I work in manufacturing in the US. Incoming quality control, for Chinese vendors, is
necessarily set up with zero-trust. This isn't a "trust but verify" sort of thing, it's strictly "do not trust". Assume that, at every step of the chain, there will be a lie: change of process, material change, collected data, and that the product being given to you is even yours (delivering a knockoff at the final step, and reselling yours on the gray market).
This is all common knowledge, proven by example after example that it's necessary to have zero trust. It's truly an adversarial system. All the extra engineering effort for IQC is still cheaper. And, there's rarely an alternative to the amazing manufacturing ecosystem that is China.
After tracking down several of these types of issues, it appears that the Chabuduo mindset [1] is a very real thing.
