Most importers never look at their entry summary. The broker files it, the goods clear, and the invoice gets paid. Then something goes wrong: a duty looks too high, a refund window opens, or CBP asks a question about a shipment from eight months ago. At that point the only document that connects what you paid to a specific entry is CBP Form 7501, the Entry Summary. It is the legal accounting document that declares the value of the shipment, identifies the goods by HTS code, calculates the duties owed, and records what was actually paid. Every line item on it is a data point in a refund claim, and every field on it exists because a regulation requires it, under 19 CFR 141.61, which governs the completion of entry and entry summary documentation.
The first thing to learn is that the form is a summary, not a receipt. A duty figure on the form is an entry detail, not proof of payment and not a refund approval. It tells you what was declared and calculated. Whether the money moved, and whether CBP accepted the entry, lives in other records. That distinction matters most when you are checking past entries for a possible recovery, because the form can identify the transaction for a broader document review, but it cannot establish eligibility on its own.
Read the header first, because it tells you which shipment you are looking at. Block 2 is the entry type, a two-digit code that classifies how the goods entered: 01 is a consumption entry, the standard commercial import, and 11 is an informal entry. Block 3 is the entry number, an 11-digit code made of a three-digit filer code, a seven-digit entry number, and a check digit. That number is what you reference when filing through CBP's systems and when pulling records from the ACE portal. Blocks 6 and 7 record two different dates: the date the goods arrived and the date the entry was filed. For refund purposes the controlling date is generally the date of entry, because that date determines which tariff orders were in effect when the duties were assessed. The dates on the 7501 are the dates CBP will use to adjudicate a claim, regardless of when the goods physically moved.
The line items are where the money lives. Each line covers one category of goods and carries the 10-digit HTS number the broker assigned, the country of origin, the entered value, and the duty rate applied. The HTS code determines the base duty rate and whether additional tariffs apply, so an error here flows into every number below it. Entered value is the customs value, typically based on the transaction value on the commercial invoice, and duty is calculated as a percentage of that number, so an error in value is an error in duty. Country of origin is separate from the country of export, and it is critical for determining which tariff regime applies. Read those three fields together on every line, and compare them against the commercial invoice and packing list before you accept the form as final.
Three blocks at the bottom of the form close the accounting. Block 35 is the total entered value for all line items. Block 37 is the total estimated duty paid, excluding antidumping and countervailing duties. Block 36 is the declaration of the importer of record, the person legally responsible for the accuracy of the entry, and Block 42 carries the broker or filer information. If a broker prepared the entry, that does not make the broker the importer of record. The importer of record owns the accuracy, and the signature on Block 36 is the signature that says so.
The practical habit is simple: pull your own copies through the ACE portal, or ask your broker for them, and read the header and one line item per shipment before the entry liquidates. Check that the entry number matches your shipment, the entry type is the one you expected, the HTS code is the one you classified, and the entered value matches the invoice. After the Supreme Court's February 2026 ruling on IEEPA tariffs opened a refund window for importers, the starting point for almost every successful claim was a 7501 the importer had never looked at closely. The form will not tell you whether you are owed money. It will tell you exactly where to look. If the VAT side of a European shipment is the gap, IOSS and the 150 euro line covers the threshold most US brands get wrong, and country of origin marking covers the label that holds a shipment at the border.
The Entry Summary, the legal accounting document your customs broker files with CBP after your goods clear the border. It declares the value of the shipment, identifies the goods by HTS code, calculates the duties owed, and records what was actually paid.
Block 3 of the form. It is an 11-digit code: a three-digit filer code, a seven-digit entry number, and a check digit. It is the number you reference when filing through CBP systems and when pulling records from the ACE portal.
No. A duty figure on the form is an entry detail, not proof of payment or a refund approval. The form identifies the transaction and shows what was declared and calculated, but eligibility and payment live in other records.
The date of entry, generally recorded in the header alongside the arrival date. That date determines which tariff orders were in effect when the duties were assessed, and it is the date CBP uses to adjudicate a claim.
