A Deterministic Agentic Workflow for HS Tariff Classification: Multi-Dimensional Rule Reasoning with Interpretable Decisions

Dongjiang Zhuang, Jing Cao, Junhe Wu, Kai Chen, Qu Zhou, Yu Zhang, Zheng Huang

A deterministic six-stage agentic workflow for HS tariff classification reaches 64.2% top-1 accuracy at six digits on HSCodeComp and flags possible inconsistencies in some ground-truth labels.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Evaluated on HSCodeComp at the six-digit level, the workflow reaches 75.0% top-1 and 91.5% top-3 at four digits, and 64.2% top-1 and 78.3% top-3 at six digits with Qwen3.6-plus; an open-weight Qwen3.6-27B-FP8 backbone achieves 84.2% four-digit and 77.4% six-digit top-1 agreement.

C2weakest assumption

That a fixed six-stage decomposition of multi-dimensional HS rule reasoning, supported by offline knowledge engineering, will correctly resolve all priority conflicts among material, function, essential character, and part-versus-whole axes without missing interactions that require dynamic reordering.

C3one line summary

A deterministic six-stage agentic workflow for HS tariff classification reaches 64.2% top-1 accuracy at six digits on HSCodeComp and flags possible inconsistencies in some ground-truth labels.
