ShipStation supports using UPS Ground Freight Pricing for your shipments once UPS has enabled it on your UPS account. ShipStation cannot support this feature with your UPS account unless it is enabled by UPS directly first. You can learn more about UPS Ground Freight Pricing by visiting their site here.
If you already have your UPS account added to ShipStation, and UPS has enabled ground freight pricing, follow these steps to enable this feature in your ShipStation account:
Head to your Account Settings (the wrench icon in the upper right).
Next, select Shipping and then Carriers & Fulfillment from the sidebar on the left.
Click Edit next to your UPS account.
Check the box next to Enable Ground Freight Pricing and then click Confirm.
To use ground freight pricing on your orders, go to the Orders page.
Open the Order Details for an order you wish to use UPS Ground Freight Pricing by clicking the Order Number. Please note that you MUST have a UPS service selected in order to view the following UPS Ground Freight Pricing options on your order.
In the Other Shipping Options section, check the box next to This shipment requires a Freight Classification code, and enter the Freight Classification Code.
Once selected, the UPS Ground Freight Pricing will be used when the label is created.
