Subject/verd disagreement: receive or receives

Which of the following questions are grammatically correct and why:

·         Does an item requires standard storage mechanism or special storage requirements, such as flammable cabinets, lubricants, and containers?

·         Does an item require a standard storage mechanism or special storage requirements, such as flammable cabinets, lubricants, and containers?

I feel that the first question is correct because of the subject/verb agreement rule. Item is singular (noun) and requires (verb) is singular. However, the client wants me to retain the second question.

Which of the above two questions are correct according to you and why?

The verb you are using is "does" and that matches the singular noun/verb rule.  The next verb should be "require".  I looked this up beacuse I wasn't sure how to describe the tense of "require" here; it is called base form.   

"After the helping verb "do", the next verb is the base form (just like a modal in the first rule).

Hi Shweta- your client is 100% correct: The second question ("Does an item require...") is, without a doubt, correct.

In this case, "does" is an irregular verb (3rd person singular). If you changed the question to a statement or responded to this question, it would be: "It does require..." You would not say: "It does requires..."
