Under section 300105 of the National Motor Freight Classification 100-AA "Filing of Claims" section (a) states "Compliance with regulations. A claim for loss or damage, injury, or delay to cargo will not be voluntarily paid by a carrier unless filed in writing, as provided in subparagraph (b) below, with the receiving or delivery carrier, or carrier issuing the bill of lading...on whose line the alleged loss, damage, injury, or delay occurred, within the specified time limits applicable thereto and as otherwise may be required by law, the terms of the bill of lading or other contract of carriage, and all tariff provisions applicable thereto."

Under section 300120 of the National Motor Freight Classification 100-AA "Acknowledgement and Disposition of Claims" it states "Carrier will acknowledge claim in writing within 30 days after receipt thereof, informing the claimant of identifying number assigned thereto, and will pay, refuse payment, or make a firm compromise offer within 120 days after receipt of claim, except, that if claim cannot be disposed of within this period, carrier will at that time and at the end of each succeeding 60 day period thereafter while claim remains pending, inform the claimant in writing of the reason for failure to conclude claim. The carrier shall indicate in its acknowledgement to the claimant what, if any, additional documentary evidence or other pertinent information may be required by it further to process the claim as its preliminary examination of the claim as filed, may have revealed.

A separately numbered file will be established for each claim filed in accord with the provisions of this tariff. All documents, records and correspondence pertaining to such claim will be identified with this file number."

Under section 300135 of the National Motor Freight Classification 100-AA "Reporting Concealed Damage" it states "When damage to contents of a shipping container is discovered by the consignee which could not have been determined at time of delivery it must be reported by the consignee to the delivering carrier upon discovery and a request for inspection by the carrier's representative made. Notice of loss or damage and request for inspection may be given by telephone or in person, but in either event must be confirmed in writing by mail. If more than fifteen days pass between date of delivery of shipment by carrier and date of report of loss or damage, and request of inspection by consignee, it is incumbent upon the consignee to offer reasonable evidence to the carrier's representative when inspection is made that loss or damage was not incurred by the consignee after delivery of shipment by carrier. While awaiting inspection by carrier, the consignee must hold the shipping container and its contents in the same condition they were in when damage was discovered insofar as it is possible to do so."
