Continuous Activity Code 1 Bond Amount Calculations

The required face amount (penal sum) of a customs bond is established in accordance with CBP Monetary Guidelines for Determining Bond Amounts. For an Activity Code 1 Continuous Bond (Importer or Broker), CBP utilizes a standardized mathematical formula tied directly to the importer's revenue liability:

The Standard 10% Continuous Formula

1. Statutory Floor: The absolute minimum face amount for a Continuous Activity Code 1 Bond is $50,000.
2. The 10% Calculation Base: The base calculation is equal to 10% of the total customs duties, excise taxes, and government user fees (Merchandise Processing Fee and Harbor Maintenance Fee) paid by the importer of record during the preceding 12 calendar months (or projected to be paid during the upcoming 12 months for a new commercial importer).
3. The Two-Tier Rounding Rule:
   • Amounts Up to $100,000: If the calculated 10% base is between $50,001 and $100,000, the result must be rounded UP to the next higher multiple of $10,000.
   • Amounts Exceeding $100,000: If the calculated 10% base exceeds $100,000, the result must be rounded UP to the next higher multiple of $100,000.

Step-by-Step Mathematical Calculation Examples

• Scenario A (Under the Floor): Importer pays $280,000 in total duties, taxes, and fees over 12 months.
  • 10% calculation: $280,000 × 0.10 = $28,000.
  • Because $28,000 is less than the statutory floor, the required bond amount is $50,000.
• Scenario B (Rounding to Nearest $10,000): Importer pays $645,000 in total duties, taxes, and fees over 12 months.
  • 10% calculation: $645,000 × 0.10 = $64,500.
  • Because $64,500 falls between $50,000 and $100,000, round UP to the nearest $10,000.
  • Required bond amount is $70,000.
• Scenario C (Exceeding $100,000 Base): Importer pays $1,340,000 in total duties, taxes, and fees over 12 months.
  • 10% calculation: $1,340,000 × 0.10 = $134,000.
  • Because $134,000 exceeds $100,000, round UP to the nearest $100,000 increment.
  • Required bond amount is $200,000.
• Scenario D (Exact Multiple): Importer pays $3,000,000 in total duties, taxes, and fees over 12 months.
  • 10% calculation: $3,000,000 × 0.10 = $300,000.
  • Because $300,000 is an exact multiple of $100,000, no rounding up is required.
  • Required bond amount is $300,000.

Single Transaction Bond (STB) Calculation Formulas

When an importer elects or is required to utilize a Single Transaction Bond (STB) on CBP Form 301, the bond face amount is determined by evaluating the legal nature of the imported commodity:

1. Standard Commercial Merchandise (Unrestricted)

For ordinary, unrestricted commercial merchandise, the statutory STB formula is:

$\text{STB Amount} = \text{Total Entered Value} + \text{Estimated Duties, Taxes, and User Fees}$

Worked Calculation: An importer brings in a single shipment of commercial furniture with an entered customs value of $85,000. The duty rate is 4.0%, so duty is $3,400.00. The Merchandise Processing Fee is $85,000 × 0.003464 = $294.44, which falls between the FY 2026 caps of $33.58 and $651.50. Total duties and fees are $3,694.44, so the computed STB penal sum is $85,000.00 + $3,694.44 = $88,694.44, which CBP will set at a rounded figure (commonly the next $1,000, i.e. $89,000) in accordance with port practice.

2. Quota, Restricted, or Partner Government Agency (PGA) Goods (The 3× Value Rule)

If merchandise is subject to tariff-rate quotas, import restrictions, absolute quotas, or conditional release under the jurisdiction of a Partner Government Agency (PGA)—such as the Food and Drug Administration (FDA), Environmental Protection Agency (EPA), U.S. Department of Agriculture (USDA-APHIS), or Consumer Product Safety Commission (CPSC)—the formula changes dramatically:

$\text{STB Amount} = 3 \times \text{Entered Value}$

Worked Calculation: An importer imports medical surgical instruments subject to FDA medical device regulations, with an entered customs value of $120,000 and estimated duties of $3,600. Because the goods are conditionally released subject to FDA admissibility determination, the STB formula is strictly three times the entered value: $\text{STB Amount} = 3 \times \$120,000 = \$360,000$ Note: Duties, taxes, and fees are not added to the 3× calculation; the penal sum is strictly based on the merchandise value.

Automated Bond Sufficiency Reviews and the 15-Day Cure Protocol

The CBP Revenue Division constantly monitors continuous bonds through automated risk-profiling algorithms in ACE. The system recalculates an importer's rolling 12-month duty liability every month. If an importer's duty payments spike—due to business expansion, increased tariff rates under Section 301, Section 232, or newly imposed Antidumping/Countervailing Duties (AD/CVD)—ACE flags the bond as insufficient.

The Notice of Insufficiency Workflow

1. Issuance of Notice: CBP issues an official Notice of Insufficiency electronically via ACE and in writing to both the principal and surety, formally demanding an increase in the continuous bond amount.
2. The Mandatory 15-Day Clock: Under CBP policy and operational directives, the principal has strictly 15 calendar days from the date of the written notice to cure the deficiency. The principal must file a bond rider or a superseding continuous bond in the increased penal sum approved by the Revenue Division. Riders and replacement bonds are executed on CBP Form 301 and transmitted through the ACE bond module; there is no separate "Form 301A."
3. Sanctions for Non-Compliance: If the bond is not increased within 15 calendar days, CBP deactivates the continuous bond in ACE. The importer is immediately blocked from utilizing the bond for paperless cargo releases. Every subsequent shipment arriving at any U.S. port will be detained unless the importer posts an STB for each entry (at 3× value or value plus duty) or diverts the cargo to a bonded warehouse at significant expense.

Breach of Bond Conditions and Liquidated Damages

A customs bond is not a statutory fine statute; it is a contract. When a condition of CBP Form 301 (codified in 19 CFR 113.62) is violated, the government does not issue a criminal penalty. Instead, CBP asserts a claim for liquidated damages against the principal and surety.

Prominent Grounds for Liquidated Damages Assessment (19 CFR 113.62)

1. Failure to Redeliver Merchandise (19 CFR 113.62(d)):
   • If CBP or a PGA determines that released merchandise is misbranded, contaminated, defective, or inadmissible, CBP issues CBP Form 4647 (Notice to Mark and/or Notice to Redeliver).
   • The demand must be made within the period fixed by the applicable paragraph of 19 CFR 141.113: 30 days for merchandise not legally marked, 180 days for textiles and textile products whose origin was misrepresented, and for FDA-regulated food, drugs, devices, cosmetics, and tobacco, the earliest of FDA refusal, FDA clearance, or 30 days after release. No demand may be made after the liquidation of the entry has become final (19 CFR 141.113(h)).
   • Assessment Amount: If the importer fails to redeliver the goods into CBP custody, liquidated damages are assessed in an amount equal to three times the entered value (3× value) for restricted, quota, or PGA goods, or equal to the entered value for unrestricted goods.
2. Late Entry Summary and Duty Deposit (19 CFR 113.62(b)):
   • Importers must file CBP Form 7501 and deposit estimated duties within 10 working days of physical release (19 CFR 142.12(b)).
   • Failure to file timely entry summary results in liquidated damages assessed per entry, typically based on statutory formulas or interest assessments.
3. Failure to Produce Required Documentation (19 CFR 113.62(c)):
   • Failure to tender required commercial invoices, PGA certificates, or proofs of origin within the applicable window — for documents covered by a missing-document bond, within 120 days of the CBP notice requesting them (19 CFR 113.43), extendable once by up to 60 days.

Liquidated Damages vs. Statutory Penalties (19 U.S.C. § 1592)

Candidates must never confuse liquidated damages with Section 1592 civil penalties:

Administrative Petitions for Relief and Mitigation (19 CFR Part 172)

When liquidated damages are incurred, the CBP Fines, Penalties, and Forfeitures (FP&F) Officer issues CBP Form 5955A (Notice of Penalty or Liquidated Damages Incurred and Demand for Payment) to the principal and the surety.

The 60-Day Petition Deadline (19 CFR 172.3)

Under 19 CFR 172.3, the principal or the surety has strictly 60 calendar days from the date of the notice to:

1. Pay the full demanded liquidated damages amount; or
2. File a formal written Petition for Relief with the FP&F Officer requesting cancellation or mitigation.

Standards for Administrative Mitigation

CBP evaluates petitions under established administrative Mitigation Guidelines. Grounds for mitigation include:

• First-time breach with zero prior compliance violations.
• Documented evidence that merchandise was destroyed or exported prior to the redelivery notice.
• Extraordinary circumstances beyond the importer's control (e.g., natural disasters, strikes).
• Prompt corrective action eliminating all potential revenue loss.

Supplemental Petitions and Payment (19 CFR 172.41)

If the initial petition is denied, or relief is granted on conditions the petitioner will not accept, a supplemental petition may be filed within 60 calendar days from the date of the notice of the decision. Once a final mitigation decision is rendered, any mitigated amount assessed must be paid within 60 calendar days of the decision letter, or CBP will rescind the mitigation and demand full payment from the surety.
