from the Haitian side custom is a nightmare for forners,but if you know somebody from the inside things could get allot easier and less expensive.When forners get inside custom there is a big red light flashing "$$$$$$ is coming" and everybody want a piece of what you are bringing.
So i presume the DR is a little better but not by that much,so if you could send somebody local , it might be wiser to do so.
By the way, if somebody is stupid enough to bring illegal stuff to custom than he deserve what 's coming to him.
I know Oregon is well known for his "green tea" so i am not offended by their assumptions!
I know that some shipment company will bring your container to the port of entry and the client is responssible to deal with all the custom paper work .For whom is interested, a friend of mine is seving a 10 years in the haitian Jai for smoking 1/2 of a joint,that's after spending more than $15000.oo(they gave him a good deal, and the lawer is still asking for more money) it's a crasy place out there.So ,before venturing your self with something or some body,make sure you know or have an escape route(good lawer and plenty of money).
