(a) Subject to the conditions of paragraphs (b), (c), and (d) of this section, the following transactions are authorized:
(1) All transactions and activities otherwise prohibited by this part that are for the conduct of the official business of the United States Government or the United Nations by contractors or grantees thereof; and
(2) All transactions and activities otherwise prohibited by this part that are for the conduct of the official business of the United Nations specialized agencies, programmes, and funds by employees, contractors, or grantees thereof.
(b) Contractors or grantees conducting transactions authorized pursuant to paragraph (a) of this section must provide a copy of their contract or grant with the United States Government or the United Nations, or its specialized agencies, programmes, and funds, to any U.S. person before the U.S. person engages in or facilitates any transaction or activity prohibited by this part. If the contract or grant contains any sensitive or proprietary information, such information may be redacted or removed from the copy given to the U.S. person, provided that the information is not necessary to demonstrate that the transaction is authorized pursuant to paragraph (a) of this section.
(c) Any U.S. person engaging in or facilitating transactions authorized pursuant to this section shall keep a full and accurate record of each such transaction, including a copy of the contract or grant, and such record shall be available for examination for at least five (5) years after the date of the transaction.
(d) No payment pursuant to this section may involve a debit to an account blocked pursuant to this part.
This license does not relieve any persons participating in transactions authorized hereunder from compliance with any other U.S. legal requirements applicable to the transactions authorized pursuant to paragraph (a) of this section. See, e.g., the Export Administration Regulations (15 CFR parts 730 et seq.).
Paragraph (e) of § 538.212 exempts transactions for the conduct of the official business of the Federal Government or the United Nations by employees thereof from the prohibitions contained in this part.
