From MFG Calcs data: Molds and die sets

U.S. imports of molds and die sets (heading 8480) came to $2.28B in 2025, with $321M in calculated duty: an effective duty of 14.1%, every duty included.

Effective duty in Sep 2026: 14.5%, against 21.2% in Sep 2025.

Largest sources in 2025: Canada $848M at 0.9% effective duty; China $348M at 54.2% effective duty; Germany $190M at 11.8% effective duty; Japan $133M at 10.0% effective duty; South Korea $129M at 9.7% 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.
