We request a waiver of the charges on demurrage/detention invoice EX-20413 dated 2026-09-21 for $600.00, container EXLU2345630, B/L EXLU20413.

This request is made within the period allowed by 46 CFR 541.8(a).

The invoice does not meet the requirements of 46 CFR part 541:

1. No URL, QR code, or other digital means pointing to a public page that describes what a request must contain: 46 CFR 541.6(d)(2).
2. No statement that the billing party's performance did not cause or contribute to the charges: 46 CFR 541.6(e)(2).

Under 46 CFR 541.5, failure to include any of the required minimum information in a demurrage or detention invoice eliminates any obligation of the billed party to pay the applicable charge.

Please confirm in writing that the demurrage and detention charges on invoice EX-20413 are cancelled and that no amount is due for them. Under 46 CFR 541.8(b), a billing party must attempt to resolve such a request within thirty (30) calendar days of receiving it.
