Inverted tariff occurs when imported inputs face higher duty rates than the finished good produced from them. FTZ activation lets the manufacturer pay the finished-good rate instead of the input rate, capturing the difference as duty savings. Common in pharma, electronics, machinery, chemicals.
This guide covers FTZ Inverted Tariff Strategy. A Foreign Trade Zone is a U.S. zone where imported goods can be admitted, processed, and re-exported without paying customs duty.
For SMB importers, the practical implementation depends on volume, sector, and operational structure.
When inverted tariff applies
When finished-good rate < input rate. Most common in pharma (5% finished, 10-15% inputs), electronics (5% finished, 7.5-25% Section 301 inputs), machinery (2-5% finished, higher input rates).
How FTZ enables capture
In FTZ, no duty paid on input admission. Manufacturer produces finished good. Consumption entry pays duty at finished-good rate.
Calculation example
Pharma manufacturer with $50M imported APIs at 12% rate. Finished drug exits FTZ at 5% rate. Annual savings: $50M × (12% – 5%) = $3.5M.
When it does NOT work
When finished-good rate > input rate, or when Section 232 applies to specific inputs (Section 232 generally locks at admission for PF status).
Frequently asked questions
When does this apply?
For SMB importers with active duty exposure or those evaluating mitigation options.
What documentation is required?
Standard CBP forms plus topic-specific supporting records. We review documentation as part of typical engagements.
What is the timeline?
Simple cases 2-4 weeks; complex setups 8-16 weeks.
What does this cost?
Project work: $5,000-$25,000 depending on complexity. Ongoing retainer for active operations.
How do I begin?
