## Why tariff_arbitrage_finder is rated Low

The tool reads and analyzes trade data to identify reclassification opportunities, producing informational output (alternative codes, potential savings). It does not itself execute any reclassification, file customs declarations, or move money.

From the tool's own definition: "Analyzes product HS codes against WTO TFA and USA Trade Online data to find lower-duty classifications... Outputs: potential duty savings, alternative HS codes, and compliance considerations"
