Unmeasured means there is not enough evidence to decide. How these checks work
Start using Gateway Lines Tariff
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

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. Not charged: it does not use a duty lookup.
DiscoveredCalculate 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, part of the duty is undetermined (AD/CVD deposits, or a per-unit duty that needs a quantity) and the amounts are provisional; convey that the estimate is incomplete, and read duty_total_bound for whether the total is a minimum. 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, and neither is the same lookup repeated within ten minutes.
DiscoveredList US trade policy changes Gateway has published since a given date: new tariff actions, rate changes, effective dates and expirations, each with its official source. Also returns, under upcoming, earlier entries for changes announced or proposed but not yet in force. Use to answer "what changed recently" or "what is coming". Not charged: it does not use a duty lookup.
