'Request' vs. 'Inquiry'

[Lee12jan]

Hi,

Sometimes I get confused with 'request' & 'inquiry'.
For below example of one email, I am not sure the use of 'request' & 'inquiry' is correct.
1) Please help modify the Subject & Content in natual eng writing.
====================================================
Subject: IBM has a/an request/inquiry for ARM7

Content: Dear Steven:

I just called IBM, they requested the price of ARM7
and 5pcs sample. Please help deal with their inquiry, thanks.

====================================================

2) Could I also simplify subject as 'ARM7 request (IBM)'

Very thanks in advance.

Hi,

'Inquiry' suggests investigation, looking for additional information. You make an inquiry about someone or something. The classic expression used to describe what the police are doing when they have detained Mr X is to say: Mr X is helping the police with their inquiries. 'Request' suggests asking for something. You could phone a firm requesting further information on a particular product.
