Key Takeaways Explain This Topic AI
Under 19 CFR 142.12, the Entry Summary (CBP Form 7501) must be filed and estimated duties, taxes, and fees deposited within 10 working days after the date of cargo release.
A 'working day' under 19 CFR 101.1 strictly excludes Saturdays, Sundays, and national legal holidays, distinguishing it from the 15-calendar-day arrival entry window.
Under 19 CFR 24.5, every importer of record and ultimate consignee must have an active CBP Form 5106 on file with CBP before an entry summary can be processed.
In ACE, a rejected entry summary must be returned in valid status with payment within two working days of the rejection under the ACE Entry Summary Business Rules and Process Document; if the rejection occurred before the 10th day of the filing period, the filer has the remainder of that period but never less than two working days.
Importers participating in the Periodic Monthly Statement (PMS) program settle consolidated monthly duties on or before the 15th working day of the month following cargo release under 19 CFR 24.25.

4.3 Entry Summary, CBP Form 7501, and Automated Commercial Environment
Quick Answer: Under 19 CFR 142.12, the Entry Summary (CBP Form 7501) must be filed and estimated duties, taxes, and fees deposited within strictly 10 working days from the date of cargo release. A working day under 19 CFR 101.1 excludes Saturdays, Sundays, and federal holidays. Every entry summary requires an active CBP Form 5106 (Importer Identity) on file for both the Importer of Record and Ultimate Consignee under 19 CFR 24.5. When an electronic entry summary transmission is rejected by CBP, the filer generally has two working days from the rejection to correct and retransmit the summary in valid status with payment, under the ACE Entry Summary Business Rules and Process Document — one of the references CBP designates for the exam. Revenue settlement occurs through Automated Clearinghouse (ACH) Daily Statements or Periodic Monthly Statements (PMS) , with PMS payments due on or before the 15th working day of the month following the month of release (19 CFR 24.25).
Statutory and Regulatory Mandate: 19 CFR 142.12
While CBP Form 3461 governs the physical release of cargo from carrier custody, CBP Form 7501 ("Entry Summary") is the fundamental revenue and legal document of the customs clearance process. Under 19 CFR 142.12 , the Importer of Record is legally mandated to:
- File the formal entry summary documentation or electronic ACE equivalent;
- Present commercial invoices and necessary Partner Government Agency (PGA) licenses;
Deposit estimated customs duties, Internal Revenue taxes, Merchandise Processing Fees (MPF), and Harbor Maintenance Fees (HMF).
The 10-Working-Day Rule
The statutory clock begins on the date of release . Under 19 CFR 101.1 , a "working day" is defined as any day other than a Saturday, Sunday, or national legal holiday. If merchandise is released on a Wednesday, the 10-working-day period skips intervening weekends and any official federal holiday. Failure to file the entry summary and deposit duties within this 10-working-day window constitutes a breach of the customs bond condition (19 CFR 113.62), subjecting the importer and surety to liquidated damages under 19 CFR 142.15 and potential revocation of immediate delivery release privileges under 19 CFR 142.26.
Detailed Anatomy of CBP Form 7501
CBP revised the Entry Summary form to CBP Form 7501 (02/26) , and the revision renumbered the line-item blocks when four new metal-origin fields were inserted at blocks 21 through 24. Candidates must know both numbering schemes: the current form governs practice, while released exams from earlier sittings (and the answer keys published with them) use the pre-2026 numbering. Confirm which revision is in force for your own examination date.

The Pre-2026 Numbering You Will See on Released Exams
Before the melt-and-pour fields were added, blocks 21 through 40 ran as follows. This is the numbering used by, for example, the April 2026 released examination, which asked how "Blocks 27–34" should be completed for two line items:
- Pre-2026 Block Field Name Current 02/26 Equivalent
- 21 Location of Goods / G.O. No. 25
- 22 Consignee No. 26
- 23 Importer No. 27
- 24 Reference No. 28
- 25 Ultimate Consignee Name and Address 29
- 26 Importer of Record Name and Address 30
- 27 Line No. 31
- 28 Description of Merchandise 32
- 29 A. HTSUS No. / B. AD-CVD No. 33
- 30 A. Gross Weight / B. Manifest Qty. 34
- 31 Net Quantity in HTSUS Units 35
- 32 A. Entered Value / B. CHGS / C. Relationship 36
- 33 A. HTSUS Rate / B. ADA-CVD Rate / C. IRC Rate / D. Visa No. 37
- 34 Duty and I.R. Tax 38
- 35 Total Entered Value 39
- 36 Declaration of Importer of Record 40
- 37 / 38 / 39 / 40 Duty / Tax / Other / Total 41 / 42 / 43 / 44
STUDY METHOD: Memorize the sequence of line-item fields — line number, description, HTSUS and AD/CVD number, gross weight and manifest quantity, net quantity in HTSUS units, entered value with CHGS and relationship, the rate column, then duty and IR tax — and then anchor the sequence to whichever revision your exam uses. The order never changes; only the numbers shift by four.
User fees do not have their own line-item block. Merchandise Processing Fee (class code 499 ) and Harbor Maintenance Fee (class code 501 ) are reported in the Other Fee Summary box that feeds the "Other" total.
The Manufacturer Identification (MID) Code Construction Algorithm
When filing Block 13, filers must derive the MID using CBP's mandatory 5-step rule:
Country Code: 2-character ISO country code (e.g., Japan = JP , Germany = DE , China = CN ).
Manufacturer Name: First 3 characters of the first two words of the company name (e.g., KYOTO PRECISION = KYOPRE ). If the name consists of only one word, take the first 6 characters.
Street Address: Largest numerical digits from the street address up to 4 digits (e.g., 1245 Sakura Boulevard = 1245 ; if no numbers exist, ignore this element).
City Name: First 3 characters of the city (e.g., TOKYO = TOK ).
Example: Kyoto Precision Robotics, 1245 Sakura Blvd, Tokyo, Japan yields MID: JPKYOPRE1245TOK .
Commercial Invoice Legal Requirements (19 CFR Part 141, Subpart F)
Under 19 CFR 141.86 , a commercial invoice presented with CBP Form 7501 must be prepared in English (or accompanied by an accurate English translation) and state the following mandatory commercial data elements:
Port of Entry: The U.S. port to which the goods are destined;
Parties: Detailed legal names and physical addresses of both the seller and buyer (or sender and receiver if not a purchase);
Commercial Description: A detailed description of the merchandise, including commercial trade names, grades, and quality specifications enabling proper HTSUS classification;
Quantities: Quantities stated in the weights and measures of the exporting country and the official HTSUS units of quantity;
Purchase Price / Values: The purchase price of each item in the currency of the sale, or the value if goods are not shipped pursuant to a purchase;
Itemized Charges: All charges upon the merchandise itemized by name and amount (including international freight, marine insurance, export packing, and buying/selling commissions);
Country of Origin: The country of origin of the merchandise;
Assists and Rebates: All assists furnished by the buyer free or at reduced cost (19 U.S.C. § 1401a(h)), and all rebates, drawbacks, or bounties allowed upon exportation.
Missing Invoices: Pro Forma Invoices and Missing-Document Bonds (19 CFR 141.85, 141.66, 113.43)
If the required commercial invoice is unavailable when the entry summary is filed, the filer may present a pro forma invoice under 19 CFR 141.85 , which contains an undertaking to produce the required invoice. Where a bond is given for the production of missing documentation, it is executed on CBP Form 301 with the conditions of 19 CFR 113.62 or 113.69 (19 CFR 141.66), and the missing document must be delivered within 120 days from the date of the CBP notice requesting it . Under 19 CFR 113.43, the port director may, on written application, grant one further extension not to exceed 60 days . The missing document is identified in the Missing Docs block of the entry summary (block 18 on both the current and pre-2026 revisions).
CBP Form 5106: Importer Identity Creation and Maintenance (19 CFR 24.5)
Under 19 CFR 24.5 , no entry or entry summary will be accepted by CBP until the Importer of Record and Ultimate Consignee have registered their legal identities on CBP Form 5106 ("Create/Update Importer Identity Form").
- Entity Identification Hierarchy
- U.S. Corporations and Partnerships: Internal Revenue Service Employer Identification Number ( IRS EIN );
- U.S. Individuals: Social Security Number ( SSN );
Nonresident Entities / Foreign Importers: CBP-Assigned Number , generated by submitting a formal CBP Form 5106 to CBP's Revenue Division.
Under modern Trade Facilitation and Trade Enforcement Act (TFTEA) regulations, Form 5106 requires extensive beneficial ownership disclosures, corporate officer contact information, primary banking details, and company structure data to combat illicit shell corporations, customs fraud, and duty evasion under 19 U.S.C. § 1592.
Automated Commercial Environment (ACE): Rejections and Payment Mechanics
The Automated Commercial Environment (ACE) serves as the primary electronic single window for all customs transactions in the United States.
Entry Summary Rejections and the 2-Working-Day Rule (ACE Entry Summary BRPD)
If an electronic entry summary fails automated ACE validations, contains classification errors, or is rejected on review by a CBP import specialist at a Center, the filer receives an electronic rejection notice. The governing authority is the ACE Entry Summary Business Rules and Process Document — one of the references CBP designates for the exam — not 19 CFR 142.13, which addresses when an entry summary must be filed at the time of entry .
A rejected entry summary must be returned to CBP in valid status, with payment if applicable, within two (2) working days from the date of the rejection . Generally the filer has two working days after the day of the reject.
The exception that CBLE questions turn on: if the entry summary was originally submitted and rejected before the 10th day of the filing period , the filer has the remainder of the 10-working-day period to resubmit — but in no case less than two working days . Whichever period is longer controls. A rejected summary received after the applicable window may generate a late-file liquidated damages case under 19 CFR 142.15.
Duty Payment Modalities: ACH Daily vs. Periodic Monthly Statement (PMS)
Customs revenue settlement in ACE occurs electronically through the Automated Clearinghouse (ACH): ┌──────────────────────────────────┐

- └───────────────────────────┘ └───────────────────────────┘
ACH Daily Statement: Entries are batched onto a daily statement. The broker or importer authorizes payment, and the U.S. Treasury debits the designated bank account within the standard 10-working-day window following cargo release.
Periodic Monthly Statement (PMS — 19 CFR 24.25): Eligible importers maintaining continuous customs bonds may enroll in the PMS program. Under PMS, all entries released during a calendar month are consolidated onto a single monthly statement. Payment of all duties, taxes, and fees on the consolidated statement is statutorily due on or before the 15th working day of the month following the month of release . This provides importers with significant commercial working capital flexibility without incurring interest charges under 19 U.S.C. § 1505.
