Quick-reference table — code, type, method, expected duration, risk level.
| Code | Type | Inspection Method | Duration | Risk |
|---|---|---|---|---|
| 1A | Basic Doc ReviewRoutine document audit | Document audit | Hours – 2 days | ★ |
| 4A | Doc Review + OpenDoc audit + mandatory open inspection | Documents + transferred for opening | 3 – 7 days | ★★★ |
| 7H | Non-Intrusive ScanX-ray imaging | X-ray scan only | 2 – 3 days | ★★ |

5H is the AI-driven document review that quintupled in February. 9H launches May 1 and verifies the importer of record itself. Here's what changed and why it matters.
Documents reviewed first, then physical inspection. The ACE system now performs 100% AI cross-checking of invoice, B/L, and packing-list data. CBP set up a dedicated Fast Doc Review team for China-origin cargo.
Originated at LA / LB, now spread to Oakland, Savannah, Seattle, NY/NJ — every major port is affected.
Launched May 1, 2026. CBP no longer just inspects what's in the box — it verifies who the importer is. Goods can be released, but if the consignee fails verification, the entry stops.
The 9H notice goes only to the broker — not the seller. Sellers may not know they were caught until cargo is already detained.
| Comparison | 5H | 9H |
|---|---|---|
| Inspects | Goods + documents | Importer / consignee |
| Method | AI doc audit + open | Qualification check |
| Trigger | Doc inconsistency | Invalid company / Bond |
| Notice channel | Broker + freight forwarder | Broker only (hidden) |
| Resolution difficulty | ★★★☆☆ | ★★★★☆ |
| Return rate | 82% | Very high |


Most 5H / 9H holds trace back to one of seven preventable issues. Run this checklist before every container.
Different codes need different response speeds and tactics. Triage by severity.
Provide the requested supporting docs. Confirm container packing meets standards. Usually clears within a week.
Coordinate immediately with the customs broker. Compile a complete evidence chain (invoices, contracts, payment proof). Engage a customs attorney if value exceeds $50k.
Immediately provide EIN proof + active Bond. Broker submits state-government website screenshot + IRS EIN confirmation letter to CBP and requests human review.
