CBP Form 7501 is the entry summary every U.S. importer (or their broker) files with CBP for each formal import entry. It contains the importer of record, the goods imported, the customs value, the HTS classification, the country of origin, and the duty calculation. The 7501 is the legal basis for the duty assessment and the source document for refunds, protests, and audits.
CBP Form 7501 is the most important customs document most importers never read. The broker files it; CBP processes it; the duty gets paid; the goods clear. Then five years later, a refund opportunity appears, an audit lands, or a classification gets challenged – and the 7501 is the document everyone goes back to.
This guide walks through Form 7501 box by box, explains what each value means and where it comes from, and flags the lines most likely to be wrong on any given entry.
What Form 7501 is and when it is filed
Form 7501 (the “Entry Summary”) is filed with CBP for every formal entry – generally any commercial import valued at $2,500 or more. It is filed electronically through ACE (Automated Commercial Environment), typically by the importer’s customs broker, within 10 working days of entry.
The 7501 is distinct from the entry itself. The “entry” is the act of presenting goods for clearance (typically Form 3461 or its electronic equivalent). The 7501 is the formal accounting that follows – declaring exact classification, value, and duty owed.
The boxes that matter most for duty
Box 1: Filer Code / Entry Number
The unique entry number assigned by CBP. The first three characters are the filer code (broker or self-filer). This is what you need to look up an entry in ACE or to file a refund/protest later.
Box 2: Entry Type
Two-digit code identifying the entry type – e.g., 01 for consumption, 02 for consumption with quota, 03 for antidumping/countervailing, 06 for FTZ withdrawal. The type determines which rules apply.
Box 3: Summary Date
Date 7501 was filed. Note: this is not the entry date; the entry date is in box 2 area depending on form version, or referenced from the underlying 3461.
Boxes 5-7: Importer / Consignee / Importer Number
Identifies the importer of record (the legally responsible party). Importer Number (box 7) is the IRS EIN of the importer. This party owes the duty.
Box 13: Manufacturer ID
CBP-formatted manufacturer identifier. Required and often wrong. Matters for AD/CVD and for some trade preference claims.
Box 14: Exporting Country
The country from which the goods were last shipped to the U.S. NOT the same as country of origin (box 27).
Box 27: Country of Origin
The country where the goods were grown, manufactured, or substantially transformed. This is what triggers Section 301 (China-origin), AD/CVD orders, GSP, USMCA preferences. The single most-scrutinized field on the form.
Box 28: HTS Number
The 10-digit HTS classification. The basis for the entire duty calculation. Errors here are the largest source of duty disputes.
Box 31: Customs Value
The dollar value on which duty is calculated. Typically transaction value (price paid plus adjustments). See /how-to-calculate-import-duty/ for the full rules.
Boxes 35-37: Duty Breakdown
The calculated duty by line: base rate, Section 232, Section 301, Section 122, AD/CVD, MPF, HMF. This is the breakdown you reference for refund claims (only specific lines are refundable through any given mechanism).
How to pull a Form 7501 you do not have
- Ask your customs broker – they retain 7501s on file (5-year regulatory retention).
- Log into ACE Portal as the importer of record and pull entry history under your importer number.
- For older entries (pre-ACE), file a FOIA request with CBP for the entry record. Slow but works.
The five most common 7501 errors
- Wrong country of origin in box 27 (often confused with country of export in box 14). Drives wrong Section 301, USMCA, AD/CVD treatment.
- Wrong HTS in box 28. Single biggest source of duty overpayment and audit findings.
- Wrong importer of record number in box 7. Causes refund delays – refunds go to the listed importer, who may not be your operating entity.
- Customs value (box 31) computed without proper additions (assists, royalties, packing). Leaves the importer exposed to underpayment penalties.
- Manufacturer ID (box 13) wrong or generic. Triggers AD/CVD scope review and slows USMCA refund processing.
When to review 7501s on your own filings
Most SMB importers should run a quarterly review of their 7501s – pull a sample of 10-20 entries per quarter and verify the HTS, country of origin, customs value, and importer of record fields. The review cost is low; the rate of recoverable findings is typically 1-3% of duty paid.
For audit preparation, refund analysis, or pre-acquisition diligence, review the full year of 7501s. Patterns of misclassification or valuation errors compound across SKUs.
Frequently asked questions
Where can I see my own 7501s?
Through ACE Portal if you are registered as the importer of record. Through your customs broker (they retain on file for 5 years). For older entries, file a FOIA with CBP.
Who is responsible for the 7501 – the importer or the broker?
The importer of record is legally responsible. The broker files as the importer’s agent under power of attorney. Errors on the 7501 are the importer’s legal responsibility regardless of who filed it.
How long do I have to correct a 7501?
Before liquidation, you can amend through a Post Summary Correction (PSC). After liquidation, you have 180 days to file a protest under 19 U.S.C. § 1514. Beyond that, options are narrow (reliquidation under § 1520, or specific refund mechanisms like the current IEEPA refund).
What is the difference between Form 7501 and Form 3461?
3461 is the entry document presented at port to clear the goods (often electronic). 7501 is the entry summary filed within 10 working days, declaring full classification, value, and duty. The 7501 is the legal accounting; the 3461 is the operational clearance.
Can the broker change my 7501 without telling me?
Brokers can amend before liquidation through a PSC. As the importer, you should require notification of any amendment – it changes your duty exposure and your audit posture. Broker engagement letters should specify amendment notification.
