Force-majeure / port-fault check Was there a strike, weather event, port congestion, terminal IT outage, or appointment denial that caused the delay? Legitimate mitigation grounds. |
| Step 5 — Carrier delay check Did the carrier delay BOL release, container availability notice, or release for pickup? Their delays = their cost. |
| Step 6 — Documentation package Receipts, screenshots, appointment denials, terminal notices, gate logs — everything time-stamped. |
5. The Three Most-Recoverable Charge Categories
| Category | Recovery probability | Typical cause |
|---|---|---|
| Appointment denial fees | 60–80% | Terminal couldn't accommodate the appointment slot |
| Empty return chassis split | 50–70% | Chassis pool exhaustion outside importer control |
| Carrier-side BOL delay | 70–90% | Carrier released BOL late; importer free time started incorrectly |
6. The Free-Time Shortening Problem
Steamship lines have shortened the free days they offer, especially during peak season. Empty container return appointments are harder to get at certain ports, making detention almost automatic in some cases.
The structural response — three contract terms to negotiate for 2026:
- Extended port free time ( 7-day target vs 4-day standard)
- Extended per-diem free time ( 5-day target vs 3-day standard)
- Force-majeure carve-outs (port strikes, weather, chassis shortages exempted)
7. The 30-Day Clock You Must Run
- Carriers cannot apply charges retroactively beyond 30 days after the invoice event — if you see a 60-day-old charge appear, dispute on procedural grounds.
- You have 30 days to request refund/mitigation/waiver — set a calendar reminder for every D&D invoice received.
8. Recovery Math at Different Volumes
| Annual import volume | Typical D&D paid | Typical recovery |
|---|---|---|
| $10M | $80–150K | $8–22K |
| $50M | $400–800K | $40–120K |
| $200M | $1.6–3.2M | $160–480K |
9. The 30-Day Importer Reset
| Days | Action |
|---|---|
| 1–7 | Pull last 6 months of D&D invoices, build line-item database |
| 8–14 | Field-by-field invoice audit per OSRA Part 541 |
| 15–21 | Build documentation packages for high-recovery candidates |
| 22–30 | File dispute requests with carriers, track 30-day response window |
10. The 2026 Bottom Line
D&D charges aren't fixed costs. Under OSRA, they're negotiable, disputable, and frequently recoverable. US importers who run quarterly D&D audits routinely recover 5-figure-plus annual margins that would otherwise leak silently. The shift in 2026 isn't whether to audit — it's whether your team has the FMC-compliant framework to do it systematically.
How Mingsung Can Help
Mingsung International Logistics audits client D&D invoices monthly as part of our ocean freight forwarding service for US importers. Our team applies the OSRA Part 541 field-by-field framework, pulls terminal gate logs and appointment records, and files dispute packages within the 30-day window. The audit runs on a no-recovery, no-fee model for most engagements — making it pure margin upside on top of FCL and LCL services from China, Taiwan, and Southeast Asia.
