Frozen, chilled and fresh semen, and flushed embryos, from verified European stations. Every listing carries the donor's own pedigree, the collection centre's EU approval number where one exists, and the health tests the station has actually recorded β blanks stay blank rather than being filled in for you.
Every destination has its own import regime, and the permit almost always has to exist before collection. These are the authorities that issue it β the station handles the paperwork with you, and HorseStox does not certify on their behalf.
