Building the future of
global trade compliance
We help e-commerce businesses and importers navigate the complexity of international customs duties β with the accuracy and speed that modern commerce demands.
A problem experienced firsthand
In 2023, while running international product sourcing, DutyFlow founder Damien Flohic hit the same wall every importer eventually hits: calculating the true landed cost of goods from China was a nightmare. Base HTS rates were only the start β Section 301 surcharges, IEEPA layers, MPF and HMF fees, FTA eligibility β each variable buried in a different government portal, formatted differently, updated on different schedules.
The tools that existed were either outdated tariff classification consultants charging by the hour, or general-purpose LLMs that confidently made up duty rates. Neither was acceptable for building reliable pricing logic into a real e-commerce operation.
DutyFlow was built to solve that problem: a single deterministic API that ingests official government data daily and returns a fully-cited, itemized duty calculation in under 100ms. No guessing. No hallucinations. The kind of tool Damien wished had existed when he needed it.
What we stand for
Accuracy
Every duty rate is sourced directly from official government databases β USITC, USTR, CBP. Zero guessing, zero interpolation.
Transparency
Every calculated rate comes with source citations. You can trace every number back to the exact government document.
Speed
Sub-100ms API responses. Because compliance checks shouldn't slow down your checkout.
Reliability
99.9% uptime SLA. Tariff data updated within hours of any Federal Register publication.
