Customs Documents Field Guide (7501 / ACE / Customs Invoices)

Informational only — not legal advice.

May 2026 note: CAPE Phase 1 opened in ACE beginning April 20 for eligible IEEPA refunds, and the May 7 CIT ruling invalidated the separate Section 122 proclamation for the importer plaintiffs. Document collection is therefore more important, not less: users need entry-level records to separate IEEPA, Section 122 (9903.03.*), Section 232, Section 301, and ordinary duty lines. (CBP CSMS #68315804, CIT Slip Op. 26-47)

What you have

In practice, many importers start with a customs invoice (carrier duty/tax invoice or broker invoice/statement) or a multi‑page customs packet. The goal is to get to a complete entry record — ideally a Form 7501 PDF and/or an ACE entry summary export.

RefundArrow note: upload what you have — including customs invoices and packets — but expect the cleanest results when you can also obtain Form 7501 PDFs (with continuation sheets) and/or ACE exports.

Use the table below as a quick “pick your path.” (We list 7501 first because it’s the destination document, even if it’s not the most common starting artifact.)

Form 7501 (Entry Summary) PDF

If you have a 7501 PDF (and any continuation sheets), you’re usually close to a complete entry record.

What to extract (minimum):

• Entry number
• Entry date + port code
• Importer of Record (IOR) name + importer number
• HTS lines + Chapter 99 lines (if present)
• Duty/fee amounts

Common “gotcha”: liquidation status/date may not be shown on the 7501 image itself (you may need revenue data or an ACE export to confirm).

Customs invoice

“Customs invoice” commonly means one of:

• a carrier duty/tax invoice (“we advanced duties/taxes; here’s what you owe”), or
• a broker invoice/statement (fees + disbursements tied to entries), or
• (less often) a CBP/ACE statement/export.

Even when it’s not enough to finish analysis, a customs invoice is often the best lead document because it may contain the identifiers you need to retrieve the real entry record.

What to look for (high-signal fields):

• Entry number (sometimes labeled “Entry No.” / “Customs Entry” / “Entry Summary No.”)
• Tracking number / AWB / BOL
• Broker or carrier reference numbers (file numbers)
• Date range (ship/arrival/delivery dates or invoice period)
• Totals + advancement/disbursement fees (useful context, not a substitute for duty-by-line)

Quick decode: entry numbers + filer codes
If an invoice includes an entry number, it often follows XXX-NNNNNNN-N where XXX is the entry filer code and the last digit is a check digit.
(19 CFR 142.3a)

What to do next: use the invoice identifiers to get the entry record:

• If you have an entry number: ask the broker/forwarder/carrier for the 7501 PDF + continuation sheets and, if possible, an ACE entry summary export for that entry.
• If you don’t have an entry number: ask them to return an entry number list for the invoice period tied to your tracking/AWB/BOL and billing name/address.

Customs packet or blob of docs

If you have a “customs packet” (often a multi‑page PDF bundle), treat it like a search problem:

Try this first: use your PDF viewer search for:

• 7501
• Entry Summary
• CBP Form
• Entry No

What you may find inside:

• a 7501 image (sometimes buried),
• a duty/tax detail report,
• the commercial invoice + packing list,
• transport references (AWB/BOL).

What to do next: if you find a 7501, use the Form 7501 PDF path. If you don’t, use the Customs invoice path and focus on extracting entry numbers and references.

ACE export (CSV/Excel)

If you have an ACE export (or a broker export in CSV/Excel format), you’re usually in the best‑case scenario for bulk analysis.

Sanity checks:

• Does it include line-level tariff reporting (HTS + any Chapter 99 lines)?
• Does it include duty/fee amounts by line (or at least program-level duty detail)?
• If you need liquidation status/date: confirm whether you’re looking at an entry summary export vs revenue/statement data (they can be separate).

Tracking / AWB / BOL only

You can still get to a complete entry record with “just” shipment identifiers:

• Provide tracking/AWB/BOL + delivery address + date range.
• Ask the broker/forwarder/carrier to return entry numbers and the 7501/ACE entry summary data for those shipments.

The minimum entry record

This is the smallest set of fields that usually unlocks analysis (and determines what you need to request next):

Who’s involved (players)

Two quick distinctions help avoid 90% of confusion:

• Roles like “Importer of Record (IOR)” and “ultimate consignee” are identities on the entry summary.
• Parties like the shipper/seller, carrier, broker, and forwarder are organizations that may hold different pieces of the record.

Practical “who holds what” (typical, not universal):

Glossary (fast)

Document flow (how it moves between parties)

High-level lifecycle:

1. Commercial docs (shipper/seller ↔ buyer/IOR)
2. Transport docs (carrier/forwarder)
3. Release/entry artifacts (broker + CBP)
4. Entry summary (7501 / electronic equivalent) + payment/statement data
5. Post-entry notices/actions (Forms 28/29/4647), PSCs, protests

How to get a 7501 or ACE export

If you’re missing any parts of the minimum record, the most productive asks tend to be:

Ask for:

• Form 7501 PDFs including continuation sheets (if any)
• An ACE entry summary export (CSV/Excel) if available
• Confirmation of the IOR identity per entry (or who the filer was, if they weren’t the filer)

Then choose the fastest path:

1. Broker/forwarder path: if you know who handled clearance, start with them (they’re usually the fastest path to exports).
2. Carrier path: if all you have is a carrier invoice/packet, ask the carrier to confirm who filed and to provide any clearance packet they have.
3. ACE path (if you’re the IOR and have access): export entry summary and revenue/statement data as needed.

For broker-by-broker specifics, use the request guide cluster: /learn/tags/document-retrieval.

What to do once you have the 7501s / exports

• Build a simple entry list (entry number + entry date + IOR identity).
• Extract HTS + Chapter 99 lines and duty amounts.
• If liquidation status/date isn’t present, treat it as “still missing” and source it from revenue/statement data.
• Upload what you have — even customs invoices and packets can be valuable lead documents.
