I am currently in the north east of the USA. I would like to ship good from Portland Maine or Boston or NYC if possible.
Well - You can more likely get someone from Portland to deliver them to the shipper from Florida. I have never shipped anything into Haiti so am just speculating. But that is the way I would try to plan it were I you.
My family always used Mayflower as the most reliable shipper but there are certainly others who are bonded, insured, honest and can make a secure delivery for you. I would expect their prices would all be similar. There is a huge shortage of truck drivers in the USA now so prices will probably be high.
When I moved from the US to the DR, I just sold everything and came with a backpack, a laptop and a guitar. I was 55. I know folks who shipped containers down for a cost of around $5k (??) was it?? but WAY back in 2001!! Perhaps other board members could tell you the prices to ship to the DR.
When I came back from the DR in 2016, bringing art, a few clothes and curtains packed in hand made trunks , some souvenirs and my precious handmade rocking chair. The shipper charged by the cubic foot. So I guess that is how they do it for anything less than a full container.
I don't know Okap at all - or what is available there.
But I do know that buying things like air conditioners and stoves and fridge.. all are easily available in the DR - plus they have imports from South America which are much smaller, and run by gas. Plus there is an Ikea in Sto. Dom and lots of very heavy mahogany furniture easily bought in Santo Domingo Este.
But - Then you would - have the challenge of getting a Dominican to transport them from Santo Domingo to Dajabon - which the folks here on DR1 could probably find for you... and getting someone in Okap to meet him at the border. The border at Ouanminte/Dajabon is a simple but dirt road crossing.
An Adventure for sure. I used to have a fantastic sense of adventure. But the DR/Haitian border is probably not such a fun place right now.
(after I have done all that, of course, I am exhausted! And when I was considering moving to Haiti FROM the DR, one of the Haitians that I was consulting said "DON"T bring anything from there. We have wonderful handmade furniture here." But - I would assume that it all in PauP which is very dangerous now.)
All to say that I am simply challenging you to reconsider the expense and burden of shipping goods? And to consider which ones. Who knows? You maybe a backpack, laptop, and guitar sorta guy.
My great-uncle, who was very, very wise - always advised my about travel :"Take half the clothes and twice the money."
That being said, my next door neighbors here near West Palm Beach are Haitian and every Christmas they LOAD their pick-up with all sorts of stuff destined for Haiti. So I will ask them how they do it. They would be shipping to PauP but perhaps the company ships to the Cap as well.
