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 IEEPA tariffs, 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 + IEEPA stacking, AI-powered HS classification, FTA eligibility scoring, anti-dumping watch, document AI, and CFO-ready PDF outputs. Free tier starts at 3 calculations/day with no account.

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 April 2025 IEEPA reciprocal tariffs 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), April 2025 IEEPA reciprocal 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 April 2025 IEEPA reciprocal 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.
