Good morning.
I will follow you on IMDS which your customer requested.
According to Ito san, he needs to know customer name and ID to provide IMDS.
IMDS is different from other documents like MSDS, because IMDS is not a kind of "document".
Firstly, Ito san will put IMDS data into the system via internet. And after that, the customer will check it via internet as well. So, to put data into the system, Ito san need both of customer name and ID.
Please inform Ito him of both information once you get.
I hope this email helps. Thank you.
