From MFG Calcs data: Measuring and inspection instruments

U.S. imports of measuring and inspection instruments (headings 9026, 9031) came to $11.20B in 2025, with $1.14B in calculated duty: an effective duty of 10.2%, every duty included.

Effective duty in Sep 2026: 9.2%, against 15.0% in Sep 2025.

Largest sources in 2025: Mexico $1.93B at 3.0% effective duty; Germany $1.73B at 9.3% effective duty; Japan $1.15B at 8.3% effective duty; Canada $816M at 5.4% effective duty; China $760M at 44.0% 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.
