US CBP Post-Entry Amendment &
Duty Recovery
Recover overpaid duties on US imports through Post-Entry Amendments and Protests. Our AI-powered platform analyses your ACE data, identifies HTS misclassifications, Section 301 exclusion opportunities, and builds CBP-ready correction packages.
Why US Imports Are Leaking Duty Dollars
The US customs environment is more complex than ever. Between Section 301 tariffs on Chinese goods, shifting HTS classifications, and the constant churn of trade policy under Trump 2.0, even experienced customs brokers struggle to keep up.
Most brokers are focused on clearance speed, not duty optimization. They use the HTS codes that worked last time, even if better classifications exist. They miss Section 301 exclusions because tracking USTR notices isn't their core business. And they certainly don't have time to reconcile your ACE data against what you should have paid.
The result? You're overpaying CBP, and the clock is ticking on your recovery window.
Common US Entry Errors We Find
HTS Misclassification
Wrong tariff heading can mean 25% Section 301 tariff vs. 0% under an FTA.
Missed Section 301 Exclusions
USTR has granted thousands of exclusions—but your broker has to know to claim them.
USMCA/FTA Origin Errors
Goods qualify for preferential treatment under USMCA or other FTAs, but documentation wasn't filed.
Valuation Overclaims
Transaction value includes non-dutiable costs, or first sale valuation wasn't used when available.
Trump 2.0: The Stakes Are Higher
With renewed focus on trade enforcement and potential new tariffs, CBP is auditing more aggressively. Errors that might have slipped through are now being caught—and penalties are steep.
Independent oversight isn't just about recovery anymore. It's about audit defense.
Our US CBP Audit & Recovery Process
We analyse your ACE data, identify recoverable overpayments, and build CBP-compliant correction packages—whether that's a Post-Summary Correction, Post-Entry Amendment, or formal Protest.
ACE Data Extraction
We securely pull your entry summaries (CF7501), commercial invoices, and supporting documentation directly from ACE or via your broker. API integration available for ongoing monitoring.
AI-Powered HTS & Tariff Analysis
Our platform cross-references every entry against:
- USITC Harmonized Tariff Schedule database
- USTR Section 301 exclusion lists (historical & current)
- FTA preference databases (USMCA, Korea, Australia, etc.)
- Antidumping/countervailing duty orders
Licensed Customs Broker Review
US-licensed customs specialists validate every flagged entry. We confirm the error, calculate the recoverable amount, and determine the correct filing mechanism (PSC, PEA, Protest, or Drawback).
CBP Filing Package
We prepare the complete correction package: amended CF7501, supporting documentation, tariff justification, and filing instructions. For Protests, we draft the legal argument.
Your package includes:
- Corrected entry summary
- HTS classification ruling support
- Section 301 exclusion documentation
- Recovery amount calculation
Continuous Monitoring
We monitor new entries in real-time, flagging errors before liquidation. Plus, we track USTR announcements so you never miss an exclusion opportunity or tariff change.
The Bottom Line
US importers typically recover 2–4% of their annual duty spend in the first year. For a company paying $5M in duties annually, that's $100K–$200K back in working capital.
And with Trump 2.0 enforcement ramping up, the audit protection alone is worth the investment.

US CBP Recovery Success Stories
Electronics Components Distributor
Technology Sector • $8M Annual Duty Spend
A US electronics distributor recovered $285,000 in Section 301 duty overpayments by identifying products that qualified for USTR exclusions their broker had missed. Our audit also found HTS classification opportunities that reduced ongoing duty rates by 8%.
"With Section 301 tariffs constantly changing and new exclusions being granted, it's impossible for any single broker to catch everything. We're finding recoverable errors in roughly 30% of the US entries we audit—and that's from well-regarded brokers who are doing their best in a chaotic trade environment."
Frequently Asked Questions about US CBP Recovery
How far back can we file Post-Entry Amendments with CBP?
Under 19 CFR 173, you have up to 314 days from the date of entry to file a Post-Entry Amendment (PEA) for most corrections. For duty refund claims, you may have up to 2 years under certain circumstances. For drawback claims, the window can extend to 5 years. Our team analyses your entry history to identify all corrections within the applicable timeframes.
Can you help with Section 301 tariff exclusions and refunds?
Yes. We monitor USTR exclusion lists and identify entries where your products may qualify for Section 301 exclusions—either retroactively or prospectively. If you've been paying Section 301 duties on excluded products, we build the refund claim. We also track the Trump 2.0 tariff landscape to help you plan ahead.
What data do I need to provide for a US customs audit?
We need access to your ACE portal data (entry summaries, CF7501s), commercial invoices, packing lists, and certificates of origin. If you have drawback claims, we'll also need export documentation. You can share data via secure upload, SFTP, or direct ACE API integration.
Do you handle both Post-Summary Corrections and Protests?
Yes. Post-Summary Corrections (PSCs) are used for administrative errors discovered within 314 days. Protests (19 CFR 174) are used when CBP disagrees with your claimed treatment or for errors discovered later. We determine the right mechanism based on timing, error type, and likelihood of success.
