What Is the Maximum Pallet Height in Different Shipping Scenarios?
Maximum pallet height varies by how and where you’re shipping—knowing the right limit helps you avoid rejections and fees.
If you’re shipping through standard freight services, the typical pallet height limit is 72 inches, including the pallet itself. This size works for most general goods and helps keep handling smooth across carriers.
For LTL shipments, carriers often accept up to 84 inches, but it’s not guaranteed. Some impose surcharges or require rewrapping if your load exceeds the dock height. You should always confirm with the logistics provider before dispatch.
In FTL shipments, you get more flexibility. Most carriers allow loads up to 96 inches, sometimes even 100 inches, especially when using high-cube trailers. Just ensure the height doesn’t interfere with door clearance or stacking safety.
If you’re delivering to Amazon fulfillment centers, they have stricter policies. The maximum pallet height is 72 inches when using Amazon-partnered carriers. Anything above that will be rejected or repacked at your expense.
For container export, keep in mind the inner height of a 40-foot HQ container is around 2.7 meters (about 106 inches), but practical stacking usually stops at 95–100 inches to allow safe loading and unloading.
Always include pallet height in your calculations—don’t overlook those 5.5–6 inches of base height, especially when aiming for ceiling limits.
What Are the Industry Standards and Safety Regulations for Stacking Height?
Standards help define what’s safe, what’s allowed, and what could get your load rejected or penalized.
ISO and Global Guidelines
The ISO 8611 standard defines how to test pallets under stacking loads. Most ISO-compliant plastic pallets support high stacking if loads stay within rated static limits. For example, a full-perimeter base pallet might support stacking up to 4–5 levels, depending on weight and surface area.
OSHA Safety Expectations
In the U.S., OSHA doesn’t set a fixed stacking height, but it emphasizes stability. That means:
- Stacks must not lean or tilt
- Pallets must be in good condition
- No overhanging loads or unbalanced placement
If it looks unstable, it’s considered unsafe—regardless of height.
GMP and Food-Grade Environments
In food and pharma storage, GMP rules require pallets to allow easy cleaning and avoid contamination risks. Stacks are usually kept below 1.6–1.8 meters, especially for open or unpackaged goods. Also, pallets must not block airflow or lighting.
Buyer or Carrier-Specific Policies
Some retailers like Walmart or Amazon enforce strict pallet specs, including height caps, wrapping methods, and labeling rules. If you’re supplying to these buyers, always check their logistics manual—even a few inches off can cause rejection.
Practical Tips for Safe and Efficient High Stacking
Stacking high doesn’t have to mean stacking risky—small choices in pallet type and loading method can make a big difference.
Start with choosing the right base. If you plan to stack above 2 meters, use stackable plastic pallets with a full perimeter or rackable bottom. These offer better load transfer and reduce warping under pressure.
Use stretch film or strapping to secure each layer. For unstable goods, corner protectors or interlayer pads help distribute weight evenly. Never rely on gravity alone for vertical stability.
Avoid mixing pallet types in a stack. For example, don’t place a lightweight nine-leg pallet under a full heavy-duty load. The lower unit may collapse or shift.
If you’re working in a high-bay warehouse, make sure your forklift tines match the pallet entry height. Tilting loads at height is a common cause of topples—check entry clearance before every lift.
Want better stacking results in cold or humid environments? Choose vented plastic pallets. They allow airflow, help keep goods dry, and reduce slippage between layers.
Finally, always verify your stacking plan matches your pallet’s rated static load. Exceeding the limit—even if the stack “looks stable”—is one of the fastest ways to damage product and lose trust from your end customer.
