Frequently Asked Questions

We need the following 12 fields. These are present in the standard ES-003 Entry Summary Line Tariff Details report in Customs and Border Protection's ACE Reporting Portal:

Some tariffs, like the recently introduced Section 122 Temporary Import Surcharge, tend to have additional applicability conditions based on departure dates and mode of transport. Additionally, your actual duty calculation date can be different from your Entry Date if you made use of an In-bond Transportation move.

To allow us to improve the accuracy of the audit results by accounting for all these factors, we strongly recommend including the following optional fields:

Mode of Transportation Code
Exportation Date
Inbond Immediate Transportation Date

Finally, we also calculate how many of the erroneous entries could be fixed by filing a Post Summary Correction and how many might require Protests due to having liquidated already. To improve accuracy of these calculations you can also include the following 2 fields:

Liquidation Date
Liquidation Status

The audit runs over 115+ stacking rules across Section 122, Section 232, Section 301 and the now expired IEEPA tariffs. It highlights errors and entries where we suspect incorrect Chapter 99 tariff usage as well as duty overpayment or underpayment that might have occurred as a result of these errors. We also flag a handful of origin countries and HTS codes that, in our experience, are unusual for most importers.
