Shipper Responsibilities in Freight

Shippers carry major responsibilities before a truck ever leaves the dock. From packaging goods that can survive transit to preparing an accurate bill of lading, every step affects the safety of the load, the carrier's liability exposure, and whether freight claims get paid or denied.

Packaging Requirements

The shipper is legally responsible for packaging freight so it can withstand normal conditions of transport. This includes vibration, minor shifting, stacking pressure, and temperature changes. If damage occurs because of inadequate packaging, the carrier has a valid defense under the Carmack Amendment.

Packaging Checklist for Shippers

Pallets in good condition, no broken boards

Stretch wrap tight and covering full height

Boxes sealed, labeled, and not overhang pallets

Fragile items cushioned with foam or padding

Weight evenly distributed across pallets

Stackable items clearly marked or corner-protected

Liquid containers sealed and upright-oriented

Appropriate packaging for temperature-sensitive items

Bad Packaging = Carrier's Best Defense

If a shipper sends freight on broken pallets with loose stretch wrap, and damage occurs in transit, the carrier can argue the "act of the shipper" defense. This is one of five exceptions to carrier liability under the Carmack Amendment. Document packaging condition with photos at every pickup.

Loading and Securement

At many facilities, the shipper's dock workers load the trailer. When that happens, the shipper is responsible for proper weight distribution, load securement inside the trailer, and ensuring the gross weight does not exceed 80,000 pounds (or axle-specific limits).

Weight Distribution

Freight must be loaded so axle weights stay within legal limits. An unevenly loaded trailer creates handling problems and can trigger DOT overweight fines. If the shipper loaded the trailer and the weight distribution is wrong, the driver may need to reposition freight or refuse the load.

Internal Bracing and Blocking

On shipper-loaded trailers, the shipper should brace freight to prevent lateral and longitudinal movement. Load bars, dunnage, and void fillers help keep pallets from shifting during transit. Without proper bracing, freight falls and gets damaged, and carriers may face claims they cannot easily defend.

Shipper Load and Count (SLC)

When the shipper loads and seals the trailer without the driver present, the BOL should be marked "SLC" or "Shipper Load and Count." This notation establishes that the driver did not verify the load contents and shifts some responsibility back to the shipper for count accuracy.

Inspect What You Can See

Even on SLC loads, look through the trailer doors before the shipper closes them. Count visible pallets, check for leaning stacks, and note anything unusual. Write "SLC - driver observed [X] pallets from door" on the BOL. This small step has saved many carriers from paying shortage claims.

BOL and Documentation Duties

The shipper is responsible for preparing an accurate bill of lading before the carrier departs. This document serves as a receipt, a contract, and the primary evidence in any freight claim. Errors on the BOL create problems for everyone.

Cross-Check BOL Against Rate Con

Drivers and dispatchers should always compare the rate confirmation with the BOL before leaving the shipper. Mismatched addresses, weights, or commodity descriptions should be resolved immediately. Do not leave with conflicting paperwork.

Hazmat Compliance

When shipping hazardous materials, the shipper's responsibilities become significantly more serious. Under 49 CFR, the shipper must classify, package, mark, label, and describe hazmat correctly on all shipping papers. The carrier relies on the shipper's declaration to know what they are hauling and how to handle it.

Classification

Shipper must identify the hazard class, UN number, and proper shipping name for every hazardous item.

Packaging

Hazmat must be in UN-specification packaging appropriate for the hazard class. Non-compliant packaging is a serious violation.

Labeling and Marking

Each package must have the correct hazard label and marks. The shipper also determines what placards the carrier must display.

Emergency Contact

Shipping papers must include an emergency response phone number available 24/7 in case of spills or accidents.

When Shippers Are Liable for Freight Damage

Under the Carmack Amendment, carriers are strictly liable for cargo damage. But there are five recognized exceptions where the carrier is not liable, and two of those relate directly to shipper failures.

Act of the Shipper

If the shipper improperly packaged, loaded, or braced the freight, and that failure caused the damage, the carrier has a defense. This is the most commonly used shipper-related defense in freight claim disputes.

Inherent Nature of the Goods

Some products are inherently prone to damage. Produce that spoils naturally, live plants that wilt, or volatile chemicals that react to temperature changes. If the shipper did not disclose special handling needs, the carrier may not be liable.

Photos Are Your Best Insurance

Take timestamped photos of freight condition and packaging at every pickup. If you see broken pallets, loose wrap, leaning stacks, or wet boxes, photograph them and note the issues on the BOL before signing. This documentation is the foundation of any successful "act of the shipper" defense.

How We Protect Our Carriers at Shipper Facilities

Pickup is one of the highest-risk moments for any load. Our dispatch team has developed processes to ensure our carriers are protected when dealing with shippers.

We train drivers on inspection protocol

Before dispatching a first load, every carrier receives our pickup inspection checklist. It covers what to look for, how to document issues, and when to call us before signing the BOL.

We flag known problem shippers

Over thousands of loads, we have identified shippers with chronic packaging issues, inaccurate BOLs, and excessive detention times. We warn our carriers before they accept loads from these facilities.

We support freight claim defense

When a freight claim is filed, we help gather the BOL notes, photos, and seal records that prove the shipper's responsibility. Proper documentation at pickup has helped our carriers successfully defend against many claims.

We Protect You at Every Pickup

Our dispatch team verifies BOLs, tracks shipper performance, and helps defend against freight claims. Let us handle the details.
