What to look out for if you receive a CBP Bill Form and how to stay on top of any pending CBP bills using ACE.
Receiving Bill Forms
It’s important to be able to identity and take prompt action on any CBP Bill Forms that your company may receive. Here are a few key things to note:
Why Bill Forms are Sent
CBP may send such a bill for a variety of reasons, including but not limited to: entries liquidated with duty increase, because of PSC or an entry reviewed by customs with an issue other than PSC, a disagreement with HTS or FTA application, etc.
Bills Sent via USPS
These bills are sent by CBP via U.S. Postal Service (USPS) and payment is time-sensitive so it’s important to ensure that the internal teams who receive and sort your company mail be made aware of the importance of this type of CBP correspondence.

Due Dates
Once a bill is received, aside from reviewing all details and noting the bill number, transaction IDs, and amounts due, it is crucial to check the due date of the bill as interest can easily accrue. Make your payments with enough time prior to the “Amount Due After” date to prevent interest from accumulating on your bill — interest accrued is based on the date when CBP receives payment, not the date your payment is sent.
Making a Physical Payment
Generally, it’s best to allow 7 to 10 days for payments sent via USPS regular mail and 2 to 3 days if sent by USPS overnight express. See note above regarding interest on late payments.
It is important that payments be sent to the correct address. The address for the U.S. Bank lockbox as reflected on most bills. Reach out to the Revenue Division at 317-614-4811 or billinginquiry@cbp.dhs.gov if you have any questions regarding the CBP address.
If not sent via check, bills may be paid via wire transfer.
