请问允许从美国邮寄DVD光盘到国内吗?

我从网上订购了10盒DVD光盘,对方说美国邮局不一定允许邮寄,并给出一个邮局的规定,
"Manuscripts, printed matter, photographic negatives, gramophone records, films, magnetic tapes, video tapes, etc., which could do political, economical, cultural, or moral harm to the People's Republic of China."
我想问一下究竟可不可以寄?在中国海关会不会被退回?如果可以寄,会不会需要交税?谢谢...
