From MFG Calcs data: Switchgear, connectors, and controls

U.S. imports of switchgear, connectors, and controls (headings 8535, 8536, 8537, 8538) came to $42.13B in 2025, with $4.72B in calculated duty: an effective duty of 11.2%, every duty included.

Effective duty in Sep 2026: 10.2%, against 14.4% in Sep 2025.

Largest sources in 2025: Mexico $15.68B at 3.7% effective duty; China $3.54B at 50.9% effective duty; Canada $2.75B at 3.1% effective duty; Germany $2.60B at 10.9% effective duty; Japan $1.75B at 10.4% 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.
