TariffWhisperer
End-to-end RAG system over CBP rulings for explainable HTS code recommendations.
🎯The Problem
Tariff classification is evidence-heavy and error-prone. Users need fast retrieval + justification, not just an answer.
💡The Solution
Ingestion: rulings dataset → chunking → embeddings. Retrieval: dense FAISS + BM25 hybrid. Answering: justification summaries + guardrails to avoid hallucinated codes.
✨Key Highlights
- Dense + BM25 hybrid retrieval
- Sub-500ms retrieval latency
- Evidence-based justifications
