How to Set a Fixed Rate for a Shipping Group


You want to set a fixed rate for one or more shipping options or methods when a certain shipping group is in the cart.

In this article, we’ll use the example of setting a fixed rate on UPS Ground if the order has products in the “Perishable” shipping group.


Ensure you have your UPS Carrier set with UPS Ground as an available shipping method.


  1. Create a Shipping Group. For this setup example, we’ll call it PERISHABLE. Don’t set any advanced settings on the group.
  2. In the lefthand Navigation, go to Carrier Rules > add a new Rule.
  3. In the Basic panel of the rule, name it. For example, we’ll name ours “$5.99 on UPS ground for Perishable items”.
  4. Under the Shipping Methods, Add the Shipping Methods you want to override with flat rate. For our example, we’ll select UPS Ground.
  5. In the Conditions panel, select your shipping group under Includes One or More of These Shipping Groups. Ours would be PERISHABLE.
  6. In the Actions panel, set the Action to Perform dropdown to “Set/Surcharge Shipping Methods”. Set Adapt Shipping Rates dropdown to “Set Rates”, and Apply Shipping Rate/Percentage to “Per Shipping group”. A new dropdown will appear called Apply to Shipping Group(s). Select your group from above. From our example, we’d select PERISHABLE.
  7. In the Set/Modify Shipping Rate section of the Actions panel, enter the $ amount to set as the rate. For our example, we’d set 5.99
  8. Save your rule.

After you save this rule, and once there is a product assigned to the shipping group, the products will always override their live UPS cost to $5.99 per the assigned shipping method(s) in the rule.

Note: Please keep in mind that you have the option of setting the rate by each item in the shipping group, the entire cart, origin  or per each box the PERISHABLE items have packed into from the drop-down of Apply Shipping Rate/Percentage drop down.
