On May 16, 2016, U.S. CBP published a Federal Register Notice, 81 FR 30320, to announce that certain electronic entry and entry summary filings accompanied by FDA data can only be processed through ACE.

US Customs and Border Protection (CBP) announced a new timeline for the transition to ACE on the May 13th ACE Technical call. CBP will release a CSMS message and update their website with the new mandatory use dates in the near future.

The newest ACE timeline is as follows.

The May 28th deadline for the transition to ACE is just 29 business days away.

Filers will be required to file in ACE, not ACS, for the transactions listed below. The required filing of these entry types does include those with APHIS Lacey Act and NHTSA data (unless paired with other PGA data).

FDA filings will still be allowed in ACS. More information to come.
