Shipping heavy machinery is a high-stakes operation. Equipment may be exposed to forklift impacts, vibration, shifting loads, humidity, temperature changes, ocean transit, and repeated transfers between warehouses and carriers. When packaging fails, the result can include damaged equipment, missed production schedules, customer claims, and unplanned repair or replacement costs.
Most packaging failures are preventable. The right combination of a custom skid, crate, internal blocking, bracing, and moisture protection helps protect your cargo, schedule, customer relationships, and bottom line.
This guide explains how to evaluate machinery packaging, select between pallets, heavy duty skids, and custom shipping crates, and determine the protection level your equipment requires.
What Is Machinery Packaging?
Machinery packaging is an engineered protection system designed around the weight, dimensions, geometry, sensitivity, and shipping route of industrial equipment. It is more than a wooden box or platform.
A complete system typically combines:
- A load-bearing platform: A custom pallet or skid that supports the equipment and provides forklift access.
- An enclosure: A crate or partial crate that protects against impact, punctures, contamination, and weather exposure.
- Internal protection: Blocking, bracing, chocks, tie-downs, foam inserts, vibration isolation, and other supports.
- Moisture and corrosion control: Vapor barriers, VCI materials, desiccants, and protective coatings where needed.
- Handling and identification features: Lift points, forklift pockets, center-of-gravity markings, weight information, and orientation labels.
The objective is to prevent the machinery from shifting while also controlling the forces transferred to sensitive components. Proper design can reduce damage risk without adding unnecessary lumber, weight, or freight volume.
Crate vs. Skid vs. Pallet: What Is the Difference?
Each packaging format serves a different purpose. The correct choice depends on how stable the cargo is, how it will be handled, and how much environmental protection it needs.
Custom Wood Pallets
A custom pallet is generally appropriate for lighter or stable cargo that needs a durable platform and reliable forklift access. Pallets usually provide a full or partial deck with runners and support blocks positioned for the load.
Custom pallets may be appropriate when:
- The equipment or product has a broad, stable base.
- The load is relatively light or evenly distributed.
- The cargo does not require a full enclosure.
- Forklift entry is the primary handling requirement.
- The shipment is moving through a controlled domestic route.
A custom pallet can also be designed for oversized or overweight products. It should not be selected solely by matching length and width. Deck construction, runner spacing, load concentration, and handling conditions all affect performance.
Heavy-Duty Skids
A heavy-duty skid is the workhorse of machinery packaging. It is a reinforced, low-profile platform designed to distribute concentrated loads across runners, cross-members, saddles, or other structural supports.
Skids are often the better choice for machinery because industrial equipment rarely distributes its weight evenly. Motors, generators, presses, transformers, pumps, and machine tools may place substantial force on a few feet or mounting points.
A properly designed skid can include:
- Reinforced runners
- Additional cross-members beneath concentrated loads
- Custom saddles or cradles
- Steel plates or brackets
- Bolting points matched to equipment feet
- Forklift pockets and defined lift areas
- Blocking and bracing to control movement
Use a skid when your equipment needs strong base support but does not necessarily require a fully enclosed structure. This may apply to domestic flatbed shipments, oversize freight, or equipment that must remain accessible during handling.
Custom Shipping Crates
A custom shipping crate provides the highest level of physical protection. It typically includes a skid or pallet base, structural framing, side panels, a top, and internal components designed around the equipment.
Crates are commonly used for:
- High-value machinery
- Sensitive electronics and controls
- Long-distance or multimodal shipments
- Ocean freight
- International exports
- Equipment that will be stored outdoors or in uncontrolled environments
- Cargo requiring protection from impact, dust, moisture, or unauthorized access
A useful rule of thumb is: pallets carry boxes, skids carry machines, and crates carry everything else: especially across borders. The final design should still be based on the actual shipment risk rather than a general category.
How to Choose the Right Protection Level
Protection should be proportional to the equipment’s value, fragility, route, handling environment, and storage conditions. Adding materials without addressing the actual risks can increase cost without improving performance.
Level 1: Domestic Basic Protection
A basic domestic package may be sufficient when the equipment is durable, stable, and traveling a short distance by truck.
This level may include:
- A reinforced skid or custom pallet
- Blocking to prevent sliding
- Bracing to control tipping
- Stretch wrap or shrink wrap
- Corner protection
- Basic handling labels
This option is generally not appropriate for exposed precision components, high-value electronics, ocean freight, or shipments that may remain outdoors.
Level 2: Enhanced Domestic Protection
Enhanced domestic protection is appropriate when the equipment has sensitive components, an unusual center of gravity, or a longer and more complex route.
This package may include:
- A full or partial custom crate
- Engineered blocking and bracing
- Foam inserts or cushioning at vulnerable areas
- Bolt-down securement
- Moisture-resistant film
- Defined forklift and lifting points
- Center-of-gravity and orientation markings
This level gives your shipment more protection through transfers, warehouse handling, and temporary storage.
Level 3: Export and Ocean-Freight Protection
Ocean and international shipments require the most comprehensive approach. Cargo may face salt air, high humidity, condensation, stacking pressure, vessel movement, long transit times, and multiple inspections or handling events.
An export-grade package may include:
- A fully enclosed, structurally reinforced crate
- Heavy-duty skids with engineered load distribution
- Blocking, bracing, chocks, and tie-downs
- Vapor-barrier film or sealed barrier bags
- VCI film, paper, or emitters
- Desiccants
- Foam inserts or vibration isolation
- Clearly marked lift points and gross weight
- ISPM-15-compliant solid wood components
The crate must protect the equipment while also fitting the container, trailer, or aircraft handling limits. Packaging design should begin before the freight is booked so the final dimensions and weight do not create avoidable transportation problems.
Moisture and Corrosion Protection
Moisture is one of the most common causes of damage during equipment transportation. Condensation can form when a shipment moves between warm and cold environments, particularly inside a sealed ocean container.
A wooden crate protects against many physical hazards, but it does not automatically protect bare metal, electrical systems, or precision components from humidity. Your protective packaging solutions may need to include:
- Vapor-barrier bags or film
- Heat-sealed seams
- Desiccant packs
- VCI film, paper, or emitters
- Corrosion-inhibiting oils or coatings
- Foam inserts
- Blocking that keeps equipment off the floor
- Bracing that prevents contact with crate walls
Tell your packaging provider whether the equipment contains exposed steel, electronics, sensors, optics, hydraulic systems, or other sensitive components. Also identify whether the shipment could experience outdoor storage, ocean exposure, seasonal temperature changes, or extended warehouse dwell time.
ISPM-15 Export Crates: What You Need to Know
ISPM-15 compliance is essential when solid wood packaging crosses international borders. The standard applies to regulated wood packaging materials such as:
- Solid wood crates
- Pallets
- Skids
- Blocking and bracing
- Dunnage
- Other solid wood components thicker than 6 millimeters
The wood must be treated through an approved process, such as heat treatment, and marked with the official ISPM-15 mark. The mark generally includes the IPPC symbol, country code, producer or treatment-provider code, and treatment code such as HT for heat treatment.
Beginning January 1, 2026, U.S. enforcement of the hyphen requirement applies to the mark format. When the country code and facility code appear on the same line, they must be separated by a hyphen, such as US-12345. Marks must also be permanent, legible, and applied in the format accepted by the applicable plant protection authority.
Noncompliant packaging may result in customs holds, re-export, destruction, separation of the wood packaging, inspection charges, and demurrage. These costs can quickly exceed the original price of properly compliant packaging.
The safest approach is to identify the shipment as an export project before fabrication begins. Confirm that the crate, skid, blocking, bracing, and dunnage will use compliant materials. For current U.S. requirements, review the USDA APHIS wood packaging material guidance.

Five Questions to Ask Before Ordering Machinery Packaging
Before requesting a quote, collect the information your packaging provider needs to engineer the package correctly.
What are the exact dimensions and weight?
Include protrusions, removable components, cables, accessories, and any equipment that will ship with the machine.Where is the center of gravity?
Identify lift points, mounting feet, uneven weight distribution, and whether the equipment is top-heavy or irregularly shaped.What is the shipping route and destination?
Domestic truck transport, air freight, ocean containers, and multimodal export routes have different packaging requirements.How long will the equipment be in transit or storage?
Consider warehouse dwell time, port delays, outdoor storage, seasonal weather, and the possibility of extended delays.What is the equipment’s value and cost of damage?
Compare the packaging cost with repair, replacement, lost production, expedited freight, warranty claims, and customer disruption.
Providing drawings, photographs, handling instructions, and equipment specifications can help your packaging partner avoid assumptions and produce a more accurate design.
The Bottom Line: Machinery Packaging Is an Engineering Decision
Choosing between a pallet, heavy-duty skid, and custom shipping crate should not be based on price or appearance alone. The correct system must support the equipment’s weight, control movement, accommodate handling methods, manage moisture, and meet export requirements when applicable.
