You overpaid. CBP knows. Most importers don't. Caspian audits every customs entry you've filed, finds the recoverable duty, and files for refund before the deadlines close.
A trade audit is a line-by-line review of every customs entry your company has filed — checking classification, valuation, country of origin, and applicable tariff treatments against what you actually paid to CBP. The goal is to find the duties you overpaid and the refund opportunities you missed. Most importers think of audits as something CBP does to them — a Focused Assessment, a CF-28, a knock on the door. The proactive, importer-led version flips that. You find the errors first, recover what you're owed, and tighten your compliance posture before CBP ever comes asking.
Caspian runs that review continuously, across every entry in your ACE history, in days instead of months.
ACE is the system every U.S. importer files through - and the system most importers never actually look at. It holds five-plus years of your customs entry history, line by line: every HTS code, every duty paid, every tariff applied. Caspian connects directly to your ACE Portal and turns that raw data into something readable. You see your full duty exposure, where overpayments cluster, which entries are still inside the recovery window, and which suppliers or HTS codes are quietly costing you the most. No PDFs. No broker handoffs. No waiting on quarterly reports.


A review of your shipping data before you file with CBP. Our team validates classification, valuation, quantities, and country of origin so the entry goes in correctly the first time — catching errors while they're still cheap to fix and before they compound across thousands of future entries.

A look back at entries you've already filed, typically four to five years deep. Surfaces overpayments, missed FTA preferences, and unclaimed Section 301/232 exclusions — then files PSCs or protests on your behalf to recover the duty before CBP's deadlines close on you.
In customs work, timing decides whether a recovery opportunity is alive or already gone. Once an entry liquidates, your window to correct it shrinks fast — and once it closes, the duty is permanently yours, mistake or not. The deadlines below govern every recovery mechanism CBP allows. A trade audit only creates value if it runs against entries that are still actionable, which is why Caspian prioritizes them by time-to-deadline, not size of finding.
A trade audit is a line-by-line review of every customs entry your company has filed to find duty overpayments, misclassifications, and refund opportunities you've missed. The process traditionally required a customs attorney, weeks of manual work, and access to data scattered across brokers, ERPs, and CBP systems. Caspian's Trade Audit ingests all of it automatically and surfaces every recoverable dollar in your customs history.
Your customs broker files entries. Caspian audits them. Those are different jobs. Brokers are paid to clear shipments through customs as fast as possible, they're not paid to go back and check whether you overpaid, and most don't. Caspian's Trade Audit looks at every entry your broker has ever filed and flags the ones that left money on the table.
Three things, mostly: duties you overpaid because of HTS misclassification, valuation errors that inflated your duty owed, and refund eligibility you never claimed (drawback, PSCs, protest opportunities). The audit also flags liquidation deadlines you're about to miss once an entry liquidates without correction, the money is gone. Most clients recover more in month one than they spend on Caspian in a year.
Five years for drawback eligibility, 314 days for PSCs, 180 days post-liquidation for protests. Trade Audit scans your full customs history and maps every entry to the recovery mechanism that still applies. Entries past their statutory window get flagged so you know what was missed and why. Useful context, even when the money's gone.
Whatever you have. Caspian connects to 80+ systems, including ERPs, customs brokers, freight forwarders, and inventory platforms, and pulls the data automatically. No reformatting, no CSV exports, no IT tickets. The point of Trade Audit is to remove the data-gathering step that kills most recovery projects before they start.
Caspian's audit runs continuously the moment your data is connected, so recovery opportunities surface as your data flows in. Traditional trade audits work the opposite way. A consultant pulls your entries, reconciles them against your ERP by hand, and writes a memo at the end. Caspian replaces the project-based model with a live one.
Yes. Trade Audit is the entry point to the platform: you connect your data, we run the analysis, you see what you're owed. No retainer, no commitment, no sales call required to get the number. If there's nothing to recover, you've lost nothing. If there is, you decide what to do next.
You decide which recovery path to take, and Caspian executes it. Misclassifications and valuation errors get corrected through Post-Summary Corrections. Adverse liquidation decisions get challenged through Protests. Duties paid on goods later exported get recovered through Duty Drawback. Trade Audit is the diagnostic. The filing mechanisms are built in. Same platform, same licensed brokers, no handoff.
