Can pallets be stacked?

Yes, pallets can be stacked. They must be engineered to double-stack in-bound to Costco whenever it optimizes freight efficiencies. The pallet load weight must not exceed 2500 lbs and the height must not exceed 58", including 5.5" for pallet height. For bagged products weighing over 10 lbs, specific options for unitizing are provided, such as using stretch film or corrugated shroud.

Can purchase orders be mixed within a single carton?

It is not explicitly mentioned whether different purchase orders (POs) can be mixed within a single carton. However, for pallets, each e-commerce shipment carton and pallet must contain one SKU, and mixed pallets must be properly labeled. This implies that mixing POs may not be preferred or allowed in individual cartons.

Can SKUs be mixed on a single pallet?

Yes, SKUs can be mixed on a single pallet, but they must be clearly labeled as mixed. The SKUs should be separated from each other on the pallet and not intermixed. The pallet must have a label that notes item numbers and quantities included. Pallets must be fully cubed and wrapped with corner boards.

Can SKUs be mixed within a single carton?

SKUs cannot be mixed within a single carton. Ecom goods must be packed one size/color per carton, and the carton should contain only one ecom item number. Mixed colors and sizes will lead to the depot refusing the PO. For pallets with mixed SKUs, a label notating the item numbers and quantities included on each pallet must be provided.

Imported items require specific shipping mark labels, while domestic shipments have no specific labeling requirement for GS1-128 or any other logistics labels on master cartons from Costco North America. However, if suppliers choose to use GS1-128 labels, they should follow the GS1 global standard: place labels on two adjacent sides of the load, outside of any pallet or stretch wrap.
