How to Calculate Dimensional Weight for International

Dimensional weight is an important factor in international shipping as it determines the cost of transporting goods. Knowing how to calculate dimensional weight accurately helps businesses plan and budget for shipping expenses. In this article, we will provide a detailed guide on how to calculate dimensional weight for international shipments from China.

1.Understand Dimensional Weight:

Dimensional weight, also known as volumetric weight, is a theoretical weight value used to assess the amount of space occupied by a package relative to its actual weight. Shipping carriers use either actual weight or dimensional weight, whichever is higher, to calculate shipping costs. This calculation prevents undercharging for large but lightweight package.

2.Measure the Package:

Using a tape measure or ruler, measure the length, width, and height of the package in inches. Ensure accuracy by measuring the outermost dimensions, including any bulges or irregularities. Round each measurement to the nearest whole number.

3.Convert Measurements to Cubic Inches:

Multiply the length, width, and height measurements together to obtain the package’s volume in cubic inches. For example, if the length is 10 inches, the width is 8 inches, and the height is 12 inches, multiply 10 x 8 x 12 to get 960 cubic inches.

4.Apply the Dimensional Weight Calculation Formula:

To calculate the dimensional weight, divide the cubic inch volume by the dimensional weight divisor or factor provided by the shipping carrier. The divisor represents the number of cubic inches equal to one pound (lbs) or kilogram (kg), depending on the carrier.

For example:

  • If the dimensional weight divisor is 166, divide 960 by 166 to get 5.78 lbs.
  • the dimensional weight divisor is 139, divide 960 by 139 to get 6.90 lbs.

Round up the result to the nearest whole number. In these examples, dimensional weight would be calculated as either 6 lbs or 7 lbs, depending on the specific divisor used by the carrier.

5.Compare Dimensional Weight and Actual Weight:

Weigh the package using a calibrated scale to determine its actual weight in pounds or kilograms. Compare the dimensional weight calculated in the previous step with the actual weight. The carrier will use the higher of the two weights to calculate shipping charges.

6.Calculate Shipping Costs:

Once you know whether the dimensional weight or actual weight is higher, refer to the specific carrier’s rate sheet or online calculator to determine the shipping costs based on that weight. Consider any additional factors such as destination, service level, and any applicable surcharges.

7.Optimize Packaging:

If the dimensional weight is significantly higher than the actual weight, consider optimizing your packaging. Use smaller boxes or reduce excessive void fill materials to decrease the package’s dimensional weight. This can result in lower shipping costs for future shipments.

8.Consult with Shipping Carrier or Freight Forwarder:

If you have questions or need assistance calculating dimensional weight for international shipments, reach out to the shipping carrier or logistics.com”>freight forwarder handling your shipment. They can provide guidance and ensure accurate calculations specific to their policies and requirements.

Accurately calculating dimensional weight is crucial for estimating shipping costs for international shipments. By understanding and following the steps outlined in this guide, businesses can budget effectively, optimize packaging to minimize shipping expenses, and improve overall logistics planning when shipping goods from China. Consulting with shipping carriers and freight forwarders ensures compliance with specific dimensional weight calculations and provides additional support in navigating the complexities of international shipping.
