How to Split the Cart Based on Box Weight

Overview

You can configure ShipperHQ to automatically split shipments when the total cart weight exceeds a box’s maximum capacity.

For example, if a box can hold a maximum of 35 lbs, and a customer’s cart totals 50 lbs, ShipperHQ will automatically pack the order into multiple boxes.

This setup helps ensure accurate rates and efficient packing across all products on your site.

Solution 1: Apply a Weight Limit to All Products

If you want to apply a weight limit globally:

1. Go to your FedEx carrier settings in ShipperHQ.
2. Locate Maximum Package Weight (default is 150 lbs).
3. Change it to your desired limit, such as 35 lbs.

This will cause ShipperHQ to split the shipment into multiple boxes whenever the total exceeds that limit.

If you need more detailed control over packing or want to define unique limits per box, use Solution 2 below.

Solution 2: Set Maximum Weight per Box

1. Make sure Dimensional Packing is enabled under Advanced Features in ShipperHQ.
2. Go to Boxes and click Add New Box.
3. In the Optional tab, set the Maximum Weight value (for example, 35 lbs).
4. Save your changes.
5. Test your setup in Test Your Rates to confirm the box splits correctly when the weight limit is exceeded.

Result

When the total cart weight exceeds the defined box limit, ShipperHQ automatically splits the shipment into multiple boxes to ensure proper rate calculation and efficient packaging.
