Most freight damage is not bad luck. It follows a small number of predictable causes, and most of them can be traced back to decisions made at the dock before the truck ever leaves. Claims can recover some of the loss, but a claim never fully replaces a customer’s lost time, a missed sale, or a production line waiting on parts.
Here are ten of the most common causes of freight damage and the practical steps that prevent them.
1. Overhang on the pallet
When cartons hang over the edge of a pallet, the overhanging part has no support underneath. Corners crush, cartons tear when the pallet is moved, and forks or neighboring pallets hit the exposed boxes.
Prevention: Choose a pallet size that fits the carton footprint, keep cartons flush with or slightly inside the pallet edge, and redesign the stacking pattern if cartons do not fit. For pallet footprints and trailer fit, see pallet sizes and how many fit in a trailer.
2. Poor stacking patterns
Column stacking puts box corners directly on top of each other, which gives strong vertical compression strength but can be less stable side to side. Interlocking patterns improve stability but can reduce compression strength. Random stacking, where cartons of different sizes are piled wherever they fit, gives the worst of both.
Prevention: Put heavier cartons on the bottom, keep the top surface flat, and choose a stacking pattern based on the carton strength and how the pallet will be handled. Use tier sheets or corner boards when cartons are weak.
3. Weak or damaged pallets
A broken deck board or cracked stringer can fail under load, especially when a forklift lifts it or another pallet is stacked on top. Reused pallets vary widely in quality.
Prevention: Inspect pallets before building loads, reject broken ones, and match pallet strength to the weight it carries. Heavy or high-value freight deserves a pallet in good condition.
4. Load shifts in transit
Braking, acceleration, turns, and rough roads all create forces that push freight around a trailer. Unsecured freight slides, tips, and collides with other freight or the trailer walls.
Prevention: Load tightly, block gaps, and secure the load with straps, load bars, or other devices. For trucks operating in the United States, federal cargo securement rules are found in 49 CFR Part 393, Subpart I. Shippers and carriers should both understand who is responsible for securement on a given move.
5. Lack of bracing and dunnage
Even a tightly loaded trailer often has voids: at the rear, between pallet rows, or above shorter pallets. Freight shifts into those voids.
Prevention: Fill voids with dunnage such as airbags, foam, or lumber bracing. Use load bars at the rear of partial loads. Brace tall or top-heavy items so they cannot tip.
6. Moisture and water exposure
Water damage can come from roof leaks, wet trailer floors, condensation inside containers, rain during loading, or freight left outside on a dock. Cardboard loses much of its strength when wet, so moisture damage often leads to crushing as well.
Prevention: Inspect trailers and containers for light leaks and wet floors before loading, keep freight covered during loading, and consider desiccants or moisture barriers for ocean containers. Stretch wrap helps but does not make a pallet waterproof.
7. Forklift handling
Forks that enter at an angle, pallets that are pushed instead of lifted, and loads that are raised too fast or set down too hard cause a large share of damage at docks and warehouses. Fork punctures are a common sign.
Prevention: Make sure pallets have clear fork openings, train operators on handling, and use clear labeling for orientation. For freight that cannot tolerate forklift contact, specify alternate handling and confirm the carrier and facilities can provide it.
8. LTL rehandling
Less-than-truckload freight is often loaded, unloaded, and reloaded at several terminals before delivery. Every handoff is another chance for damage, and freight shares space with other shippers’ cargo of different shapes and weights.
Prevention: Package LTL freight to survive multiple handlings, avoid shapes that are hard to stack around, and consider whether a full truckload, a volume shipment, or a dedicated move makes more sense for fragile or high-value items.
9. Missing or unclear fragile and handling marks
Workers cannot protect what they do not know is fragile. Labels that are missing, too small, placed on one side only, or covered by stretch wrap do not help.
Prevention: Mark fragile freight clearly on multiple sides, use orientation arrows, add “do not stack” or “top load only” where needed, and put the same handling instructions on the bill of lading. Labels are not a guarantee, but they reduce careless handling and support a later claim.
10. Seal and security problems
A missing, broken, or mismatched seal does not damage freight by itself, but it often signals that a trailer was opened and freight was disturbed, removed, or restacked along the way. It also complicates any claim, because it becomes harder to show where the problem happened.
Prevention: Apply a seal at origin, record the number on the bill of lading, and check it at delivery before the doors open. For more, see trailer and container seals explained.
What to do when damage still happens
Prevention reduces damage but does not eliminate it. When freight arrives damaged:
- Note the damage specifically on the delivery receipt before signing.
- Take clear photos of the freight, packaging, and trailer.
- Keep the damaged goods and packaging until the claim is resolved.
- Report concealed damage promptly once the freight is unpacked.
For the details, see freight damage at delivery and claims and concealed damage claims. Claims against motor carriers for interstate shipments are generally governed by the Carmack Amendment, 49 U.S.C. 14706, and the claim filing regulations in 49 CFR Part 370.
Building a damage prevention habit
As an AI transportation consultant, the first thing I look at is the damage history itself. Patterns appear quickly when claims are sorted by product, packaging, lane, carrier, facility, and type of damage. If most damage involves crushed corners, the fix is stacking and carton strength. If it involves fork punctures, the fix is at the dock. Data analysis, whether in a spreadsheet or an AI tool, turns scattered claims into a short list of fixes.
Start with the biggest pattern, fix it, and measure again. Freight damage prevention is mostly discipline at the dock, repeated every day.
