Does nonconforming product disposition include parts bought from the supplier?

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?

Rework itself doesn't require customer concurrence unless it is required by customer. For us, if a die-casting part is outside specificaton, we need to scrap it.

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

Rework itself doesn't require customer concurrence unless it is required by customer. For us, if a die-casting part is outside specificaton, we need to scrap it.

Admittedly, I don't have a copy of the IATF 16949:2016 document, so I have to go by what others have mentioned. In this post, Peters mentioned that paragraph 8.7.1.1 states the following:

The organization shall obtain customer authorization prior to further processing for “use as is” and rework disposition of nonconforming product.

This presentation material confirms that.

So, what gives?

In typical IATF fashion, the requirements are all over the place. 8.7.1.1 -- Customer Authorization for Concession (where you think you would find it) -- requires "customer authorization prior to further processing for 'use as is' and rework dispositions of non-conforming material." It is silent on repairs.

But never fail, look at 8.7.1.5 -- Control of Repaired product. It requires "documented customer authorization" for the repair.

Fun times. I'd rather look at the Eclipse without glasses than read this stupid standard. It's less painful on they eyes.

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.

I made the same case in the sister thread, but was told otherwise.

Here's the clause text:

The organization shall obtain a customer concession or deviation permit prior to further processing whenever the product or manufacturing process is different from that which is currently approved.

The organization shall obtain customer authorization prior to further processing for "use as is" and rework dispositions of nonconforming product. If sub-components are reused in the manufacturing process, that sub-component reuse shall be clearly communicated to the customer in the concession or deviation permit.

The organization shall maintain a record of the expiration date or quantity authorized under concession. The organization shall also ensure compliance with the original or superseding specifications and requirements when the authorization expires. Material shipped under concession shall be properly identified on each shipping container (this applies equally to purchased product). The organization shall approve any requests from suppliers before submission to the customer.

I think that sentence confirms that when you disposition nonconforming products as RTV (Return to Vendor) and they intend to rework the parts, you must approve the rework first and, THEN, request approval from your customer. This should make third-world countries bureaucracy seem the pinnacle of efficiency.
