CustomsShield stands between importers and the full weight of federal enforcement — filing classifications, contesting penalty notices, and steering shipments through HTS codes before they hit the dock.
Three engagements, in ascending order of complexity. Each one began as a crisis. Each one became a receipt.
Mid-market HVAC manufacturer, Ohio — 340 shipments annually
CBP issued CF-28 after flagging 18 months of entries. Broker had defaulted to general pump classification, triggering Section 301 List 3 exposure on every shipment.
Filed corrected protests under 19 U.S.C. § 1514. Secured retroactive exclusion under USTR Annex C. All 18 months of entries reliquidated at zero rate.
E-commerce electronics brand, California — $12M annual import value
Scaling cross-border operations triggered CBP scrutiny. 47 SKUs classified under List 4A. Compliance officer received CF-29 penalty notice with 30-day response window.
Engineered USTR exclusion strategy across 47 SKUs. Filed 23 separate exclusion petitions with technical specifications. 19 granted, 4 under appeal. Restructured COO documentation for remaining SKUs.
Tier-2 automotive supplier, Michigan — $47M annual import value
CBP Regulatory Audit Division initiated Focused Assessment covering 5 fiscal years. 3,200 entries under review. Potential fraud referral if willful misclassification found. Internal counsel engaged CustomsShield 11 days before first document production deadline.
Conducted internal audit before CBP review. Identified and self-disclosed 14 classification errors under Prior Disclosure program. Negotiated penalty reduction from $4.2M to $380,000. Implemented compliance program accepted by CBP as audit resolution.
Toggle between industries to see common misclassification patterns, assessed duty rates, and what corrected HTS codes actually recovered.
Section 301 List 3 & 4A exposure dominates. PCB assemblies, control modules, and IoT devices frequently misclassified under Chapter 84 vs 85.
