This final rule amends the U.S. Customs and Border Protection (CBP) regulations to eliminate the requirement that a customs official at the port of export verify and sign CBP Form 3229, Certificate of Origin for U.S. Insular Possessions, and to require only that the importer present this form, upon CBP's request, rather than with each entry as is currently required. The importer is still required to maintain CBP Form 3229 in its possession or may be subject to the assessment of a recordkeeping penalty if it cannot be produced.
