HS Classification

The customs nomenclature layer. One classification drives duty rate, import/export controls, dangerous-goods rules, and product restrictions — so the code must be defensible, not guessed. This skill classifies from a part number, description, and composition using the General Rules of Interpretation, reconciles the code across national nomenclatures, and routes the result to the regimes it unlocks.

Boundary: customs-and-trade owns duty calculation, landed cost, dual-use and sanctions screening; dangerous-goods-transport owns UN transport rules; the vertical skills own product safety. This skill owns the classification itself — the input every one of those depends on.
