Phytosanitary certificates

[Fritz77]

Hey Tomatovillians,

as I’m preparing next season’s growlist, I am wondering if I could have some problems by ordering seeds from the US or Canada. I did find some websites that ship to Europe but I also read the following on seedsavers.org:
“ Buyers will pay the actual costs of phytosanitary certificates, if required for delivery. The standard rate for an official phytosanitary certificate from the United States Department of Agriculture is $85.00 USD. Some shipments may require two certificates, if the shipment contains both seeds grown in the United States and seeds grown abroad. If this is the case, then the fees will be $170.00 USD.”
Now, considering that I have a small garden and that my nest order will likely be woth $ 20-25, I would like to avoid such a cost.
How do I know in advance if such certificates are required? Has anyone ever ordered or shipped seeds from/to Italy? Do you know if there are additional costs, besides the shipping ones described in each site, for a small international order (6-7 packs)?
Thank you
