In Step 3: Prep & Boxem, Amazon will determine the pack groups for our products, and we'll assign them to boxes accordingly.

The left side of the page shows a list of the pack groups and SKUs in each group. As you create boxes and assign SKUs to them, they will be displayed on the right.

Pack Groups

When determining pack groups, Amazon identifies similar products in size, weight, shape, and how they need to be packed. This helps make sure everything gets packaged and shipped efficiently and safely.

Depending on the types of products in your shipment, they may be split into different pack groups. Each group will have an identifying color.

Note: SKUs from different pack groups cannot be packed together.

In the Pack Groups section, you'll see each SKU's image, title, ASIN, SKU, Condition, and quantity.

Next to each product are buttons to Assign, Bulk Assign, and Print FNSKU labels.

Prep instructions will display based on the prep category chosen when adding the products to the shipment. If you (the Seller) are the prep owner, you are responsible for following the instructions to prep the product before placing it into a box. Additional guidance on prep can be found here: Prep guidance

The number of units that need to be assigned will show and update as you add them to boxes.

Creating Boxes

To create your first box, click Create first box on the right side of the page to get started.

If you need additional boxes, enter the number of boxes and click the Create new box(es) button.

You can also create new boxes while assigning products, or create boxes in bulk by using the Bulk Assign or Dimensions & Weight buttons.

Assigning Products to Boxes

To assign a product to boxes individually, click Assign next to the product.

From here, you have the option to assign them manually or split them evenly between boxes.

The Bulk Assign function allows you to assign the product to boxes as you create them and enter their dimensions and weight, making it an excellent option for case-packed products.

Viewing/Editing Boxes

On the right side of the screen, you can view the contents of each box and make any needed changes.

The name, dimensions, and list of products assigned to each box will be displayed.

The box color reflects the pack group based on which products are assigned to them.

If dimensions and weight need to be entered for an individual box, click Set Dimensions and weight to enter them.

If you still need to enter dimensions and weight for multiple boxes, you can do this in bulk by clicking Dimensions & Weight at the top of the page.

Clicking the three vertical ellipses next to a box name will open a menu with the following options:

• Update Dimensions & Weight
• Delete Box

Note: Deleting boxes may cause your box names to be out of order. This can lead to issues when applying box labels, so we recommend changing your box assignments over deleting boxes when possible.

To remove a product from a box, locate the SKU in the Pack Group section on the left and click the "x" in the box assignment tag.

‍
After you've assigned all of the SKUs in each pack group to a box and entered the dimensions and weights for the boxes, click Continue to send Amazon the shipment details. Boxem will request the placement options and associated transportation fees for the shipment(s).

You'll see a message letting you know that box assignments cannot be changed once you move to the next step. If you're happy with your boxes, click Submit Pack Groups to move forward to Step 3: Confirm Shipments.

If you decide you do not want to proceed with shipping the products, click Cancel Shipment. From there, you can create a new shipment and relist the products when you're ready.
