It’s safe especially if they come from within country, if your ordering from the uk or spain or wherever sometimes due to the packing they require inspections and if not done stealth can be confiscated though most ive ever seen come from it is just that a notice of confiscation for you americans.
Still i routinely send seeds south and none have been grabbed yet as far as im aware, though also due to how i ship.
Saying that welcome to the forums
