The engineering drawing which may accompany a purchase order for custom-made product WOULD be included under "customer property" in terms of caring for it by protecting it from damage, alteration, or loss. I believe Jim is correct in that no specific type of customer property needs to be entered in your documentation, merely the inclusive term "customer property."
That said, I have seen some obsessive-compulsive types add a definition of customer property. Some definitions I have seen include clauses like the following (remember - MOST organizations do NOT do this):
- "any documents or physical items which the customer expects to be returned"
- "documents, samples, or tooling provided or paid for by the customer which the customer expects returned upon request."
My personal opinion is that such additional detail is not wrong, but certainly not required.
In my own experience, I held "gold samples" of customer-provided products for years until the product became obsolete after engineering revisions. When I offered to return the samples, I received written notice the customer considered them "scrap" to dispose of as I saw fit. In the case of engineering drawings which became obsolete, I had a clause I added in my acceptance of contracts which allowed us to scrap the drawings unless the customer specifically requested return of the obsolete copy when issuing the new revision. This was simply because I didn't want any obsolete documents around to prevent their accidental use.
