Set the right inspection plan – it might involve a check of the main components and/or the first finished products and/or a final random inspection. Don’t say “we will send a third-party QC company”, as this might actually freak some suppliers out. Instead, say “we are working with an inspection agent to confirm the quality of the goods before shipment”.
