In the latest edition of the Strategic Trade Research Journal includes a paper that addresses this issue, saying that export control requirements apply to WMD-related commodities even beyond first sale, but knowledge of these requirements is sometimes lost as commodities are sold and resold—and many “outdated” products can still contribute to a WMD development programme. The paper concerns a study to assess the secondary market and form recommendations to plug gaps in training and awareness, as well as control programmes. It is said that the secondary market for listed commodities may pose proliferation risks and export control challenges that may not be well understood, and that while measures may exist to mitigate the risks posed by the secondary market, those measures may not have been systematically integrated into export enforcement and outreach programs and secondary market resellers may not be aware of the requirements associated with exporting these commodities.
