So now reality has unfolded a bit more and this is what has happened so far…
Long reasoning omitted, $1,200 was the declared value on the package.
The package was then held in the carrier’s warehouse in this major European country for a week. Why? Because Custom’s required a ‘Proof of Delivery’ to the USA form. The Seller provided this.
Customs is now charging an Import Tax. Yes, even though the paperwork, including two sets of original shipping documents, clearly shows the LP went from A to B and now back to A. The rate to the Seller will be between 7% and 19% so between $84 and $228.
Thank you for all your thoughts and I will keep you posted!
