Yes all boxes that arrive in the Dominican Republic will be opened and inspected by Customs.  It is strongly recommended not to ship fragile items such as glass, collectibles, or valuable items as items may damage when customs put items back in the boxes.  Make sure to declare all items that you want to ship to avoid any penalties.  Shipping any prohibited items is an offense and may lead to fines and or jail time.  You may call us before shipping items to get more information of items that may concern you when shipping.
