(a) Whether any undertaking, document, or set of documents constitutes or would constitute an international agreement within the meaning of the Act or of 1 U.S.C. 112a shall be determined by the Legal Adviser of the Department of State, a Deputy Legal Adviser, or in most cases the Assistant Legal Adviser for Treaty Affairs. Such determinations shall be made either on a case-by-case basis, or on periodic consultation, as appropriate.

(b) Agencies whose responsibilities include the negotiation and conclusion of international agreements are responsible for transmitting to the Assistant Legal Adviser for Treaty Affairs, for decision pursuant to paragraph (a) of this section, the texts of any document or set of documents that might constitute an international agreement. The transmittal shall be made prior to or simultaneously with the request for consultations with the Secretary of State required by subsection (c) of the Act and §181.4 of this part.

(c) Agencies whose responsibilities include the negotiation and conclusion of large numbers of agency-level and implementing arrangements at overseas posts, only a small number of which might constitute international agreements within the meaning of the Act and of 1 U.S.C. 112a, are required to transmit prior to their entry into force only the texts of the more important of such arrangements for decision pursuant to paragraph (a) of this section. The texts of all arrangements that might constitute international agreements shall, however, be transmitted to the Office of the Assistant Legal Adviser for Treaty Affairs as soon as possible, and in no event to arrive at that office later than 20 days after their signing, for decision pursuant to paragraph (a) of this section.

(d) Agencies to which paragraphs (b) and (c) of this section apply shall consult periodically with the Assistant Legal Adviser for Treaty Affairs in order to determine which categories of arrangements for which they are responsible are likely to be international agreements within the meaning of the Act and of 1 U.S.C. 112a.
