Product Classification
The right category, every time, continuesly. At catalog scale.
Product classification is the process of assigning each product to the right category in your internal taxonomy. Claro classifies products against your taxonomy automatically — with confidence scoring and provenance for every assignment. Low-confidence cases route to review. Claro supports industry standards like ETIM, ECLASS, and GS1, as well as custom internal taxonomies, and can build or repair taxonomies as the catalog grows. Used by Eventim for dynamic event categorization at scale, with 5x faster time to market on new categories.

The problem
Categorization at scale is unsustainable manually.
Thousands of decisions per day. Same product, categorized differently by different people on different days. Taxonomies that worked at launch don't fit as the catalog grows.
Taxonomy outgrown by the catalog
Inconsistent categorization across teams
How it works
From messy supplier data to ready-to-sell products
Claro classifies, validates, and writes back — and can build or repair the taxonomy itself when the catalog outgrows it.
Step 1
Understand your taxonomy
Claro ingests your existing taxonomy or builds one from your catalog if you don't have a usable one. ETIM, ECLASS, GS1, custom, or hybrid.
Step 2
Classify incoming records
Each product is classified using attribute signals, descriptions, source documents, and semantic similarity to already-classified products.
Step 3
Score and Validate
Every classification carries a confidence score. Validation runs against taxonomy rules — allowed categories per attribute, required attributes per category.
Step 4
Write back and repair
Classifications flow into PIM, search, merchandising, and downstream systems. When the taxonomy needs to change, migrations run with full audit history.
What you get
Consistent classification across the whole catalog.
Categorization decisions get made consistently across products, sessions, and team members. Industry standards (ETIM, ECLASS, GS1) are supported natively. When the catalog outgrows the taxonomy, Claro proposes the migration. When new categories emerge, dynamic taxonomy generation handles them. Eventim cut time-to-market on new event categories by 5x using this workflow.


Who is it for
Built for teams managing growing catalogs and partner-feed requirements.
Catalog, merchandising, search, and compliance teams at distributors, marketplaces, and platforms where classification accuracy affects discovery, partner compliance, or operational hierarchy.
100s of new product per quarter
Need ETIM, ECLASS, or GS1 compliance
Taxonomy struggling to keep up with the catalog
Need consistent classification across teams and time
Classification underpins discovery, merchandising, and compliance.
Wrong classification doesn't just hurt search. It cascades into every operational and commercial decision tied to product hierarchy. Claro classifies with confidence and validates against your taxonomy rules — and handles taxonomy migrations with audit history.
Automated, governed classification with confidence, validation, and taxonomy support built in.
