【求助】GMP现场检查英文表达

现场检查 : on-site assessment

“市场销售注册”这种提法不太对，应该是“注册、上市销售”。其实注册就是申请market authorization的过程，拿到market authorization以后才可在欧盟市场上销售。邮件可以这样写：
Dear **,
We plan to market ** (药品名称) in EU region. Please kindly inform whether an on-site inspection shall be conducted and provide some hints on how to prepare for it. Your early reply will be highly appreciated.

Best regards
** (落款）

关于欧盟GMP的现场核查，你可以看看EMEA的网站，上面有很详细的解释：
