CBP scrutinizes tariff engineering claims through risk targeting and Focused Assessments. Triggers: pattern of reclassification on existing SKUs, sudden classification shifts coinciding with rate changes, missing supporting documentation. Defense strategies: thorough documentation, binding rulings, transparent compliance posture.
This guide covers Tariff Engineering and CBP Scrutiny. Tariff engineering is the legal modification of products to fit HTS subheadings with lower duty rates.
For SMB importers, the practical implementation depends on volume, sector, and specific operational structure.
CBP risk targeting indicators
Pattern of PSCs reclassifying products. Reclassifications timed with rate changes (e.g., shifting out of Section 301 list at the same time the list rate increased).
Audit triggers
Industry-wide focused assessments. Specific importer risk profiles. Whistleblower complaints.
Defense strategies
Thorough documentation, binding rulings, transparent compliance posture, proactive engagement during audit.
Settlement options
Where audits identify issues, voluntary tender or prior disclosure can reduce penalty exposure significantly.
Frequently asked questions
When is this most relevant?
For SMB importers with active duty exposure or those evaluating duty mitigation options.
What documentation is required?
Varies by topic. Core: CBP Form 7501, supplier certificates, BOM analysis, manufacturing process documentation.
How long does this take to implement?
Simple cases 2-4 weeks; complex setups 8-16 weeks. Some moves require binding rulings adding 30-90 days.
What does this cost?
Project scope: $5,000-$25,000 for most engagements. Ongoing retainer for active operations.
How do I begin?
Book a 15-minute scoping call. We confirm fit and scope before any engagement.
Get started
