Say you have some products that must ship freight no matter what. Even if they’re in the cart with other items. This is supported with Shipping Groups in ShipperHQ.
- Create your Shipping Group (i.e. FREIGHT_ONLY)
- Click on the the Advanced panel
- Check the box for Must Ship Freight
Assign Products to their Shipping Groups
Be sure to assign your relevant products to the new group before you test. Whenever this shipping group is in the cart, freight rates will be calculated for the whole order.
