3landed_cost
Calculate US import duty and landed cost estimates. Give hts_code when you know it and this returns the calculated base duty and trade actions (Section 301, Section 232, Section 338, AD/CVD and others), estimated duty, fees and import cost. When estimate_status is partial, AD/CVD is undetermined and the amounts are provisional; convey that the estimate is incomplete. Give product instead and it returns candidate HTS codes WITHOUT pricing, because the classification decides the duty and guessing it produces confidently wrong numbers: confirm the right code with the user, then call again with hts_code. The candidate step is not charged.
classify_hts
Find the US Harmonized Tariff Schedule classification for a product. Returns candidate HTS codes with their official descriptions and base duty rates. Use when the user wants the code itself rather than a cost.
policy_changes_since
List US trade policy changes Gateway has published since a given date: new tariff actions, rate changes, effective dates and expirations. Use to answer "what changed recently" or "what is coming".
