CBP added new status that deactivates inactive importer accounts in ACE
CBP announced that on July 16, 2026 it would launch a new 'Inactive for Entry Purposes' status in ACE. The status automatically deactivates importer of record (IOR) accounts that have not filed an entry within 366 days, under 19 CFR 24.5(e). Deactivated IORs cannot transmit ACE Cargo Release or Entry Summary transactions, but the status does not affect other functions such as drawback, ISF filing, bonds, or acting as consignee.
Show Allied's positionHide Allied's position
This status took effect on July 16, 2026 and remains in place. Before we file a new entry for a client, we check whether their IOR account is active in ACE, since a lapse of 366 days without a filed entry can trigger deactivation for entry purposes. Clients who have not imported in over a year should tell us so we can confirm their IOR status before we submit entries on their behalf.
CBP posted an updated ACE deployment schedule in July 2026
CBP announced on July 10, 2026 that it had posted an updated Automated Commercial Environment (ACE) Development and Deployment Schedule on CBP.gov. CBP described the schedule as notional and subject to change. The notice pointed readers to CBP.gov/ACE for the latest deployment information.
Show Allied's positionHide Allied's position
This notice only pointed to a CBP schedule page and did not describe any specific system change. It did not affect how we file entries at the time and later CSMS messages would announce any actual ACE changes. Clients do not need to do anything about this notice.
CBP updated ACE AD/CVD case query to return unlimited manufacturer and exporter records
CBP announced an updated version of the ACE CATAIR AD/CVD Case Information Query (V11), posted on CBP.gov. The update let the query return an unlimited number of records for Manufacturer Names and Foreign Exporter Names, instead of a limited set. CBP deployed the change to the certification environment on June 4, 2026, and to production on July 9, 2026.
Show Allied's positionHide Allied's position
This is a technical update to a CBP data query system used for AD/CVD case lookups. It concerns how brokers and filers retrieve manufacturer and exporter data, not entry filing requirements, and clients do not need to act. We use the updated query results as part of our normal AD/CVD entry work.
CBP Held ACE Maintenance Window in July 2026
CBP announced ACE production standard invasive maintenance from 10:00 p.m. ET on Saturday, July 11, 2026, to 4:00 a.m. ET on Sunday, July 12, 2026. This affected system availability for ACE users during that window. This is a historical, dated notice and the maintenance period has already passed.
Show Allied's positionHide Allied's position
This was a routine, time-limited maintenance window that has already occurred and does not affect current filings. Clients did not need to take any action then or now. If clients experienced issues with entries filed around that window, they should contact Allied to review the specific entry.
CBP added a new CPSC data code to the ACE PGA message set
CBP announced an update to the ACE CATAIR PGA Message Set. The update added a new qualifier code, CP4, for component part descriptions under the PG19 record, created for Consumer Product Safety Commission eFiling. CBP noted other partner government agencies may use this code in the future.
Show Allied's positionHide Allied's position
This update concerns the technical data fields brokers use to file Partner Government Agency data in ACE, mainly for CPSC filings. It does not change any duty, classification or entry requirement for importers. Clients do not need to act, and we apply the correct data fields when we file entries that require CPSC information.
CBP Ran a Short ACE Maintenance Outage in July 2026
CBP announced a planned ACE system outage from 7:00 p.m. to about 9:00 p.m. Eastern time. The outage affected Multi-Modal Manifest, Air/Ocean/Rail EDI, Truck Manifest Mod, Mod ACE Portal Access, Cargo Release, and Entry Summary. CBP scheduled the work to address performance issues.
Show Allied's positionHide Allied's position
This was a one-time maintenance window that has already passed. It did not change any filing rules and does not affect entries we file now. Clients do not need to take any action regarding this notice.
ACE System Maintenance Completed in July 2026
CBP announced that an unplanned ACE system outage was resolved and normal processing resumed at 8:30 p.m. This was a system status update with no policy or filing changes. It affected anyone using ACE at the time, including brokers and filers.
Show Allied's positionHide Allied's position
This was a routine system restoration notice from July 2026 and did not change any filing requirements. It has no lasting effect on entries we file. Clients do not need to take any action regarding this notice.
CBP held an ACE test environment maintenance window on July 1, 2026
CBP announced a maintenance window for the ACE certification (test) environment on July 1, 2026, from 5:00 p.m. to 8:00 p.m. ET. The message did not describe any impact on the production ACE system used for filing entries. This was a routine, time limited maintenance notice.
Show Allied's positionHide Allied's position
This notice concerned a test environment, not the production system we use to file entries. It had no effect on entries we filed for clients and required no action from importers or shippers. Clients do not need to do anything about this notice now.
CBP added new ACE error to block conflicting duty status on auto parts and heavy vehicle HTS lines
CBP announced an update to the ACE CATAIR Error Dictionary that added a new fatal error, F876. The error stops an entry summary line from having both a dutiable Auto Part HTS number and a dutiable Medium and Heavy-Duty Vehicles HTS number in Chapter 99 at the same time. CBP deployed this validation to the certification and production ACE environments on June 25, 2026. The change affects filers who submit entry summaries with both types of HTS numbers on one line.
Show Allied's positionHide Allied's position
This was a system-level filing rule for entry summaries with combined Auto Part and MHDV Chapter 99 HTS numbers. It appears to remain in effect, since we have not seen a later CSMS message that changes it. If you import auto parts or medium and heavy-duty vehicles, ask us to review how your entries classify Chapter 99 duty status on these lines.
CBP held ACE maintenance window in late June 2026
CBP announced invasive maintenance on the ACE production system from 10:00 p.m. ET Saturday, June 27, 2026 to 4:00 a.m. ET Sunday, June 28, 2026. This was a scheduled system outage window affecting ACE availability. The message did not describe any lasting change to filing requirements.

This was a routine, time-limited maintenance window that has already passed. It required no action from clients then and has no bearing on entries filed today. Clients do not need to do anything in response to this notice.
CBP explained how importers reactivate a deactivated Importer of Record number
CBP announced it was deactivating Importer of Record (IOR) numbers in ACE that had not been used to file entry for a year or more and had no outstanding post-entry transactions. CBP described how to reactivate a deactivated IOR through an ABI broker Transaction Processing message or, if that fails, by emailing a revised CBP Form 5106 to a Center Entry Specialist Team. This affects importers whose IOR number CBP had deactivated for inactivity.
Show Allied's positionHide Allied's position
This concerns how importers restore a deactivated IOR number so entries can be filed under it again. Nothing since this message has changed the process as CBP described it. If a client's IOR number is inactive in ACE, we can submit the required Transaction Processing message or Form 5106 on their behalf, but the client should first ask us to check the current status in ACE.
CBP added automation for ACE Portal account reactivation and applications
CBP announced new tools for the ACE Secure Data Portal. Automation now reactivates Trade Account Owner (TAO) accounts when the request comes from an email tied to that TAO account, and helps users locate their company's TAO. CBP also introduced new web forms for applying for or updating ACE Portal accounts, including importer accounts and sub-accounts.
Show Allied's positionHide Allied's position
This message concerns how importers and other ACE Portal account holders manage their own accounts, not the entries we file. Clients who manage their own ACE Portal accounts can use these tools directly with CBP. We do not need any action from clients on this notice, but they can contact us if they want help identifying the right ACE Portal process for their account.
CBP held a webinar in June 2026 on setting up ACE Portal accounts
CBP's Office of Trade announced a free webinar for June 17, 2026 on how to set up and manage an ACE Portal account, covering new webforms and Trade Account Owner functionality. The webinar targeted trade users needing help with ACE Portal setup and addressed common questions. CBP said recordings of past webinars remain available for replay on its website.
Show Allied's positionHide Allied's position
This was a routine CBP outreach webinar about ACE Portal account setup and is not a policy or filing change. It does not affect the entries we file for clients. Clients do not need to act, though anyone who missed it can check CBP's website for a recorded replay.

CBP added new ACE error code requiring USDA license for sugar and dairy HTS entries
CBP announced an update to the ACE CATAIR Error Dictionary that created a new fatal error, F60D, for agriculture related HTS numbers. The error required a USDA agricultural license type 14 number in the 52 record for entries using listed re export sugar program and dairy rate quota HTS numbers, regardless of entry type. CBP said any entry using these HTS numbers without the license number would be rejected. The change was scheduled to deploy to the CERT and PROD environments on May 30, 2026.
Show Allied's positionHide Allied's position
This validation still applies to entries we file that use the listed sugar or dairy HTS numbers. We enter the USDA agricultural license type 14 number in the 52 record on those entries to avoid rejection. Clients importing goods classified under these HTS numbers should confirm they hold a valid license and send us the license number before we file the entry.
CBP held ACE maintenance window on May 30 to May 31, 2026

CBP renamed ACE error code 613 from HTS relationship/sequence mismatch to HTS relationship mismatch
CBP announced an update to the ACE CATAIR Error Dictionary (V47) that changed the name of error code 613 from HTS RELATIONSHIP/SEQUENCE MISMATCH to HTS RELATIONSHIP MISMATCH. CBP removed the sequence reference because incorrect HTS number sequencing now triggers a separate existing error, 852 HTS OUT OF SEQUENCE. The update deployed to the CERT and PROD environments on May 28, 2026.
Show Allied's positionHide Allied's position
This is a technical labeling change to how ABI systems report certain HTS errors, and it concerns filers like Allied rather than importers directly. We account for the updated error names and the separate 852 sequence error in the entries we file. Clients do not need to take any action on this change.
ACE Had a Brief Scheduled Outage in May 2026
CBP announced that the ACE EDI System would be down for a 30 minute window on May 26, 2026 to address performance issues. The outage affected all modes of manifest processing, including truck, in-bond, and entry summary filings. The notice was limited to that specific maintenance window.

This was a short, one time maintenance window for ACE that has already passed. It does not affect any entries we file today. Clients do not need to take any action regarding this notice.
CBP held ACE test environment maintenance window on May 20, 2026
CBP announced a standard invasive maintenance window for the ACE certification (CERT) environment on May 20, 2026, from 5:00 p.m. to 8:00 p.m. ET. This affected the test system used for ACE certification, not the production filing system. The notice did not describe any impact beyond that window.

This notice concerned a scheduled maintenance window in CBP's test environment, not the live production system Allied uses to file entries. It did not affect entries we filed for clients. Clients did not need to take any action.
CBP Updated ACE AD/CVD Case Query to Return Unlimited Manufacturer and Exporter Records
CBP announced an updated ACE CATAIR AD/CVD Case Information Query (V11) that let the Manufacturer Details and Foreign Exporter Details outputs return an unlimited number of records instead of a limited set. CBP said the update would deploy to the CERT environment on May 28, 2026 and to PRODUCTION on July 9, 2026. The message directed technical questions to CBP client representatives and other questions to the Entry Summary Accounts and Revenue Division.
Show Allied's positionHide Allied's position
This was a technical change to the ACE system query brokers use to look up AD/CVD case data, not a change to duty rates or entry requirements. Both deployment dates have already passed, so the update has been in production since July 9, 2026. Clients do not need to act on this notice; if a client has questions about AD/CVD case data on a specific entry, we can review it for them.
CBP added new ABI error code for HTS not allowed for importer of record
CBP announced an update to the ACE CATAIR Error Dictionary adding error code F865, which flags a tariff number as not eligible for the submitted importer of record. CBP scheduled the update for the CERT test environment on May 19, 2026, and for production on June 2, 2026. The message directed technical questions to CBP client representatives and the Entry Summary Accounts and Revenue Division.
Show Allied's positionHide Allied's position
This is a technical filing system update that concerns brokers and how CBP's ABI system validates entry data. The error code is now live in production, so we may see it returned if a filed tariff number is not eligible for the importer of record on an entry. Clients do not need to act, but if we receive this error on a filing we may ask for corrected classification or importer information.

CBP Detailed ACE Reports for Tracking IEEPA CAPE Refund Claims
CBP announced that after the April 20, 2026 CAPE tool launch in the ACE Portal, importers could use several ACE Reports products to monitor IEEPA refund claims. These included ES-022, REV-603, REV-613 and REV-615, which track refund status, ACH issuance, diverted funds and rejected ACH refunds. CBP said Treasury would begin issuing IEEPA refund ACH payments as early as May 12, 2026.
Show Allied's positionHide Allied's position
This message explained tools for tracking IEEPA refund claims filed through CAPE, which CBP still uses for IEEPA refunds. We can run these ACE Reports to check the status of refund claims tied to entries we filed and to confirm whether Treasury issued, diverted or rejected a refund. Clients do not need to take action from this message alone, but should tell us if they have not received an expected refund so we can review the report data with them.
