Caspian Platform

Trade compliance software that finds and recovers your duty.

Caspian connects to ACE, audits every entry against 100+ rules, and files the recovery: post summary corrections, protests, duty drawback and IEEPA refunds. A licensed customs broker signs off before anything reaches CBP.

One platform

Four jobs. Every duty dollar accounted for.

Audit the entries your broker files, recover what you overpaid, and catch every deadline before it passes. Each job runs on the same data, pulled straight from ACE.

01 · Audit

Customs audit of every entry.

Before your broker files, Caspian checks the entry. After it files, Caspian checks again while the post summary correction window is still open. Every rule returns pass, fail or skipped, and every failure lands in a review queue with the filed value, the calculated value and the difference.

Proactive trade audit →

02 · Drawback

Duty drawback software, filed by licensed brokers.

Choose the accounting method, set date ranges, match thresholds and substitution tolerance, include IEEPA duties, and run the match. For manufacturing claims, the CPA builder ranks every trace from serial number down to 4-digit HTS. A licensed broker transmits the claim and you recover up to 99% of the duty.

03 · IEEPA refunds

IEEPA tariff refunds, found and filed.

Caspian finds every entry that paid IEEPA duty, files the CAPE declaration or the protest, and tracks each refund as CBP reports it back through ACE.

04 · Corrections

PSCs and protests before the window closes.

Every correctable entry carries a clock. Caspian files post summary corrections before liquidation and protests within 180 days after it, so a recoverable dollar never ages out.

The data layer

ACE reports and 80+ integrations, synced automatically.

Caspian pulls your entry data straight from CBP's ACE system and joins it to your ERP, 3PL and broker feeds. Every entry is checked against one product catalog with the HTS code, origin and value for each SKU, so nobody on your team exports or reformats a spreadsheet.

Frequently Asked Questions

What is trade compliance software?

Trade compliance software checks your import entries for errors, tracks the deadlines that come with them, and files the corrections and refunds with CBP. Caspian pairs that software with licensed customs brokers who review and sign every filing.

What is duty drawback software?

Drawback software matches your exports, or goods you destroyed, to the imports they came from and builds the claim. Caspian recovers up to 99% of the duties, taxes and fees paid on those imports, and its brokers file the claim in ACE. Read the duty drawback guide.

Can Caspian file a post summary correction?

Yes. Caspian finds the error, prepares the correction and files it before the entry liquidates, with a licensed customs broker reviewing each one. Liquidated entries go through a protest, which has 180 days.

How do IEEPA tariff refunds work?

Caspian finds every entry that paid IEEPA duty, files the CAPE declaration or a protest, and tracks each refund as CBP reports it back through ACE. See IEEPA tariff refunds.

Does Caspian replace my customs broker?

Your broker keeps filing your entries. Caspian audits those entries and files the recovery work: post summary corrections, protests, drawback claims and IEEPA refunds.

What does Caspian cost?

Recovery work is success-based. We earn a share of what we get back for you, so finding out what you are owed costs nothing. Advisory and platform engagements are subscription-based, scoped to the work.
