Zentria Flow vs SimplyDuty
SimplyDuty gives you the MFN rate in seconds. Zentria Flow gives you the full landed cost — every duty layer, every port fee, FTA scoring, and a CFO-ready breakdown that turns a rate lookup into a defensible procurement decision.
SimplyDuty
Best for quick, affordable MFN rate lookups. Low price point, simple interface, works for most non-China origins. Does not model Section 301 or the forced-labor tariff, does not calculate MPF/HMF, does not classify HS codes, and has no FTA or anti-dumping functionality.
Zentria Flow
Best for importers who need total landed cost accuracy: MFN + Section 301 + forced-labor stacking, AI-powered HS classification, FTA eligibility scoring, anti-dumping watch, document AI, and CFO-ready PDF outputs. Free tier: 3 calculations a day with no account, 10 with a free one.

The Critical Difference
A rate estimate vs a total landed cost
SimplyDuty returns the MFN base rate. That's useful for a quick sanity check, but it's not the number that appears on your customs entry. For US ocean imports, every shipment also carries MPF (up to 0.3464%) and HMF (0.125%). For China-origin goods, the effective rate stacks Section 301 (7.5–25%) and the 12.5% forced-labor tariff on top of the base.
Zentria Flow computes the full stack — all layers, all fees — and presents the breakdown in a format your CFO can review and sign off on. The goal isn't just a number. It's a defensible procurement decision.
Frequently asked questions
What does Zentria Flow do that SimplyDuty doesn't?
SimplyDuty is a fast, affordable MFN rate reference tool. Zentria Flow computes the full landed cost: MFN base duty, Section 301 surcharge (for China-origin goods), July 2026 forced-labor tariff, MPF, HMF, freight, insurance, and destination VAT/GST — in a single calculation. Zentria Flow also classifies HS codes with AI (SimplyDuty requires you to know your HS code), provides FTA rules-of-origin scoring, anti-dumping order monitoring, document AI extraction from commercial invoices and bills of lading, CFO-ready PDF exports, and an 8-course compliance Academy.
Is SimplyDuty accurate for US imports?
SimplyDuty is accurate for the MFN base rate, but for US imports — especially from China — the MFN rate is only the first of three duty layers. It does not add Section 301 surcharges or the July 2026 forced-labor tariff. It also does not calculate MPF (Merchandise Processing Fee) or HMF (Harbor Maintenance Fee), which together add 0.35–0.55% to the shipment value on most US ocean imports.
Does SimplyDuty classify HS codes automatically?
No — SimplyDuty requires you to enter the HS code yourself. Zentria Flow includes an AI-powered HS code classifier that suggests the code from a product description, returns a confidence score, and flags ambiguous classifications (below 85% confidence) for human review. It also suggests up to 3 alternative HS codes with lower duty rates.
SimplyDuty is cheaper. When should I pay more for Zentria Flow?
SimplyDuty Pro at $17/month makes sense for importers who have simple shipments from non-China origins and already know their HS codes. Zentria Flow at $49/month is the right choice if you: import from China (the three-layer duty stack changes the economics significantly), need FTA eligibility scoring to save duty, want anti-dumping order alerts, need document AI to speed up invoice processing, or need defensible CFO-ready outputs rather than a rate estimate.
