Should I hire a third-party quality inspector, or can I trust the factory's own QC?

The short answer

Trust the factory's QC for reorders from a supplier with a long clean track record; hire an independent inspector for every first order and anything above a few lakhs in value, because the factory's own team is incentivised to pass the batch, not fail it. An inspection fee that catches a bad batch before it ships is cheaper than eating the cost of returns, a bad review, or a full re-manufacture.
