Carmack Amendment Basics Every Shipper Should Understand

When freight is lost, damaged, or delayed during transit, one question immediately comes to mind: who is legally responsible? For truck shipments that cross state lines in the United States, the answer is often found within a federal law many shippers have heard of but few fully grasp—the Carmack Amendment. Understanding its basics can help you protect your freight, avoid costly surprises, and handle claims more effectively.

This article will explain the core principles of the Carmack Amendment. We will cover its purpose, what a shipper must prove to make a claim, common carrier defenses, and why having an expert logistics partner is essential for navigating these rules.

What is the Carmack Amendment?

The Carmack Amendment is a federal statute that creates uniform rules for carrier liability when goods are moved interstate by a motor carrier. In simple terms, it defines:

• When a motor carrier is responsible for loss or damage.
• What a shipper must prove to recover damages.
• The required timeline for filing claims and lawsuits.

The primary purpose of this law is to create consistency and predictability in freight claims, removing the confusion of dealing with different state laws.

What Carmack Covers (and What It Doesn't)

Knowing whether the Carmack Amendment applies is the first and most critical step in evaluating a claim. The law generally applies when:

• The shipment moves between states (interstate).
• The carrier is a licensed motor carrier.
• The loss or damage happens while the freight is in the carrier’s possession.

However, Carmack does not automatically apply to every situation. It typically excludes:

• Intrastate shipments (shipments that stay within one state).
• Certain international or multimodal moves.
• Shipments where liability has been lawfully limited by a contract.

What a Shipper Must Prove Under Carmack

To establish a valid claim, a shipper must prove three key elements. This is known as making a prima facie case. The shipper must show:

1. The freight was given to the carrier in good condition.
2. The freight was delivered in a damaged condition—or not delivered at all.
3. The amount of the actual loss or damage.

Once these three points are established, the legal burden shifts to the carrier. The carrier must then prove that the loss was not their fault and was instead caused by one of the five recognized legal exceptions.

Common Carrier Defenses Shippers Should Know

Even when a shipper presents a solid claim, a carrier is not automatically liable. Under the law, carriers can use five specific defenses to argue they are not responsible for the loss. These defenses are:

• Act of God: An unforeseeable event of nature, such as a tornado, flood, or lightning strike.
• Public Enemy: An act of a hostile military or terrorist organization.
• Act of the Shipper: An error made by the shipper, such as improper packaging or incorrect loading.
• Public Authority: A government action, such as a road closure, trade embargo, or freight seizure by law enforcement.
• Inherent Vice: The natural tendency of the goods to spoil, decay, or break down without any external fault, like fresh produce wilting.

Carriers often cite these defenses, especially when shipment documentation is incomplete or unclear.

Why Documentation Matters More Than You Think

Carmack claims are frequently won or lost based on the quality of documentation. Clear and consistent records are your best tool for proving a claim and challenging a carrier’s defense. Key documents include:

• Bill of Lading (BOL): This must show the freight was in good condition at pickup. A clean BOL is crucial.
• Proof of Delivery (POD): Any damage or shortage should be noted on the POD at the time of delivery.
• Photos and Inspection Reports: Visual evidence of the freight's condition before and after transit can be invaluable.
• Timely Written Notice: Formal written communication about the damage is required to initiate the claim process.

Missing or inconsistent documentation can significantly weaken an otherwise valid claim, giving carriers a reason to deny liability.

Strict Time Limits Are Often Overlooked

The Carmack Amendment imposes strict deadlines that shippers must follow. Failing to meet them can prevent you from recovering any compensation, regardless of how strong your claim is.

• Filing a Claim: You must file a written claim with the carrier within nine months of the delivery date (or the expected delivery date for lost freight).
• Filing a Lawsuit: If the carrier denies your claim, you generally have two years and one day from the date of the denial letter to file a lawsuit.

These deadlines are firm. Missing them can mean losing your right to recovery entirely.

How an Experienced Logistics Team Protects Shippers

While the Carmack Amendment provides a framework, applying it to real-world situations can get complicated. Factors like contractual liability limits, third-party involvement, and disputes over loading responsibility can quickly turn a straightforward claim into a complex legal issue.
