Tariff monitor

Live U.S. tariff data for manufacturing.

Month-by-month effective calculated-duty rates from 2014-01 through 2026-08: 6,648 observations across 57 manufacturing families, beside the statutory rates of the 2026 Harmonized Tariff Schedule's 1,482 covered lines. Refreshed automatically from USITC data.

Statutory vs effective, explained

  • The statutory schedule reports the General-column rate for each 8-digit line and separately lists Special-program rates and Chapter 99 references. References are not proof that an additional duty applies to a particular entry.
  • The observed effective rate is USITC reported calculated duty divided by covered customs value. Its difference from an unweighted statutory line summary can reflect product, origin, preference, exclusion, and other entry mix; it is not a policy decomposition.
  • Reference statistics derived from USITC published data. Not a customs ruling. MFN-Free and Special-rate fields describe statutory line coverage only; final entry liability requires origin, date, eligibility, exclusions and other transaction facts. Calculated Duties are statistical estimates, not a cash-collections ledger. Confirm classification, origin, program eligibility, and final entry liability with a licensed customs broker.
