GAO Report – DOD Supply Chain: Suspect Counterfeit Electronic Parts Can Be Found on Internet Purchasing Platforms

Suspect counterfeit and bogus—part numbers that are not associated with any authentic parts—military-grade electronic parts can be found on Internet purchasing platforms, as none of the 16 parts vendors provided to GAO were legitimate. “Suspect counterfeit,” which applies to the first two categories of parts that were tested, is the strongest term used by an independent testing lab, signifying a potential violation of intellectual property rights, copyrights, or trademark laws, or misrepresentation to defraud or deceive.

After submitting requests for quotes on both platforms, GAO received responses from 396 vendors, of which 334 were located in China; 25 in the United States; and 37 in other countries, including the United Kingdom and Japan. Of the 16 parts purchased, vendors usually responded within a day. GAO selected the first of any vendor among those offering the lowest prices that provided enough information to purchase a given part, generally within 2 weeks. Under GAO’s selection methodology, all 16 parts were provided by vendors in China.

Specifically, all 12 of the parts received after GAO requested rare part numbers or postproduction date codes were suspect counterfeit, according to the testing lab. Multiple authentication tests, ranging from inspection with electron microscopes to X-ray analysis, revealed that the parts had been re-marked to display the part numbers and manufacturer logos of authentic parts. Other features were found to be deficient from military standards, such as the metallic composition of certain pieces. For the parts requested using postproduction date codes, the vendors also altered date markings to represent the parts as newer than when they were last manufactured, as verified by the parts’ makers. Finally, after submitting requests for bogus parts using invalid part numbers, GAO purchased four parts from four vendors, which shows their willingness to supply parts that do not technically exist.
