CITES
The Washington Convention on International Trade in Endangered Species Appendix 2
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), known in German as the Washington Species Protection Convention (WA), has existed since 1973. It was discontinued because of the dramatic decline many species closed by poaching and trade.
In the meantime, 183 contracting parties worldwide have joined this convention. That is almost 95 percent of all countries in the world.
CITES grants different levels of protection to more than 37,000 animal and plant species, regardless of whether they are traded as live specimens, parts thereof or products made from them.
One of these is the green tree python (Morelia viridis).
Most of the wild species covered by the Convention are not yet critically endangered but are potentially threatened by trade (Appendix II).
Here, the agreement allows sustainable trade, which must be documented.
An export license for specimens of these animals and plants may only be granted by the exporting state if the removal of the specimens in question does not harm the conservation of the species.
The Federal Agency for Nature Conservation is responsible for Germany.

For green tree pythons bred in human care, the cared for animals within the European Union (EU) must be reported to the lower nature conservation authority.
Furthermore, the transfer is only permitted with a proof of origin, which in Germany contains different information depending on the federal state.
Of course, every sale or death of an animal must be reported.
To check the details and circumstances of the care, an on-site inspection can be carried out by an official veterinarian.
If animals are to be traded outside the EU, a CITES must be applied for (e.g., this applies to Switzerland).
This is applied for with a certificate from the Lower Nature Conservation Authority, which documents that the animal is registered and owned by the keeper.
As of January 1st, 2023, these documents cost around EUR 70.00.
The preparation of both documents should take 3 - 4 weeks.
As far as I know, direct shipping to countries that do not belong to the EU is not possible.
It is forbidden to declare a shipment with snakes as insects (such shipments are often disguised as cockroaches).
This practice is often suggested, since a parcel with live insects can be handed in at a parcel shop on the German border, a show with snakes, however, is not.
