Frequently asked questions

At a glance

What free trade tools does ExportSonar include?

The core set covers the whole landed-cost chain: a US tariff calculator with stacked Chapter 99 layers, an FTA eligibility checker, an HS browser spanning all 96 chapters and 23,193 HTS lines, and a CBP CROSS ruling library of 2,350 precedents. Everything runs without an account; paid tiers add watchlists, monitoring alerts and bulk exports.

Do I need an account to use the tariff calculator?

No. The calculator and every lookup tool work anonymously — enter an HTS code, origin country and shipment value and the estimate renders instantly. An account is only required to save watchlists or receive rate-change alerts, and the metered API debits the USD 0.06 list rate per successful call from prepaid credits ($0.05 per call via the $10 credit pack, about 17% off).

How does the FTA eligibility checker work?

It decodes the special rate column program symbols attached to each HTS line — covering all 14 US free-trade agreements, KORUS, USMCA, Australia and Chile among them — for any code and country-of-origin pair you pick. Agreement dates in the underlying dataset were audited line-by-line against USTR and CBP primary sources, with each record carrying its own source URL.

Which tool should I start with for landed-cost planning?

Start at the HS browser to fix the ten-digit line, then open the calculator on that line: it applies the Column 1 general rate and stacks matching Chapter 99 measures automatically. If preferential treatment might apply, run the FTA checker next — comparing the MFN and program rates is usually where the margin hides.
