In counter-proliferation efforts, which situation does not require the commodity to depart the country?

In counter-proliferation efforts, the scenario involving a foreign national embassy does not require the commodity to depart the country because embassies operate as sovereign entities within the host nation. The goods and materials may be utilized, stored, or transferred within the embassy's jurisdiction without crossing international borders. This is significant as counter-proliferation measures often focus on the physical movement of items that may contribute to the development of weapons of mass destruction or other illicit activities. Since embassies are protected by diplomatic immunity, the transfer of commodities in this setting is managed differently than in typical commercial or inter-state transactions.

In contrast, scenarios like a transfer to a local business, inter-state transactions, or goods received from abroad all imply that the commodities involved would typically move out of the host nation’s control, either temporarily or permanently, thus elevating the need for scrutiny under counter-proliferation laws and regulations.
