Tiger in a suitcase

There might be treaties where the signatories agree to pass their own criminal laws.

i think paedophilia is one such crime where that happens.

There's no such treaty I can find, not even between the EU states.

The United Nations Convention on the Rights of the Child (CRC) is an international treaty that legally obliges states to protect children's rights. Articles 34 and 35 of the CRC require states to protect children from all forms of sexual exploitation and sexual abuse. This includes outlawing the coercion of a child to perform sexual activity, the prostitution of children, and the exploitation of children in creating pornography. States are also required to prevent the abduction, sale, or trafficking of children.[161] As of November 2008, 193 countries are bound by the CRC,[162] including every member of the United Nations except the United States and Somalia.[163][164]

the above aside. i think a workable treaty on such things as animal transportation under such circumstance where exotic animals and wildlife are being illegally taken for the wild or other places should have some kind of universal deterrent
