What is the INCORTERMS that drives the faithful seller customs and pick it up the delivery location?

Sorry for delay in response

Better to buy FOB customs cleared at seller's side when the shipment is made on vessel.

Or to buy FOT (free on truck) when your are loading on trucks-trailers-lorries 

If you means customs clearance at destination , better to specify incoterms C&F customs cleared

i didn't understood your question but would like say that the inco terms does not drives the faithfulness of customer. INCO terms are medium to facilitates to Logistics operation  ( movement of manpower or equipment from one to another)
