Iceland is in the European Economic Area and in the Schengen area, but it is not in the European Union customs union. Goods crossing the Icelandic border cross a real customs frontier in both directions, with a declaration, a classification and a value. The Schengen part is about people; the customs part is about goods, and conflating the two is the most common mistake made here.
On an island the practical consequence is sharper than on the mainland. There is no road alternative and there are only so many departures, so a consignment held for a documentation question is not held for an hour, it is held until the next suitable flight. That is why the declaration is prepared before the courier leaves rather than at the counter.
Fisheries and anything of animal origin sit under a veterinary and health certification regime that is strict and enforced in both directions. It is the single most common regulated category on this desk and it is raised at the first conversation.
The ordinary requirements apply as everywhere: a description that supports the classification, a defensible value, a consignee who can receive, and temporary admission for equipment that is coming back out again.
