HS Code Classification Accuracy Benchmark
Independent classification accuracy testing against the EU's EBTI (European Binding Tariff Information) database — the gold standard for HS code classification.
Methodology
Test Data
Products are sourced from the EU's EBTI (European Binding Tariff Information) database — legally binding classification decisions made by EU customs authorities. Each product includes an official product description, product image, and the correct HS code assigned by certified customs experts.
Classification Process
Each product is classified using Import8's multi-step AI classification pipeline: semantic keyword extraction, candidate HS heading search across 16,000+ tariff codes, and final classification with full commodity tree context and EBTI rules. The AI receives both product images and descriptions — identical to real-world API usage.
How we measured
Sample: 283 independent EBTI products drawn from the EU's European Binding Tariff Information database. Coverage: 54 of 97 HS chapters (43 chapters not yet tested — typically raw materials and chemicals with low EU import volume). Method: top-down General Rules of Interpretation (GRI), supplemented by TARIC chapter notes and hand-tuned EBTI rules. Last benchmark run: 19 March 2026.
Limitations
These benchmarks are run on Express-mode (autonomous, no human confirmation). Audit-mode results may differ. Edge cases (ambiguity between adjacent chapters) are excluded — see Audit-mode for those. We test against EBTI rulings; live customs decisions can vary. Duty rates are sourced from the EU TARIC database and are indicative only.
