GM's GP-12 Early Production Containment applicable to Tier 2 Suppliers?


Jim Green

Just out of curiousity, has anyone that is a tier 2 supplier been required to do a GM-12 Early Production Containment???

We're a tier 2 supplier and I have never heard of that GM requirement! What is it and why would tier 2's be involved?

Jim Green

Roger I'm glad you responded to this cause you are the King of Interpretation.
Here is the scoop.
Are customer, who is a large steel company, said that GM is requesting PPAP's from them. They in turn want a ppap from us.
One of the main criteria included in this PPAP is a GP-12 (lcocated in the PPAP book in the Customer specific section II on page 34. The GP-12 is titled Early Production Containment.
I was confused because we have done PPAP's for other tier 1 customers doing business with GM and they have never requested it. Any help is appriciated.

If G.M. requires PPAP from Tier I and also says that Tier I will require PPAP from Tier II then GP-12 would be a requirement to be held at Tier one per record retention requirements and the tier I would do the same, depending on the submission level (1-5).

GP-12 is really very easy and we all probably do it on all new products anyways, so it is probably just the case of using the GP-12 procedure and related forms.:bigwave:


Looking at the PPAP Manual in the Customer specifics, GM is looking for the GP-12 requirement to be covered in your Control Plan.
I'm intrepreting that in your "Pre-Launch" control plan, you need to state that GP-12 will be followed. We have EPC (Early Production Containment) here, but I can't remember the exact number of parts that must go through EPC before GP-12 is satisfied.....I think it's something like two weeks of full production at launch will be 100% checked with no defects found before EPC can be stopped. (I'm sure if I'm wrong I will be corrected in no time :) )
I'm going to try to find the GP-12 procedure that I know is around here somewhere....that might help clarify this also.

All that said, it's still interesting that we've never had to comply with GP-12, being a tier 2 supplier. I guess there's a requirement written somewhere that states that some tier 2's have to do this and other tier 2's don't have to!

GP-12 for sub-suppliers

We usr the GP-12 containment methodology frequently, for our suppliers. We re-word the letter a little , but the intent is the same.

Bill Ryan - 2007

We are (recently) Tier 1 to GM. We were Tier 1 in the past when Delphi was still "under the umbrella". We're very used to having to perform to "GP-12" requirements.

We have been Tier 2 and Tier 3 for many years, with most of our Tier 1 customers supplying GM, and have always had the "GP-12" requirement. It is not that big a deal when it is planned for and has proven to "verify" the Production Control Plan.

I believe (without looking it up) the default number of pieces is 1200, unless otherwise specified. It has only been recently that we have had customers "specify" a quantity and then it is mostly a length of time or number of shipments, as opposed to a specific quantity of parts.
