I'm not sure how US Customs officially regard a wildlife product that is in private hands, in private utilitarian use, and will not be left in the USA. I do know from my native friends that they are hypervigilant about ceremonial eagle feathers, but it seems that is mostly because those have a high commercial value that affects an endangered species- seals are not that. I suppose it would be best to just leave the thing at home in Canada, but frankly that would not have previously occurred to me with mine. Dang it, do I now have to pay big bucks for a cheap sporran? (Actually there are no cheap sporrans, just inferior ones at slightly reduced prices.)

I'll probably be going down to the US this Easter and unless they're otherwise giving me a hard time at Customs, I'll ask about it. Of course one border agent's opinion is not binding on another, but perhaps there is a real policy. Where I cross, they're crazy on the topic of Granny Smith apples from AUS and NZ, and not in an approving way- other places they never ask.
