From MFG Calcs data: Gears and power transmission

U.S. imports of gears and power transmission (heading 8483) came to $10.82B in 2025, with $1.82B in calculated duty: an effective duty of 16.8%, every duty included.

Effective duty in Sep 2026: 17.1%, against 28.8% in Sep 2025.

Largest sources in 2025: Germany $1.35B at 14.7% effective duty; China $1.26B at 51.0% effective duty; India $1.24B at 17.3% effective duty; Japan $1.14B at 14.2% effective duty; Mexico $1.11B at 8.1% 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.
