ACE Reports Modernized: What Changes for Brokers and Importers

Key Points

• ACE Reports Modernized is a new interface for the existing ACE Reports data, not a new data source, not a new family of reports, and not a change to what CBP collects.
• The same entry summary, cargo, in-bond and account reports you run today, including ES-001 and ES-002, are the reports you run on the modernized tool once your account is migrated.
• Saved custom reports, filters and scheduled runs built in the legacy tool may not carry over, so plan to rebuild and revalidate them rather than assuming they migrate.
• CBP announces migration waves, report availability and the legacy tool's retirement through CSMS and the ACE Reports page on cbp.gov; confirm current dates there, as of October 2026 no date should be assumed from memory.
• The links in this article go to the primary documents: CBP's own ACE and CSMS pages, the tariff schedule and the regulations themselves. Read the source.

ACE Reports Modernized is the rebuilt ACE Reports platform that U.S. Customs and Border Protection is rolling out to replace the legacy reporting tool inside the ACE Secure Data Portal, presenting the same trade data through a new interface. Importers, customs brokers, trade compliance managers and anyone else with ACE Reports permissions use it to run entry summary, cargo, in-bond and account reports against their own data. It sits after filing in the entry lifecycle: it is the self-audit, reconciliation support and management reporting layer, not a filing channel.

Why CBP is rebuilding ACE Reports and what stays the same

ACE Reports Modernized exists because the reporting layer of ACE was built on older technology than the rest of the portal, and CBP is moving the same reporting capability onto a current platform. The important point for compliance teams is the negative one: ACE Reports Modernized does not change the underlying records. The entry summary, cargo, in-bond and account data in the modernized tool is drawn from the same CBP systems of record that fed the legacy tool, so a correctly filtered report should return the same rows in either place.

What does change is everything around the data. Navigation, the report catalog layout, filter construction, date range handling, column selection, sorting, scheduling and export formats are all presented differently. ACE Reports Modernized therefore costs your team relearning time rather than remapping time: the fields mean what they always meant, and the published ACE Reports data dictionary, CBP's reference defining each data object available in ACE Reports, its source record and its meaning, remains the authority for what a field contains.

Who is affected and when migration happens

Every ACE account with reporting permissions is in scope for ACE Reports Modernized, but accounts do not all move at once. CBP migrates accounts in waves and announces those waves, along with which reports are available in the modernized tool at each stage, through the Cargo Systems Messaging Service and the ACE Reports page on cbp.gov. Do not plan around a rollout date or a legacy retirement date you heard secondhand; check CSMS and the CBP ACE pages for the current schedule, and recheck before any quarter close or audit deadline that depends on reporting.

Account administration during migration is the Trade Account Owner's job. If the owner has designated a proxy TAO, the ACE Trade Account Owner proxy role, meaning a user the Trade Account Owner authorizes to manage the account's users and permissions on the owner's behalf, that proxy is usually the person who confirms which staff still hold reporting permissions after the account moves. A migration is a good moment to review that list, because stale accounts and departed employees show up clearly when permissions are re-examined.

How to prepare an account for ACE Reports Modernized

Preparing for ACE Reports Modernized is mostly an inventory exercise. List every saved custom report and scheduled run your team depends on, and for each one record the report family it is built from, the filters applied, the date logic, the columns selected and who receives the output. That inventory is what lets you rebuild quickly in the modernized tool and prove the rebuilt version matches.

Validate rebuilt reports against legacy output

While both tools are available to your account, run the same report in each with identical filters and compare row counts and totals. Differences almost always come from a filter that was set differently, a date field that means something other than what you assumed, or a default the new interface applies that the old one did not. Resolve the difference before you retire the legacy version, not after.

Start with the reports that carry the most risk

Rebuild the reports that feed duty payment, drawback, reconciliation and AD/CVD monitoring first. For most filers that means the entry summary families: ES-001, the ACE Reports ES-001 Entry Summary Header Details report with one row per entry summary, and ES-002, the ACE Reports ES-002 Entry Summary Line Details report with one row per line item.

Common ACE Reports Modernized mistakes

The failure modes around ACE Reports Modernized are predictable, and all three are avoidable with planning.

The first is assuming saved legacy reports carry over. Teams discover at month end that a scheduled report simply stopped arriving, and the person who built it years ago has left. The second is comparing outputs across the two tools without matching the filters, then raising a false alarm about missing entries or duty variances that are really a date-range or status-filter mismatch. The third is missing the legacy tool's retirement date and losing access to a report your close process depends on, with no rebuilt replacement ready.

A fourth, quieter problem is single-person dependency. If one analyst knows how every saved report is built, ACE Reports Modernized turns that into an outage risk. Document the filter logic in writing while the legacy version still runs.

How ACE Reports Modernized relates to other ACE functions

ACE Reports Modernized is a reporting window onto data created elsewhere in ACE, so its outputs are the evidence base for several other workflows. Entry summary reports support ACE Reconciliation, the ACE program under which an importer flags an entry summary for later reconciliation of undeterminable value, classification, 9802 or FTA issues and then files a reconciliation entry that closes them. They also support the ACE protest module, the portal function through which importers, brokers and attorneys file, amend and track protests, the electronic CBP Form 19, under 19 U.S.C. 1514 and 19 CFR part 174, and against which CBP records its decisions.

Reports are also how filers check their own keying against ACE AD/CVD case management, the ACE function with its public ADCVD Search through which CBP publishes Commerce's case numbers, company suffixes, cash deposit rates, effective dates and liquidation instructions. Classification review runs the same way, with report output checked against the Harmonized Tariff Schedule.

Two related channels are outside ACE Reports Modernized entirely. DIS, the Document Image System, is CBP's ACE channel for transmitting electronic images and structured documents such as invoices, certificates, permits and mill test certificates tied to an entry, in-bond or PGA line; reports may tell you a document was expected, but DIS is where it moves. ACE truck eManifest, the electronic truck manifest highway carriers must transmit to CBP before arrival at a U.S. land border port carrying conveyance, crew, equipment and shipment data that PAPS, BRASS, FAST and in-bond releases key off, likewise feeds data that cargo reports can surface but is filed through its own channel.

Finally, ACE Reports Modernized continues the role that ITRAC once played. Importer Trade Activity (ITRAC) data is the importer-specific entry data extract an importer requests from CBP under the Freedom of Information Act for its own transactions, and historically it was how importers audited their brokers' filings before ACE Reports made the same self-audit possible on demand.

Frequently asked questions

Does ACE Reports Modernized contain new data?

No. ACE Reports Modernized presents the same trade data as the legacy ACE Reports tool through a new interface. It is not a new data source and not a new report family, so a report with matching filters should return matching rows in either tool.

Will my saved reports and schedules move to ACE Reports Modernized?

Do not assume they will. Plan to rebuild saved custom reports and scheduled runs in ACE Reports Modernized, and document each one's filters and date logic while the legacy version is still available so the rebuild can be validated.

When is my account migrated to ACE Reports Modernized?

CBP migrates accounts in waves and announces the schedule, including the legacy tool's retirement, through CSMS and the ACE Reports page on cbp.gov. Confirm the current dates there rather than relying on a date circulated internally.

Do I need new ACE permissions to use ACE Reports Modernized?

Reporting access is still controlled by your ACE account's permission structure, managed by the Trade Account Owner or a designated proxy TAO. Review the user list at migration and confirm with CBP if a user who had reporting access in the legacy tool cannot see reports in ACE Reports Modernized.

What importers and brokers should do

• Inventory every saved custom report and scheduled run now, recording report family, filters, date logic, columns and recipients, and store that inventory outside one analyst's head.
• Subscribe to CSMS and check the ACE Reports page on cbp.gov for your migration wave, report availability and the legacy retirement date; recheck before any audit or close deadline.
• While both tools are live, run the highest-risk reports in parallel with identical filters and reconcile row counts and duty totals before retiring the legacy version.
• Have the Trade Account Owner or proxy TAO review reporting permissions at migration and remove users who no longer need access.
