French to English Other Manufacturing Office supplies

This term features in a list of quality criteria for office supplies to be supplied by the successful tenderer of an invitation to tender. It seems to be referring to a product characteristic. At first, I thought perhaps that the word “service” might have been omitted, which would give “quality of service provided”, but that didn’t really make sense in the context, as that part of the list seems to be referring to product characteristics – in the end, I decided that it might actually be literally “rendering quality”, but I'm not sure what that has to do with “office supplies”, which I presume are just staples, pens and paper, etc.! It could be that I need to go back to my client for more info, but if anyone could help now, that'd be fantastic! Many thanks!
