(April 2) Computer problems have delayed regulations requiring truck drivers to provide information to the U.S. Customs and Border Protection when entering the U.S.

Known as the Automated Commercial Environment (ACE), the program’s phase-in dates for its electronic manifest program in Arizona, Washington and North Dakota have been set back.

The system requires carriers to file information related to the content of trucks as well as data on tractors, trailers and drivers. It took effect in those three states Jan. 25, but there has been a 60-day grace period.

The second phase of the program, which would include denying entry to carriers not attempting to file an e-manifest, was scheduled to begin as early as March 26. However, the CBP said in a memo that computer problems have prevented carriers from knowing if their manifest was received, delaying that step for at least 30 days. The third phase, to encompass the rejection of trucks without e-manifests and to involve fines for noncompliance, has been delayed from April 26 to at least May 26.

The CBP said in its memo that no enforcement action, other than a warning, would be taken until the problems are solved.

ACE was designed to allow officers to focus their attention on suspicious cargo while allowing legitimate shipments to move across the border faster. Lee Frankel, president of the Fresh Produce Association of the Americas, Nogales, Ariz., said it has instead slowed traffic at the border.

“It’s a disincentive to even try to use the system,” he said.
