Short version: the CBP ACE Portal is the free government system of record for every U.S. import entry. It is authoritative, universal, and legally load-bearing. CBP describes the portal as a way to run reports and "monitor their CBP data" — not as an interpretation or alerting product.EntryProof is not trying to replace ACE — it reads the same entry data ACE holds and interprets it back to the importer in the form of "these 3 shipments are missing a linked CPSC certificate."
We quote CBP rather than paraphrase it. On cbp.gov/trade/automated/getting-started (checked September 14, 2026), CBP writes: "The ACE Secure Data Portal is a free, web-based access point designed to connect CBP, trade partners and Partner Government Agencies," which "gives users access to more than 400 reports that can be used to evaluate compliance and monitor daily operations." CBP also states that the portal "is primarily a resource through which users can monitor their CBP data" and that "filings such as manifests (other than truck import) entries and entry summaries cannot be made via the ACE portal" — those move through Electronic Data Interchange, which CBP describes as linking "to all CBP systems, including the Automated Commercial Environment (ACE)."
CBP's own description of the portal is reporting and monitoring. It does not describe an alert-when-this-HTS-code-gets-added-to-a-PGA-list feature, a plain-language weekly digest of an importer's certificate coverage, or an interpretation layer that turns report exports into "these 3 entries failed to link a valid CPC." That is a statement about what CBP publishes about its own product, not a characterisation of how well it works; we have removed the unsourced third-party quality claims that previously appeared in this section.
CBS News covered the launch of CBP's CAPE tariff-refund platform, which went live on Monday, April 20, 2026, in "Tariff refund portal off to bumpy start as some businesses report glitches" by Megan Cerullo (updated April 21, 2026). In that article, Beth Benike, co-founder of Busy Baby, described spending more than four hours on hold and encountering a "Duplicate tax ID" error, and Rick Woldenberg of Learning Resources described receiving the message "The system is currently experiencing high volume, please try again later." CBP told CBS News it was looking into reports of problems. Those are two named importers' reported experiences of one platform launch, as published by CBS News on that date — not a general finding about CBP, ACE, or CPSC eFiling, and we do not present them as one. The practical takeaway for an importer is narrower: a government filing system is not a monitored SaaS product with a commercial support SLA, so the readiness work belongs upstream of it.
| Capability | CBP ACE Portal | EntryProof |
|---|---|---|
| Price | Free | Free readiness check + paid tiers |
| Role | Government system of record for U.S. imports/exports | Independent readiness and interpretation layer |
| Data authority | Ground truth — the actual entries CBP holds | Reads ACE-side data and CPSC-side certificate data together |
| Interpretation | Reports and data monitoring (CBP's own description) | Plain-language weekly digest |
| Alerts | Not a published portal feature (CF-28 / CF-29 arrive after the fact) | Proactive alerts before filing |
| UX target | Trained compliance analyst / broker | Ops manager who does not know what a CF-28 is |
| Support | CBP support line | Email support with response SLA |
For any question of legal record — "what did CBP actually accept for this entry number," "what is the definitive transmitted certificate reference," "what is the response history on this line" — ACE is authoritative by definition and no third-party tool can substitute for it. Every importer needs an ACE account, and every operations team should periodically pull ACE reports directly. A broker uses ACE constantly; an importer with in-house compliance staff uses it weekly.
For the working-week question — "are the shipments I have coming in over the next 30 days covered by valid CPSC certificates, and is anything missing before it becomes a CF-28" —EntryProof is the right layer and ACE is not built to answer that. ACE will tell you what you filed; EntryProof tells you what you are about to file and what is likely to bite you. That is a different question, and it is the one the ops manager without a compliance background actually has.
This is a hypothetical scenario, not a real customer case. An importer's broker files 15 entries in a month across three product families. One family (a children's toy line) is subject to 16 CFR Part 1501 small-parts testing; the broker's templated CPC reference on file was for the prior season's product and does not cover the reformulated 2026 version. All 15 entries release. Two months later a CBP CF-28 lands requesting substantiation for one of the toy entries; the importer discovers the CPC gap only then. Pulling the ACE report retroactively confirms the reference was stale; EntryProof run against the pre-shipment packing list would have flagged the mismatch before any of the entries filed.
EntryProof is a data preparation and readiness-assessment tool for the CPSC Product Registry. EntryProof is NOT a customs broker, NOT a testing laboratory, and NOT a legal-advice service. Compliance decisions remain the responsibility of the importer. EntryProof does not guarantee that any classification, packet, or filing will be accepted by CPSC or CBP.
EntryProof is not affiliated with the U.S. Consumer Product Safety Commission (CPSC), U.S. Customs and Border Protection (CBP), Amazon, Shein, Temu, or TikTok Shop. References to the CBP ACE Portal are nominative-fair-use for the sole purpose of comparing capabilities of a government system to those of the EntryProof product.
In CBP's own words at https://www.cbp.gov/trade/automated/getting-started (checked September 14, 2026): "The ACE Secure Data Portal is a free, web-based access point designed to connect CBP, trade partners and Partner Government Agencies." CBP adds that the portal "gives users access to more than 400 reports that can be used to evaluate compliance and monitor daily operations," and that it "is primarily a resource through which users can monitor their CBP data," with entries and entry summaries filed through Electronic Data Interchange rather than through the portal.
Yes. ACE Portal access is free to any importer who registers. That is the case for the fee.
No. CBP describes the portal as a place to "monitor their CBP data" and run reports (cbp.gov/trade/automated/getting-started, checked September 14, 2026); it does not describe an alerting product. It does not surface an alert when an importer's CPSC eFiling data was structurally incomplete, when an HTS code the importer regularly ships moves onto a PGA-required list, or when a certificate reference is stale. Errors surface as CBP CF-28 requests for information or CF-29 notices of action — after the fact, in the mail or in the ACE inbox the importer may or may not check.
CBS News reported on the launch of CBP's CAPE tariff-refund platform, which went live Monday, April 20, 2026, in "Tariff refund portal off to bumpy start as some businesses report glitches" by Megan Cerullo (updated April 21, 2026, https://www.cbsnews.com/news/tariff-refund-portal-system-trump-cape-cbp/). In that article, Beth Benike, co-founder of Busy Baby, described spending more than four hours on hold and hitting a "Duplicate tax ID" error, and Rick Woldenberg of Learning Resources described receiving the message "The system is currently experiencing high volume, please try again later." CBP told CBS News it was looking into reports of problems. Those are the experiences of the named individuals as reported by CBS News, not a general finding about CBP systems, and we do not publish any broader claim about ACE quality that we cannot source.
No, and it cannot — ACE is the government system of record for U.S. imports, and every formal entry passes through it as a matter of law. EntryProof reads ACE-adjacent data and CPSC-side certificate data to produce readiness alerts before the ACE filing goes in. EntryProof is a layer above; ACE is the settlement layer below.
Two things: (1) an importer-friendly interpretation of the raw entry data — "these 3 entries in the last 30 days are missing a linked CPC certificate; here is which SKU"; (2) proactive alerting tied to CPSC rule changes affecting the importer's actual product lines, not the entire tariff schedule. ACE holds the truth; EntryProof reads it back in the form an operations manager can act on.
