Check a customs entry you’ve already filed.

Drop your ACE entry-summary export (best) or a filed 7501 PDF. Entry Check answers four questions about it:

1Does your entry comply with the tariff schedule? We recompute the duty from the codes on your form — line by line, at the entry’s own date and origin. A rate can move after you file, a Chapter 99 code can be missed, or an exemption claimed that the general column does not carry; wherever what you filed differs, you see it and why.

2Are you paying duty where others claim an exemption? On your exact tariff line, we show what share of the national trade entered duty-free that month. When other importers take an exclusion or trade-program route and you paid full duty, that gap is the question to put to your broker.

3Where does your invoice value sit? Your declared value per kilo, against the trade for that same product. A value far from the crowd — high or low — is the first thing a customs officer looks at.

4Are your IEEPA duties reconciled in ACE? With your ACE refund report (REV-603), we match what CBP has already refunded — reciprocal and IEEPA duty it later struck down — entry by entry, so you know what is settled and what is still open.

Who runs this. Entry Check is an instrument of Trimtabist, built and run by Mrigank Singh, who also runs an India–US freight forwarder (Intoglo) — an economic interest stated here, with the disclosure and process that go with it. It does not file with CBP and takes no fee on any refund.

What happens to what you upload. Your report lives at one private link that expires after 30 days unless you sign in to keep it. A copy of each upload is kept in a private archive on this server, never web-served, to improve the checker; it is not sold, published, or used to build anything that identifies an importer. ACE exports are parsed on this server only; a 7501 PDF is read by Google’s Gemini model, so that file is sent to Google. If either is unacceptable, do not upload.

Informational only — not legal or customs advice, and not a determination of what anyone owes or is owed. Only U.S. Customs and Border Protection determines the correct duty. Review every item with a licensed customs broker before acting.
