When a package is imported from the USA to your country, your government may decide that you need to pay duties and taxes. In most countries, imports need to be declared, i.e. a description, quantity and value of the imported goods have to be provided to local customs authorities so that duties and taxes can be assessed. Import duty is a tax that the importer has to pay to bring foreign goods into his or her country.
These charges are controlled by your government, Ellusionist has no LEGAL way to prevent these charges from being incurred.
