SPD (small parcel delivery) means shipping individual boxes, each with its own label, through a parcel carrier. LTL (less than truckload) means shipping boxes stacked on pallets by freight. For wholesale, SPD suits smaller shipments; LTL usually costs less per box once you are shipping many cases.
Quick answer: A handful of boxes → SPD. Many cases, heavy products or a full pallet’s worth → LTL. Compare both quotes in Send to Amazon, since the cheaper option depends on box count, weight and destination.

Amazon Partnered Carrier for Wholesale Shipments
Amazon’s partnered carrier program lets you buy shipping through Seller Central at negotiated rates, for both small parcel and LTL. The cost is charged to your seller account, and tracking flows into your shipment automatically. Compare the partnered rate with your own carrier for each shipment.
Shipping From Your Supplier
The simplest option is a supplier that ships prepped cases straight to your FBA shipment. Compare that with a prep center in prep center vs supplier prep.
