From MFG Calcs data: Copper semi-finished products

U.S. imports of copper semi-finished products (headings 7407, 7408, 7409, 7410, 7411) came to $5.36B in 2025, with $580M in calculated duty: an effective duty of 10.8%, every duty included.

Effective duty in Sep 2026: 41.3%, against 42.3% in Sep 2025.

Largest sources in 2025: Canada $1.38B at 2.6% effective duty; Germany $632M at 13.9% effective duty; South Korea $454M at 14.1% effective duty; Peru $418M at 12.7% effective duty; Mexico $327M at 9.9% effective duty.

These are family totals from U.S. import statistics published through USITC DataWeb, not this heading's rate alone; effective duty is calculated duty as a share of customs value, an estimate, not a ruling.

About these rates

The rates are those printed in the 2026 HTS Revision 23, published by the U.S. International Trade Commission. A 10-digit statistical line takes the rates printed on the 8-digit line above it. Chapter 99 duties (Section 232, Section 301, IEEPA) depend on the product, the origin and the date, are charged on top, and are not included. A code here is a strong lead, not a ruling: confirm it with a customs broker or a CBP binding ruling.
