I talked with customs in Kingston and it still the same as it ever was. "Used" household goods can be imported duty free but the customs people will decide what condition things look to be in before it will be called "used"
Anything new will have duty on it. Sometimes they will value the items by your receipt and sometimes it will be given an arbitrary value.
There is also a flat fee for the container itself. I ship in barrels and its 5,500 as of my last.
