clause 7.2.1 actually is very interesting because depending on the type of activities you perform, and the type of product/service you provide it can be part of many different processes, examples include:
1. Analysis of tender requirements
2. Presentation of product information
3. Site Surveying
the outputs of the process meeting this requirement is usually the input to another "Review" process aimed at identifying if the organization has the ability to meet such requirements or not.
I have met with situations where the customer requirement is provided verbally, and not as a purchase order or request for quotation, or contract or any other document for that matter, however, most of those situations have a myriad of problems related to communication, and so, in such cases like for instance call centers, or fast food home delivery services, voice recording can be used or simply have your sales people record the requirements in an order themselves then have the customer sign it or stamp it. That is not the focus of this requirement though, 7.2.1 is asking you to consider all requirements related to the product including but not limited to:
1. Legal obligations arising from meeting the customer request like for instance all the paper work and release forms needed for export and import
2. requirements not stated by the customer directly but inferred, such as packaging
3. safety requirements for handling your products ...etc.
And so, if a customer goes to an exporting company and asks them to export goods which are normally banned in his country, they should take note of such legal issues as being part of the deal and not just the pricing, and quantity needed.
