Products packed in cases have the same SKUs, but individual products have separate SKUs
The "packing type" of your shipment—individual or case-packed—will be requested by Amazon Seller Central. If the SKUs or conditions of the items in a box differ, select Individual products.
If the items in a box have the same SKUs and terms and will be sold separately, choose case-packed products.
Multi-packs are sold as sets, whereas the products in a case pack are sold separately. Case packs are not the same as multi-packs.
