Hscodecomp Eval

---
name: hscodecomp-eval
description: This benchmark evaluates deep search agents' ability to perform multi-hop reasoning across hierarchical tariff rules to predict 10-digit Harmonized System Codes (HSCode) from noisy product descriptions and images. It probes rule-based reasoning, agentic knowledge utilization, and handling of vague or implicit classification logic. Use when the user wants to benchmark on HSCodeComp, or asks about evaluating this task. Reports 10-digit accuracy.

## What this evaluates

This benchmark evaluates deep search agents' ability to perform multi-hop reasoning across hierarchical tariff rules to predict 10-digit Harmonized System Codes (HSCode) from noisy product descriptions and images. It probes rule-based reasoning, agentic knowledge utilization, and handling of vague or implicit classification logic.

## Datasets

- **HSCodeComp** — total ?; splits: test (-1)

## Metrics

- `10-digit accuracy` **(primary)** — range: percent
  - Calculated as the percentage of test instances where the model's predicted 10-digit HSCode exactly matches the ground truth code.

## Input / output format

**Input**: Textual product description and optionally product images.

**Output**: A single 10-digit HSCode enclosed in \boxed{...} format.

## Scoring recipe

```python
def compute_accuracy(predictions, golds):
    correct = 0
    for pred, gold in zip(predictions, golds):
        pred_code = pred.replace('\\boxed{', '').replace('}', '').strip()
        if pred_code == gold.strip():
            correct += 1
    return (correct / len(golds)) * 100
```

## Common pitfalls

- Including hierarchical decision rules (DR) in the prompt actually decreases agent accuracy, contrary to intuition.
- Full webpage visiting tools overwhelm agents with irrelevant content, reducing accuracy compared to using search engine snippets.
- Closed-source agents were evaluated on a small manual subset (49 examples), which may not be directly comparable to the full automated test set.

## Evidence (verbatim from paper)

> All systems produce standardized outputs: a single HSCode in \boxed{...} format. ... The best baseline, SmolAgent (GPT-5 VLM version), achieves only 46.83% 10-digit accuracy, which remains substantially below the 95% accuracy achieved by experienced human experts.
