Common Reasons to Dispute Customs Fees (And Why You Have a Strong Case)

Disputes succeed on these grounds (Trade Ready: 5 common violation categories):

Incorrect Classification: Wrong HTS code (e.g., CJEU outdoor shelters case--6.5% duty drop from 9406 to other).
Undervaluation/Overcharge: Prove true value with invoices.
Broker Negligence: Recover fees if errors like missing ISF ($5k-10k CBP fines).
Penalties: Challenge improper fines (EU €3,700 for docs failure).
Post-Import Changes: Eligibility under FTAs (19 CFR Part 10).

Mini Case: CJEU ruled animal shelters as "prefabricated buildings" (lower duty), saving importers thousands annually on €600/unit imports.

Proving Undervaluation and Broker Errors

Docs Needed: Invoices, entry summaries (CBP 7501), HTS lookup, origin certs (19 CFR 10). For brokers: Contract showing negligence (Trek Leather case--employee liability).

Evidence Tips: Compare declared vs. actual value; photos of goods; supplier affidavits. Recovery: Demand refund letter + small claims if needed.
