Sorry if this is too off topic, but wasn't able to find meaningful advice after hours on Google.
I shipped a few jackets for alterations to the maker in Italy. These were purchased in the US during one of the tailor's trips. I had declared a value of $6,000 USD with the note that the jackets were being sent back to the country of origin for repair. Customs is assessing duties and taxes of 1,790 Euros. Do I have any options to dispute this assessment?
