Import duties are happening

Today I received a package from the Netherlands which was drop shipped to me. Custom duties needed to be paid. The UPS driver gave me the choice of writing a check made out to UPS or going on-line and paying which would have lead to the delivery happening tomorrow. Well since I am going to be gone for a few days wrote the check. I had no clue custom duties were in play and after calling the distributor… he was shocked at the notice of a custom duty. And immediately offered to reimburse. So no issue there. Now getting documentation from UPS required jumping through hoops and barking like a dog. 
Caveat Emptor going forward.
