Help — what telonio can do
A quick overview of the features. Most tools are used from a specific code — expand the catalogue tree, open a code and use the buttons on top.
Combined Nomenclature catalogue
Browse the whole EU nomenclature as a tree — section → chapter → code — with descriptions and lazy expansion.
Search
Search by code or description. Tolerant of declension and diacritics. No match? Try AI classification.
AI goods classification
Describe the goods in plain words and the AI suggests matching CN codes. In Application → “Classify goods” (after login).
Duty & VAT calculator
On a specific code enter origin, destination and customs value — it computes duty, VAT and the total landed cost. Button on the code detail.
Import scenario
Build a route origin → entry into the EU → destination and see the measures, duties, VAT and required documents that apply along it.
Country comparison
Put two countries' national layer side by side — national codes, VAT, measures and notes.
National layers
On a code detail switch the national layer (EU · EE · PL · SE …) to see that country's VAT, codes and measures. VAT is there for all 27 EU states.
Carbon border adjustment (CBAM)
Codes covered by the carbon border adjustment mechanism carry a badge on their detail page. The scope maintains itself and moves with the rules, so nobody has to check it by hand.
When the reduced VAT rate applies
The national layer can expand to show the conditions under which the reduced rate applies to that code. What decides is the actual use of the goods, not the classification alone.
AI assistant
Ask about a specific code in plain language; the assistant answers only from telonio's curated content (after login).
Legal references explained
Every citation of a regulation or act in the tables carries an orange ✨ button. Click it and the AI explains which act it is and what it requires, with a link to the official wording.
Print / PDF
Print or save the calculator, code detail or scenario as a PDF in one click — a reference for the customs file or the client.
Languages
Switch the interface and content between CS · EN · DE, top right.
Pro subscription
Licensed countries' national data and the AI features are on a paid plan. Status and requests in Application → Subscription.
Why telonio
A telonium was a customs house — the booth on the road or in the harbour where duty was assessed. The word is Latin, borrowed from the Greek τελώνιον; in the Vulgate, Matthew sits „in telonio“.
What grew out of it matters more. Czech clo, German Zoll, English toll and Dutch tol all descend from that same root, Czech by way of Old High German zol. One word, from which each country made its own.
That is what this tool does: it looks for the common ground beneath 27 national layers. Telonio is the customs house; the declarant is the one who walks into it.
