Molds and die sets: statutory & effective tariff rates
Statutory HTS duty rates for 12 molds and die sets tariff lines (MFN Free–3.8%), from USITC. Effective rate May 2026: 14.6%; monthly history since 2014.
Statutory rates from the schedule
- Injection molds, die-casting dies, compression molds, and die sets — the tooling behind every molded and stamped part. This family covers HTS heading 8480: 12 eight-digit rate lines with MFN (column 1, general) rates of Free–3.8% in the 2026 schedule.
- Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.88.03) that apply on top of the MFN column.
What importers actually paid
- Latest month on record (2026-05): 14.6% effective on $153.0M of imports, versus 13.84% in the same month a year earlier. The monthly archive holds 149 observations from 2014-01 through 2026-05.
- In 2025, U.S. imports for consumption in this family totaled $2.3B in customs value and paid $321.0M in calculated duties: an effective tariff rate of 14.1%. The effective rate captures Section 301/232 overlays, exclusions, and special-program use that the statutory column cannot.
- A year earlier the effective rate was 4.97%, so the duty burden rose 9.1 points.
- Top source countries in 2025: Canada ($847.9M at 0.91%), China ($348.1M at 54.17%), Germany ($189.6M at 11.84%), Japan ($133.0M at 10.04%), South Korea ($128.9M at 9.72%).
