Tool Comparison · 2026
Zentria Flow vs DutyDecoder
Both tools calculate import duties. The gap is what happens when you import from China in 2026 — DutyDecoder shows you the MFN base rate. Zentria Flow shows you the real number: MFN + Section 301 + forced-labor tariff, stacked and documented for your CFO.
DutyDecoder
Best for basic MFN duty lookups across ~50 countries. Clean interface and reasonable coverage for non-US tariff regimes. Does not model Section 301 surcharges, forced-labor tariffs, or provide FTA scoring — making it inaccurate for China imports under the current US tariff regime.
Zentria Flow
Best for importers who need the full picture for 70+ countries: three-layer duty stack (MFN + Section 301 + forced-labor tariff), FTA eligibility scoring, live anti-dumping watch, document AI, CFO-ready PDF outputs, and a compliance Academy. Free tier covers most basic needs.

The Critical Difference
For China imports, the MFN rate is the wrong starting point
DutyDecoder is built around the MFN rate. For China-origin imports that is only the first layer. The effective duty rate for China-origin imports is a three-layer stack: MFN base + Section 301 list rate (7.5–25%) + the forced-labor tariff (12.5% for China). A tool that skips layers two and three is showing you a number that is usually 20–40 percentage points too low, and more for chips, EVs and batteries.
Zentria Flow models all three layers, documents the stacking logic for CFO review, and flags every change to tariff rates and exemptions as it happens. The difference between a single rate lookup and a defensible procurement decision.
Frequently asked questions
What does Zentria Flow do that DutyDecoder doesn't?
The most critical gap is tariff coverage for US imports from China. DutyDecoder shows only the MFN base rate. Zentria Flow computes the full three-layer stack — MFN base rate, Section 301 surcharge (7.5–25%), and the forced-labor Section 301 tariff — in a single calculation. For a product on Section 301 List 3 importing from China, DutyDecoder may show 7.5% where the real rate is over 100% when all three layers are stacked. Zentria Flow also covers 70+ destination countries (DutyDecoder ~50), includes an FTA rules-of-origin engine, anti-dumping monitoring, document AI, and CFO-ready PDF exports.
Is DutyDecoder accurate for China imports in 2026?
No — DutyDecoder does not model Section 301 tariffs or the forced-labor Section 301 tariff. For China-origin imports, showing only the MFN rate can understate the actual effective duty rate by 50–150 percentage points. Any landed-cost calculation for China imports must account for all three layers of the current US tariff regime.
Which tool covers more countries?
Zentria Flow covers 70+ origin countries and 50+ destination economies with full duty stacks. DutyDecoder covers approximately 50 destination countries with basic MFN rate data. Both include VAT/GST for covered destinations, but only Zentria Flow models the US-specific Section 301 and forced-labor tariffs.
Does Zentria Flow export reports for finance teams?
Yes. Zentria Flow generates CFO-ready PDF exports with a full duty stack breakdown, FX exposure summary, FTA eligibility verdict, and anti-dumping risk memo in board-presentation format. DutyDecoder exports data as CSV only — no narrative context for finance stakeholders.
