Copper Semi-Finished Products: Statutory & Effective Tariff Rates

USITC Column 1 General rates for 50 copper semi-finished products HTS lines (parseable range 1%–3%). Effective rate Jun 2026: 41.16%; monthly history since 2014.

The short answer

  • The observed effective calculated-duty rate on U.S. imports of copper semi-finished products was 41.16% in Jun 2026, up from 1.56% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 1%–3% across 50 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. Canada is the largest source, holding 25.8% of 2025 imports.

Statutory rates from the schedule

  • Copper bar, profile, wire, plate, sheet, foil, and tube — busbar, harness, and heat-exchanger stock. This family covers HTS headings 7407, 7408, 7409, 7410, 7411: 50 eight-digit rate lines with a parseable Column 1 General range of 1%–3% 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): 41.16% effective on $376.2M of imports, versus 1.56% 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 $5.4B in customs value, with $580.4M in USITC reported calculated duty on $5.4B of covered customs value: an effective calculated-duty rate of 10.82%. 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 0.99%, so the observed rate rose 9.8 points.
  • Top source countries in 2025: Canada ($1.4B at 2.59%), Germany ($631.7M at 13.95%), South Korea ($454.2M at 14.11%), Peru ($417.8M at 12.74%), Mexico ($327.4M at 9.88%).
  • Reported freight and insurance equaled 2.27% of covered customs value in 2025 ($94.6M total); charge coverage was 77.6% 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: 23.3725 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 1.7% of the U.S. primary metals industry's $311B gross output (2025, BEA).

Frequently asked questions

  • What is the U.S. tariff rate on copper semi-finished products? USITC calculated duties imply an effective rate of 41.16% in Jun 2026 (calculated duties ÷ covered customs value, USITC DataWeb). The parseable Column 1 General line-rate range is 1%–3%; 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.

  • What is the customs unit value of copper semi-finished products? $23.4/kg in 2025, derived as customs value ÷ reported quantity from USITC DataWeb. It is an aggregate across the family's product and origin mix, not a transaction price or supplier quote.

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.
