(1) Bills for vessel repair duties, reimbursable services and miscellaneous amounts. If payment is not received by CBP on or before the late payment date appearing on the bill, interest charges will be assessed upon the delinquent principal amount of the bill. The late payment date is the date 30 calendar days after the interest computation date. The interest computation date is the date from which interest is calculated and is initially the bill date.

(2) Interest on supplemental duties, taxes, fees, and interest -

(i) Initial interest accrual. Except as otherwise provided in paragraphs (b)(2)(i)(A) through (b)(2)(i)(C) of this section, interest assessed due to an underpayment of duties, taxes, fees, or interest will accrue from the date the importer of record is required to deposit estimated duties, taxes, fees, and interest to the date of liquidation or reliquidation of the applicable entry or reconciliation. An example follows:

Example:

Entry underpaid as determined upon liquidation

Importer owes $500 plus interest as follows:

The importer makes a $1,000 initial deposit on the required date (January 1) and the entry liquidates for $1,500 (December 1). Upon liquidation, the importer will be billed for $500 plus interest. The interest will accrue from the date payment was due (January 1) to date of liquidation (December 1).

(A) If a refund of duties, taxes, fees, or interest was made prior to liquidation or reliquidation and is determined upon liquidation or reliquidation to be excessive, in addition to any other interest accrued under this paragraph (b)(2)(i), interest also will accrue on the excess amount refunded from the date of the refund to the date of liquidation or reliquidation of the applicable entry or reconciliation. An example follows:

Example:

Pre-liquidation refund but entry liquidates for an increase

Importer owes $800 plus interest as follows:

The importer makes a $1,000 initial deposit on the required date (January 1) and receives a pre-liquidation refund of $300 (May 1) and the entry liquidates for $1,500 (December 1). Upon liquidation, the importer will be billed for $800 plus interest. The interest accrues in two segments: (1) On the original underpayment ($500) from the date of deposit (January 1) to the date of liquidation (December 1); and (2) on the pre-liquidation refund ($300) from the date of the refund (May 1) to the date of liquidation (December 1).

(B) The following rules will apply in the case of an additional deposit of duties, taxes, fees, or interest made prior to liquidation or reliquidation:

(1) If the additional deposit is determined upon liquidation or reliquidation of the applicable entry or reconciliation to constitute the correct remaining balance that was required to be deposited on the date the deposit was due, interest shall accrue on the amount of the additional deposit only from the date of the initial deposit until the date the additional deposit was made. An example follows:

Example:

Additional deposit made and entry liquidates for total amount deposited

Importer owes interest on $200 as follows:

The importer makes a $1,000 initial deposit on the required date (January 1) and an additional pre-liquidation deposit of $200 (May 1) and the entry liquidates for $1,200 (December 1). Upon liquidation, the importer will be billed for interest on the original $200 underpayment from the date of the initial deposit (January 1) to the date of the additional deposit (May 1).

(2) If the additional deposit is determined upon liquidation or reliquidation of the applicable entry or reconciliation to be less than the full balance owed on the amount initially required to be deposited, in addition to any other interest accrued under this paragraph (b)(2)(i), interest also will accrue on the remaining unpaid balance from the date deposit was initially required to the date of liquidation or reliquidation. An example follows:

Example:

Additional deposit made and entry underpaid as determined upon liquidation

Importer owes $300 plus interest as follows:

The importer makes a $1,000 initial deposit on the required date (January 1) and an additional pre-liquidation deposit of $200 (May 1) and the entry liquidates for $1,500 (December 1). Upon liquidation, the importer will be billed for $300 plus interest. The interest accrues in two segments: (1) on the additional deposit ($200), from the date deposit was required (January 1) to the date of the additional deposit (May 1); and (2) on the remaining underpayment ($300), from the date deposit was required (January 1), to the date of liquidation (December 1).

(3) If an entry or reconciliation is determined upon liquidation or reliquidation to involve both an excess deposit and an excess refund made prior to liquidation or reliquidation, interest in each case will be computed separately and the resulting amounts shall be netted for purposes of determining the final amount of interest to be reflected in the underpaid amount. An example follows:

Example:

Excess pre-liquidation deposit and excess pre-liquidation refund

Importer owes $200 plus or minus net interest as follows:

The importer makes a $1,000 initial deposit on the required date (January 1) and receives a pre-liquidation refund of $300 (May 1) and the entry liquidates for $900 (December 1). Upon liquidation, the importer will be billed for $200 plus or minus net interest. The interest accrues in two segments: (1) Interest accrues in favor of the importer on the initial overpayment ($100) from the date of deposit (January 1) to the date of the refund (May 1); and (2) interest accrues in favor of the Government on the refund overpayment ($200) from the date of the refund (May 1) to the date of liquidation (December 1).

(4) If the additional deposit or any portion thereof is determined upon liquidation or reliquidation of the applicable entry or reconciliation to constitute a payment in excess of the amount initially required to be deposited, the excess deposit will be treated as a refundable amount on which interest also may be payable (see § 24.36).

(C) If a depository bank notifies CBP by a debit voucher that a CBP account is being debited due to a dishonored check or dishonored Automated Clearinghouse (ACH) transaction, interest will accrue on the debited amount from the date of the debit voucher to either the date of payment of the debt represented by the debit voucher or the date of issuance of a bill for payment, whichever date is earlier.

(1) The percentage rate of interest to be charged on such bills will be based upon the quarterly rate(s) established under sections 6621 and 6622 of the Internal Revenue Code of 1954 (26 U.S.C. 6621, 6622). The current rate of interest will appear on the CBP bill and may be obtained from the IRS or the CBP's Revenue Division, Office of Administration. For the convenience of the importing public and CBP personnel, CBP publishes the current interest rate(s) in the Customs Bulletin and Decisions and Federal Register on a quarterly basis.

(2) The percentage rate of interest applied to an overdue bill will be adjusted as necessary to reflect any change in the annual rate of interest.

(3) Interest on overdue bills will be assessed on the delinquent principal amount by 30-day periods. No interest charge will be assessed for the 30-day period in which the payment is actually received at the “Send Payment To” location designated on the bill.

(4) In the case of any late payment, the payment received will first be applied to the interest charge on the delinquent principal amount and then to payment of the delinquent principal amount.

(5) The date to be used in crediting the payment is the date on which the payment is received by CBP.

(1) Principal. The principal will be notified at the time of the initial billing, and every 30 days after the due date until the bill is paid or otherwise closed. Where the notification is returned to CBP due to an incorrect mailing address, the bill may be stopped. The following elements will normally appear on the bill:

(2) Surety.
