TRACEABLE REFERENCES

Official sources & data status

We link directly to the authorities for each market. A reviewed URL does not mean we have verified your product's import classification or synced customs duty rates.

What gets updated?

Official source links: the reference register was prepared on 2026-10-23. A reference-check date is not a tariff publication date. Exchange rates: the calculator requests a Frankfurter observation and displays the date returned by that service. Duty, tax and freight: the numeric values are entered by you, not automatically retrieved from these sources.

Country-by-country source register

Additional references

Frankfurter — date-stamped reference currency conversion; not necessarily a legally prescribed customs rate.

Amazon Revenue Calculator — sales and fulfillment cost context. Inbound placement or prep inputs must be verified in relevant seller documentation and shipment plans.

Freightos freight guide — market background; not used as a live quote feed. We do not generate FBA shipping rates from an ocean container index.

Important exclusions

No licensed national tariff database, no automatic HS classification, no real-time carrier quote or Amazon account access is included in this version. Destination tax models are simplified and may omit product-specific, transaction-specific or origin-specific obligations. Consult calculation methodology.
