Wait - Honeywell certified their stuff was in compliance, yet it wasn’t... that is pretty unscrupulous, considering they know where all their parts come from.
Not necessarily. Certs often get emailed at the time of shipment. Sometimes they get a lot of scrutiny before the parts leave incoming inspection, sometimes this stuff doesn't get caught unless there is some suspicion and the paper trail gets audited.
Best thing to do is to come-clean.
