Does nonconforming product disposition include parts bought from the supplier?

It states 8.7.1.7 that for product not meeting requirements , the organization shall verify that the product to be scrapped is rendered unusable prior to disposal.

My understanding is that it also includes the parts we bought from our supplier. In my situation, we buy die casting and stamping parts from our supplier, if any problems found in our production, we put the parts in the red box and send the parts back to the supplier monthly, in most circumstances, they rework the parts and re-send them to us.

So, the quesiton is if we make the parts unusable, like cutting, the supplier may not accept it becuase sometimes the parts are expensive.

So, how to deal with these parts?

thanks in advance for your reply

If the parts are dispositioned for rework, they are not being scrapped, obviously.
However, apparently, the IATF 16949 standard requires you to obtain customer concurrence with the rework disposition BEFORE it happens. :mad:

Fully vaccinated are you?

You are not scrapping the parts nor are YOU reworking them.

I'm not sure if you need customer concurrence, though, since technically your supplier is doing the rework. The question becomes how far down the chain is customer concurrence for rework required?

If you're under IATF/TS, anything not in accordance with current PPAP approval will need customer approval. IATF 8.7.1.1 and 8.7.1.4 lays it out pretty specifically. They are getting pretty stingy on this these days.

I don't have a copy of the standard (thank goodness).
Does it require prior approval for rework as well as repair?

if so, since rework is usually just redoing an approved process what is the rationale for prior approval?

Rationale? :lol:

It is even worse, Bev. Now that the scope of the IATF:16949 audits are mandated to include ALL automotive products, EVEN the ones that are destined to non subscribing customers such as Honda, Toyota, etc, the supplier will have to request an approval for reworking products from these clients as well. Which, CERTAINLY will create non value added FRICTION between the supplier and such customers. I can see a Toyota SQE thinking: Why is this supplier bugging me to approve a rework? Can I trust them? Are they competent?

Look at the discussion on this thread.

We run into this problem daily. We stamp and form a "round" cup. But after we punch all sorts of holes and such in the side, the dia. may get a bit wacky depending on the material, spring back, stress, etc. In some instances we may need to re-strike the part to bring it back in spec. We had a customer balk, because it wasn't part of the original process. They wanted to PPAP the re-work. If everyone wanted that, we would never get anything accomplished.

According to the IATF16949, for rework, you only need to asses the risk before rework. For repair, you have to get customer approval.

For the rework, IATF16949 doesn't require you to submit to customer for approval.

For rework
" If required by customer, the organization shall obtain approval from the customer prior to commencing rework of the product"

For reparir
"The organization shall obtain a documented customer authorization for concession for the product to be repaired"

I think it is quite logical, because after rework, the part conforms to specification, so you don't have to submit it to customer for approval if there is no requirement from the customer. For repair, even if you the part is repaired, it is still outside specification but can be used.
