From MFG Calcs data: Technical and refractory ceramics

U.S. imports of technical and refractory ceramics (headings 6903, 6909) came to $1.29B in 2025, with $129M in calculated duty: an effective duty of 10.0%, every duty included.

Effective duty in Sep 2026: 11.1%, against 13.7% in Sep 2025.

Largest sources in 2025: Japan $408M at 8.7% effective duty; Mexico $309M at 0.1% effective duty; Germany $114M at 10.5% effective duty; China $98.3M at 45.8% effective duty; Poland $52.3M 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.
