DHL charges extra for long-length parcels because they require special handling, take up more space, and add complexity to logistics. Here’s why:

1. Manual Handling & Processing

Long parcels often cannot be processed automatically on conveyor belts, requiring manual sorting and handling. This increases labour costs and processing time.

2. Space Constraints in Vehicles

Long items take up more space in delivery vans and trucks reducing the number of other parcels that can be transported. This leads to lower efficiency and higher costs per shipment.

3. Safety & Securing Challenges

Long items can be awkward to handle and may require extra securing during transit to prevent damage. Special handling adds to operational costs.

Common Extra Charges for Long Parcels

• Oversize Fee – Applied to parcels exceeding a specific length (e.g., over 120 cm/47 inches).
• Non-Stackable Fee – If an item cannot be stacked, it reduces loading efficiency and incurs extra costs.

Hopefully this provides an insight into why delivery costs can vary so much depending on the items size, shape and length.
