This final rule implements the provisions of section 203 of the Security and Accountability for Every Port Act of 2006. On November 25, 2008, Customs and Border Protection (CBP) published an interim final rule (CBP Dec. 08–46) in the Federal Register (73 FR 71730), that finalized most of the provisions proposed in the Notice of Proposed Rulemaking. It requires carrier and importers to provide to CBP, via a CBP approved electronic data interchange system, certain advance information pertaining to cargo brought into the United States by vessel to enable CBP to identify high-risk shipments to prevent smuggling and ensure cargo safety and security. The interim final rule did not finalize six data elements that were identified as areas of potential concern for industry during the rulemaking process and, for which, CBP provided some type of flexibility for compliance with those data elements. CBP solicited public comment on these six data elements and also invited comments on the revised Regulatory Assessment and Final Regulatory Flexibility Analysis. (See 73 FR 71782-85 for regulatory text and 73 CFR 71733-34 for general discussion.) The remaining requirements of the rule were adopted as final.
