Re: Approved supplier list
Hi,
You may have a criteria defined in your supplier selection procedure indicating that you have various levels of vendors in your QMS, for example Type A, B, C, and D depending on their potential impact to your product. Then you can define which type of control you consider appropriate for them. For example a Type A vendor may need annual audits, COA's, maintan a current ISO certification, and IQC on each batch because it is a critical supplier. On the other extreme, a vendor type C (a less critical one) would only need to provide you with a survey suited to meet the particular needs of your QMS or bussiness needs.
I would take as valid that a vendor type D (for toiletries or office supplies for example) does not need to be listed in the ASL based on your analysis because it does not have an impact at all.
At the end, you should maintain your controls over the suppliers in accordance to the stated requirements in your procedure....and please don't forget to define a criteria for removing vendor from the ASL.
I hope this helps! This is my particular interpretation but other folks out there could provide you with their own approach.
