Some clients have a requirement to use a volumetric weight for calculating the shipping price, or to use the greater of volumetric and standard weight. This extension supports this capability.

• You can determine if the attribute “volume_weight” exists after you install the extension. Add this as required to your attribute sets. If you’re unsure how, take a look at the attribute configuration guide from the left menu of this wiki.
• Before you can use the “Volume Weight” attribute you need to add it to your attribute sets. “volume_weight“.
• In the product listing you will then see the “Volume Weight” attribute is present. You need to set this as required.

To compare the total volume weight with standard weight and use the greater of the two, set “Use Higher of Volume/Weight” to Yes in the shipping method configuration. Set up your weight/volume based rules as normal in your CSV file, as demonstrated in the example below.

If you would rather use both volume and weight as factors of the shipping price you need to set “Use Higher of Volume/Weight” to no and use a CSV file like the one below. The volume from and volume to replace the item from and item to columns.
