Purserhouse checks tariff refunds and demurrage invoices
A document-focused service for US importers that checks CBP 7501 forms for possible IEEPA refunds and demurrage invoices against carrier tariffs.
- For
- US importers of goods made in China
- Worth noticing
- The example separates a 9903.01.24 IEEPA duty from a 9903.88.03 Section 301 line, which it says is not an IEEPA duty.
Field notes
The public pages include single-line calculators and guides alongside a document-submission route for a full CBP 7501 or demurrage-and-detention invoice. The illustrated 7501 separates IEEPA lines from a Section 301 charge and flags liquidation status as unavailable on that form; the invoice example recalculates free time around an observed federal holiday. Purserhouse says results link to CBP tables or the carrier's tariff and that submitted files are deleted after seven days; the worked examples are identified as fictional.
