What Is the Carmack Amendment?

The Carmack Amendment, codified at 49 U.S.C. Section 14706, is the federal statute that establishes a motor carrier's liability for loss or damage to freight transported in interstate commerce. Originally enacted as part of the Interstate Commerce Act, the Carmack Amendment provides a uniform national framework for freight claims, preempting most state law claims related to cargo loss or damage. For motor carriers, understanding Carmack liability is essential to managing risk and responding properly to freight claims.

Carrier Liability Under Carmack

The Carmack Amendment creates a regime of strict liability for motor carriers. This means the carrier is liable for cargo loss or damage without the shipper needing to prove negligence. To establish a prima facie claim under Carmack, the shipper must prove three elements:

  1. The cargo was delivered to the carrier in good condition
  2. The cargo arrived at the destination in damaged condition (or did not arrive at all)
  3. The shipper sustained damages in a specific amount

Once the shipper establishes these elements, the burden shifts to the carrier to prove that the loss or damage was caused by one of the recognized defenses.

Carrier Defenses

Carriers can avoid or limit Carmack liability by proving that the loss or damage resulted from one of five recognized common-law defenses:

  • Act of God: Damage caused by natural disasters, extreme weather, or other unforeseeable natural events beyond human control
  • Act of the public enemy: Loss caused by military action or armed conflict (rarely invoked in modern litigation)
  • Act of the shipper: Damage resulting from improper packaging, loading, or labeling by the shipper
  • Act of public authority: Seizure, quarantine, or destruction of goods by government order
  • Inherent nature of the goods: Damage caused by the natural characteristics of the cargo, such as spoilage of perishable goods within normal parameters

The Claims Process

Federal regulations under 49 CFR Part 370 establish minimum requirements for the freight claims process:

Filing a Claim

The shipper or consignee must file a written claim with the carrier within 9 months of the delivery date (or reasonable delivery date for lost shipments). The claim must include:

  • The facts of the loss or damage
  • A specific dollar amount of damages claimed
  • Supporting documentation (bill of lading, delivery receipt, proof of value, inspection reports)

Carrier Response

The carrier must acknowledge the claim in writing within 30 days of receipt and must pay, decline, or make a compromise offer within 120 days. If the carrier cannot resolve the claim within 120 days, it must provide a written status update every 60 days until final resolution.

Litigation

If the claim cannot be resolved, the shipper may file suit in federal or state court within 2 years from the date the claim was denied. The Carmack Amendment provides federal question jurisdiction, allowing cases to be heard in federal court regardless of the amount in controversy.

Liability Limitations

Carriers may limit their liability through properly executed released-value rate agreements. Under a released-value arrangement, the shipper agrees to a maximum liability per pound or per shipment in exchange for a reduced freight rate. For the limitation to be enforceable, the carrier must:

  • Offer the shipper a choice between full-value and released-value rates
  • Obtain the shipper's written agreement to the released value
  • Document the released value on the bill of lading

Carmack and Brokers

An important distinction under Carmack is that freight brokers are generally not liable under the amendment because they do not take possession of the cargo. Liability attaches to the actual carrier that transports the freight. However, brokers may face liability under state law or contract claims if they are negligent in selecting carriers. Shippers should verify carrier safety records through the TruckCodes carrier search before tendering freight.

Practical Implications for Carriers

Motor carriers should implement freight claim management procedures that include thorough documentation of cargo condition at pickup and delivery, prompt investigation of reported damage, clear communication with claimants, and timely claims processing. Carriers with high claim rates should review their operations for patterns such as inadequate load securement, improper temperature control, or deficient driver training. Monitoring your violation history and inspection results can help identify operational issues that may be contributing to cargo claims.
