If anything good came from nuclear bomb testing, this would be it. Levels of C14 have been dropping steadily since that time, creating a pattern known as the "bomb-curve".
Major moving companies will manifest cargo but if you are doing the move yourself you could be asked for the documents and could face confiscation if you do not have it.
Simple ivory test : Heat a needle with a flame from a candle, lighter, stick the heated end into the key, if it melts it's plastic or ivorytine ( simulated ivory plastic) if it doesn't go in it's ivory. Most pianos made up until 1956 ( Pre- Ban) CITES Treaty states 1947, if the key covers have not been replaced might have ivory left on them.
You dont want to use water, bleach, any sprays, nothing that will get in the keyways and lock up the key.
