From MFG Calcs data: Carbon products and insulators

U.S. imports of carbon products and insulators (headings 8545, 8546, 8547) came to $1.26B in 2025, with $224M in calculated duty: an effective duty of 17.8%, every duty included.

Effective duty in Sep 2026: 16.0%, against 21.6% in Sep 2025.

Largest sources in 2025: China $277M at 50.0% effective duty; Mexico $168M at 3.2% effective duty; India $144M at 15.3% effective duty; Japan $119M at 8.7% effective duty; Germany $91.2M at 7.4% 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.
