Section 113.4 - Bonds and carnets(a)Bonds. All bonds required to be given under the customs laws or CBP regulations will be known as CBP bonds.(b)Carnets. A carnet is an international customs document which serves simultaneously as a customs entry document and as a customs bond. Therefore, carnets, provided for in part 114 of this chapter, are ordinarily acceptable without posting further security under the customs laws or CBP regulations requiring bonds.T.D. 84-213, 49 FR 41171, Oct. 19, 1984, as amended by CBP Dec. 15-15, 80 FR 70163 , Nov. 13, 2015
