This is completely down to the discretion of the officers. Each destination country charges customs and administrative fees on shipments containing dutiable items. Dutiable means that an item is subject to taxes. USPS does not have any way of knowing if an item is dutiable.
Post Office facilities must collect a Postal Service fee from the addressee for each item on which customs duty or Internal Revenue tax is collected. The Postal Service fee is authorized by international postal agreements to reimburse the Postal Service for costs it incurs clearing items through customs and collecting customs duties at the time of delivery
