Tool Comparison · 2026

Zentria Flow vs InstaDuty

Both tools calculate import duties. The difference is what happens after the base rate — Section 301 stacking, FTA scoring, anti-dumping watch, document extraction, and compliance training that turns a number into a defensible CFO decision.

InstaDuty

Best for quick MFN rate lookups. Clean UI, fast onboarding. No FTA engine, no Section 301 stacking, no anti-dumping monitoring, no compliance training. Good for occasional importers who just need a ballpark duty rate.

Zentria Flow

Best for importers who need the full picture: three-layer duty stack (MFN + 301 + reciprocal tariff), FTA eligibility scoring, live anti-dumping watch, document AI, CFO-ready outputs, and a compliance Academy. Free tier covers most basic needs.

The Critical Difference

April 2025 changed what "correct" means for duty calculation

After Liberation Day, the effective duty rate for most China-origin imports is no longer just the MFN rate. It's a three-layer stack: MFN base + Section 301 list rate (7.5–25%) + IEEPA reciprocal tariff. A tool that only shows you the MFN rate is showing you the wrong number.

Zentria Flow models all three layers per shipment, documents the computation for CFO review, and flags snap-back risk when the 90-day pause on reciprocal rates expires. That's the difference between a number and a defensible procurement decision.

Frequently asked questions

What does Zentria Flow do that InstaDuty doesn't?

Zentria Flow computes the full three-layer duty stack — MFN base rate, Section 301 surcharge, and April 2025 IEEPA reciprocal tariff — in a single calculation. It also includes FTA rules-of-origin scoring (USMCA, KORUS, EAEU), live anti-dumping order monitoring, document AI extraction from commercial invoices and bills of lading, CFO-ready PDF exports, and an 8-course trade compliance Academy with a verified certificate. InstaDuty is a cleaner duty-rate lookup tool but does not offer FTA engine, anti-dumping monitoring, document extraction, or compliance training.

Is Zentria Flow free to use?

Yes. Zentria Flow's free tier provides 3 full landed-cost calculations per day — including customs duty, Section 301 surcharge, MPF, HMF, freight, and VAT — with no account or credit card required. Three Academy courses are also free with no signup wall.

Which tool is better for China imports?

Zentria Flow is more accurate for China imports because it models all three applicable duty layers: the MFN base rate, the Section 301 list rate (7.5–25% depending on product category), and the April 2025 IEEPA reciprocal tariff. It also monitors live anti-dumping and countervailing duty orders against Chinese exporters, which can add significant unexpected costs.

Does Zentria Flow work for FTA qualifying imports?

Yes. Zentria Flow covers 55+ FTA agreements including USMCA, KORUS, EU Customs Union, CPTPP, and EAEU. It estimates the potential duty reduction for each shipment and tells you which origin documentation (Form A, EUR.1, USMCA certificate) to prepare. Note: final eligibility requires your customs broker or trade counsel to validate the specific rules of origin for your HS code and supply chain.
