Is XLX1 a pallet-delivery only fulfillment center?

Hi everyone,

My product meets all the requirements for SPD delivery and the total units I am planning to ship are under 200 units, which also meets SPD requirements. The fulfilment center designated for my shipment is XLX1.

Here is the question. A little bird told my colleague that XLX1 is a pallet-delivery-only fulfilment center, though I don't see any information in Seller University about pallet-delivery-only fulfilment centers. I assume that the fulfilment centers starting with XLX are for oversized and extra large items, but are they pallet-delivery-only fulfilment centers?

We are now stuck on which shipping method we should choose. Does anyone have information about this? Any insight is highly appreciated.
