From MFG Calcs data: Metal-cutting machine tools

U.S. imports of metal-cutting machine tools (headings 8456, 8457, 8458, 8459, 8460, 8461) came to $4.34B in 2025, with $410M in calculated duty: an effective duty of 9.4%, every duty included.

Effective duty in Sep 2026: 11.7%, against 15.9% in Sep 2025.

Largest sources in 2025: Japan $1.16B at 5.0% effective duty; Germany $954M at 8.3% effective duty; South Korea $472M at 8.0% effective duty; Italy $326M at 9.6% effective duty; Taiwan $259M at 13.1% 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.
