Stainless Steel Mill Products: Statutory & Effective Tariff Rates

USITC Column 1 General rates for 33 stainless steel mill products HTS lines (parseable range 0%). Effective rate Jun 2026: 44.2%; monthly history since 2014.

The short answer

  • The observed effective calculated-duty rate on U.S. imports of stainless steel mill products was 44.2% in Jun 2026, up from 34.2% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0% across 33 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. Taiwan is the largest source, holding 17.1% of 2025 imports.

Statutory rates from the schedule

  • Stainless flat-rolled, bar, shapes, and wire — food, medical, and corrosion-critical work. This family covers HTS headings 7219, 7220, 7221, 7222, 7223: 33 eight-digit rate lines with a parseable Column 1 General range of 0% 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): 44.2% effective on $152.2M of imports, versus 34.2% in the same month a year earlier. The monthly archive holds 150 observations from 2014-01 through 2026-06.
  • In 2025, U.S. imports for consumption in this family totaled $2.1B in customs value, with $538.4M in USITC reported calculated duty on $2.1B of covered customs value: an effective calculated-duty rate of 26.03%. 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 7.68%, so the observed rate rose 18.4 points.
  • Top source countries in 2025: Taiwan ($353.9M at 30.81%), Italy ($236.1M at 20.29%), India ($222.4M at 28.64%), Sweden ($120.2M at 28.97%), Germany ($119.1M at 22.35%).
  • Reported freight and insurance equaled 7.59% of covered customs value in 2025 ($117.4M total); charge coverage was 74.8% 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.
  • Customs unit value: 3.462 per kg in 2025, aggregate declared customs value divided by reported quantity across eligible single-unit lines (USITC DataWeb); not a transaction price.
  • For scale, 2025 imports in this family equal 0.7% of the U.S. primary metals industry's $311B gross output (2025, BEA).

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.
