Can any regular / recent visitors flying intl into NKG advise if baggage is being xrayed prior to exit from baggage collection hall?

I know PEK and PVG mainly are now if arriving bw 8 or 9am and 8 or 9pm - but outside those hours customs are asleep.

I need take some faulty components back to NKG and would rather take in luggage rather than pay courier - but Chinese Customs have started taking dim view of such actions.

Any advice on recent experience very much appreciated.
