Industrial Furnaces and Ovens: Statutory & Effective Tariff Rates

Statutory HTS duty rates for 18 industrial furnaces and ovens tariff lines (MFN Free–4.2%), from USITC. Effective rate May 2026: 9.9%; monthly history since 2023.

The short answer

  • The effective U.S. tariff on industrial furnaces and ovens was 9.9% in May 2026, down from 10.7% a year earlier — calculated duties actually paid divided by customs value, from USITC data. The statutory MFN rate is Free–4.2% across 18 HTS lines in the 2026 schedule. Germany is the largest source, holding 17.1% of 2025 imports.

Statutory rates from the schedule

  • Gas and electric furnaces, ovens, and induction heating — melting, heat-treating, curing, and drying at temperature. This family covers HTS headings 8417, 8514: 18 eight-digit rate lines with MFN (column 1, general) rates of Free–4.2% in the 2026 schedule.
  • Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.88.01) that apply on top of the MFN column.
