What is a 7501 form for customs purposes? It is the Entry Summary, the document that reports the value, classification, and duty computation for imported merchandise and triggers CBP’s assessment of the duties, taxes, and fees owed on that entry. Every formal entry needs one, filed within 10 working days of the merchandise’s release from CBP custody, with the estimated duties, taxes, and fees deposited at the same time.
This guide walks through what the form actually reports, block by block, in plain English: who has to file it, when it’s due, how MPF and HMF get computed on top of duty, and how the numbers it reports connect to liquidation months later. It also covers where the form fits alongside the customs bond and power of attorney a broker needs on file before it can touch an entry at all.

What CBP Form 7501 Is For
CBP uses Form 7501 to determine the appraisement, classification, and origin of imported merchandise, and to compute the duties, taxes, and fees due on it. It is a different document from the entry paperwork filed to get cargo released from CBP custody in the first place; the entry gets the goods off the port, the entry summary is what CBP actually uses to assess what’s owed and to compile official US import statistics.
That distinction matters operationally. A shipment can be released on an entry filing well before the entry summary and its duty payment are due, which is exactly why the two steps have separate deadlines inside the same customs clearance process.
For a shipment with more articles than fit on the base form, CBP Form 7501 comes with continuation sheets that repeat the commodity-line fields for additional entries, so a single entry summary can span several pages without changing anything about how it’s filed or when it’s due.
Who Files It, and When
Most entry summaries are filed by a licensed customs broker acting on the importer’s behalf, though an importer with the systems and expertise to do it can self-file. Either way, the filer must have the importer’s authorization on file, and for a broker that means a valid power of attorney; the filer of record is legally accountable for what the form reports.
CBP Form 7501 is generally due, along with the estimated duties, taxes, and fees it reports, within 10 working days of the merchandise’s release from CBP custody. Missing that window is a compliance problem in its own right, separate from whatever duty is ultimately owed. Our licensed customs brokerage team files entry summaries on this schedule as a matter of course for every client on file.
The Header Blocks: Entry Number, Entry Type, and Bond
The top of the form identifies the transaction. The entry number is an 11-digit alphanumeric identifier made up of a three-digit filer code assigned to the broker or importer, a seven-digit number unique to that filing, and a one-digit check digit computed from the preceding ten characters.
The Entry Type Code is a two-digit field where the first digit signals the general category of entry being filed, for example a consumption entry, an informal entry, or a warehouse entry, and the second digit refines that further. Nearby blocks record the summary date, the entry date, the surety number backing the transaction (or a code indicating none applies), and the bond type code, tying the filing directly back to the customs bond on file for that importer.
The Importer Number and Who's Accountable
The form also records the Importer of Record number, the identifier CBP uses to tie the entry to a specific importer for duty billing, compliance history, and statistics. That number is either the importer’s IRS-issued Employer Identification Number, a Social Security Number for an individual importer, or a CBP-assigned number for an importer that has neither, which is the usual case for a non-resident importer shipping into the US for the first time.
Whoever that number belongs to carries the legal weight of the filing. Under 19 U.S.C. 1484, the importer of record is required to make entry using reasonable care and to supply the information CBP needs to determine admissibility and assess duty, and that duty runs to the importer even when a broker prepares and files the paperwork.
The Commodity Lines: HTS Provisions and Duty Computation
Further down the form, each line item describes a specific article on the shipment and reports the HTS number that classifies it, the country of origin, the quantity, and the entered value. The duty rate attached to that HTS number, multiplied against the entered value, is what produces the duty amount owed on that line.
Getting the classification right on this section is what everything downstream depends on: the wrong HTS number produces the wrong duty rate, which produces the wrong amount deposited, which is exactly the kind of error CBP can catch and correct well after the goods have already cleared.
A single entry summary commonly carries several line items rather than one, particularly on a consolidated shipment covering more than one product or invoice. Each line is classified, valued, and duty-computed separately, so an entry summary for a mixed container can carry a dozen different HTS numbers and duty rates within a single filing, all of which have to reconcile back to the total duty deposited.
MPF and HMF: The Fees Stacked on Top of Duty
Two federal user fees ride alongside duty on most entry summaries. The Merchandise Processing Fee applies to formal entries at 0.3464% of the entered value, excluding freight and insurance, subject to a minimum and maximum that CBP adjusts periodically for inflation; for fiscal year 2026 that range runs from $33.58 to $651.50, effective October 1, 2025. Informal entries pay a smaller flat fee instead of the ad valorem calculation.
The Harbor Maintenance Fee applies only to cargo arriving by vessel, at 0.125% of the entered value, with no minimum or maximum cap. It does not apply to air, truck, or rail shipments. Both fees are computed and reported on the entry summary alongside duty, and both get deposited on the same 10-working-day schedule.
A manual, paper-filed entry summary also carries its own added surcharge on top of the standard MPF calculation, which is one more reason nearly every broker files electronically through CBP’s Automated Commercial Environment rather than on paper. None of these fees are optional or negotiable; they are statutory charges computed the same way for every filer submitting the same entry type.
| Block | What It Captures |
|---|---|
| 1 | Entry number: 3-digit filer code + 7-digit unique number + 1 check digit |
| 2 | Entry Type Code: first digit signals consumption, informal, or warehouse entry |
| 3, 7 | Summary date and entry date |
| 4, 5 | Surety number and bond type code |
| 23 | Importer of Record number (EIN, SSN, or CBP-assigned number) |
| Commodity lines | HTS number, country of origin, entered value, duty rate and amount |
From Entry Summary to Liquidation
The duty, MPF, and HMF paid when Form 7501 is filed are a deposit of estimated amounts, not a final bill. CBP has up to one year from the date of entry to liquidate it under 19 U.S.C. 1504(a), the point at which the duty assessment becomes final, and CBP can extend that window where more time is needed to verify classification, value, or origin.
Between filing and liquidation, corrections can still be made. An importer who spots an error in entered value, classification, or a duty computation can generally file a post summary correction before liquidation, rather than waiting for a formal protest afterward. That window is also why accurate HTS classification on the front end, backed by a binding ruling where the code is genuinely in doubt, is worth more than fixing the number later.
Frequently Asked Questions
What is a 7501 form for customs?
It is the CBP Entry Summary, the document that reports the value, HTS classification, and country of origin of imported merchandise and computes the duties, taxes, and fees owed on it. It is filed separately from, and after, the paperwork used to release the cargo itself.
Who is required to file CBP Form 7501?
A licensed customs broker filing on the importer’s behalf, or the importer itself if it self-files. Either way, the filer needs the importer’s authorization, and a broker specifically needs a valid customs power of attorney on file before it can file the entry.
How long do you have to file an entry summary?
Form 7501 and the estimated duties, taxes, and fees it reports are generally due within 10 working days of the merchandise’s release from CBP custody.
What is the difference between the entry and the entry summary?
The entry is the filing used to release merchandise from CBP custody at the port. The entry summary, Form 7501, is the separate filing that reports classification, value, and origin and computes the duties, taxes, and fees actually owed.
What fees appear on Form 7501 besides duty?
The Merchandise Processing Fee, 0.3464% of entered value on formal entries with a periodically adjusted minimum and maximum, and the Harbor Maintenance Fee, 0.125% of entered value with no cap, which applies only to ocean cargo.
When does an entry summary become final?
At liquidation, which CBP generally completes within one year of the date of entry under 19 U.S.C. 1504(a), though CBP can extend that period. Liquidation is when the duty assessment becomes final rather than an estimate.
Can I fix a mistake on an entry summary after it's filed?
Yes, generally through a post summary correction filed before liquidation, which is faster and simpler than a formal protest filed after liquidation. Catching an error in classification, value, or duty computation early, before the entry liquidates, keeps the correction process straightforward.
