Thanks to all above. To clarify; I need to know the price BEFORE I ship a container load. So, second question is...is the determination of aduana set by a contractual form/agreement?
And that is why you should try to contact the agency in the link I posted above in post#7.
Finding the proper category is the hardest part. There are literally hundreds of pages of tariffs listed in the DR/CAFTA agreement and its appendixes. You need to know what category your product falls under and into and what, if any, sub-class it falls under/into, whether there is a quota on that product, and finally, what the tariff rate, flat/fixed or floating, will be on each item.
Then you can verify that information with Aduana, prior to importing into the DR.
Tip: If you are serious about importation, contact Aduana last. Tell them your product, what tariff schedule/regimen you expect it to fall under and cite the section of DR/CAFTA. When Aduana feels they are dealing with someone who knows the rules (they like to test rookies), they are less inclined to try re-categorize your product into a higher tariff regimen.
It is not a simple process, But, once you establish your tariff(s) on the first container, it becomes a mere formality for the containers of equal goods that follow.
Again, good luck.
Respectfully,
