ABOUT ONTONEXA

Classification support you can inspect

Ontonexa helps cross-border teams move from messy product descriptions to a tariff path they can review. The product combines entity linking, structured product facts and official tariff references; it does not replace a customs ruling.

What we build

Our tools cover the connected workflow around classification: product-to-code lookup, country crosswalks, existing-code audits, import duty and landed-cost planning, origin screening, bulk catalog review and customs-document preparation.

How the logic is reviewed

  1. 1Official tariff releases are recorded with a dataset name and effective date.
  2. 2Product entities and multilingual terms are tested against a regression set.
  3. 3Candidate retrieval is checked for valid codes, useful alternatives and sensible abstention.
  4. 4Pages expose the source, release note and feedback path so mistakes can be corrected.
