Conditionally accepted goods are items accepted for shipment only when the sender presents complete invoices, documents proving origin, or specialized permits.
Common categories include: functional foods, cosmetics, pharmaceuticals, medical devices, and products of animal or plant origin.
High-value goods should have their value declared to serve as the basis for compensation in case of loss or damage.
The post office has the right to require the package to be opened for inspection before accepting this category of goods.
