How to Define Box Sizes


This is a guide on how to set up and define boxes and pallets in ShipperHQ. First, you must make sure that you have Dimensional Shipping enabled. With Dimensional Shipping enabled, ShipperHQ will take the order and pack the items volumetrically into boxes defined, giving your customers the most accurate shipping rates. The steps below will teach you how to define a box and any settings associated with that box.

Setup: Define Box

Once Dimensional Shipping is enabled, you’ll see ‘Box Definitions’ in the bottom left corner. This is where can define your boxes either individually or via CSV table import. To create a box individually, you will go to Box Definitions along the left column and click on “Add New +”.

Basic Panel

  • This is where you will name the Box. That information will be passed back as the Box Identifier so make sure to name it accordingly.
  • This is where the length, width, and height of the box is defined.
  • If you are using USPS Flat Rate Boxes, there are four USPS Flat Rates pre-set for you to choose and Save. ‘Custom’ is used for any non-preset boxes where you will set dimensions yourself.
  • You can also set a max quantity as well as a max weight for the box. These options are used if only a certain max weight or quantity can be packed into the box e.g. only 5 items can be packed into a box, the box can only hold up to 10lbs.

Optional Panel

  • This is where you can assign the box to only be packed for specific carriers, if applicable. If you want the box to be allowed for all Carriers, then leave this blank.
  • The “Assign this Box to all Products” option. ShipperHQ can potentially pack any item into this box if this option is enabled. If that is not the case, leave this unchecked so it can be used in a Dimensional Rule.
    • NB: When “Assign this box to all products” is selected, the box will not be displayed in the Magento possible shipping boxes attribute as the box will be treated as being assigned to all products. Deselecting the option will display that box in the possible shipping boxes attribute as normal.

Advanced Panel

  • This is where you can set a Packing Weight to account for packing materials such as extra cardboard, dry ice, or bubble wrap.
  • You can also set a Per Box Surcharge. This would be to cover the cost if the box is more expensive for certain products.
  • You can also set a Freight Class for this specific box, if applicable.
  • Additionally, if you are setting up a Master Box (also known as a ‘Case Pack’), this is where you will indicate that. More info on Master Packing Boxes below.

Master Packing Boxes

There is an option to assign a box as a Master Pre-Packed Box. This is also known as a Case Pack.

A master packing box is generally a prepacked box that is shipped alone. For example you may sell shampoo in boxes of 6, 15, 30. If someone buys 8 of the item then it would pack in a 6 master box then the 2 would go in a combined box with other items.

Further details for how Master Packing Boxes can be used are in this article.

Entering Boxes via CSV

To enter via CSV Import, you should first do a CSV Export to get a blank CSV file. You will then enter the information for each individual box per line, with the same information from above. You can find an example Box CSV below.
