How to Configure ShipperHQ to Only Use Boxes in Packing Rules
Configure Dimensional Packing so ShipperHQ only uses boxes specified in your Packing Rules
Overview
By default, Packing Rules in ShipperHQ don’t limit items to only the boxes listed in a rule. Unless configured otherwise, ShipperHQ evaluates all available boxes and selects the best option using its Best Fit Algorithm — including boxes marked to “Be Used to Pack All Products.”
This article explains how to set up Dimensional Packing so that ShipperHQ only uses the boxes you’ve defined in your Packing Rules (Pack According to Box Rules).
Understanding Packing Rules
When you assign boxes to a Pack According to Box Rule, ShipperHQ treats those boxes as available when that rule applies. However, any box set to Be Used to Pack All Products is always available system-wide.
That means if you leave boxes marked as “Can Be Used to Pack All Products,” ShipperHQ may still include them even when a Packing Rule is assigned. To limit packing to only specific boxes, you’ll need to adjust both your box settings and Packing Rules.
Steps to Configure
Create a Default Packing Rule
-
In ShipperHQ, create a new Pack According to Box Rule.
-
Set this new rule as your Default Packing Rule.
This ensures any item not assigned to a specific rule will follow your default setup.
Update Box Settings
-
Edit each box currently set to Can Be Used to Pack All Products.
-
Deselect this option so these boxes are no longer globally available.
-
Save your changes.
This step prevents those boxes from being automatically considered for all shipments.

Assign Boxes to the Default Rule
-
Add your updated boxes to the newly created Default Packing Rule.
-
Save the rule.
Now, ShipperHQ will only consider the boxes tied to your Packing Rules when determining how items are packed.
Result
After completing these steps:
-
Items assigned to a specific Packing Rule will only use the boxes listed in that rule.
-
Items not assigned to a Packing Rule will use the boxes in your Default Packing Rule.
This configuration ensures ShipperHQ only considers the boxes explicitly tied to your Packing Rules, giving you complete control over which boxes are used during dimensional packing.
