How to Pack Large and Heavy Shipments

For shipments weighing 50 kg or more, these considerations become even more important. Services such as DHL Heavy Weight Express are specifically designed for larger and heavier freight, combining specialist handling with the speed and reliability of DHL's integrated Express network.

Even the best shipping solution, however, depends on one essential factor: preparing your shipment correctly. Poor packing remains one of the most common causes of damage, delays, unexpected surcharges, and shipment claims.

This guide explains how to pack large and heavy shipments properly. You'll learn how to choose the right pallet, secure your freight, use protective packing materials, apply shipping labels correctly, and avoid common packing mistakes that can lead to delays or additional costs.

What Qualifies as a Large or Palletized Shipment?

Not every shipment can move through a standard parcel network. As goods become larger, heavier, or more difficult to handle, they require different packing methods and transportation solutions to keep them protected throughout their journey.

Large Items

These are goods whose dimensions make them unsuitable for standard parcel handling. Common examples include furniture, industrial machinery, exhibition displays, and oversized replacement parts.

DHL Express generally classifies shipments as large when two dimensions exceed 800 mm or when one dimension exceeds 1,200 mm.

Heavy Items

Heavy items exceed typical package weight limits and require specialized handling.

As a general guideline, individual pieces weighing more than 30 kg often require lifting equipment or additional support for safe handling..

For international shipments weighing 50 kg and above, DHL Heavy Weight Express is specifically designed to transport heavier freight. The service supports individual palletized pieces weighing up to 1,000 kg and total shipment weights of up to 3,000 kg.

Palletized Goods

Palletizing allows multiple boxes or bulky items to be transported as a single, stable shipment.

It improves handling efficiency while helping protect goods throughout the shipping journey.

When Should You Move from Parcels to Palletized Shipping?

Palletized shipping is usually the better option when:

• You're shipping multiple boxes to the same destination.

• Your goods have irregular shapes.

• You're transporting fragile or high-value products that require greater stability.

• The load is too heavy to be lifted safely by hand.

DHL Heavy Weight Express supports shipments weighing between  50 kg and 3,000 kg, with individual palletized pieces of up to 1,000 kg.

The Challenges of Shipping Large and Palletized Freight

Shipping goods on a pallet isn't simply a larger version of parcel shipping. Larger and heavier shipments come with additional handling, compliance, and transportation requirements that can affect both costs and delivery times.

Some of the most common challenges include:

• A higher risk of damage due to the weight of the shipment, movement during transit, and the use of forklifts or other handling equipment.

• Stricter handling requirements, including load stability, pallet compliance, and forklift accessibility.

• Additional charges for overweight, oversized, or non-stackable freight.

• Customs requirements, such as the use of ISPM-15-compliant wooden pallets for international exports.

• Delays caused by unstable loads, incorrect dimensions, or non-compliant packaging.

Preparing your shipment correctly isn't just about protecting the goods. It also helps maintain compliance, control shipping costs, and improve the overall  customer experience.

Why Proper Packing Matters for Large Shipments

Protects Your Goods Throughout Transit

Proper packing helps protect shipments from impacts, vibrations, and the repeated handling they experience throughout their journey.

Helps Control Shipping Costs

Poor packing can lead to additional charges, rehandling costs, replacement expenses, or even shipment rejection. Reduces Delivery Delays

Unstable loads or non-compliant pallets are more likely to be held for inspection, repacked, or delayed during transportation and customs clearance.

Improves the Customer Experience

Shipments that arrive safely and on time help build customer confidence. Damaged deliveries, on the other hand, can result in claims, returns, and lost business opportunities.

Many shipping issues begin with the wrong foundation. Choosing the right pallet helps keep your freight stable, compliant, and easy to handle throughout its journey.

Pallet Material

Wooden Pallets

Wooden pallets are the most commonly used option thanks to their strength and durability. They're suitable for most types of freight and can be reused multiple times. However, for international exports, they must comply with ISPM-15 heat-treatment requirements.

Plastic Pallets

Plastic pallets are resistant to moisture, easy to clean, and widely used in industries such as food production and medical devices. Unlike wooden pallets, they do not require ISPM-15 treatment.

Cardboard and Composite Pallets

These lightweight pallets are often used for one-way shipments. While they can be a practical option for certain applications, they generally better suited to  lighter loads.

Pallet Size and Load Capacity

Common pallet sizes include the EUR pallet (1200 × 800 mm) and the North American pallet (48 × 40 inches).

DHL Heavy Weight Express supports palletized pieces weighing up to 1,000 kg, with maximum dimensions of 300 × 200 × 160 cm.

Whenever possible, choose four-way entry pallets, which allow forklifts to access the load from any side making handling  more efficient.

Inspect the Pallet Before Loading

Before placing goods on the pallet, check for broken boards, protruding nails, or any damage that could compromise load stability.

If you're using a wooden pallet for an international shipment, make sure the ISPM-15 certification mark is clearly visible.

The way freight is stacked on a pallet has a direct impact on its stability throughout transportation.

Distribute Weight Evenly

Place heavier items at the bottom of the pallet and lighter ones on top. This keeps the center of gravity low and reduces the risk of the load shifting or tipping during handling.

Choose the Right Stacking Pattern

Column stacking is the best option when all boxes are the same size.

For mixed-size cartons, interlocking stacking can provide greater stability.

Avoid pyramid stacking, as it weakens the load and may prevent the shipment from being safely stacked during transport.

Avoid Overhang

Goods should never extend beyond the edges of the pallet.

Overhanging loads are more vulnerable to damage caused by forklifts, warehouse racking, or other freight during transit.

A properly balanced pallet is safer to handle and helps reduce the risk of damage, delays, and additional shipping charges throughout the supping process.

Even a perfectly stacked pallet can become unstable if the load isn't secured correctly.

Stretch Wrap

Wrap the load from the base of the pallet upward, making sure the film also covers part of the pallet itself to anchor the shipment securely.

Apply at least three complete wraps at both the top and bottom, maintaining enough tension to prevent movement during transit.

Strapping

For heavier shipments, use metal or heavy-duty plastic straps to secure the load to the pallet.

As a minimum, apply two straps perpendicular to the pallet base. Taller loads may require additional cross-strapping to provide greater stability.

Corner Protectors

Place corner protectors on the vertical edges before applying the straps.

They help distribute pressure evenly, prevent strap damage, and provide additional support during handling.

Proper load securing isn't optional. Loose or unstable freight remains one of the leading causes of damage in palletized shipping

While the pallet provides stability, protective packing materials help keep the goods themselves safe throughout transportation.

Depending on the shipment, consider using:

• Double- or triple-wall corrugated boxes for heavy or fragile goods.

• Foam inserts, bubble wrap, air pillows, or protective cushioning materials to absorb shocks.

• The H-taping method to reinforce every box seam.

• Custom foam inserts or wooden crates for high-value, delicate, or irregularly shaped items.

The more valuable or fragile the shipment, the more important adequate internal protection becomes.

What Is Dunnage and Why Does It Matter?

What Is Dunnage?

Dunnage refers to the materials used to protect, separate, and stabilize cargo during transportation.

Its purpose is to fill empty spaces, reduce movement, and keep goods secure inside a pallet, crate, or shipping container.

Common examples include inflatable dunnage bags, foam blocks, wooden bracing, kraft paper, and corrugated inserts.

Why Is Dunnage Important?

Even a well-built pallet can suffer damage if products are able to shift during transit.

Dunnage absorbs shocks and vibrations, minimizes movement, and adds an extra layer of protection that helps keep the entire load stable from origin to destination.

Types of Dunnage and When to Use It

Choosing the right dunnage helps keep your freight stable and protected throughout its journey.

Inflatable Dunnage Bags

Ideal for filling empty spaces between pallets or inside containers, helping prevent loads from shifting during transport.

Foam Dunnage

Designed to protect fragile products by absorbing shocks and vibrations.

Wooden Bracing

Recommended for heavy machinery, wooden crates, and irregularly shaped freight that requires additional support.

Kraft Paper and Corrugated Inserts

A lightweight solution for filling voids, reducing movement, and providing additional protection in lighter shipments.

Corner Protectors and Bracing Boards

Help reinforce stacked cartons while protecting straps from damaging the load.

Using the right dunnage can significantly reduce the risk of damage, improave load stability, and help protect shiptments during transit.

Clear and accurate labeling helps your shipment move through the logistics network without unnecessary delays.

Remember to:

• Apply shipping labels and handling instructions to every side and the top of the pallet.

• Include markings such as FRAGILE, THIS WAY UP, or DO NOT STACK, whenever applicable.

• Make sure barcodes remain visible and are not covered by stretch wrap.

• Clearly identify each pallet in multi-pallet shipments (for example, 1 of 3, 2 of 3, and 3 of 3).

For international shipments, ensure that commercial invoices, waybills, and all supporting documentation are complete and accurate. Missing or incorrect paperwork remains one of the most common causes of customs delays.

Common Packing Mistakes to Avoid

Even experienced shippers can make mistakes when preparing large or palletized freight. Some of the most common include:

• Exceeding the pallet's maximum weight capacity.

• Uneven or pyramid stacking that reduces load stability.

• Failing to secure the load properly due to insufficient  stretch wrap or strapping.

• Incorrect labeling or barcodes that are hidden or unreadable.

• Using damaged pallets or wooden pallets that are not ISPM-15 compliant for international shipments.

• Failing to use dunnage, allowing goods to shift during transportation.

Avoiding these mistakes helps reduce damage, prevent delays, and keep shipping costs under control.
