According to Noonsite on Curacao's custom:
Duty paid on equipment
will be refunded on departure. Spares may be imported free of duty, but this must be arranged with customs
at the airport
and it is usually easier if the services of a local agent are employed.
Hope this helps, by the way, which part of NB were you?
We are in Bathurst and leaving nest fall and may end up in Curacao for the hurricane
season. Who knows our path may cross.
