I agree about not being able to know the details as a customer, still not sure why they don't allow that.
> The fundamental problem is that the counterfeits-on-Amazon problem arose in the first place due to Amazon's method of not caring which individual item came from which vendor. Their system enabled them to not keep track of the provenance of an item. And this new system seems to require them to track genuine items. If they're going to do that, they can already do it entirely on their own end of things.
I'm not so sure about that. If there was a time they couldn't track, that's long gone. Amazon can definitely trace back what product from who was eventually delivered even if it was commingled.
They don't even store inventory together anymore, they'll have them store per-vendor.

I think the issue is that vendors are the ones that sell counterfeit, maybe willingly or sometimes unwillingly, their own supplier might be giving them counterfeit without them knowing.
Each vendor can opt-out of commingling, but then they have to print an Amazon barcode on their products to use FBA (fulfilled by Amazon).
For certain products, Amazon forces that anyways, like perishables and registered brands, unless you're approved by the brand. To be approved by the brand, you need to provide invoices from the brand to Amazon amongst other things.
If you don't want to put Amazon labels on each of your products, your options are to have Amazon track the existing manufacturer barcode, in which case commingling is also applied, but still Amazon can trace back your exact product based on the manufacturer barcode, they also won't physically mix your products with other products in the warehouse.
The other option is for you to ship it yourself and not use FBA, then you do what you want, you probably don't even need to have a barcode at all.
What Amazon then does is random product inspections and everytime someone returns an item with reason counterfeit or not as advertised, it gets inspected as well. And since they can trace it back to the exact vendor, they suspend that vendor if found selling counterfeit. Probably there's some level of like 3 strikes or appeals process, etc.
But that leaves open vendors selling counterfeit that fools the inspection or the customers. Or new vendors until they get inspected or have some customer return made. Since vendors are hard to trust, manufacturers can protect their authenticity of their products by signing up to transparency.
Anyways, that's what I gathered from reading their latest help and support, and from forums.
I'm still with you, as a buyer, I'd love to be able to see which vendor is selling commingled or not, which product have transparency or not, and even be able to filter for that in the search. I'd also love a country of origin for both product and vendor personally.
