Search MFG Calcs' library of 5,400+ manufacturing calculators (machining, molding, welding, OEE, cost estimating, energy, quality, maintenance, and more). Returns matching calculators with their tool slug for run_calculator.

Get a calculator's inputs (labels, units, defaults) and formula before running it. Use the tool slug from search_calculators.

Run a manufacturing calculation. Provide inputs by field key or slugified label (see get_calculator); missing inputs use the calculator's documented defaults. Returns labeled results with units, the formula, and a citation URL that should be shared with the user.

Look up current U.S. import tariff rates on manufacturing materials, components, and equipment: statutory HTS duty rates (MFN, special programs, Section 301/232 flags) and the effective rate importers actually paid (calculated duties / customs value), plus the implied import price ($/kg or $/unit) f

Get the U.S. Manufacturing Effective-Tariff Index: the empirical effective tariff rate U.S. manufacturers actually pay (total calculated duties / total customs value) across a constant manufacturing panel, monthly since 2014-01, rebased to an index (base = 100).

Rank the source countries for a U.S. manufacturing import family by fully-loaded landed cost, to answer 'where is it cheapest to source X from?'. Each lane's effective duty and freight share are real USITC DataWeb figures; uplift = (1 + duty) x (1 + freight). Where the family has an implied unit pri

Get the Reshoring Readiness Index (RRI) for a U.S. manufacturing import family, to answer 'should the US reshore X?' / 'how strong is the case to bring X production home?'.

Get the Duty-Free Route Badge: for every tracked U.S. manufacturing family, whether a duty-free import route exists on the base tariff schedule — a line already free to all origins (MFN-free), or a reciprocal free-trade-agreement preference that zeroes the MFN duty for a partner country — and how th
