Essential Dimensions In Air Shipments and Weight For Freight Cost

Are you gearing up to request a quote for your next air freight shipment? Knowing the essential dimensions of air shipments isn't just helpful—it's crucial. 

The length, width, height, weight, and count of your cargo can dramatically influence the accuracy of your freight quotes. 

Let's dive into why these dimensions are non-negotiable in logistics and how you can ensure your cargo data sets the stage for smooth shipping.

Standard Container Sizes in Air Freight

‍

Air freight utilizes various ULDs to optimize the loading process, safeguard the cargo, and efficiently use available space. Here are some standard ULD types with their typical dimensions:

• LD3 Containers: Often used on wide-body aircraft, these containers are contoured to fit the aircraft's belly. Standard dimensions are approximately 153 cm x 160.5 cm x 162.6 cm (60.4 inches x 63.2 inches x 64 inches).
• LD6 Containers: Larger than LD3s, LD6 containers also have a contoured design suitable for larger shipments. Typical dimensions are about 307 cm x 213 cm x 193 cm (121 inches x 84 inches x 76 inches).
• Pallets: Standard air freight pallets, such as the PMC or P6P pallet, measure around 318 cm x 244 cm (125 inches x 96 inches) and provide a versatile platform for securing various cargo sizes.

Maximum Dimensions for Air Cargo

While standard containers facilitate most air cargo needs, oversized cargo requires special consideration. The maximum dimensions for air cargo depend significantly on the aircraft type but generally include:

• Height: Up to 3 meters (about 118 inches), especially in cargo-only aircraft or the main deck of a freighter plane with greater height capacity.
• Width and Length: Can vary, with some freighter aircraft accommodating pieces up to 96 inches long and 127 inches wide.

The Importance of Accurate Cargo Dimensions for Quote Requests

Why should you double-check the dimensions and weight of your cargo before requesting a quote? The answer lies in these measurements' impact on pricing and logistical arrangements. Accuracy in cargo dimensions can lead to significantly skewed freight quotes, resulting in unexpected charges upon shipment verification.

For example, underestimating the weight or size of your cargo is a minor oversight. Still, it can cause your shipment to be reclassified or even rejected at the loading point, disrupting supply chains and delivery schedules. 

On the other hand, overestimating can lead to paying for more space and weight capacity than needed, unnecessarily increasing your costs.

Calculating Air Freight Costs

Are you puzzled about how air freight costs are determined? It all revolves around understanding the weights involved in your shipment. The dimensions of air shipments are crucial in calculating the cost of air cargo logistics. 

Let's simplify how gross, volumetric, and chargeable weight affect your shipping expenses, ensuring you're well-prepared when planning your next air freight shipment.

1. Gross Weight

Gross weight, also known as actual weight, encompasses the total weight of your shipment, including the items being shipped and their packaging. This is the straightforward physical weight measured on a scale.

Example Calculation of Gross Weight:

Suppose you are shipping a batch of books. The books weigh 40 kilograms, and the pallet they're packed on weighs 10 kilograms. Therefore, the gross weight of your shipment is:

Books Weight+Pallet Weight=Gross Weight

40 kg+10 kg=50 kg

This measurement is crucial as it is one of the factors that can determine your shipping cost if it is greater than the volumetric weight.

2. Volumetric Weight

Volumetric weight, also known as dimensional weight, accounts for the volume a package occupies in terms of its weight. This is particularly important for light items that take up much space.

Steps to Calculate Volumetric Weight:

• Measure the dimensions of the package (length, width, height).
• Multiply these dimensions to find the cubic volume.
• Divide the volume by a standard conversion factor (6000 cm³ per kg) to find the volumetric weight.

Example Calculation:

Let's say you're shipping a large, lightweight decoration:

Dimensions: 100 cm x 100 cm x 100 cm

Volume: 100×100×100=1,000,000 cm3

To find the volumetric weight:

1,000,000 cm36000 cm3/ kg = 166.67 kg

3. Chargeable Weight: Definition and How It Affects Pricing

Air freight carriers use chargeable weight to calculate shipping costs. It is determined by comparing a shipment's gross and volumetric weights and using the higher of the two. This ensures carriers are compensated fairly for the space and weight capacity a shipment uses.

Determining the Chargeable Weight:

From the examples above, if your shipment's gross weight is 50 kg and its volumetric weight is 166.67 kg, the chargeable weight used to calculate your shipping costs will be 166.67 kg, as it is the higher value.

This method ensures that heavy, dense, and considerable light goods are priced to reflect their impact on the carrier’s resources.
