CPSC “Under Review”: Does It Stop Your Cargo, and What Happens Next?

No—not by itself. CPSC’s current 1USG guidance says Under Review signifies that the agency is electronically reviewing an entry for a product of interest. The message can delay CPSC’s 1USG status notification, but CPSC says the review does not affect cargo flow through the border unless an intensive examination is required and CBP concurs.

CPSC’s Detention FAQ states the same operational boundary: cargo may continue through the port while the entry is Under Review, subject to an approved CPSC exam request or an independent reason for CBP or another PGA to examine it.

That does not make Under Review a favorable compliance decision. The message does not establish that the product is compliant, admissible, properly certified, or released. It identifies the agency’s current review state. A later CPSC, CBP, or other-agency message can still change the route.

The first control, therefore, is to keep movement and release separate. Cargo may continue moving through the port while the legal or operational release status remains a different question.

CPSC describes 1USG as a status or PGA-paperwork-completion message. It describes ACE 1C as the release message to trade. In the agency’s words: “The 1C releases cargo, not the 1USG.”

That distinction prevents two opposite mistakes:

• treating Under Review as if cargo has already been stopped; and
• treating May Proceed or 1USG completion as if the separate ACE cargo-release signal has necessarily been received.

Use the CPSC Import Shipment Tracking Tool to check CPSC’s status, but do not use it as release evidence. CPSC expressly says tracker statuses are not official CPSC or CBP releases and directs trade to the customs broker or ABI messaging for official release information.

Even May Proceed has a defined limit. CPSC guidance says a manual notice can later request examination at the importer’s premises. That possibility does not predict how often a later examination occurs; it simply means May Proceed should not be described as permanent immunity from later CPSC action.

Read the exact message rather than treating every CPSC status as a hold. The current CPSC workflow separates review, disposition, document, examination and detention states because each one supports a different next action.

The row that controls is the row matching the actual message and any separate CBP or other-agency instruction. An expected sequence is not evidence that a particular entry has reached the next state.

CPSC publishes business-hour review periods, but they are not a universal cargo-release schedule. The June 2026 guidance distinguishes transport mode and whether the entry has additional risk factors.

CPSC calculates business hours from receipt of the entry using an 8 a.m.–4 p.m. business clock in the applicable port/staff time zone on days the Federal government is open. The public tracker, however, displays dates and times in U.S. Eastern Time. Do not use the tracker’s display timezone as if it were the calculation rule for every port.

A separate CPSC Detention FAQ states that, when the entry was not provided three or more business days before arrival, CPSC needs 8 business hours for air and 16 for ocean to review the data. The FAQ does not explain how that summary maps to the June 2026 risk-band table. Present the two official statements separately; do not convert either one into a universal service-level promise.

If CPSC takes no action within the applicable period, its guidance says the system sends May Proceed automatically. That still does not prove ACE 1C or remove another agency’s requirement. For an inquiry specifically about an Under Review message, the CPSC Import Contact Form instructs the user to wait at least 16 business hours before contacting the agency.

Use a two-track check rather than waiting on one screen.

1. Save the exact message and timestamp. Under Review, Hold Intact, a documents request, a confirmed CBP Hold and a detention notice are not interchangeable.
2. Check the CPSC tracker correctly. Enter the entry number with the filer code included and remove hyphens. Treat the result as CPSC status information, not official release evidence.
3. Ask the broker or filer for the separate release state. Confirm whether ACE 1C has been received and whether CBP or another PGA has placed an independent requirement or hold.
4. Read time in the correct context. Use the CPSC business clock for the review period and remember that the tracker displays Eastern Time. If the risk band is not visible, do not invent the shorter period.
5. Be ready to follow an exact documents or exam instruction. If the message identifies records for DIS, submit the listed records. If the broker sees a confirmed CBP Hold, follow that hold rather than the earlier review-only route.
6. Escalate without turning the clock into a promise. For an Under Review inquiry, wait at least 16 business hours before using CPSC’s contact form. A contact threshold is not a guaranteed disposition or release deadline.

This control produces an operational record: exact CPSC state, separate release state, any independent agency action, applicable clock context, and the next verified instruction. It does not produce a product-compliance or admissibility determination.

A Notice of Sampling and Detention is a new procedural event, not another name for Under Review. CPSC says the notice contains the reason for the detention and contact information for the investigator handling it.

The notice allows five working days for the recipient to respond, and CPSC says reasonable extensions may be allowed in some circumstances. The extension is not guaranteed. Use the notice itself and the investigator’s instructions rather than applying the earlier Under Review clock to the detention response.

CBP and CPSC can also detain under separate authorities and issue separate notices. Resolution by one agency does not automatically resolve the other agency’s detention. This article stops at that handoff; it does not provide the full detention, admissibility or protest analysis.

Under Review means CPSC is electronically reviewing the entry. It does not, by itself, stop cargo—and it does not release cargo. Keep the CPSC 1USG status and the ACE 1C release track separate, monitor the exact message, and move to a hold, documents, exam or detention route only when the verified signal requires it.
