Offers in compromise submitted pursuant to the provisions of section 617 of the Tariff Act of 1930, as amended (19 U.S.C. 1617) must expressly state that they are being submitted in accordance with the provisions of that section. The amount of the offer must be deposited with Customs in accordance with the provisions of § 161.5 of this chapter.

An offer in compromise will be considered accepted only when the offeror is so notified in writing. As a condition to accepting an offer in compromise, the offeror may be required to enter into any collateral agreement or to post any security which is deemed necessary for the protection of the interest of the United States.
