I just experienced this same charge. I made a payment on Alibaba using Paypal and was charged a SPREAD_DEBIT charge. Paypal did not know what this was. I contacted Alibaba and it is a 2.99% processing fee for using Paypal. However, it is strange how Paypal breaks it out by making the itemized charges less and adding them into this SPREAD_DEBIT line item. It doesn't make sense to me how it appears on my Paypal invoice, but if you take your total order amount in Alibaba and apply a 2.99% processing fee the total amount paid through Paypal should equal that. I hope this helps.
