From MFG Calcs data: Robots and automated machinery

U.S. imports of robots and automated machinery (heading 8479) came to $12.79B in 2025, with $1.74B in calculated duty: an effective duty of 13.6%, every duty included.

Effective duty in Sep 2026: 12.6%, against 21.1% in Sep 2025.

Largest sources in 2025: Germany $2.44B at 11.3% effective duty; Canada $1.56B at 2.4% effective duty; China $1.22B at 46.8% effective duty; South Korea $1.04B at 7.0% effective duty; Mexico $1.04B at 6.1% 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.
