TariffSync
U.S. Import Tariff Lookup API

The brief
A problem worth
building around.
Import duty research requires connecting product classifications, country-specific rules and supplementary duties. TariffSync explores how those lookups can fit into an API workflow instead of being repeated manually.
Our approach
The implementation combines rule-based product matching and keyword search with tariff lookups, caching and data synchronization. API key authentication, usage limits and audit logging support the surrounding developer workflow.
