For many logistics managers and shipping coordinators, a pallet is often viewed as a commodity: a simple wooden platform designed to move goods from point A to point B. However, in the world of industrial manufacturing and aerospace logistics, the "simple" pallet is actually a critical piece of engineered equipment.
Selecting the wrong pallet design does more than just increase your shipping costs; it introduces significant risks to your cargo, your personnel, and your international compliance standing. Whether you are shipping heavy machinery from Charleston or sensitive electronics from Taylors, avoiding common procurement mistakes is essential for maintaining a lean and safe supply chain.
This guide outlines the most frequent errors businesses make when ordering custom wood pallets and how you can optimize your specifications to protect both your product and your bottom line.
1. The "GMA is Enough" Myth for Industrial Loads
One of the most frequent mistakes is defaulting to the standard 48" x 40" GMA (Grocery Manufacturers Association) pallet for heavy industrial equipment. While the GMA pallet is the backbone of the retail and consumer goods industry, it is rarely the optimal choice for specialized industrial cargo.
The Problem with Footprint Mismatch
Industrial components often have unique dimensions. If your product is 50 inches long and you place it on a 48-inch GMA pallet, you create two inches of overhang. This overhang leaves your product vulnerable to impacts during transit and prevents secure blocking and bracing. Conversely, if your product is significantly smaller than the pallet, you are paying to ship "air" and wasting valuable trailer space.
Weight Distribution and Point Loading
GMA pallets are designed for evenly distributed loads, such as stacked boxes. Industrial cargo often features "point loads": heavy, concentrated weight on a small surface area, like the feet of a machine. Without custom wood pallets designed with reinforced stringers or thicker deck boards, a standard pallet can deflect or snap under the pressure of a point load, leading to catastrophic failure in the middle of a transit lane.

2. Forgetting to Account for Pallet Jack Entry Height
A pallet that cannot be moved is a liability. It is a common oversight to design a pallet based solely on the cargo's weight and dimensions without considering the equipment that will handle it.
Standard vs. Low-Profile Jacks
While most forklifts can handle a variety of entry heights, manual pallet jacks are much less forgiving. A standard manual pallet jack typically requires a minimum clearance of 3.5 inches to enter the pallet and at least 7 inches of clearance to lift it effectively.
If your custom design uses 2-inch stringers or features a bottom deck configuration that blocks the wheels of a pallet jack, your warehouse team will be unable to move the shipment without a forklift. In many delivery scenarios: such as job sites or retail centers without a loading dock: this can result in rejected shipments and costly redelivery fees. Always specify your handling equipment requirements during the design phase.
3. Ignoring ISPM-15 Requirements for Cross-Border Shipments
Compliance is not optional. A single pallet without the proper certification can result in your entire shipment being quarantined, turned back at the border, or even destroyed by customs officials.
The Canada and Mexico Oversight
A frequent misconception among South Carolina manufacturers is that shipments to Canada or Mexico are "domestic-adjacent" and do not require heat treatment. Under the International Standards for Phytosanitary Measures No. 15 (ISPM-15), virtually all solid wood packaging crossing international borders must be heat-treated and stamped.
This rule applies to:
- Custom wood pallets
- Custom shipping skids
- ISPM-15 export crates
- Dunnage, blocking, and bracing material
Even if you are only shipping across the border to Ontario or Monterrey, your wood must be heated to a core temperature of 56°C for 30 minutes to kill wood-boring pests. At Upstate Packaging Solutions, we ensure every export-bound pallet carries the recognized IPPC mark, ensuring your freight moves through customs without delay.

4. Over-Specifying: Paying for a "Tank" When You Need a "Truck"
On the opposite end of the spectrum is the mistake of over-engineering. Many companies use "legacy specs": designs created 10 or 15 years ago for products they no longer manufacture: and continue to pay a premium for features they don't need.
Hardwood vs. Softwood
While oak and other hardwoods offer incredible strength, many industrial loads can be safely supported by Southern Yellow Pine or other softwoods. Softwood is generally more cost-effective and lighter, which can reduce your overall freight spend. If your pallet is only intended for a single trip, using high-grade hardwood may be an unnecessary expense.
Material Grade Optimization
Does your pallet need to be furniture-grade? Probably not. Specifying "clear" wood (wood without knots) for a shipping skid is a common form of over-specification. Industrial-grade lumber is perfectly suitable for most shipping applications and offers the same structural integrity at a fraction of the cost. Our team works with logistics managers in Columbia and Summerville to audit their current specs and identify areas where they can save money without sacrificing safety.
5. Failing to Match the Pallet to the Racking System
How your pallet is stored is just as important as how it is shipped. If your warehouse utilizes selective racking or push-back racking, the pallet design must account for "span."
A pallet that is strong enough to sit on a flat floor may bow or fail when suspended between two rack beams. This is known as deflection. If your pallet will spend time in a rack, it must be designed with the correct number of bottom deck boards and stringer placement to distribute the load across the beams. Failure to account for racking can lead to workplace safety hazards and damaged inventory.

Conclusion: Partnering for Pallet Optimization
The pallet is the foundation of your entire logistics operation. Avoiding these common mistakes: from the "GMA myth" to ISPM-15 oversights: requires a consultative approach to packaging design.
