The best you can ask for is a robust quality control system.
The chinese have taken great pleasure in buying brands and replacing top quality products with cheap and nasty replacements (obviously maintaining the quality product pricing). Or they lower the price to put pressure on competitors.....with the intention of driving them out of business.
After a few of years the public work it out......sometimes....
Just because these part have a "number" it doesn't mean jack .....
If airliner parts can be faked, a few nut plates are nothing....

Boeing has stated that mechanical parts, electronic parts and materials have been counterfeited. Physical parts include bolts, nuts, and rivets. Electronic parts include resistors, capacitors, and integrated circuits. Materials include composite chemicals, steel, and titanium.[8] In 1996 unapproved parts were found to originate from sources such as counterfeiters, thieves, "strip and dip" operations which hide defects with metal plating, and from production overruns.[7]
