Industrial Furnaces and Ovens: Statutory & Effective Tariff Rates
USITC Column 1 General rates for 18 industrial furnaces and ovens HTS lines (parseable range 0%–4.2%). Effective rate Jun 2026: 9.98%; monthly history since 2023.
The short answer
- The observed effective calculated-duty rate on U.S. imports of industrial furnaces and ovens was 9.98% in Jun 2026, up from 8.59% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0%–4.2% across 18 HTS lines in the 2026 schedule; individual lines are called “Free” only when the official General field is literally Free, which still does not determine a shipment’s final duty. 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 a parseable Column 1 General range of 0%–4.2% in the 2026 schedule. “Free” means the official General field is literally Free for that line; it does not determine final entry liability.
Observed calculated-duty data
- Latest month on record (2026-06): 9.98% effective on $95.9M of imports, versus 8.59% in the same month a year earlier. The monthly archive holds 42 observations from 2023-01 through 2026-06.
- In 2025, U.S. imports for consumption in this family totaled $1.3B in customs value, with $129.3M in USITC reported calculated duty on $1.3B of covered customs value: an effective calculated-duty rate of 9.65%. The aggregate reflects the recorded entry mix but does not attribute the result to a specific legal provision.
- A year earlier the effective calculated-duty rate was 2.46%, so the observed rate rose 7.2 points.
- Top source countries in 2025: Germany ($228.7M at 6.52%), China ($171.1M at 29.54%), Japan ($133.9M at 4.08%), Italy ($121.3M at 7.82%), Canada ($108.1M at 1.4%).
- Reported freight and insurance equaled 3.93% of covered customs value in 2025 ($40.3M total); charge coverage was 76.5% of customs value, from USITC DataWeb. It is shown alongside the effective calculated-duty rate and is not part of the customs-value duty base.
- For scale, 2025 imports in this family equal 0.3% of the U.S. machinery industry's $448B gross output (2025, BEA).

Frequently asked questions
- What is the U.S. tariff rate on industrial furnaces and ovens? USITC calculated duties imply an effective rate of 9.98% in Jun 2026 (calculated duties ÷ covered customs value, USITC DataWeb). The parseable Column 1 General line-rate range is 0%–4.2%; individual lines are called “Free” only when the official General field is literally Free, and product, origin, preference and tariff mix can contribute to the observed-rate difference.

About this data
- 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.
