Smart tariff classification for your business.

No. Claz is an assistive tool that speeds up and documents classification; the final decision and legal responsibility stay with the professional. Think of it as a copilot with an audit trail.

Claz uses the same class of AI as ChatGPT, but specialized: it's grounded in millions of customs documents and the official nomenclature, and every answer descends the tariff tree with citations you can audit. A general chatbot isn't built for this. Ask one to classify white chocolate and it will call it 'chocolate', when for customs it's sugar confectionery. Claz also runs many classifications in parallel and puts your whole team on one subscription. Use it alongside other tools if you like, and, as with any AI, alongside a licensed customs professional.

You could, but it's rarely worth it. It means tuning models, ingesting and continuously updating each country's tariff schedule, and running the infrastructure, all of which costs far more than a subscription. We've already done that work and keep it current, so you can start classifying today. We're happy to help you onboard.

The schedules are public, but classifying against them is the hard part. Claz researches your product, walks the nomenclature to the right code, and gives you the reasoning and citations, turning hours of manual lookup into seconds. The data is free; the expertise and speed are what Claz adds.

Every result comes with a confidence score and its reasoning. If confidence is low or it doesn't match, you can reclassify by answering open questions, review the proposed alternatives, or refine the description.

Generally yes, but it's good practice to have a person review them, since customs authorities are strict about declarations. The engine is rarely wrong, but when a description is ambiguous it may assume details (for example, 'apple' as fresh apples). Claz always shows the assumptions it made, along with its reasoning and citations, so you can check them.

Yes. Each classification includes the reasoning, the General Rules applied, and citations to the nomenclature, so you can support and audit the chosen heading.

From each country's official sources: ARCA (Argentina), SENIAT (Venezuela), USITC/CBP (US), CBSA (Canada) and TARIC (EU), plus the Harmonized System nomenclature.

We re-ingest the official sources periodically and whenever the nomenclature changes, so you always classify against the current version.

Today we cover Argentina, Venezuela, the United States, Canada and the European Union, and we add new jurisdictions continuously.

Yes. Your products and documents are private to your organization, with tenant isolation, and are never shared with other customers.
