According to the US Postal Service there are things that are necessary when shipping an item to Germany that is to be declared as a gift.
A parcel may be addressed to a street address or to a post office box. A local telephone number for the addressee should be provided when the item is addressed to a street address and must be provided when the item is addressed to a post office box.
For Priority Mail International parcels, an invoice, in duplicate, is required for all commercial shipments regardless of value and all personal shipments valued at $300 or more. The invoices must be affixed to the outside of the parcel or may be enclosed in PS Form 2976-E with the customs declaration.
Mailpieces delivered through international bulk mail services must be addressed with the correct postcode number or delivery zone number, if one exists. Without this number, the German postal administration will return such pieces to the sender or the country of origin due to insufficient addressing.
Import licenses or certificates are required for meat and meat products; pasta products; dairy products; egg and egg products; plant and plant products; tobacco products; and cigarette paper. Senders should ascertain before mailing whether the necessary documents are held by the addressee.
The customs treatment of gift parcels will be facilitated if the customs declaration is marked by the sender
Private Geschenksendung (personal gift package).
Customs authorities require invoices with books valued at 26 euros or more (currently $35.20).
