Not an Amazon engineer (I work at AWS). But how would that be workable at Amazon's scale?

Who declares the country of origin? Who ensures compliance for item? How is compliance done? Do you review every single item?

How do you ensure that manufacturers update their country of origin declaration if/wehen they change downstream procurement? If you the raw materials are sourced in China and assembled in Vietnam, does that count as a Vietnamese product?

Amazon still has trouble with fake reviews, brushing scams, and straight-up counterfeits. Adding another system that needs to be policed doesn't seem like a very good idea. Especially when that system (country of origin flag on every product) has questionable upside.

Don't forget that for trade purposes (customs!) every item that is crossing borders already need to declare COO and that documentation and rules exist how to assign it based on value-added manufacturing steps.
