Where the money leaks

Four billing traps, all written into federal rules.

Most D&D that should never be paid falls into one of these. Each has a citation, and each is checkable on every invoice.

  1. § 541.7(a)

    Invoices issued after 30 days

    Issued day 41

    Charges stopped on August 19. The invoice arrived dated September 29. A billing party that misses the 30-day issuance window cannot require payment, yet late invoices still get paid out of habit.

  2. § 541.5 / § 541.6

    Missing required data elements

    4 of 20 missing

    No container availability date. No certification that the carrier's own performance did not contribute. Omit any of the 20 elements and the obligation to pay disappears.

  3. § 545.5 / § 41102(c)

    Demurrage during gate closures

    3 blocked days

    The terminal closed for weather on two charged days and offered zero import appointments on a third. Demurrage that cannot prompt a pickup is not serving its incentive purpose.

  4. § 545.5

    Per diem while empty returns were refused

    4 refused returns

    The line's own designated return terminal stopped taking 40-foot high cubes. The truck had the empty, the clock kept running, and the invoice billed every day of it.

How recovery works

The 30-day clock

Every day you wait brings you closer to forfeiting the claim.

Three 30-day windows govern every invoice. ATAHSKIA files inside the second one, every time.

  1. Day 0

    Charges stop accruing

    Container out-gated or empty returned. The billing party's clock starts.

  2. ≤ Day 30

    Invoice must issue

    § 541.7(a): an invoice issued later carries no obligation to pay.

  3. +30 days

    Your relief request window

    § 541.8(a): at least 30 calendar days from invoice issuance to request mitigation, refund or waiver.

  4. +30 days

    Billing party must resolve

    § 541.8(b): 30 calendar days from receipt of your request, unless both sides agree otherwise.

All integrations

Questions logistics and finance teams ask first.

Is an invoice really unpayable if one element is missing?

46 CFR § 541.5 says that failing to include any required minimum information eliminates any obligation of the billed party to pay the charge. ATAHSKIA flags each missing element with its § 541.6 citation so the relief request rests on the regulation's own text.

How long do we have to dispute a demurrage or detention invoice?

Under § 541.8(a) the billing party must give you at least 30 calendar days from the invoice issuance date to request mitigation, refund or waiver. The billing party then has 30 calendar days from receipt to resolve the request. ATAHSKIA tracks both clocks per invoice.

Will disputing damage our relationship with the carrier?

Disputes go out as structured relief requests to the billing party's published dispute contact, citing the regulation and attaching evidence. Billing desks process them like any other credit request. Nothing is sent without your approval, and you can set carrier-specific rules for tone and routing.

Does ATAHSKIA file complaints with the FMC for us?

No. ATAHSKIA prepares the charge complaint dossier under 46 U.S.C. § 41310, and you (or your counsel) submit it. ATAHSKIA is audit and dispute-preparation software, not a law firm, and does not represent anyone before the Commission.

What does the free 12-month audit cost?

Nothing upfront. Send a year of paid and open D&D invoices; we return a recovery opportunity report within 48 hours. If you pursue recoveries on historical invoices, a success fee applies only to amounts actually credited or refunded.

Which charges are in scope?

Ocean carrier and marine terminal operator demurrage, detention and per diem on US imports and exports, including NVOCC invoices to their own customers. Charges invoiced before OSRA 2022 took effect on June 16, 2022 fall outside the charge complaint process.
