You didn’t say what country you are sending the instrument to, or for what reason. Most countries make the assumption that you are sending the instrument there to sell it, and they want to make sure they will get their money(import duty, VAT tax, et.). So they will charge you accordingly up front. Telling them it’s only temporary or you’re planning to take it back out of the country means nothing to them. You will have to pay all fees as if you are selling the instrument there. So you need to research this carefully BEFORE sending the instrument off. You may have to buy a bond, which is basically a contract with a bond company that tells the country in Europe that all fees will be paid by the bond company if you don’t take the instrument back out of the country. At the very least you will probably have to pay about 25% of the value of the instrument for the import duty and VAT tax that will be due immediately.
