Reverting back to old and previously approved material - PPAP Re-submission?

Hi,

For 1 product type we have a couple of PPAP approvals for the past decade, which starts from the initial submission and followed by a couple few more due to the revision of the material source/supplier.

We have totally switched to the new material supplier and had the PPAP approved already.
My question is that if ever we have decided to use or revert back to the previous/old material, do we need to re-qualify our products and submit another set of PPAP docs?

Thanks in advance

Re: Reverting back to old and previously approved material--PPAP Re-submission?

As I recall the PPAP manual lists change of Material / material source as one of the reasons for a resubmission of the PPAP. Reverting to a previous supplier or source would require that you Re-PPAP with that source. If this should ever happen to be necessary I would contact the Customer to determine the extent of any performance related testing they might want to see. :2cents:

Thanks...
So I would need to treat it as a new supplier again.
Things change over time. Your "old" supplier may have changed (hopefully improved?) their manufacturing processes and even their suppliers. PPAP documents must always reflect the current "state of affairs."

You neednot submit a new ppap when you go back to old supplier.If your customer wants to see ppap during audit of your plant,show him old ppap.If the gap is too long your customer can demand new ppap.The requirement is: each source should have a ppap or one ppap can include reports pertaining to various sources.

I disagree. When you change a supplier, PPAP is required. Period.

I disagree. Notification to the customer is required, and the PPAP is required unless otherwise specified by the customer. See the table on page 13 of the 4th Edition PPAP manual. Note that the notification must precede the change, and the change must be approved by the customer.

I am very familiar with PPAP requirements.

I agree, notification may be all that is required, but it sure is handy to do a Level 1 Warrant Only (supported by the old data - depending on how old it is) as a clear documentation of when the change was made, and that the customer really did agree with the change. Of course, the customer does not have to take the time to process a warrant if they didn't ask for it. But, at least you tried (due diligence).
