Classify any product under the HTSUS.
Free. Instantly.

Yes. You can classify any product under the HTSUS for free without creating an account. You get the 10-digit HTS code, applicable duty rates, and a summary of the GRI reasoning. Create a free account to save your results, build a persistent product master, and export full Classification Support Packages as PDF or Word documents.

Two things. First, determinism: Kanon's classification engine runs at temperature 0 against a pinned, versioned HTSUS corpus. The same product attributes always produce the same HTS code — regardless of how the question is phrased or when it's asked. General-purpose AI produces different answers to the same question depending on prompt wording.

Second, documentation: Kanon records every GRI decision point in an immutable Classification Support Package. That document is what CBP expects to see when they audit a classification. ChatGPT cannot produce a document that holds up in a CBP audit. Kanon can.

Yes — Kanon is built for customs brokers as well as importers. Create a free account, upload a commercial invoice, and Kanon extracts product data and runs classification for every line item. Each classification creates a persistent product record for that importer client. Classification work that was previously repeated with every invoice becomes a one-time investment per product. On the Pro tier, broker and importer accounts can be connected on a shared product master so both parties work from the same live record.

The General Rules of Interpretation (GRI) are the six legally mandated rules that govern how every product imported into the United States is classified under the HTSUS. GRI 1 applies first — classification by heading text and chapter/section notes. If that doesn't uniquely resolve the heading, GRI 2 through GRI 6 apply in sequence. Kanon traverses all six rules in this exact order — the same sequence CBP uses when it audits a classification. CBP expects importers to be able to explain which GRI rules applied to their classification and why. Kanon records that explanation automatically.

A Classification Support Package is the formal legal documentation of why a product was assigned a specific HTS code. It captures the GRI path taken, every provision evaluated with its pass/fail outcome, the HTSUS corpus version used, the product attributes at classification time, applicable duty rates, USTR exclusion status, and the confidence level. U.S. importers provide this document to CBP when a classification is audited or challenged. Kanon produces it automatically at the moment of classification and stores it as an immutable record.

Every Kanon classification is pinned to the exact HTSUS corpus version that was active at classification time. When the USITC publishes a new HTSUS edition, Kanon versions it. Your existing classification records remain valid against the corpus they were made against. On the Pro tier, Kanon sends corpus change alerts when an HTSUS update affects a provision that applies to your classified products — so you know which records may need reclassification before your next shipment, not after.
